The Rare or Threatened Australian Plants (ROTAP) list and associated coding system was developed and has been maintained by CSIRO since 1979, and lists taxa that are Presumed Extinct, Endangered, … The Rare or Threatened Australian Plants (ROTAP) list and associated coding system was developed and has been maintained by CSIRO since 1979, and lists taxa that are Presumed Extinct, Endangered, Vulnerable, Rare or Poorly Known at the national level. This edition provides the most up-to-date list for conservation purposes. A significant number of endangered and Vulnerable taxa are included, which have not yet been considered for inclusion on either the Australian and New Zealand Environment and Conservation Council list or the Commonwealth's Schedule 1. This is the first ROTAP publication to include subspecies and varieties, and the list now includes 5031 taxa. There have also been at least 3270 amendments to data for listed taxa. A total of 2012 additional records of regional data for tax already listed has been included. A key factor in the development of public opinion, and the design of effective management schemes, lies in the production of accurate data to tell the story. What is threatened? Where is it found? These are two of the most fundamental questions to answer before any strategic plans can be drawn up. Obtaining such apparently simple statistics is a huge task. Rare or Threatened Australian Plants is therefore an important reference for the national status of threatened species, particularly for Rare and Poorly Known species.

Nowadays, species taxonomy is confronted with the challenge to fully incorporate new theory, methods and data from disciplines that study the origin, limits and evolution of species.Integrative taxonomy has been proposed as a framework to bring together these conceptual and methodological developments. Here we review perspectives for an integrative taxonomy that directly bear on what species are, how they can be discovered, and how much diversity is on Earth.We conclude that taxonomy needs to be pluralistic to improve species discovery and description, and to develop novel protocols to produce the much-needed inventory of life in a reasonable time. To cope with the large number of candidate species revealed by molecular studies of eukaryotes, we propose a classification scheme for those units that will facilitate the subsequent assembly of data sets for the formal description of new species under the Linnaean system, and will ultimately integrate the activities of taxonomists and molecular biologists.

In soil, earthworms represent the largest component of the animal biomass and are commonly termed ‘ecosystem engineers’. This review considers the contribution of earthworms to ecosystem services through pedogenesis, development of soil structure, water regulation, nutrient cycling, primary production, climate regulation, pollution remediation and cultural services. Although there has been much research into the role of earthworms in soil ecology, this review demonstrates substantial gaps in our knowledge related in particular to difficulties in identifying the effects of species, land use and climate. The review aims to assist people involved in all aspects of land management, including conservation, agriculture, mining or other industries, to obtain a broad knowledge of earthworms and ecosystem services.

Laboratory experiments were conducted to investigate the survival of P. sansibaricus at five different concentrations of Al2O3 NPs (50 mg kg⁻¹, 100 mg kg⁻¹, 300 mg kg⁻¹, 650 mg kg⁻¹, and 1000 mg kg⁻¹) over varying treatment durations (7 days, 14 days, 21 days, 28 days, and 52 days). Our study found that the survival rate of earthworms was 100% in the control group and at the low concentration (50 mg kg⁻¹) treatment. However, mortality increased significantly as the concentration of Al2O3 NPs increased. The average survivability at the doses of 100, 300, 650, and 1000 mg kg⁻¹ of Al2O3 NPs was 88.8%, 76.2%, 64.8%, and 53.2%, respectively. Notably, there was no significant difference in earthworm mortality across the different treatment durations.

This study investigated the diversity of earthworm species found in banana and guava orchards in Nakhon Pathom, Thailand, where 166 samples were collected. The results showed that 56.63% of earthworms were in the adult stage. In the banana orchard, researchers identified two families and four species: from the family Megascolecidae, they found Amynthas alexandri, Metaphire posthuma, and Polypheretima elongata, along with one species from the family Moniligastridae, Drawida sp. In the guava orchard, two families and two species were identified: from the family Megascolecidae, Metaphire posthuma, and from the family Moniligastridae, Drawida sp. Fungi isolated from the intestines of earthworms, precisely the strains EW2, EW3, EW6, EW13, EW16, EW23, EW25, EW26, EW28, EW38, EW39, EW40, EW41, EW43, and EW44, have demonstrated the ability to produce cellulase. Among these, the fungus EW41 exhibited the highest cellulase activity, measuring 32.97 units per milliliter at an optimal temperature of 60 ℃ and a pH of 5.0. This study highlights that most earthworm species in agricultural soils belong to the family Megascolecidae. Furthermore, earthworms play a crucial role in enhancing the chemical properties of the soil. The cellulolytic fungi present in earthworm intestines contribute to the natural decomposition of organic matter, thereby promoting soil health by converting plant residues into nutrient-rich compost. These findings suggest promising applications of earthworm-associated fungi in sustainable agriculture and organic waste management.

The taxonomic classification of earthworms using morphological characteristics requires experts, is difficult, and can require specimen dissection to extract detailed anatomical studies. Molecular techniques are time-consuming and expensive. The objective of this study was to distinguish earthworms belonging to different genera, Eisenia, Dendrobaena, and Lumbricus, using an innovative approach involving machine learning models built based on image texture parameters from individual color channels R, G, B, L, a, b, X, Y, Z, U, V, and S. The earthworms Eisenia fetida, Dendrobaena ssp., and Lumbricus terrestris were used as research materials. Image acquisition was performed using a flatbed scanner on a black background. In the case of each earthworm, 2172 texture parameters from images in individual color channels R, G, B, L, a, b, X, Y, Z, U, V, and S were extracted. Textures after selection were used to develop classification models using machine learning algorithms. The earthworms Eisenia fetida, Dendrobaena ssp., and Lumbricus terrestris were distinguished with the accuracy reaching 100% for models built using Logistic, Ensemble, and Narrow Neural Network. All earthworms were correctly classified. Also, in the case of other models, earthworm classes were distinguished with high accuracies, such as 99% (Naive Bayes, Random Forest, SVM, KNN), 97% (Simple Logistic), and 94% (KStar). For the most important species, E. fetida, the correctness of the species identification was confirmed by direct RNA sequencing. The application of image analysis and machine learning turned out to be a non-destructive, inexpensive, and objective approach to distinguishing earthworms belonging to different genera.

Kanchuria Julka, 1988, is a small genus endemic to the north-eastern region of India, with eight known species. Two new species of the genus, namely Kanchuria tripuraensis Narayanan, Paliwal & Julka, sp. nov., and K. priyasankari Narayanan, Paliwal & Julka, sp. nov., are described from materials collected from the Tripura State in North-eastern India. K. tripuraensis sp. nov. is a unique species of the genus, distinguishable from all other known species by having single ventromedian spermathecae in segments 7 and 8. K. priyasankari sp. nov. belongs to the turaensis-species group characterized by three pairs of spermathecal pores. This group has a total of 5 species, including the new species described herein. Among the congeners of the group, K. priyasankari sp. nov. shows close similarity with K. turaensis Julka, 1988. K. priyasankari sp. nov. can be easily differentiated from the K. turaensis by the small body dimensions and characteristics of the spermathecae. The present work provides detailed descriptions of the new species along with photographs and illustrations of the key characters. A key to species of the genus Kanchuria is also provided. With the discovery of two new taxa, the total number of Kanchuria species has gone up to 10, and megadrile worm diversity reported from the Tripura State has increased to 38.

We have altered the earth climate tremendously, to meet our needs which is affecting innocent fauna badly. They are losing their habitats, essential for their existence, due to widespread industrialization and encroachment, deforestation etc. Data shows that about one million animal and plant species are now threatened; In Arctics, temperatures are increasing at double rate than before. All this is happening too fast. Many animal species are not being able to cope up. We have a responsibility to save suffering fauna; they have the role in ecosystems like seed dispersal, pollination as well as carbon sequestration. Even, if we lose species, we may have to face more zoonotic diseases. Many industries like tourism, will be affected on which many livelihoods depend. Where earth weather systems are interconnected, warming the planet will alter rainfall pattern, animals will have to face more extremes. Aquatic fauna is also suffering and some fish species have to migrate to cooler places. Animals like African elephant, Green Turtles, Giant Pandas and Lemurs have to face more difficulties. Its time that whole world should try to keep global temperature rise under control. Efforts need to be done, to care and protect the innocent suffering fauna by taking preventive measures, bringing awareness and adopting good practices before we lose them..

They are often … Earthworms are one of the major macrofauna of the soil ecosystem. They help in improving soil fertility by their activities and maintaining the biogeochemical cycles of soil. They are often called as ‘friends of farmers’ as their presence makes the soil environment more hospitable for crops and other floral communities. Earthworm population and diversity depend on various edaphic and climatic factors. Among them, soil physicochemical properties play a crucial role. The Present study was conducted in the Gohana region of Haryana to find out the earthworm diversity and factors that can impact the earthworm density. Three different fields, mix crop field (site 1), sugarcane field (site 2) and java plum garden (site 3) were selected for the study. Soil physicochemical properties, viz., temperature, moisture, bulk density, water holding capacity, pH, carbon, organic matter, nitrogen, phosphorus, potassium, and sodium were analyzed on a monthly basis from November 2021 to October 2023 and earthworm density and diversity was measured during the rainy season of the year 2022 and 2023. Only three species were reported in the fields, out of which two species, Metaphire posthuma and Lampito mauritii were reported in all fields and Eutyphous incommodus was recorded only at site 3. Pearson correlation was applied using t-test and the results indicated that annual average Nitrogen values have a positive correlation with earthworm density (p<0.025). The correlation of earthworm densities across all fields with the coefficient of variation indicated that temperature negatively impacts the earthworm density (p<0.05). The study also indicated that an undisturbed environment is better suitable for earthworms as maximum earthworm density was observed at site 3. It also indicated that field management practices such as tillage and the use of pesticides and fertilizer may have an impact on the earthworm population.

In this paper, we describe Potamophylax rilaensis sp. nov., a new species within this cluster from Bulgaria, which is morphologically most similar to P. juliani Kumanski 1999 (in Kumanski & Malicky 1999) and P. kosovaensis Ibrahimi & Bilalli 2024 (in Ibrahimi et al. 2024). The males of P. rilaensis sp. nov. differ from closest congeners by distinct morphological features, particularly in the shape of the inferior appendages, parameres, and paramere spine pattern. Potamophylax rilaensis sp. nov. was found at two localities in the Rila Mountains, at elevations ranging from 1462 to 1935 m above sea level. With the addition of P. rilaensis sp. nov., there are now eight known species within the P. winneguthi Species Cluster identified from the Balkan Peninsula. A comprehensive overview of species distribution, habitat preferences, and diagnostic features of male genitalia is also provided.

In fact, although they are thought to be the closest relatives of the eukaryotic supergroup SAR (Stramenopiles, Alveolata and Rhizaria), their diversity and biology are largely unexplored: to date, there are only seven described species in three genera, although there are estimated to be hundreds more unknown lineages. Here, we describe the isolation and characterization of two new strains, including a new genus ( Hyaliora molinica gen. et sp. nov.) and a new species ( Telonema blandense sp. nov.), and the re-isolation of a previously characterized telonemid, Telonema subtile , accompanied by new behavioral observations. We present morphological measurements highlighting differences among the isolates and a phylogenetic tree incorporating their 18S rRNA gene sequences. Furthermore, key aspects of their cell biology and structure are highlighted to provide insights into the evolution of TSAR. Since they are relevant not only phylogenetically, but also play a crucial role in food webs with some very abundant representatives in aquatic ecosystems, the findings of this study provide a further sampling and culturing of Telonemia to increase the knowledge of the hidden diversity and evolution of this mysterious group.

Larvae are strictly coprophagous while adults exhibit a varied diet that includes dung, decaying organic matter, and fungi. In mountainous areas, they are present in advanced stages of carcass decomposition, highlighting their ecological relevance as a decomposer. In Navarra (Spain), a unique behavior is reported. It has been observed that A. stercorosus attacked slugs of the genus Arion, which are larger than the beetles, and subsequently nested beneath them. This finding provides new insight into the ecological role of A. stercorosus and expands knowledge about its diet and trophic plasticity.

Their ecological functions disrupted by environmental stresses particularly heavy metal contamination from elements like Zinc (Zn) and Copper (Cu). This study aimed to assess the impact of heavy metals on earthworms and their ability to accumulate Zn and Cu. Earthworms were collected from different agricultural sites and maintained under laboratory conditions for a period of 28 days. Four experimental groups were established. The control group (T0) received no exposure to heavy metals, whereas the treatment groups (T1, T2, and T3) were subjected to increasing concentrations of Zinc (Zn) at 1.5 mg/kg, 2.0 mg/kg, and 2.5 mg/kg and Copper (Cu) at 0.1 mg/kg, 0.2 mg/kg, and 0.3 mg/kg, respectively. Prior to the experiment, all earthworms underwent a one-week acclimatization period in soil trays and were provided with a standard feed. Key parameters assessed included total body weight, length, biomass, cocoon production and population changes. A significant reduction in growth was observed in group T3 (1.098 ± 0.030) reflecting high variability when compared with the other treatments. Survival rates were lowest in T3, where only 5 earthworms survived, while the highest survival was recorded in the control group (T0), where all 15 earthworms remained alive. Cocoon production also declined in T3, with only 2 cocoons produced compared to 8 in the control group. Data were statistically analyzed using one-way ANOVA. Growth and survival rates showed significant declines (P < 0.05), indicating that exposure to higher metal concentrations adversely affected these parameters. However, reproductive output showed no statistically significant difference (P > 0.05).

Although soil … Microorganisms participate in complex interactions involving different kingdoms, so rhizosphere biodiversity mapping is essential for understanding how microbes interact with each other in the soil and with roots. Although soil microbial communities are remarkably diverse and technological advances have provided a high capacity to acquire reliable sequence data, unique microbial taxa in soil, root and rhizosphere samples remain poorly described. For the first time, we organized a consortium to collect soil samples covering all Brazilian biomes, providing a comprehensive and unprecedented view of soil microbial diversity. This understanding is critical, especially within the context of climate change, which affects plant physiology, root exudation and, consequently, the composition and functionality of soil microbial communities. The interactions between soil, roots and rhizosphere are influenced by evolutionary and adaptive forces and shape the production of microbial natural products, which exhibit great therapeutic potential and Mapping and studying rhizosphere microbial biodiversity not only increases our knowledge of soil ecology but also offers valuable insights for developing sustainable practices. We employed both 16S/18S/ITS amplicon and metagenomic short-read shotgun sequencing methods to examine and catalogue the large-scale genomes of culture-independent rhizosphere microbes and their interactions with roots in six terrestrial Brazilian biomes, namely, the Amazon, Atlantic Forest, Cerrado, Caatinga, Pampa and Pantanal. Our results revealed the ubiquity of Proteobacteria, which reflects their adaptability to contrasting environments. Biomes with greater moisture availability, such as the Amazon and Pantanal, exhibited greater diversity and abundance of fast-growing bacteria, such as Proteobacteria, and nutrient cyclers, such as Thaumarchaeota. Arid and semiarid biomes, such as the Caatinga, were dominated by microorganisms tolerant to drought and nutrient-limited environments, such as Actinobacteria. Acidobacteria, which thrive in acidic, nutrient-poor soils, were very abundant in forest biomes. The Planctomycetes phylum also occurred more frequently in areas with a relatively high soil organic matter content, such as the Cerrado. Bacteroidetes was significantly more abundant in Pampa than in the other biomes. The results provide comprehensive insights into soil, root and rhizosphere biodiversity and not only enhance the knowledge of the fundamental biological processes sustaining plant life but also constitute a reliable sequencing databank to address present-day agricultural and environmental challenges.

The key findings are as follows: 1. Perionyx sansibaricus exhibited bimodality in its reproductive strategy, with two peaks observed in December 2021 and July 2022, recording values of 1.06 and 1.28, respectively. 2. The rate of population growth peaked at +3.202 in July 2022, when environmental resistance was at its lowest, and reached a minimum of -0.875 in June 2022. 3. Population density was highest at 9045/m² in August 2022 and lowest at 345/m² in June 2022, with juvenile proportions ranging from 8.33% to 27.70%, immature proportions from 44.50% to 100%, and mature proportions from 16.21% to 31.89%. 4. The biomass of Perionyx sansibaricus peaked at 2111.18 g live weight/m² in August 2022 and dropped to a minimum of 60.38 g live weight/m² in June 2022. High density and rapid reproduction rates confirm that Perionyx sansibaricus is an efficient agent of vermitechnology.

Estos residuos depositados a un lado del arroyo de San Pedro comprenden cuantiosos volúmenes que al estar en contacto con el ambiente y por procesos de meteorización e intemperismo natural promueven la formación del drenaje ácido de mina. El objetivo de esta investigación fue evaluar la concentración de arsénico en sedimentos y suelos rizosféricos, así como a qué fracciones se encuentra preferentemente ligado. Lo anterior a través de cuatro metodologías; concentración total de arsénico, fraccionamiento del As que incluye siete fases: intercambiable, carbonatada, unida a oxihidróxidos de hierro y manganeso, unida a materia orgánica y la fase residual en suelos rizosféricos y sedimentos , fitoaccesibilidad en suelos rizosféricos del arroyo ubicado en Cerro de San Pedro y, finalmente, bioacumulación del arsénico en la especie de Asphodelus fitulosus la cual es nativa del sitio de estudio. Se obtuvo que las concentraciones de arsénico se encuentran por encima de las concentraciones de referencia de la normativa mexicana vigente. La fracción fitoaccesible está asociada a las primeras fracciones minerales solubles, como lo es el As ligado a agua meteórica, intercambiable y carbonatos, además que la especie A. fistulosus bioacumuló mayor arsénico en las raíces que en las hojas.

To better understand the ecological impact of pollutants from uncontrolled landfills and to assess the potential risks they pose to terrestrial ecosystems and public health, soil samples were collected from … To better understand the ecological impact of pollutants from uncontrolled landfills and to assess the potential risks they pose to terrestrial ecosystems and public health, soil samples were collected from uncontrolled landfills in three municipalities of Kinshasa and analyzed for 17 metals and metalloids (including metals Fe, Zn, Mn, Cu, Pb, Cr, Co, Sn, Ni, Cd, Sc, Ag, Mo, and Hg, and metalloids Se, As, Sb) using ICP-MS and AAS. The following decreasing order of elemental concentrations was generally observed in soils: Fe > Zn > Mn > Cu > Pb > Cr > Co > Sn > Ni > Cd > Se > As > Sb > Sc > Ag > Mo > Hg. The Geoaccumulation Index (Igeo) and the Enrichment Factor (EF) indicated very severe to extremely severe soil contamination by metals, with high enhancement of Cu, Zn, As, Ag, Cd, Sb, Pb, and Hg concentrations. Furthermore, several ecotoxicological indices, such as the Potential Ecological Risk Index (RI), highlighted serious soil pollution, particularly in the samples from the landfill receiving industrial waste at Limete municipality. Therefore, the use of these soils from uncontrolled landfills for fertilization of agricultural fields, as farmers currently do, poses a serious risk to public health. Concentrations of metals and metalloids were determined also in the earthworm Hyperiodrilus africanus, collected in the same areas, and the earthworm bioaccumulation factor (on a dry weight basis) displayed values greater than one in most samples and up to 15.3. This bioaccumulation of metals and metalloids from the soil suggests that earthworms can be used as a bioremediation agent for contaminated soils. Based on the results from this research, several recommendations are made to improve the pollution control and to protect public health.
