“…While the inventories of most invertebrate communities are often doomed to remain incomplete in practice -due to their usually high species richness including numerous rare species -the exhaustive sampling of vertebrates and, here of frog communities, is usually less out of reach. Thus, among the eight frog communities sampled by Katwate, Apte & Raut [3] in northern-western Ghats of India, five may be considered as already virtually exhaustive while the other three prove being only moderately incomplete (from 80% to 85% completeness: Table 1) but nevertheless require numerical extrapolation. Total species richness levels, either recorded (communities A, C, D, E, G) or extrapolated (communities B, F, H), range from 10 to 17 species.…”

“…Hereafter, I report on the analysis of the inventories of eight frogs communities originally sampled by Katwate, Apte & Raut [3] in northernwestern Ghats of India. Among these eight inventories, five may be considered quasi exhaustive (since no singleton is actually subsisting in the samples), while the other three inventories remain more or less incomplete and thus require the implementation of numerical extrapolation to unveil the complete range of species abundance distribution.…”

Estimating True Species Richness and the Degree of Hierarchical Structuring of Species Abundances in Eight Frog Communities from the North-Western Ghats of India

The Distribution of Species Abundances within natural communities – when properly analysed – can provide essential information regarding general aspects of the internal organisation of these communities. In particular, true species richness on the one hand and the intensity of the process of hierarchical structuring of species abundances on the other hand may be estimated independently and, thereby, can provide truly complementary information. In turn, specific issues may thereby be addressed. For example, whether one unique dominant factor or numerous combined factors are involved in the structuring process of a community can be tested contradictorily. Although these methods are not new conceptually, their implementation in common practice remains scarce. The reason is that the relevant implementation of these methods requires to be sure that virtually all member-species in the community have been sampled. As exhaustive samplings often reveal difficult to achieve in practice, an appropriate, least-biased procedure of numerical extrapolation of incomplete inventories is imperatively required. Considering the steadily increasing threats to the environment and biodiversity, especially facing the on-going climatic change, time has come now with ever greater urgency to go beyond the apparent limits of non-exhaustive sampling and make the most of what is available in terms of recorded field data, whatever the degree of incompleteness of species inventories. As a modest and limited attempt to concretise this wish at the local level, I try, hereafter, to highlight the importance of additional information that may be unveiled through adequate post-analysis of a set of eight frog communities, recently inventoried by Katwate, Apte & Raut in an amphibian hot-spot in the north-western Ghats of India. At last, the likely variations of both total species richness and the intensity of hierarchical structuring of species abundance are simulated as an answer to the steadily increasing influence of the ongoing climatic change.

“…Lekhak and Yadav 2012;Watve 2013). The rate of species discovery and endemicity on these plateaus is high (Katwate et al 2013;Watve 2013;Rahangdale and Rahangdale 2014;Thorpe and Watve 2016;Seshadri et al 2016), possibly due to the presence of several microhabitats such as shallow perennial streams, rocky crevices, and soil-filled depressions (Sreejith et al 2016;Thorpe et al 2018). Recently described frog species, such as Microhyla kodial Vineeth, Radhakrishna, Godwin, Anwesha, Rajashekhar & Aravind, 2018, Microhyla laterite Seshadri, Singal, Priti, Ravikanth, Vidisha, Saurabh, Pratik & Gururaja, 2016 and Euphlyctis karaavali Priti, Naik, Seshadri, Singal, Vidisha, Ravikanth & Gururaja, 2016 have been discovered from the Karnataka Plateau in the last five years (Priti et al 2016;Seshadri et al 2016;Vineeth et al 2018).…”

Lateritic plateaus of India are geographically and ecologically complex plateaus that support endemic flora and fauna. However, despite their uniqueness they are termed as “wastelands”. The plateaus’ overall treeless structure makes them susceptible to developmental activities like infrastructure growth, waste dumping, and urbanization. This paper presents a list of anurans compiled from surveys carried out in the years between 2016 and 2018 in the town of Manipal, a predominant lateritic landscape on the west coast of India. The list comprises of 19 species belonging to five different families, includes notes on microhabitat structure and associated species. We also present descriptions of malformed frogs recorded during the surveys. The growing demands for urbanization, presence of malformed frogs, and habitat complexities that support species densities highlight the need to re-evaluate our understanding towards these plateaus. We express our concern towards the need for conservation of these lesser known amphibian habitats.

The Western Ghats (WG) mountain chain in peninsular India is a global biodiversity hotspot, one in which patterns of phylogenetic diversity and endemism remain to be documented across taxa. We used a well-characterized community of ancient soil predatory arthropods from the WG to understand diversity gradients, identify hotspots of endemism and conservation importance, and highlight poorly studied areas with unique biodiversity. We compiled an occurrence dataset for 19 species of scolopendrid centipedes, which was used to predict areas of habitat suitability using bioclimatic and geomorphological variables in Maxent. We used predicted distributions and a time-calibrated species phylogeny to calculate taxonomic and phylogenetic indices of diversity, endemism, and turnover. We observed a decreasing latitudinal gradient in taxonomic and phylogenetic diversity in the WG, which supports expectations from the latitudinal diversity gradient. The southern WG had the highest phylogenetic diversity and endemism, and was represented by lineages with long branch lengths as observed from relative phylogenetic diversity/endemism. These results indicate the persistence of lineages over evolutionary time in the southern WG and are consistent with predictions from the southern WG refuge hypothesis.The northern WG, despite having low phylogenetic diversity, had high values of phylogenetic endemism represented by distinct lineages as inferred from relative phylogenetic endemism. The distinct endemic lineages in this subregion might be adapted to life in lateritic plateaus characterized by poor soil conditions and high seasonality.Sites across an important biogeographic break, the Palghat Gap, broadly grouped separately in comparisons of species turnover along the WG. The southern WG and Nilgiris, adjoining the Palghat Gap, harbor unique centipede communities, where the causal role of climate or dispersal barriers in shaping diversity remains to be investigated. Our results highlight the need to use phylogeny and distribution data while assessing diversity and endemism patterns in the WG.
