Introduction
I am interested in the mechanisms that shape the evolution of species and
traits, with specific focus on the role of genome and epigenome evolution. For more information, see crazychipkali.weebly.com

Mountain ranges are hotspots of biodiversity. However, the mechanisms that generate biodiversity patterns in different mountainous regions and taxa are not apparent. The Western Ghats (WG) escarpment in India is a globally recognised biodiversity hotspot with high species richness and endemism. Most studies have either invoked paleoclimatic conditi...
Herpetology in India took off during the British colonial rule with the documentation of herpetofauna. Several studies have outlined the early history of Indian herpetology; however, few have traced the growth of this field since India's independence. We analyse trends in Indian herpetology focusing on taxa, subfields, and authorship over the last...
The Andaman day gecko (Phelsuma andamanensis) is endemic to the Andaman Archipelago, located ~ 6000 km away from Madagascar where the genus Phelsuma likely evolved. We complemented existing phylogenetic data with additional markers to show that this species consistently branches off early in the evolution of the genus Phelsuma, and this early origi...
The Indian egg-eater (Elachistodon westermanni) is a monotypic species of the Genus Elachistodon distributed
across the Indian sub-continent. In Africa, there are 13 species of egg-eating snakes of the Genus Dasypeltis. These two
genera, Elachistodon and Dasypeltis were thought to be closely related due to similar diet specialization, and shared
bi...
Synopsis
Artificial intelligence (AI) is poised to revolutionize many aspects of science, including the study of evolutionary morphology. While classical AI methods such as principal component analysis and cluster analysis have been commonplace in the study of evolutionary morphology for decades, recent years have seen increasing application of dee...
Artificial intelligence (AI) is poised to transform many aspects of society, and the study of evolutionary morphology is no exception. Machine learning-grade methods of AI such as Principal Component Analysis (PCA) and Cluster Analysis have been commonplace in evolutionary morphology for decades, but the last decade has seen increasing application...
Temperature-induced developmental plasticity could allow amphibian larvae to complete metamorphosis successfully despite new thermal challenges and increased desiccation risk due to climate change. Here we investigated how the capacity for temperature-induced developmental plasticity varies with latitude and whether population-specific biogeographi...
The 71 currently known species of dwarf geckos of the genus Lygodactylus are a clade of biogeographic interest due to their occurrence in continental Africa, Madagascar, and South America. Furthermore, because many species are morphologically cryptic, our knowledge of species-level diversity within this genus is incomplete, as indicated by numerous...
A polymath and ahead of his time, Alexander von Humboldt had numerous interests and insights that have shaped modern science. His holistic viewpoint on nature founded the principles of several branches of sciences such as comparative biology, ecology, and biogeography, and inspired scientists who went on to make notable contributions during and aft...
Altered environments in urban areas are known to impact and change animal behaviour. In particular, artificial light at night (ALAN) affects behaviour across taxonomic groups, including reptiles. Geckos in the genus Phelsuma are predominantly diurnal, but some have been documented to alter their foraging behaviour from a diurnal to nocturnal activi...
Phelsuma guttata and Paroedura gracilis are two species of geckos endemic to lowland and mid-elevation rainforests of the northern half of Madagascar's rainforest band. To test for concordant phylogeographic patterns in the two species and to assess intraspecific phylogeny and genetic diversity, we sequenced DNA from two mitochondrial genes (16S an...
Limited gene flow between populations due to geographic distance, presence of barriers or inherent low dispersal ability leads to the formation of genetically structured populations. Strong population structure indicates lowered levels or absence of gene flow which might lead to inbreeding and loss of genetic capacity to recuperate from anthropogen...
We describe a new species of rock-dwelling gecko, Hemidactylus paaragowlipaaragowli sp. nov., from the Agastyamalai Hill Range, in the southern Western Ghats. Morphological and molecular data support the distinctiveness of the species and its close relationship to other large-bodied, tuberculate Hemidactylus spp. from the H. prashadi group from Ind...
The species of Pyrops Spinola, 1839 recorded from the Andaman and Nicobar Islands are
reviewed with a new species, P. azureus sp. nov. is described from North Andaman and
recorded from South Andaman and Long Island based on photographs in nature.
A distribution map of the species is given. The three Pyrops species currently known in the
Archipelago...
Questions
Question (1)
When I run 15 iterations/replicates for every value of K, results from all the 15 runs are not getting saved in the results directory. For some values of K, I get all 15 result files, but for some just 10 or 12. This is becoming a problem when I want to compare same number of runs across different Ks to get the Evanno's delta K values. It would be great if someone could suggest a solution.
Thanks!
Ashwini
