New publication alert: Insights into riverscape dynamics with the hydrological, ecological and social dimensions for water sustenance

RiverScape

Riverine ecosystems encompass ecological, social and economic processes (ecosystem functions) that interconnect biotic components and provide goods and services for the society. Degradation of these vital ecosystems has been the primary cause for increasing water insecurity, raising the need for integrated solutions to freshwater management. 

Snake venom study reveals troubling shortcomings in antivenom therapy in India

Commercially available antivenoms in India can be ineffective in treating bites from certain medically important yet neglected snakes, a study conducted by the Evolutionary Venomics Lab (www.venomicslab.com), has shown. These so called the ‘neglected many’, are snakes whose bites are harmful to humans, yet remain poorly studied.

New publication: Past climate change and the diversification of geckos from Peninsular India.

geckos

Around 33.5 million years ago, during the Eocene–Oligocene period, there was an abrupt shift towards a cooler drier climate. This resulted in a corresponding shift in biological diversity globally. In Peninsular India, the study of fossil pollens suggests a shift from wet rainforest vegetation to dry and seasonal species during this period. However, the grassland and open habitats that dominate the region today expanded relatively recently as a result of the Late Miocene aridification ~ 11 million years ago.

New species of tree crickets from Mexico named after CES alumna Natasha Mhatre

The Otomi tree cricket (Oecanthus mhatreae sp. nov.) which was recently described from the tropical deciduous forests of central Mexico has been named after a former CES student – Dr. Natasha Mhatre.  

Natasha gives us a behind-the scenes peek into how a part of the natural world came to bear her name. Read the full story here: https://twitter.com/NatashaMhatre/status/1167118606125195264

New publication: Morphological diversification of geckos from Peninsular India

Morphology

Studying adaptive radiations, such as Darwin's finches from the Galápagos Islands, can give us key insights into generalities of ecomorphological diversification. This paper from the Karanth lab examines morphological diversification in Hemidactylus geckos from Peninsular India that occur in a wide range of microhabitats.
