Seshadri’s research featured on

We are playing catch-up on news about Seshadri, one of the PhD students in the Evolutionary Ecology and Conservation Lab who is back in Singapore after spending the summer in India doing field work.


Seshadri’s master’s research on the effects of selective logging on frogs in the Kalakad Mundanthurai Tiger Reserve was recently published in Biotropica and featured on the conservation website The reserve is part of the Western Ghats, which along with Sri Lanka is a biodiversity hotspot that is home to many threatened endemic amphibians. Seshadri found that negative impacts on  densities and community composition of anurans persisted in logged forest even 40 years after moderate logging was ceased.

The degradation from logging has led to the loss of ecological niches – particularly affecting stream- and litter-dwelling species. It appears that anuran assemblages in the region do not recover quickly from habitat degradation due to logging.


Seshadri will continue to work on threatened amphibians in the Western Ghats for his PhD dissertation, focusing on the ecology and behaviour of bamboo nesting frogs. His research will be supported by the Mohamed bin Zayed Species Conservation Fund and Chicago Zoological Fund, which are competitive grants awarded to conservation efforts to save species worldwide.

Congratulations Seshadri!

Abstract: – Infectious diseases are emerging in real time, with the current epidemic of ebola in West Africa taking the headlines at more than 1,900 human deaths over the course of March to September 2014. Infectious disease emergence is a field that spans studies of wildlife, domestic animals, and humans, and is not only relevant in times like this, but also globally important in times of non-crisis. Overall, I will study the linkages between ecological and human systems to understand how these connections and interactions may affect risk of emergence, and ultimately how control and policy may fit in. Factors that are drivers of disease and dynamics may be affected by aspects and behaviors of both human populations and animal populations. The goal is to characterize and manage risk by examining connectedness, risk, and control allocations or actions that may be contributing to disease emergence. In order to capture how various factors may impact risk, this proposed PhD thesis approaches the modeling of the emergence of infectious diseases from multiple scales: global national, continental spatially explicit, regional, and landscape. In the first chapter, global official development assistance will be collated and compared with risk of emergence. The second chapter will look at Africa land use projections as a result of economic development and other ecological factors to understand how development activities may be managed to reduce future risk. The third chapter examines the trade connections in the Southeast Asian region, an area that may be considered a hotspot for biodiversity and development as well as disease emergence. In the last chapter, a case study in Thailand is proposed that follows human movement and connects it to mosquito sampling and clinical records of dengue and malaria in people.
