Data from: Female butterflies modulate investment in reproduction and flight in response to monsoon-driven migrations

Vaishali Bhaumik & Krushnamegh Kunte
Migratory species may display striking phenotypic plasticity during individual lifetimes. This may include differential investment in body parts and functions, differential resource use and allocation, and behavioural changes between migratory and non-migratory phases. While migration-related phenotypic changes are well-reported, their underlying mechanisms are usually poorly understood. Here we compare individuals from migratory (reproductive diapause) and non-migratory (reproductive) phases of closely related aposematic butterfly species to study how sexual dimorphism and migratory behaviour underlie significant morphological...

Data from: Responses of interspecific associations in mixed-species bird flocks to selective logging

Binod Borah, Suhel Quader & Umesh Srinivasan
1. Non-trophic interactions (or, inter-species associations) play a prominent role in determining community structure and function. Mixed-species bird flocks are networks of non-trophic associations that confer foraging and anti-predator benefits to participant species. Yet, the responses of these interspecific associations to anthropogenic environmental change are poorly understood. 2. Selective logging is pervasive in the tropics, and can affect associations in mixed-species bird flocks by altering resource availability and/or predation risk, or through the altered abundances...

Data from: Experimental evolution of insect immune memory versus pathogen resistance

Imroze Khan, Arun Prakash & Deepa Agashe
Under strong pathogen pressure, insects often evolve resistance to infection. Many insects are also protected via immune memory (‘immune priming’), whereby sub-lethal exposure to a pathogen enhances survival after secondary infection. Theory predicts that immune memory should evolve when the pathogen is highly virulent, or when pathogen exposure is relatively rare. However, there are no empirical tests of these hypotheses, and the adaptive benefits of immune memory relative to direct resistance against a pathogen are...

Data from: Early-life inflammation, immune response and ageing

Imroze Khan, Deepa Agashe & Jens Rolff
Age-related diseases are often attributed to immunopathology, which results in self-damage caused by an inappropriate inflammatory response. Immunopathology associated with early-life inflammation also appears to cause faster ageing, although we lack direct experimental evidence for this association. To understand the interactions between ageing, inflammation and immunopathology, we used the mealworm beetle Tenebrio molitor as a study organism. We hypothesized that phenoloxidase, an important immune effector in insect defence, may impose substantial immunopathological costs by causing...

Data from: Playing it safe? behavioural responses of mosquito larvae encountering a fish predator

Karthikeyan Chandrasegaran, Avehi Singh, Moumita Laha & Suhel Quader
Predation is a strong selective force that affects prey population and ecosystem dynamics. Detecting predators and associated levels of threat is crucial to prey responses. Once a predator is detected, anti-predatory responses improve the chances of survival of prey. We used Aedes aegypti larvae to study behavioural responses to predation threat from guppies (Poecilia reticulata). Specifically, we tested the relative importance of chemical cues, both in isolation and in combination with physical cues, in eliciting...

Data from: Savannahs of Asia: evidence for antiquity, biogeography and an uncertain future

Jayashree Ratnam, Kyle W. Tomlinson, Dina N. Rasquinha & Mahesh Sankaran
The savannahs of Asia remain locally unrecognized as distinctive ecosystems, and continue to be viewed as degraded forests or seasonally dry tropical forests. These colonial-era legacies are problematic, because they fail to recognize the unique diversity of Asian savannahs and the critical roles of fire and herbivory in maintaining ecosystem health and diversity. In this review, we show that: the palaeo-historical evidence suggests that the savannahs of Asia have existed for at least 1 million...

Data from: Impact of wild prey availability on livestock predation by snow leopards

Kulbhushansingh R. Suryawanshi, Stephen M. Redpath, Yash Veer Bhatnagar, Uma Ramakrishnan, Vaibhav Chaturvedi, Sophie C. Smout & Charudutt Mishra
An increasing proportion of the world's poor is rearing livestock today, and the global livestock population is growing. Livestock predation by large carnivores and their retaliatory killing is becoming an economic and conservation concern. A common recommendation for carnivore conservation and for reducing predation on livestock is to increase wild prey populations based on the assumption that the carnivores will consume this alternative food. Livestock predation, however, could either reduce or intensify with increases in...
