Helping on the move: A theoretical study shows that mobility of organisms can promote cooperation.

Previous studies have argued that movement of organisms typically does not favour animals helping or cooperating each other. Therefore, in species that exhibit collective movement and fission-fusion among groups, cooperation is considered unlikely to occur. In a recent paper published in PLoS Computational Biology, Jaideep Joshi (PhD student), Vishwesha Guttal and collaborators from Germany and USA challenge this common perception.

Small brains, smart solutions: A new study shows that tree crickets manufacture optimal aids for sound amplification

media coverage, ces, iisc, publications

A new study published in the journal eLife shows that tree crickets manufacture surprisingly accurate optimal aids for sound amplification. This work was led by Natasha Mhatre (a former PhD student of CES), Rittik Deb (a recent PhD student of CES), Rohini Balakrishnan and collaborators from UK (Robert Malkin and Daniel Robert).

Fungus-Farming Termites Selectively Bury Weedy Fungi that Smell Different from Crop Fungi by Lakshya Katariya et al., Renee Borges Lab

Lakshya Katariya and colleagues (Renee M Borges’ lab) discover that fungus-farming termites
selectively bury the weedy fungi that smell different from crop fungi

Fresh elephants’ dung reveals stress levels in wild Asian elephants

Recent research findings by a CES Ph.D. student Sanjeeta Sharma Pokharel, Prof. Polani B Seshagiri (MRDG, IISc) and Prof. Raman Sukumar (CES, IISc) show that the stress levels and body condition of elephants varied between seasons. Wild Asian elephants were showed ‘poor’ body condition and were found to be ‘more’ stressed during resource-deficient periods. This pattern was more conspicuous in female Asian elephants.

Study by Pratibha Yadav and Renee Borges shows that insects can smell with their ovipositors

Fig Wasp

The egg laying organ of insects, their ovipositor, is usually believed to only taste via chemical receptors. A recent study by CES PhD student Pratibha Yadav and Prof. Renee Borges shows that insect ovipositor can also sense smell.

Study by Nikita Zachariah, Renee Borges and colleagues reveals that termites build mounds from anything they can chew and move on

Bower bird nests, bee hives and towering termite mounds have always fascinated architects, naturalists and laypersons alike but we barely know how they are built. A study by an interdisciplinary team consisting Nikita Zachariah (a PhD student) and Prof. Renee M Borges from CES, Aritra Das from the Centre for NeuroScience and Prof. Tejas Murthy from the Department of Civil Engineering, IISc offers interesting clues on how termites build huge mounds.
