Eve Davidian: Why do the top dogs get the prettiest ladies? A story of sex, stress and hyena poops

In this new post, Eve Davidian and colleagues explore The interplay between social rank, physiological constraints and investment in courtship in male spotted hyenas. Their study shows that the social and mating system of spotted hyenas may shed some light into the roots of reproductive inequalities in mammalian societies. Toleo la Kiswahili linapatikana hapa. In most animal societies, resources are not shared equally among members … Continue reading Eve Davidian: Why do the top dogs get the prettiest ladies? A story of sex, stress and hyena poops

An English version of this blogpost is available here. Kuna pengo la kiuelewa kuhusu uhusiano kati ya cheo cha mwanaume kijamii na mafanikio yake katika uzazi. Hii ni kwa mujibu wa utafiti nilioufanya na mwenzangu, miongoni mwa wanyama. Utafiti huu unaonyesha kuwa mfumo wa kijamii na kujamiiana wa fisi wenye madoadoa unaweza kutoa mwanga katika kuelewa mienendo ya usawa wa uzazi miongoni mwa jamii za … Continue reading Na Eve Davidian: Hadithi ya mapenzi, msongo na kinyesi cha fisi Ngorongoro

Tara-Lyn Camilleri: Parental sugar consumption modifies offspring life history and physiology

In this blog post, Tara-Lyn Camilleri, a Ph.D. candidate at Monash University in Australia, discusses her newly published paper, “Maternal and paternal sugar consumption interact to modify offspring life history and physiology”. About the paper Varying the environment of an organism can alter their physiology, which in turn alters their development time, lifespan, the rate they reproduce, the survival rate of their offspring, their body … Continue reading Tara-Lyn Camilleri: Parental sugar consumption modifies offspring life history and physiology

Molly Roberts: A network of threads and perspectives, energetic cost of mussel attachment

Emily “Molly” Roberts, postdoctoral fellow at Claremont McKenna College, presents her recent work ‘Resource allocation to a structural biomaterial: induced production of byssal threads decreases growth of a marine mussel, Mytilus trossulus’ where she and her colleagues tested the trade-off between survival and growth of mussels. About the paper This paper is about the energetic ‘investment’ that mussels make to stay anchored to their habitat. … Continue reading Molly Roberts: A network of threads and perspectives, energetic cost of mussel attachment

Mark Wilber: Resistance and tolerance of salamanders to an emerging fungal pathogen

Dr. Mark Wilber, Assistant Professor in the Department of Forestry, Wildlife, and Fisheries at the University of Tennessee, discusses his recently accepted article, “Putative resistance and tolerance mechanisms have little impact on disease progression for an emerging salamander pathogen”, describes his favourite part about being ecologist, and how he got into the field. What is the background behind your paper? Hosts can defend themselves against … Continue reading Mark Wilber: Resistance and tolerance of salamanders to an emerging fungal pathogen
