Simulated ecology-driven sympatric speciation
We introduce a multi-locus genetically acquired phenotype, submitted to mutations and with selective value, in an age-structured model for biological aging. This phenotype describes a single-trait effect of the environment on an individual, and we study the resulting distribution of this trait among the population. In particular, our simulations show that the appearance of a double phenotypic a...

متن کاملThe Cognitive Ecology of Dolphin Social Engagement
Investigating social cognition in dolphins is a complex, demanding task. Alien in senses, form, and habitat, dolphins are challenging to comprehend and difficult to study. As the previous chapters in this book have made clear, they are also sophisticated, innovative creatures whose cognition we have only just begun to understand. “Cognitive Ecology” (Hutchins, 2010a, 2014) is a transformative n...
متن کاملResearch Article: Feed comparison and feeding ecology in five sympatric teleost species of the northern Oman Sea
Investigating the relations and mechanisms of coexistence among sympatric species is essential to comprehend their ecological roles in the food webs. In the present study, the diet and trophic interactions of 5 abundant teleost species coexisting in the northern Oman Sea were examined using stomach contents analyses. The cumulative prey curves showed that the sample size of each studied species...
متن کاملGanges River dolphin: an overview of biology, ecology, and conservation status in India.
Ganges River dolphin, Platanista gangetica gangetica, is one of the three obligatory freshwater dolphins in the world and is distributed in the Ganges-Brahmaputra-Meghna and Sangu-Karnaphuli River systems in India, Nepal, and Bangladesh. This species is facing considerable threats to its survival, and its population has dwindled from 4000 to 5000 in the early 1980s to 3500 in 2014 in the distri...
