Acheampong Atta-Boateng (Yadvinder Malhi/ Tonya Lander/ Thomas Wanger, Westlake University, China)

Ecology and physiology of plant systems' adaptations in modified ecosystems

 

Ache is broadly interested in how human mediated systems like agriculture and urbanization drive eco-evolution through phenotype expressions, environmental feedback strategies and symbiotic biological association. Cauliflory (flower & fruit growth on stems/branches) is thought as an adaptation to optimize cross-pollination or dispersal but can be physiologically costly as in cacao. Ache's DPhil seeks to elucidate the implication of optimizing cacao-pollinator interaction on economic productivity by linking physiological capacity and pollination ecology to pod yields. He's

also testing the effects of non-hormonal biostimulants (n-hB) in regulating premature fruit abortion (self-thinning). Prior to Oxford, he was research director at Yale Urban Ecology & Design Lab, investigating macrophyte thermal tolerance in engineered wetlands for urban cooling. He was also a research technician at the Plant Physiological Ecology Lab at Yale, working on physiological deterrents of citrus ACP vector, stomatal oscillation controls and n-hB growth promoters.

Guilherme Costa Alvarenga

Jaguar ecology and conservation

Gui is a Brazilian biologist and holds a position as DPhil candidate in the Zoology Department at the University of Oxford. Since 2013, he has been working with jaguar (Panthera onca) ecology and conservation mainly in three research lines: (1) population dynamics, (2) habitat use, and (3) human-carnivore conflict.

During his doctorate, Gui will combine three areas of knowledge – movement ecology, human-carnivore conflict, and landscape analysis – developing the first landscape ecological modelled assessment of jaguar population connectivity across the entire geographical range of the species. Landscape modelling based on empirical data, such as GPS-collared animals, are important tools to understand how animals interact with the habitat and, for consequence, to direct conservation actions. His DPhil project, for instance, seeks to reduce anthropogenic impacts on jaguar populations by enlightening core jaguar habitats and key dispersal corridors, as well as testing how future human-induced alterations in the habitat may impact the species on the Continent. Gui's DPhil is a collaboration among WildCRU, Oxford Ecosystems and Mamirauá Institute, sponsored by WildCRU, WFA and WCN.
