Characterising range expansion potential of tropical vagrant fishes

A/Prof Will Figueira1, Prof David Booth2, Mr Riccardo Cannas1, Ms Giglia Beretta2, Mr Luke Brown2 1University of Sydney, Sydney, Australia, 2Univeristy of Technology Sydney, Sydney, Australia As oceans warm due to climate change, it is becoming increasingly common to find tropical fish species occurring in temperate habitats.  These vagrant fishes have the potential to greatly…

Range edge dynamics of marine fishes in a global warming hotspot

Alexa Fredston-Hermann1, Dr Malin Pinsky2, Dr Steve Gaines1, Dr Benjamin Halpern1 1University of California Santa Barbara, Santa Barbara, United States, 2Rutgers University, New Brunswick, United States Species around the world are shifting their ranges in response to climate change. Most empirical evidence for these climate-related range shifts comes from measuring the displacement of a population’s…

Decoding climate response: future of native snow trout and non-native brown trout in Himalayan rivers

Dr Vineet Dubey1, Ms Aashna Sharma1, Dr Jeyaraj Johnson1, Dr Kuppusamy Sivakumar1 1Wildlife Institute Of India, Dehradun, India Successfully established wild populations of non-native brown trout (Salmo trutta fario) in higher altitude of Himalaya raise concerns for conservation of native snow trout (Schizothorax richardsonii) species over the past years. As such, assessing the way invasive-exotics…

Tropical butterflies persist in variable environments through morphological and behavioral specialization

Dr Wenda Cheng1, Dr Shuang Xing1, Dr Akihiro Nakamura2, Dr Timothy Bonebrake1 1The University of Hong Kong, Hong Kong S.A.R., China, 2Xishuangbanna Tropical Botanical Garden, CAS, Menglun, China Species are adapted to the environments where they are distributed and tropical species inhabiting stable thermal environments are therefore likely to have low cold tolerance, i.e. “mountain…

Integrating genetic and demographic effects of dispersal on population response to a variable environment

Dr. Allison Dedrick1, Prof Marissa Baskett2 1Rutgers University, Rutgers, United States, 2University Of California, Davis, Davis, United States Dispersal can have counteracting effects on population response to variable and changing environments.  On one hand, dispersal mobilizes individuals and diversity to increase local response to environmental change.  On the other hand, dispersal can synchronize populations and…
