Marine heatwaves affect breeding, diet and population size but not body condition of a range-edge little penguin colony
B.L. Cannell, William L. Kendall, J.A. Tyne, M. Bunce, Y. Hetzel, D. Murray, B. Radford
2024, Marine Ecology Progress Series (737) 193-213
Significant marine heatwaves (MHWs) developed along the Western Australian coast in 1999 and 2011. Despite ecosystem losses and the southwards occurrence of many tropical fish species during and after the extreme MHW in 2011, there have been few studies on the effects of this MHW on seabirds, and no biological...

John F. Piatt, Mayumi L. Arimitsu, Sarah Ann Thompson, Rob Suryan, Rory Wilson, Kyle Elliott, W.J. Sydeman
2024, MEPS (737) 1-8
Marine heatwaves (MHWs) are characterized by periods of extreme warming of local to basin-scale marine habitat. Effects of MHWs on some seabirds (e.g. mass die-offs) are well documented, but mechanisms by which seabirds respond to MHWs remain poorly understood. Following from a symposium at the 3rd World Seabird Conference, this Theme...

Jake D. Carleen, Danelle M. Larson, Michael J. Anteau, Megan J. Fitzpatrick, Andrew W. Hafs, Carl W. Isaacson, Breanna R. Keith
2024, Wetlands (44)
Fishes have spread into previously fishless wetlands, likely affecting other species. In the Prairie Pothole Region of North America, the invasion of fish into wetlands is facilitated by interactions of altered land use, climate, and hydrology. We aimed to understand the effects of fishes on amphipods,...

The mid-Piacenzian warm period (MPWP, ~3.264–3.025 Ma) has gained widespread interest due to its partial analogy with future climate. However, quantitative data–model comparison of East Asian Summer Monsoon (EASM) precipitation during the MPWP is relatively rare, especially due to problems in decoding the imprint of physical processes to climate signals in...
