Marine heatwaves affect breeding, diet and population size but not body condition of a range-edge little penguin colony Marine heatwaves affect breeding, diet and population size but not body condition of a range-edge little penguin colony
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 impacts related to the 1999 MHW have been reported. Using data from 1986-2019...

Mechanisms by which marine heatwaves impact seabirds Mechanisms by which marine heatwaves impact seabirds
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 Section presents recent research to address this...

Turning setbacks into stepping-stones for growth in conservation paleobiology Turning setbacks into stepping-stones for growth in conservation paleobiology
Conservation paleobiology is a cross-disciplinary field that utilizes the geohistorical record of past life on Earth to inform present-day decisions in conservation and restoration and assist in planning for future natural resource management. However, information on how past ecosystems and species responded to environmental change over decadal to millennial timescales is rarely...

Fish invasion of prairie pothole wetlands reduces amphipod abundance, a key vertebrate forage Fish invasion of prairie pothole wetlands reduces amphipod abundance, a key vertebrate forage
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, which are macroinvertebrates that vertebrates rely on as forage. We hypothesized the...

Breeding ecology of White-tailed Hawks (Geranoaetus albicaudatus) on Texas barrier islands Breeding ecology of White-tailed Hawks (Geranoaetus albicaudatus) on Texas barrier islands
The White-tailed Hawk (Geranoaetus albicaudatus) is listed as a state threatened species in Texas. It occupies prairies and savannas of the Gulf Coastal Plain, but also the barrier islands, many of which are exposed to rapid development and other human disturbances. This is a concern as White-tailed Hawks are known to be highly sensitive to nesting disturbance. We examined the breeding...

Importance of a lake-wetland complex for a resilient Walleye fishery Importance of a lake-wetland complex for a resilient Walleye fishery
Wetlands serve as unique habitats that can support high biodiversity. Large-scale loss of wetland habitats can threaten important linkages between lake and wetland habitats that could affect diversity and growth of aquatic organisms. In this study, we compare prey diversity and abundance as well as Walleye (Sander vitreus) diets and condition in a large glacial lake (Lake Kampeska, South...

Assessment of undiscovered conventional oil and gas resources in postsalt reservoirs of the West-Central Coastal Province of Africa, 2022 Assessment of undiscovered conventional oil and gas resources in postsalt reservoirs of the West-Central Coastal Province of Africa, 2022
Using a geology-based assessment methodology, the U.S. Geological Survey estimated undiscovered, technically recoverable mean conventional resources of 10.5 billion barrels of oil and 47.4 trillion cubic feet of gas in postsalt reservoirs within the West-Central Coastal Province of Africa.

Decomposition of physical processes controlling EASM precipitation changes during the mid-Piacenzian: New insights into data–model integration Decomposition of physical processes controlling EASM precipitation changes during the mid-Piacenzian: New insights into data–model integration
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 the records. In this study...

Origins and nature of large explosive eruptions in the lower East Rift Zone of Kīlauea volcano, Hawaii: Insights from ash characterization and geochemistry Origins and nature of large explosive eruptions in the lower East Rift Zone of Kīlauea volcano, Hawaii: Insights from ash characterization and geochemistry
Several powerful explosive eruptions have taken place in the populated lower East Rift Zone of Kīlauea within the past ∼750 years. These have created distinctive landforms, including a tephra rim enclosing Puʻulena Crater immediately south of the Puna Geothermal Venture power station, a tuff cone at Kapoho Crater near the eastern cape of the Island of Hawaiʻi, and a set of littoral cones...

Climate-influenced phenology of larval fish transport in a large lake Climate-influenced phenology of larval fish transport in a large lake
Elucidating physical transport phenologies in large lakes can aid understanding of larval recruitment dynamics. Here, we integrate a series of climate, hydrodynamic, biogeochemical, and Lagrangian particle dispersion models to: (1) simulate hatch and transport of fish larvae throughout an illustrative large lake, (2) evaluate patterns of historic and potential future climate-induced...

Bird community response to one decade of riparian restoration along the Colorado River delta in Mexico Bird community response to one decade of riparian restoration along the Colorado River delta in Mexico
We assessed the response of breeding birds to one decade of riparian restoration in the Colorado River delta including active vegetation management since 2010 and various environmental water deliveries since 2014. Bird surveys were conducted from 2002 to 2021 at 230 bird count stations distributed along five river reaches with different hydrogeomorphic characteristics, across 7 routes in...
