The costs of extra‐pair behaviours in birds

open access: yesBiological Reviews, EarlyView.
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Drones, automatic counting tools, and artificial neural networks in wildlife population censusing

open access: yesEcology and Evolution, 2021
The use of a drone to count the flock sizes of 33 species of waterbirds during the breeding and non‐breeding periods was investigated. In 96% of 343 cases, drone counting was successful.

Invertebrate dispersal by waterbird species in neotropical wetlands

open access: yesBrazilian Journal of Biology, 2021
Endozoochory by waterbirds is particularly relevant to the dispersal of non-flying aquatic invertebrates. This ecological function exercised by birds has been demonstrated in different biogeographical regions, but there are no studies for the neotropical

Green swans and blue skies: Climate change and insolvency risk for financial institutions

open access: yesInternational Insolvency Review, EarlyView.
Abstract This lecture in honour of the late Gabriel Moss QC and Ian Fletcher QC examines the challenge of climate‐related financial risk. Prudential regulators and central banks recognize that the systemic nature of climate‐related financial risk makes it an emerging vulnerability relevant to cross‐border insolvency resolution.

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

open access: yesOikos, EarlyView.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...

Shallow sub-lakes are essential for sustaining the successful wintering of waterbirds in Poyang Lake, China

open access: yesAvian Research
For migratory waterbirds, the quality of wintering habitat is related to spring migration and successful breeding in the next year. The availability of food resources in the habitat is critical and varies within water levels.

A Functional Flows Framework for the Terminal Great Salt Lake Basin: Can We Have Our Lake and Drink It Too?

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Terminal basins provide unique aquatic environments that are often highly sensitive to streamflow contributions, making them a focal point for environmental water management. However, the water needs for terminal lake, wetland, and river ecosystems, and how they relate, remain a fundamental knowledge gap that constrains our ability to ...
