ABSTRACT Animal migration has fascinated scientists and the public alike for centuries, yet migratory animals are facing diverse threats that could lead to their demise. The Anthropocene is characterised by reality humans dominant force on Earth, having manifold negative effects biodiversity ecosystem function. Considerable research focus been given assessing anthropogenic impacts numerical abundance of species/populations, whereas relatively less attention devoted animal migration. However, there clear linkages, example, where human‐driven behaviour can population/species declines or even extinction. Here, we explore (in all domains – aquatic, terrestrial, aerial) using International Union Conservation Nature (IUCN) Threat Taxonomy classifications. We reveal (e.g. human development, disease, invasive species, climate change, exploitation, pollution) impact wildlife in varied ways spanning taxa, life stages type from direct mortality changes behaviour, health, physiology). Notably, these often interact complex unpredictable detriment wildlife, further complicating management. Fortunately, beginning identify strategies conserving managing Anthropocene. provide a set that, if embraced, have potential ensure animals, important ecological functions sustained migration, persist.

Predicting resilience of migratory birds to environmental change

Proceedings of the National Academy of Sciences, Journal Year: 2024, Volume and Issue: 121(19)

Published: April 22, 2024

The pace and scale of environmental change represent major challenges to many organisms. Animals that move long distances, such as migratory birds, are especially vulnerable since they need chains intact habitat along their routes. Estimating the resilience species changes assists in targeting conservation efforts. We developed a migration modeling framework predict past (1960s), present (2010s), future (2060s) optimal strategies across five shorebird (Scolopacidae) within East Asian-Australasian Flyway, which has seen deterioration loss over last century, compared these predictions empirical tracks from present. Our model captured identified migrations needed respond climate change. Notably, larger species, with single or few stopover sites, establish new routes strategies, while smaller can buffer by redistributing areas novel less-used sites. Comparing also indicates stronger for adaptations continue migrate closer past, before accelerated. study not only quantifies vulnerability face global but explicitly reveals extent required sustain migrations. This provides tool planning accommodate needs species.

Migration strategy and constraint in migration behavior vary among shorebird species with different life histories

Ecosphere, Journal Year: 2025, Volume and Issue: 16(1)

Abstract Migration strategy is a key behavioral characteristic guiding how migratory species time their annual cycles and use habitat. Understanding variation in migration within among individuals can be useful for understanding birds navigate energetic trade‐offs designing or modifying conservation plans meant to benefit multiple life histories. We compared strategies three shorebird with variable history traits short, medium, long distances, respectively: American avocets ( Recurvirostra americana ), black‐bellied plovers Pluvialis squatarola Hudsonian godwits Limosa haemastica ). Avocets (short distance) exhibited the most within‐species duration, proportion of spent at stopovers, stopover duration. Plovers (medium (long showed less these metrics, but number stopovers used. There were significant differences distance, used, stopped over, departure arrival dates, not mean also found that more over relative distance than godwits, indicating energy‐minimizing species. Our findings set stage future work assessing effects climate change land on characteristics associated different additional
