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.

Abstract Global warming is now predicted to exceed 1.5°C by 2033 and 2°C the end of 21st century. This level associated environmental variability are already increasing pressure on natural human systems. Here we emphasize role physiology in light latest assessment climate Intergovernmental Panel Climate Change. We describe how can contribute contemporary conservation programmes. focus thermal responses animals, but acknowledge that impacts change much broader phylogenetically environmentally. A physiological contribution would encompass monitoring, coupled with measuring individual sensitivities temperature upscaling these ecosystem level.

The scaled sardine’s unique metabolic phenotype and its implications for the susceptibility of small tropical pelagic fishes to climate change

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Апрель 25, 2025

Small pelagic fishes (e.g., sardines, anchovies and their relatives) are preyed upon by large predatory fishes, birds mammals, thus, key species in marine food webs with respect to ecosystem health productivity. However, we know little about physiology, such information will be critical predicting how populations may impacted human-induced rapid environmental change (HIREC) implementing effective conservation strategies. As a first step, determined the maximum swimming speed, aerobic capacity [maximum metabolic rate (MMR) scope (AS)] cost of transport (COT; energy required swim given distance) scaled sardines (Harengula jaguana) collected Eleuthera (The Bahamas). The sardine's speed (Ucrit) was ~ 5-6 body length's per second, this agrees data on free-swimming schools similar wild. they had unexpectedly high values for MMR AS (~ 25% 70% greater than tuna, respectively), COT. These findings have important implications regard these ecologically potentially respond HIREC-related challenges as increased temperature decreases biomass size plankton which feed.

Cortisol in fish scales remains stable during extended periods of storage

Measurement of cortisol in fish scales is attracting considerable attention as a non-invasive indicator chronic stress wild populations. For many species management and conservation interest, extensive scale collections exist that could provide extended records individual responses, by combining measurements with life history information. However, it not yet known how well preserved the during storage. To investigate stability cortisol, we accelerated potential degradation storing from an farmed Atlantic salmon (

Applied winter biology: threats, conservation and management of biological resources during winter in cold climate regions

Conservation Physiology, Год журнала: 2023, Номер 11(1)

Опубликована: Янв. 1, 2023

Abstract Winter at high latitudes is characterized by low temperatures, dampened light levels and short photoperiods which shape ecological evolutionary outcomes from cells to populations ecosystems. Advances in our understanding of winter biological processes (spanning physiology, behaviour ecology) highlight that biodiversity threats (e.g. climate change driven shifts reproductive windows) may interact with conditions, leading greater impacts. As such, conservation management strategies consider their consequences on mechanisms lead resilience altitude latitude Here, we use well-established threat action taxonomies produced the International Union Conservation Nature—Conservation Measures Partnership (IUCN-CMP) synthesize current biota emerge during, or as result of, then discuss targeted approaches for winter-based conservation. We demonstrate importance considering when identifying deciding appropriate across species confirm expectation are prevalent during especially important physiologically challenging conditions presents. Moreover, findings emphasize winter-related constraints organisms will intersect other stressors potentially magnify further complicate management. Though practices less commonly considered season, identified several potential already realized applications relevant could be beneficial.

Learning, thinking, sharing, and working across boundaries in fisheries science

ICES Journal of Marine Science, Год журнала: 2024, Номер 81(4), С. 665 - 675

Опубликована: Март 20, 2024

Abstract Fisheries science and practice are challenging require learning, thinking, sharing across boundaries. The idea of boundary crossing can be described as some form multiple disciplinarity (e.g. interdisciplinarity, transdisciplinarity), yet that inherently implies the boundaries crossed purely disciplinary in nature. After working various other (i.e. realms, regions, disciplines, sectors, domains, knowledge systems) for most our educational journeys professional careers, we reflect on lived experiences with a focus identifying benefits challenges engaging different types crossing. We submit personal lives have been enriched by stepping outside immediate comfort zones expertise fish ecology) active listening learning colleagues disciplines social sciences) stakeholders policymakers. learned much from encourage others, especially early career professionals, to do same. What may superficially appear bridge too far fact provide novel ways thinking about given issue or topic generates actionable sustainable fisheries management conservation.

El gobierno mexicano creó la figura de Unidades Manejo para Conservación Vida Silvestre (UMA) con el fin proteger y aprovechar manera sustentable las especies mexicanas. Su funcionamiento se ha evaluado históricamente indicadores meramente administrativos. objetivo esta investigación es analizar tipo manejo que promueven dichas unidades a nivel nacional impacto generan en conservación biológica. Para ello, utilizaron dos enfoques: uno diacrónico mediante tendencias mapas coropléticos desarrollo histórico UMA 1999 2021, otro sincrónico través del cual generaron índices biológica durante 2018. Los resultados muestran una tendencia decreciente número superficies incorporadas. indican más son aplican un dirigido estabilizar poblaciones vida silvestre obtener cosechas sostenidas. Las presentan siguientes problemáticas: 1) cubren muy poca superficie forestal cada entidad, 2) han centrado grupo reducido especies, 3) alguna categoría riesgo limitado, 4) existen están promoviendo introducción exóticas.

Seabirds and climate change in North‐West Europe: Identifying opportunities for an effective and efficient conservation response

Conservation Science and Practice, Год журнала: 2024, Номер 6(10)

Опубликована: Сен. 3, 2024

Abstract Climate change poses a massive and growing threat to wildlife. Calls are for coordinated collaborative responses conserve species threatened by climate change, but how this works in practice remains largely unexplored. Focusing on seabirds North‐West Europe, we carried out 32 semi‐structured stakeholder interviews (1) explore existing conservation work linked (2) identify barriers among actors, (3) key actors characterize their interactions. Interviewees identified range of research, policy, practical related—directly or indirectly—to change. They highlighted the importance general facilitate seabird adaptation global mitigation (e.g., through decarbonization ecosystem restoration). several explicitly addressing pertaining information, leadership, resources, values/beliefs. We discovered that networks generally well‐established harmonious, not tension‐free. There also some misunderstandings over actor responsibilities could lead bystander effects. present suggestions increase effectiveness efficiency response
