This study examines the impact of climate change on altitudinal movement patterns and number individuals four large mammal species within Central Alborz Protected Area (CAPA) region Mountains, a biodiversity hotspot, over 23-year period (1999 to 2022). During warm season (May 25-September 29), temperatures were reported have increased by 2-2.5 °C, while relative humidity was observed decreased 4-4.5%. Compared past two decades (2000-2022), Caspian red deer initiate their annual high-altitude migrations 15-20 days earlier, with in summer range increasing more than threefold. Wild goats also migrated peak arrivals from 20-36 (1999-2003) 36-57 (2018-2022) between May 25 31, highlighting temperature as primary driver herbivore movement. In contrast, brown bears exhibited subtle movement, likely influenced both humidity. boars, an approximate 40% increase individuals, tended return lower elevations earlier previous years (1999-2003). These highlight role significant regulator ecology, influencing habitat use. However, human-induced barriers, such roads settlements, present additional threats these seasonal migrations. underscores urgent need for adaptive management strategies, including protection corridors, expansion core zones, enhanced community engagement, support resilience under changing climatic conditions.

ABSTRACT The role of pathogens in impacting the behaviour and fate salmonids has been studied extensively for some selected such as sea lice. However, whole pathobiome fish are seldom considered may confound influence study species situ. In this study, we investigated presence returning adult wild hatchery salmon river Vosso using gill samples analysed high‐throughput PCR with a selection assays targeting different pathogens. addition, were gene expressions that have previously linked to imminent mortality, thermal stress, inflammation related biomarkers. These data individual collected from acoustic telemetry tags inserted abdomen fish. Previous analyses suggested area is different; however, there was no evidence or expression two groups (39 14 hatchery) could explain behavioural differences between these groups. Furthermore, neither pathogen profile nor had significant relationship metrics survival Results suggest screenings insufficient predict fates migrating salmon. threatened population Norway after collapsing 1980s; contribute ongoing efforts identify factors limiting recovery decades poor returns.

Human activity in the North Sea is intensifying, as emerging uses, such offshore wind farms (OWFs) and liquid natural gas (LNG) terminals, are added to fishing, freight shipping fossil fuel production traditional forms of resource exploitation. The volume scale these additional installations projected increase substantially coming decades, which amplifies need understand better biological implications human activities ecoregion. Previous studies have identified that turbines either pose a physical barrier flying animals, leading avoidance displacements, or act sensory traps attracting animals by interfering with input cues, increased collision risk mortality. Here we aim characterise impacts artificial light pollution at night (ALAN) on migratory birds bats, discuss for conservation policy practice. Considering littoral states aiming multiply OWF capacity factor eight before year 2050, significant cumulative ALAN can be expected. In developments, potential scientifically informed, anticipatory ecosystem-based marine governance.

ABSTRACT Although decades of research have deepened our understanding the proximate triggers and ultimate drivers migrations for a range taxa, how populations establish remains mystery. However, recent studies begun to illuminate interplay between genetically inherited learned migrations, opening door evaluation migration may be learned, established, maintained. Nevertheless, migratory species where role learning is evident, we lack comprehensive framework learn specific routes refine movements over time (i.e., their origins). This review draws on advances in behavioural movement ecology offer could transition from resident by connecting cognitive fine‐scale perceptual cues decisions with literature cultural transmission, emergent pattern migration. We synthesize multiple mechanisms processes that allow population respond seasonal resource limitation, then encode spatial environmental information about availability memory engage social navigate landscapes track resources better. A rise global reintroduction efforts, along human‐induced rapid shifts changing make evaluating origins this threatened behaviour more urgent than ever.

Abstract Effective conservation of migratory species relies on habitat protection throughout their annual cycle. Although protected areas (PAs) play a central role in conservation, effectiveness at conserving habitats across the cycle has rarely been assessed. We developed seasonal ecological niche models for 418 butterfly global distribution to assess whether they were adequately represented PAs full PA coverage was inadequate least one season 84% butterflies, adequate only 17% season, and 45% all seasons. There marked geographic variation coverage: 77% met representation targets Sri Lanka, example, but 32% Italy. Our results suggest that coordinated efforts multiple countries will be needed develop international networks cover insects measures, addition establishment maintenance PAs, are likely effectively conserve these species.
