ABSTRACT Aim Identifying habitats vulnerable to plant invasions is essential for developing efficient management programmes. We assessed trends in richness and cover of non‐native plants indigenous shrublands forests across New Zealand. investigated whether species classed as invasive exhibited higher levels invasion than naturalised the extent which this reflected life form. Location Time Period From January 2009 March 2014. Major Taxa Studied Plant. Methods analysed 839 permanent 20 × m plots spread Zealand that could be classified a recognised forest type: mānuka‐kānuka shrubland, beech, beech‐broadleaved, beech‐broadleaved‐podocarp broadleaved‐podocarp forests. Generalised additive models were run with native canopy or spatial coordinates co‐variables order compare types relation their status growth Results Overall, 35% had at least one species. Mānuka‐kānuka shrubland highest mean (11 species) (32%) presenting next level but much lesser (1.7 3% cover). Despite overall greater richness, lower (4.2%, 13.5%, respectively). This pattern was mainly related woody that, despite low can reach herbaceous once established. Main Conclusions half flora being composed species, relatively few found habitats. However, early successional showed vulnerability invasion. Woody are overrepresented among less limited by cover. Such findings highlight threat posed need more targeted

High densities of managed honey bees (Apis mellifera) can threaten wild through exploitative competition, thus leading to population declines. Although reviews have outlined key steps demonstrate these impacts—measuring resource overlap, changes in bee behaviour, and trends—studies that comprehensively address aspects are virtually absent. We were granted access the entire protected island Giannutri (2.6 km2) apiary (18 hives) located there, during early phase co-existence between bees. Using as an open-air laboratory, we experimentally manipulated pressure by closing hives on selected days peak foraging period. In plants most visited pollinators even short-term removals (11 hours per day) increased nectar volume (~60%) pollen availability (~30%). absence bees, target (Anthophora dispar Bombus terrestris) became dominant insect-plant visitation network potential apparent competition significantly decreased. Accordingly, both species intensified their activity suction time, a recognised proxy for quantity probed nectar, B. terrestris also shortened time searching. Transect monitoring revealed alarming ~80% decline over four years, consistent with monopolisation floral resources, reducing altering budget. These findings underscore risks introducing high into areas emphasise need rigorous preventive ecological assessments.

Pale terricolous lichens are a vital component of Arctic ecosystems, significantly contributing to carbon balance, energy regulation, and serving as primary food source for reindeer. Their characteristically high albedo also impacts land surface temperature (LST) dynamics across various spatial scales. However, remote sensing is challenging due their complex spectral signatures large variations in coverage biomass even within local landscape This study evaluates the influence pale on LST at scales by integrating RGB, multispectral, thermal infrared imagery from an Unmanned Aerial Vehicle (UAV) with multi-temporal Landsat 8 data. An Extreme Gradient Boosting algorithm was employed map lichen biomass, areal extent, occurrence major plant functional types sub-arctic heath tundra Jávrrešduottar Sieiddečearru areas Finland-Norway border. Generalized Additive Models (GAMs) were used elucidate factors affecting LST. The UAV model accurately predicted (R2 0.63) vascular vegetation cover 0.70). GAMs revealed that regimes, increased leading decreased LST, effect more pronounced scale (deviance explained 47.26 % 65.8 models, respectively). identified second most important variable both scales, elevation being variable. research demonstrates capability UAV-derived models capture heterogeneous fine-scale structure ecosystems. Furthermore, it underscores effectiveness combining resolution temporal satellite platforms. Finally, this highlights pivotal role showcases how advanced techniques can be ecological monitoring management.

ABSTRACT Human activities have profound impacts on ecological systems and biodiversity worldwide. Estimating wildlife response to those across broad spatial scales is challenging, yet effective conservation measures require an understanding of where when these are contributing population declines. We investigated the relationship between exposure human (conservation challenges) trends migratory warblers (Parulidae) that breed in United States Canada. Our four‐stage approach (1) summarizes literature describing sensitivity species challenges; (2) estimates weekly species' full annual cycle; (3) quantifies correlations among (4) relationships seasonal challenges warbler trends. Exposure during post‐breeding migration, followed by stationary non‐breeding season pre‐breeding explained most variation Within season, with greatest total values were roads, light pollution, communication towers, forest management, livestock management. During this undergoing steepest declines associated urban suburban areas, agriculture. Notably, breeding was not important predictor results provide hemispheric, cycle information for prioritizing investments additional research warblers, specifically importance addressing which birds exposed migration. More broadly, framework can be used assess spatiotemporal impacting globally.
