Ecology of overwintering sprat (Sprattus sprattus) [PDF]
, 2015 We used moored upward-facing echosounders in combination with field campaigns to address the overwintering ecology of the clupeid sprat (Sprattus sprattus) throughout four separate winters in a Norwegian fjord.

Virus species affecting the health of overwintering honey bee (Apis mellifera ligustica) colonies
浙江大学学报. 农业与生命科学版, 2018 To identify virus/viruses associated with the health of overwintering honey bee colonies, we investigated the viral infection status of 48 Apis mellifera ligustica colonies in three apiaries before and after overwintering.

Modeling of the overwintering distribution of Puccinia striiformis f. sp. tritici based on meteorological data from 2001 to 2012 in China [PDF]
Frontiers of Agricultural Science and Engineering, 2014 Wheat stripe rust caused by Puccinia striiformis f. sp. tritici occurs widely in China and seriously affects wheat production. Global warming could profoundly impact the incidence and prevalence of low-temperature diseases such as stripe rust. Studies on

Autumn shifts in cold tolerance metabolites in overwintering adult mountain pine beetles [PDF]
, 2020 The mountain pine beetle, Dendroctonus ponderosae (Coleoptera: Curculionidae) is a major forest pest of pines in western North America. Beetles typically undergo a one-year life cycle with larval cold hardening in preparation for overwintering.

Ecography, EarlyView.Predator–prey interactions are vital to ecosystem functioning but may be disrupted by climate change. We investigated a food‐web network involving three owl species over 24 years in a semi‐arid ecosystem at Bosque Fray Jorge National Park, Chile.

Microclimate mediates the strength and direction of avian biotic interactions
Ecography, EarlyView.Theory predicts that the strength and direction of species interactions can shift from being competitive in benign environments toward being facilitative in stressful environments. However, the environmental context dependency of species interactions has rarely been tested in animal communities.

Ecography, EarlyView.As extreme climatic events are becoming more frequent, we need to understand what mechanisms could buffer populations to ensure their persistence. Fragmented populations may be especially vulnerable, as exemplified by species with metapopulation dynamics whose persistence is determined by a precarious balance between frequent local extinctions and ...

Ecography, EarlyView.Predator–prey interactions can trigger behavioural responses in ungulates, influencing their space‐use and foraging behaviour and, in turn, indirectly affecting browsing pressure. Changes in browsing pressure can affect plant recruitment and species composition, shaping forest regeneration through predator‐mediated trophic cascades.

Grassland Research, EarlyView.Abstract Background Leaf shatter during low‐moisture baling and mold proliferation under high‐moisture conditions pose major challenges in alfalfa hay production. A proprietary propionic acid‐based hay preservative product, LZP, effectively inhibits microbial reproduction in high‐moisture alfalfa bales; however, its optimal moisture thresholds and ...
