Biology, ecology, and conservation of the Italian hare Lepus corsicanus: a review

open access: yesWildlife Biology, EarlyView.
The Italian hare Lepus corsicanus, an endemic lagomorph of Italy, serves as a critical case study in evolutionary biology and conservation. Once taxonomically debated, modern genetic and morphological analyses confirm its status as a distinct Pleistocene lineage restricted to the central‐southern Italian Peninsula and Sicily.

Local Scour at the Elliptical Guide Banks

open access: yes
Scour development in time at the elliptical guide banks during the floods was studied. The dimensions of the upper part of the elliptical guide banks, namely the turn and length, were calculated by the Latishenko method.

Estimation of Local Scour Dimension below Siphon Spillway with the Ski-jump Bucket Energy Dissipater Using the Group Method of Data Handling (GMDH)

open access: yesعلوم آب و خاک, 2018
The investigation of local scour below hydraulic structures is so complex that makes it difficult to establish a general model to provide an accurate estimation for the local scour dimension.

Context‐Dependent Effects of Beavers (Castor spp.) on Freshwater Pearl Mussels (Margaritifera margaritifera) in European Rivers 河狸对欧洲河流中的淡水珍珠贝 (Margaritifera margaritifera) 存在情境依赖性影响

open access: yesWildlife Letters, EarlyView.
The study explores how beavers (Castor spp.) affect endangered freshwater pearl mussels (Margaritifera margaritifera) in European rivers. Beaver dams can harm small, fragmented mussel populations by reducing flow, increasing sediment, and potentially limiting host fish movement, while larger populations may benefit from improved bed stability and ...

Assessing the Influence of Interference Competition on Ecologically Similar Species Threatened by Habitat Loss 评估干扰性竞争对受栖息地丧失威胁的生态相似物种的影响

open access: yesWildlife Letters, EarlyView.
We staged dyadic interaction trials between two kangaroo rat species threatened by habitat loss to test whether one species dominates in direct interactions in the field. We found that Stephens’ kangaroo rat (Dipodomys stephensi) residents and intruders were dominant over Dulzura kangaroo rat (Dipodomys simulans). These results suggest that D. simulans

Urban oases relax desiccation risk for an arid‐adapted lizard

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Urbanization from expanding human development has radically altered the structure, ecology and microclimate of landscapes worldwide. These dramatic environmental alterations subject organisms to novel ecological conditions and may select for distinct ecophysiological ...

Foraging energetics reveals late‐summer challenges for pollinators across two British cities

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Foraging bees often work within fine energetic margins, but recent work has shown that foraging conditions can vary markedly across the year. Despite the importance of seasonality for pollinator foraging, most work in this area has relied on indirect approaches. However,

Flow and likely scour around three dimensional seabed structures evaluated using RANS CFD

open access: yes, 2007
When a structure is placed on the seabed, tidal or other marine current induce areas of flow acceleration and deceleration. This may result in movement of the seabed substrate (often sand) near the structure.

Resilience in the heights: Elevational filtering preserves taxonomic and functional beta diversity over time against biotic homogenization

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental heterogeneity generates taxonomic and functional beta diversity, but a key question regards whether heterogeneity can maintain functional diversity when global change causes range shifts, potentially causing biotic homogenization by favouring species ...

Herbivore and mesocarnivore carcasses trigger divergent short‐term changes in soil properties

open access: yesJournal of Animal Ecology, EarlyView.
Scavengers reshape nutrient cycles in soils under carrion. Compared to herbivore carcasses, smaller but longer‐lasting carnivore remains boost nutrient levels and microbial activity in dry soils. Abstract Animal corpses act as pulses of organic matter (OM) and serve a key zoogeochemical role by providing localized nutrient inputs to soils and thereby ...
