Tropicalization of the Temperate Zone: Spatiotemporal Variability of Winter Warming and Declining Freeze Days Across the United States

International Journal of Climatology, EarlyView.
Unique characteristics of winter daily minimum (Tmin) and maximum (Tmax) temperatures and freeze days across the conterminous United States from 1952 to 2024 are examined. Results show spatial heterogeneity in Tmin/Tmax warming rates across the tropical‐temperate transition zone in the southeastern United States, and that the highest temperature on the

The dual role of detritus as resource and habitat: integrating non‐trophic processes to ecosystem dynamics

Oikos, EarlyView.
The diversity of ecological interactions, both trophic and non‐trophic, is central to understanding the assembly of communities. However, we have yet to study non‐trophic processes through their action on ecosystem compartments such as detritus involved in both recycling and habitat provisioning.

Better Alone Than in Bad Company: Trophic Ecology of Co‐Occurring Invasive and Native Crayfish

Ecology and Evolution
The North American signal crayfish, Pacifastacus leniusculus, is one of the most successful invasive crayfish species in Europe. Its broad trophic niche and ability to exploit various food sources across different trophic levels, coupled with the spread ...

The impact of signal crayfish (Pacifastacus leniusculus) on the recruitment of salmonid fish in a headwater stream in Yorkshire, England [PDF]

Knowledge and Management of Aquatic Ecosystems, 2009
Signal crayfish (Pacifastacus leniusculus) have become increasingly widespread in rivers in Great Britain since their introduction in the late 1970s, causing extensive losses of indigenous white-clawed crayfish and negative impacts on communities of ...

A Multi‐Method Approach to Assessing Barrier Effectiveness in Preventing the Spread of Invasive Signal Crayfish (Pacifastacus leniusculus)

River Research and Applications, EarlyView.
ABSTRACT Relieving barriers and increasing free flowing rivers is a global imperative to restore habitat connectivity for migratory fish stocks. While reducing river fragmentation will certainly improve biodiversity, the spread of non‐native species throughout a river system may be facilitated as an inadvertent outcome.

Dietary differentiation of two co‐occurring common bat species (Eptesicus nilssonii and Pipistrellus pygmaeus)

Wildlife Biology, EarlyView.
Sympatric bat species can co‐exist and avoid interspecific competition via niche differentiation e.g. diet. Detecting dietary differences can be achieved by comparing dietary niches of sympatric and allopatric populations. If dietary overlap is higher in sympatry versus allopatry, co‐occurrence may be altering the dietary niche of the species.

Effects of dietary myo-inositol on growth performance, hematological parameters, antioxidant capacity, immunity and resistance against Aeromonas hydrophila in red swamp crayfish (Procambarus clarkii)

Aquaculture Reports
The red swamp crayfish (Procambarus clarkii) is of importance in the crustacean farming of China. Myo-inositol (MI) as a vitamin-like nutrient has not been investigated in P.

Using eDNA to detect the distribution and density of invasive crayfish in the Honghe-Hani rice terrace World Heritage site.

PLoS ONE, 2017
The Honghe-Hani landscape in China is a UNESCO World Natural Heritage site due to the beauty of its thousands of rice terraces, but these structures are in danger from the invasive crayfish Procambarus clarkii.

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

Journal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...
