Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

Animal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.

Epizootic Activity of Natural Foci of Tularemia in Three Territories of the Arctic Zone

Epidemiology and Vaccinal Prevention
Relevance. Tundra natural foci of tularemia are epizootically active. They are supported mainly by populations of endemics – ungulate and Siberian lemmings. However, studies of natural foci of tularemia in the Arctic zone were and are irregular. Recently, in connection with the intensification of economic development of the Far North, the study of the ...

Nonhuman Mobilities and Multispecies Border Regimes in (Post‐)Colonial Southern Africa**

Berichte zur Wissenschaftsgeschichte, EarlyView.
This article explores how borders in Southern Africa—such as Namibia's internal veterinary and settler border (Red Line) and national borders between Namibia, South Africa, and Botswana—functioned not only as territorial dividers but as tools to shape colonial and postcolonial multispecies hierarchies. These borders regulated human and animal movement,

Nonstationarity in wildlife disease dynamics: insights from the prairie dog–plague system

Oikos, EarlyView.
Ecological relationships often vary in strength and direction across ecosystems, a pattern that has become increasingly evident as ecology expands to broader spatial and temporal scales. Although such nonstationarity – the changing effect of predictor variables across spatiotemporal contexts – is widely acknowledged in ecological research, it has ...

Evaluating larvicide performance against Culicoides sonorensis in semi‐field conditions

Pest Management Science, EarlyView.
This study evaluated the efficacy of larvicide products against Culicoides sonorensis populations under controlled semi‐field conditions. Larvicide efficacy against C. sonorensis declined over time, in different environmental conditions. In particular, precipitation and habitat disturbance influenced residual performance. Abstract BACKGROUND Culicoides

Extreme weather and economic crisis in the 1430s in England, and the implications for tenurial change

The Economic History Review, EarlyView.
Abstract The 1430s were characterized by extreme weather conditions, food and fodder shortages, and high mortalities among animals and humans, although the severity of events and their consequences in England have received limited attention. The economic downturn and the depressed customary land market in this decade marked the beginning of the Great ...

A CRISPR‐Based Rapid Detection Assay for Crayfish Plague (Aphanomyces astaci) From Environmental Samples

Journal of Fish Diseases, EarlyView.
ABSTRACT Crayfish plague, caused by Aphanomyces astaci (Aa), is an infectious disease invasive in Europe, where its rapid spread has resulted in sharp declines of native crayfish species. Monitoring currently relies on a highly sensitive, but costly and time‐consuming qPCR approach.
