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.

Investigations of Structural-Functional Aspects of Epizootic Process in Natural Plague Foci in Siberia [PDF]

, 2013
Comprehensively studied have been structural elements of ecosystems of Siberian natural plague foci, as well as levels of integration among epizootic process components, and ways of their functional interaction. Application of the complex approach to 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 ...

The role of specific prophylaxis in the control of the epizootic process of brucellosis in small ruminants

Veterinaria i kormlenie, 2022
A retrospective epizootic analysis proves the effectiveness of control of the epizootic process of brucellosis in small ruminants in large public farms with the annual use of live agglutinogenic vaccine from the B. abortus 19 strain (with thesubcutaneous injection method) in dysfunctional and threatened brood flocks.
