Shifting stage‐specific constraints on productivity shape recovery potential for Yukon River Chinook salmon

open access: yesEcological Applications, Volume 36, Issue 3, April 2026.
Abstract Identifying key life history periods in which population productivity is constrained represents a persistent challenge in conservation and natural resource management. For species with complex life cycles, such as Pacific salmon (Oncorhynchus spp.), population dynamics may be shaped by interactions between natural and anthropogenic impacts ...

Predicting adult mosquito (Culex pipiens) emergence in response to temperature, nutrients, and salinity

open access: yesEcosphere, Volume 17, Issue 4, April 2026.
Abstract While human activities lead to unprecedented declines in biodiversity, mosquitoes tend to thrive in human‐disrupted environments. A high mosquito abundance is a clear risk for the transmission of vector‐borne diseases, and understanding how environmental factors influence mosquito development is crucial for better predicting their abundance ...

Climate‐Driven Advanced Machine Learning Approach for Dengue Incidence Forecasting in Bangladesh

open access: yesHealth Science Reports, Volume 9, Issue 4, April 2026.
ABSTRACT Background and Aims Dengue fever has become a significant and an increasing public health menace in Bangladesh. Despite the abundance of research on the dengue outbreaks, the majority of the studies are limited by the short‐term time frame of research, a narrow scope, or to one modeling methodology.

Lactation Persistency in Spring‐Calving Grazing Dairy Cows During Extended Lactation

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
Lactation persistency, or the ability of a cow to maintain high milk yield throughout lactation, is important for extended lactation (EL: beyond 305 days in milk). Persistency is a characteristic that could support the identification of cows suitable for EL. This study evaluated the factors that affect lactation persistency during EL in grazing, spring
