Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Assessing crop's responses to elevated carbon dioxide (eCO2) is crucial for global food security. This study examines the impact of eCO2 (700 μmol mol−1) on the cultivars of lentil (Lens culinaris), local Pardina Verde Rayada lentil (PVRL), and commercial Pardina lentil (PL) in terms of the productivity and nutritional composition ...

Seed production, infestation, and viability in Acacia tortilis (synonym: Vachellia tortilis) and Acacia robusta (synonym: Vachellia robusta) across the Serengeti rainfall gradient [PDF]
, 2017 Tree recruitment in savannas proceeds in multiple stages characterized by successive filters occurring at the seed and seedling stages. The “demographic bottleneck” hypothesis suggests that such filters ultimately restrict tree density and prevent trees ...

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Water scarcity and soil salinization are major constraints to irrigated agriculture in semi‐arid regions, affecting crop productivity and fruit quality. Combining deficit irrigation with biostimulant application has emerged as a promising strategy to improve water use efficiency and plant stress tolerance.

Comparing autumn duck use of intensely managed wetlands in Michigan using a novel approach
The Journal of Wildlife Management, EarlyView.Camera traps, a relatively novel method for assessing waterfowl use of wetlands, show ducks in southeastern Michigan are influenced by hunting disturbance, vegetation type, season progression, and diel period. Abstract Socioeconomic value derived from duck hunting has contributed to autumn habitat use becoming a particular focus for the natural ...

Density‐dependent habitat selection in plains bison
The Journal of Wildlife Management, EarlyView.Using GPS collar data, we tested whether habitat selection of plains bison in Grasslands National Park, Canada, was density dependent. Bison selected for areas of high vegetation productivity far from human activity when population density was low and increased use of lower productivity habitat closer to disturbance as density increased.

Limnology and Oceanography: Methods, EarlyView.Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...
