Nutritional and reproductive dynamics of moose near their southern range limit

open access: yesThe Journal of Wildlife Management, EarlyView.
Though southern moose (Alces alces) had relatively low seasonal fluctuations in body fat, their condition was positively associated with pregnancy and adult survival but did not influence recruitment of young. We demonstrated clear signs of nutritional limitation and unexpected patterns of reproductive performance that may be unique to moose living at ...

Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...

Coupling Water Purification and Carbon Sequestration at Various Spatial Scales From Supply and Demand Perspective

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Balancing ecosystem‐service supply and demand is central to understanding both the natural and social dimensions of ecosystem services and to enhancing human well‐beings. Concurrently, collaborative efforts are underway to improve multiple ecosystem services, including the promotion of carbon neutrality and water purification (WP) within basin

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

open access: yesLimnology 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 ...

Distribution under climate change of Anemone coronaria: linking flower colour and seed dispersal

open access: yesNordic Journal of Botany, EarlyView.
Flower colour polymorphism is driven by divergent selection regimes on the colour morphs across time and space. Anemone coronaria, a colour‐polymorphic geophyte with red, purple, and white flowers, displays a geographic pattern along Israel's aridity gradient: polymorphic populations are restricted to Mediterranean climates, while monomorphic‐red ...
