Forage mass and botanical composition of four annual forages grown in a loblolly pine silvopasture in the Mid‐South USA

open access: yesCrop, Forage & Turfgrass Management
Abstract Annual forages are commonly planted in open pasture in the Mid‐South, but there is little information on the productivity of these forages when incorporated into silvopasture. The objective was to evaluate four annual forages adapted to the Mid‐South, namely, arrowleaf clover ...

Consumer diversity drives stronger predation in tropical marine communities

open access: yesEcography, EarlyView.
Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Flight speed and body mass of nectar-feeding bats (Glossophaginae) during foraging

open access: yesJournal of Experimental Biology, 1999
ABSTRACT Aerodynamic theory predicts that minimum power (Vmp) and maximum range (Vmr) flight speeds increase when the body mass of an individual animal increases. To evaluate whether foraging bats regulate their flight speed within a fixed speed category relative to Vmp or Vmr, I investigated how the natural daily changes in body mass ...

Relationship between home range and population density in mammals: the role of sociality, territoriality and habitat dimensionality

open access: yesEcography, EarlyView.
Organisms' energy requirements increase with body mass, leading to larger home range areas and lower population density. Previous research has highlighted the differential scaling of these variables in mammals, where species with large home ranges have higher density than expected due to increased home range overlap. Here we investigate this phenomenon

Macroecological relationships of ant diversity with increasing aridity in Australian tropical savannas: contrasting responses of epigaeic and hypogaeic assemblages

open access: yesEcography, EarlyView.
Studies using climatic gradients play a key role in our understanding of the importance of rainfall and temperature as factors regulating species diversity and distribution, and thus of likely responses to climate change. However, such studies currently consider above‐ground species only, ignoring the diverse hypogaeic (subterranean) invertebrate fauna.

Comparative Assessment and Benchmarking of Metaheuristic Algorithms for Dynamic Photovoltaic Array Reconfiguration Under Diverse Shading Environments

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...

Vaginal host–microbe signatures linked to placental outcomes in mares

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Ascending placentitis is a leading cause of late‐term pregnancy loss in mares. Although pathogens are presumed to ascend from the caudal reproductive tract, the association between the vaginal microbiome and placentitis has not been systematically examined.

Oscillometric assessment of bronchodilator response in horses with severe asthma during remission

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background During clinical remission of severe equine asthma (SEA), affected animals can be challenging to distinguish from healthy horses. In humans, the degree of bronchodilation achieved with a β2‐adrenergic bronchodilator is helpful in differentiating asthmatics from healthy subjects.

Defining the pollinator garden: is conceptual flexibility a feature or a bug?

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Ecologists often aim to reduce conceptual ambiguity by attempting to create rigid shared lexicons. These efforts imply that ambiguity is undesirable. In some contexts, however, conceptual flexibility comes with under‐discussed benefits. Here, we use the lens of pollinator gardening to explore how conceptual flexibility is built into participatory ...

Climate change effects on biomass and greenhouse gas emissions are ameliorated by nontoxic endophytes in southeastern USA transition zone tall fescue pastures

open access: yesGrassland Research, EarlyView.
Tall fescue produces more biomass and less carbon dioxide from the soil when it contains its beneficial fungal endophyte. Increased temperatures projected with climate change reduce fescue biomass, while altered rainfall frequency does not. Altering rainfall frequency and increasing temperatures can reduce carbon dioxide emissions from soil.
