Behavior, nutrition, and environment drive survival of a large herbivore in the face of extreme winter conditions

Ecosphere, 2023
For many species, behavioral modification is an effective strategy to mitigate negative effects of harsh and unpredictable environmental conditions. When behavioral modifications are not sufficient to mitigate extreme environmental conditions, intrinsic ...

Field surveys reveal physicochemical conditions promoting occurrence and high abundance of an invasive freshwater snail (Potamopyrgus antipodarum) [PDF]

Aquatic Invasions, 2023
Environmental conditions promoting the occurrence and high abundance of non-native taxa are linked to critical stages of species invasions: establishment, whether a site can sustain a population of the non-native taxon, and impact, the extent to which ...

Rhizosphere microbial community composition shifts diurnally and in response to natural variation in host clock phenotype

mSystems, 2023
Plant-associated microbial assemblages are known to shift at time scales aligned with plant phenology, as influenced by the changes in plant-derived nutrient concentrations and abiotic conditions observed over a growing season. But these same factors can

Cats and dogs: A mesopredator navigating risk and reward provisioned by an apex predator

Ecology and Evolution, 2022
Successfully perceiving risk and reward is fundamental to the fitness of an animal, and can be achieved through a variety of perception tactics. For example, mesopredators may “directly” perceive risk by visually observing apex predators, or may ...

Modular Lipoprotein Toxins Transferred by Outer Membrane Exchange Target Discrete Cell Entry Pathways

mBio, 2021
Many bacterial species use diverse systems to deliver bacteriocins or toxins to neighboring competing cells. These systems are often selective in targeting cells that are related to themselves and therefore compete in the same niches for resources.

Thermodynamic Limits to Molecular Doping in Conjugated Polymers: A Perspective on Phase Behavior and Miscibility

Advanced Materials, EarlyView.
Molecular doping of conjugated polymers is fundamentally constrained by thermodynamic phase behavior. This Perspective reframes doping efficiency and stability in terms of miscibility limits, binodals, and solvus boundaries, highlighting the role of effective interaction parameters and charge transfer.
