Are type 3 functional responses just statistical apparitions?

open access: yesEcosphere
Type 3 (sigmoidal) functional responses can protect rare prey from predation, but such functional responses are not often described. It is also not clear that factors that are hypothesized to promote type 3 functional responses, such as predator–prey ...

The Potential of Parapanteles hyposidrae and Protapanteles immunis (Hymenoptera: Braconidae) as Biocontrol Agents for the Tea Grey Geometrid Ectropis grisescens (Lepidoptera)

open access: yesInsects, 2022
The tea grey geometrid Ectropis grisescens has long been a significant insect pest of tea plants in China. Two parasitoids, Parapanteles hyposidrae and Protapanteles immunis (Hymenoptera: Braconidae: Microgastrinae), are the most important parasitoids in

Generalist bird exhibits site‐dependent resource selection

open access: yesEcology and Evolution, 2021
Quantifying resource selection (an organism's disproportionate use of available resources) is essential to infer habitat requirements of a species, develop management recommendations, predict species responses to changing conditions, and improve our ...

Functional Response and Intraspecific Competition in the Fall Armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae)

open access: yesInsects, 2020
Functional responses of the fall armyworm (FAW) larvae at each stage, and their intraspecific competition associated with cannibalism, provide insights into developing pest management strategies for the FAW.

Feeding on epibenthic zooplankton by Long‐tailed Ducks: patch structure, profitability, and food web implications

open access: yesEcosphere, 2021
Models of the trophic needs and impacts of mobile predators in food web networks typically do not consider interactions between prey dispersion and threshold prey densities needed for profitable foraging. As a result, the biomass of predators that can be

Considerations When Applying the Consumer Functional Response Measured Under Artificial Conditions

open access: yesFrontiers in Ecology and Evolution, 2021
Since its creation, considerable effort has been given to improving the utility of the consumer functional response. To date, the majority of efforts have focused on improving mathematical formulation in order to include additional ecological processes ...
