Implications of the Attenuated Allee Effect on Population Dynamics

The Allee effect is an ecological phenomenon characterized by a per capita growth rate that increases as the population size increases in the context of low population density. The Allee effect can lead to rapid extinction events.

The Effects of the Weak Allee Effect and Disease on the Dynamics of a Predator–Prey System: Stability and Bifurcation Properties

Axioms
In this paper, an eco-epidemiological model with a weak Allee effect and prey disease dynamics is discussed. Mathematical features such as non-negativity, boundedness of solutions, and local stability of the feasible equilibria are discussed ...

Learning from/with New Hampshire's Spanish‐speaking community: Building an internship program for Spanish students

Foreign Language Annals, EarlyView.
Abstract This article illustrates the implementation of a pilot internship program for Spanish language students with a public‐facing component at a small, predominantly white, private liberal arts college in the northeastern U.S. This project focused on providing students with the possibility to cooperate and collaborate with organizations that ...

Using Catch Data to Estimate Changes in Global Commercial Abalone Abundance

Fisheries Management and Ecology, EarlyView.
ABSTRACT Changes in global wild capture production of abalone are explored to infer potential changes in biological stocks. The study found that 77% (or 10 out of the 13) of the countries that reportedly caught abalone in the wild have experienced declines in catches between 1980 and 2023, and on aggregate catch declined by almost 83% between 1980 and ...

Dispersal mediates metapopulation response to local and regional stressors

Insect Conservation and Diversity, EarlyView.
A feature of recent insect declines is that widespread, formerly common species are among the worst affected. We designed a metapopulation simulation to ask how dispersal capability interacts with landscape and population stressors that act at different spatial scales.

Association of Interleukin‐17F Polymorphisms (rs763780, rs9382084, rs2397084, and rs12203582) With Gastric Cancer Susceptibility According to Helicobacter pylori Infection Status

International Journal of Immunogenetics, EarlyView.
ABSTRACT Single nucleotide polymorphisms (SNPs) in the interleukin‐17F (IL‐17F) gene may modulate inflammatory responses, with distinct effects on inflammation and tumour progression. Helicobacter pylori infection, a Group 1 carcinogen, is strongly associated with gastric cancer (GC) development.

Black Carp Mylopharyngodon piceus reproductive development and maturation in the Mississippi River basin

Journal of Fish Biology, EarlyView.
Abstract Black Carp Mylopharyngodon piceus are native to most major east Asian drainages and are internationally cultured for use as a food‐fish or a biological control for molluscs. We describe the reproductive biology of Black Carp from the growing invasive population in the Mississippi River basin through examination of incidental commercial ...

Dynamics of a prey-predator system under the influence of the Allee effect and Holling type-II functional response [PDF]

Network Biology
Capturing complicated dynamics and understanding the underlying controlling ecological processes is one of the major ecological issues. The Allee effect is an essential component in ecology, and considering it can have a substantial impact on system ...

Management of invasive Allee species

Letters in Biomathematics, 2017
In this study, we use a discrete, two-patch population model of an Allee species to examine different methods in managing invasions. We first analytically examine the model to show the presence of the strong Allee effect, and then we numerically explore ...
