Dynamical of Prey Refuge in a Diased Predator-Prey Model with Intraspecific Competition for Predator

JTAM (Jurnal Teori dan Aplikasi Matematika)
The predator-prey model described is a population growth model of an eco-epidemiological system with prey protection and predator intraspecific traits. Predation interactions in predator species use response functions. The aim of this research is to examine the local stable balance point and look at the characteristics of species resulting from ...

Scaling temperature‐dependent dispersal rates to metacommunity dynamics: An experimental test

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Changes in community structure under shifting thermal regimes depend on how both local population dynamics and regional dispersal respond to temperature. Processes underlying dispersal, such as movement speed and demographic density dependence, are constrained by ...

Functional variation in butterfly egg pore traits: The potential role of climate

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Immobile eggs of terrestrial animals are exposed to variable environmental conditions. Insect egg pores, critical for gas exchange (aeropyles) and fertilisation (micropyles), are ecologically important yet understudied.

Extremely halophilic brine community manipulation shows higher robustness of microbiomes inhabiting human-driven solar saltern than naturally driven lake

mSystems
Hypersaline ecosystems display taxonomically similar assemblages with low diversities and highly dense accompanying viromes. The ecological implications of viral infection on natural microbial populations remain poorly understood, especially at finer ...

Predator behaviour and prey density: evaluating density-dependent intraspecific interactions on predator functional responses [PDF]

Journal of Animal Ecology, 2001
Abstract In models of size‐structured predator–prey systems, the effects are evaluated of gape‐size limited predation on prey population growth and density when predators are non‐interacting, cannibalistic, interfering, and cannibalistic and interfering.

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Interactions Between Non‐Native Western Mosquitofish and Native Bluegill Sunfish: Mesocosm Experiments

Ecology and Evolution
Aquatic ecosystems are often negatively affected by invasive species. However, biotic resistance by native species, either by competition or predation, can reduce the impacts of invasions by non‐native species. The Western Mosquitofish (Gambusia affinis)

What the Dying are Saying to the Living: Mixed Conspecific Alarm Cues Reverse Competitive Hierarchies by Reshaping Genotype-Specific Life Histories. [PDF]

Ecol Evol
This study demonstrates that the complexity of intraspecific alarm cues—specifically, whether they are from a single genetic source or a mixture—acts as a critical environmental filter. While genotype‐specific cues trigger a canonical adaptive “life‐history switch,” mixed cues induce a state of chronic stress, leading to genotype‐specific reprogramming

Boldness and niche width structure spatial interactions in a natural rodent community

Journal of Animal Ecology, EarlyView.
We show that individual behavioural differences (boldness) structure spatial encounter patterns within a natural multi‐species community. By linking personality to space use and interaction structure, our study demonstrates how intraspecific variation can scale up to shape community‐level processes.

Kin recognition during intraspecific predation by Harpacticus sp. (Copepoda: Harpacticoida)

, 2006
Female predation on developmental instars of its own as well as on conspecific alien offspring is reported for a new species of Harpacticus sp. from Hong Kong waters.
