Invertebrate attack rates in crop fields are driven by prey toughness rather than size

Basic and Applied Ecology
Insect pests vary in size and toughness across species and life stages, and are attacked to varying degrees by different predators. Feeding experiments suggest that both prey and predator (e.g. carabid) traits shape these predator–prey interactions. Here,

IMPACT OF FEAR BEHAVIOR ON PREY POPULATION GROWTH PREY-PREDATOR INTERACTION

Barekeng, 2022
Experiments on the living environment of vertebrate ecosystems, it has been shown that predators have a massive influence on the demographic growth rate of prey.

Modeling predator-prey dynamics with stochastic differential equations: Patterns of collective hunting and nonlinear predation effects

Alexandria Engineering Journal
We investigate predator–prey school interactions in aquatic environments using a stochastic differential equation (SDE)-based, particle-level model that incorporates attraction, repulsion, alignment, and environmental noise.

Asymmetry in Skipping Enhances Viability Against Control Input Noise

Advanced Robotics Research, EarlyView.
Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...

Underground Signals: The Ecological Power of Root Volatiles

Advanced Science, EarlyView.
Root volatiles mediate rhizosphere chemical communication, shaping interactions among plants, microbes, herbivores, and natural enemies. Their production, transport, and perception underpin ecological adaptation, multitrophic interactions, and plant resilience, offering opportunities for sustainable crop protection, resilient agroecosystems, and ...

Predator-prey interactions in freshwater ecosystems [PDF]

, 2022
Predator-prey interactions are fundamental drivers of community structure and energy flow in freshwater ecosystems,regulating prey population sizes, shaping prey behavioural and morphological traits through predation pressure, andmediating trophic ...

Deep Learning‐Driven Discovery and Engineering of an Efficient PETase for Depolymerization and Detoxification of PET Microplastics Under Physiological Conditions

Advanced Science, EarlyView.
A deep learning–driven pipeline mining 246 million protein sequences uncovers AhPETase, an evolutionarily distinct PET hydrolase. Engineered variant AhPETaseM1 degrades post‐consumer PET microplastics under physiological conditions and reverses microplasticinduced cytotoxicity in human lung and colon cells, establishing enzymatic microplastic ...

Prey-Predator Model with a Nonlocal Bistable Dynamics of Prey

Mathematics, 2018
Spatiotemporal pattern formation in integro-differential equation models of interacting populations is an active area of research, which has emerged through the introduction of nonlocal intra- and inter-specific interactions.

Behavioural syndrome in a solitary predator is independent of body size and growth rate. [PDF]

, 2012
Models explaining behavioural syndromes often focus on state-dependency, linking behavioural variation to individual differences in other phenotypic features. Empirical studies are, however, rare.

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

Advanced Science, EarlyView.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...
