Optimal L\'{e}vy-flight foraging in a finite landscape
, 2014 We present a simple model to study L\'{e}vy-flight foraging in a finite landscape with countable targets. In our approach, foraging is a step-based exploratory random search process with a power-law step-size distribution $P(l) \propto l^{-\mu}$. We find

The topography of the environment alters the optimal search strategy for active particles [PDF]
, 2017 In environments with scarce resources, adopting the right search strategy can make the difference between succeeding and failing, even between life and death.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots
Advanced Robotics Research, EarlyView.Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Larval predation on different instars in blowfly populations
Brazilian Archives of Biology and Technology, 2004 During its larval stage, Chrysomya albiceps (Diptera: Calliphoridae) is a facultative predator on other blowflies. In this study, we evaluated the predation by third instar larvae of C.

Foraging Behavior of Tetramorium Caespitum in an Urban Environment: the Effect of Food Quality on Foraging [PDF]
, 2016 Animals\u27 foraging strategies are directly related to their fitness. Proposed models of optimal foraging assume that animals strategize in terms of maximizing benefits over the cost of acquiring resources. Ants are social insects that are comparable in

The emergence of leaders and followers in foraging pairs when the qualities of individuals differ [PDF]
, 2008 Background Foraging in groups offers animals a number of advantages, such as increasing their likelihood of finding food or detecting and avoiding predators.

Advanced Robotics Research, EarlyView.Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Predicting trophic relations in ecological networks: a test of the Allometric Diet Breadth Model [PDF]
, 2009 Few of food web theory hypotheses/predictions can be readily tested using empirical data. An exception is represented by simple probabilistic models for food web structure, for which the likelihood has been derived.

From Lab to Landscape: Environmental Biohybrid Robotics for Ecological Futures
Advanced Robotics Research, EarlyView.This Perspective explores environmental biohybrid robotics, integrating living tissues, microorganisms, and insects for operation in real‐world ecosystems. It traces the leap from laboratory experiments to forests, wetlands, and urban environments and discusses key challenges, development pathways, and opportunities for ecological monitoring and ...

Optimal foraging predicts the ecology but not the evolution of host specialization in bacteriophages. [PDF]
PLoS ONE, 2008 We explore the ability of optimal foraging theory to explain the observation among marine bacteriophages that host range appears to be negatively correlated with host abundance in the local marine environment.
