Experiments on the influence of Chaoborus brasiliensis Theobald, 1901 (Diptera: Chaoboridae) on the diel vertical migration of microcrustaceans from Lake Monte Alegre, Brazil Experimentos sobre a influência de Chaoborus brasiliensis (Diptera: Chaoboridae) sobre a migração vertical de microcrustáceos do Lago Monte Alegre, Brasil [PDF]
The aim of this work was to evaluate whether diel vertical migration of microcrustaceans from Lake Monte Alegre is related to invertebrate predators, namely larvae of Chaoborus brasiliensis. The hypothesis tested in the experiments was that the migratory

Behavioral and neurobiological implications of kairomones for rodents: an updated review [PDF]
Like many other vertebrates, rodents communicate via pheromones, which favors intraspecies communication. In contrast, kairomones are semiochemicals involved in interspecific communication, facilitating information between organisms of different species ...

Non‐Consumptive Effects of Cannibalism Elicit a Metabolic Response in Dragonfly Larvae [PDF]
Predator–prey interactions typically involve changes in metabolic rates associated with hunting, foraging, and activation/maintenance of defense mechanisms. Similar response can result from non‐consumptive effects mediated by chemical cues, such as alarm

A Review of the Host Plant Location and Recognition Mechanisms of Asian Longhorn Beetle [PDF]
The Asian longhorn beetle (ALB), Anoplophora glabripennis Motschulsky, is a polyphagous xylophage with dozens of reported host tree species. However, the mechanisms by which individuals locate and recognize host plants are still unknown. We summarize the

Identification of pyridine analogs as new predator-derived kairomones. [PDF]
In the wild, animals have developed survival strategies relying on their senses. The individual ability to identify threatening situations is crucial and leads to increase in the overall fitness of the species.

Phenotypic and Transcriptomic Analysis Revealed a Lack of Risk Perception by Native Tadpoles Toward Novel Non‐Native Fish [PDF]
The introduction of alien species poses a serious threat to native biodiversity, and mountain lake systems in the southwest of China are particularly vulnerable to the introduction of non‐native fish.

Acidification and γ-aminobutyric acid independently alter kairomone-induced behaviour [PDF]
Exposure to high pCO2 or low pH alters sensation and behaviour in many marine animals. We show that crab larvae lose their ability to detect and/or process predator kairomones after exposure to low pH over a time scale relevant to diel pH cycles in ...

Prey-Foraging Patterns in a Complex Landscape of Fear. [PDF]
Prey antipredator defenses may weaken when a predator is cannibalistic or stressed, but it remains unclear which predator prey systems show this effect and how strongly it shapes trophic cascades. In our aquatic food chain (higher order predator, mesopredator, and mesopredator's prey), we found no defense suppression in mesopredators exposed to ...

Niche Breadth and Olfactory Context Shape Informed Passive Dispersal. [PDF]
Experimental evolution reveals that niche breadth modulates informed passive dispersal in phytophagous mites through divergent strategies. While generalists optimise take‐off based on target cue familiarity and signal‐to‐noise ratios, specialists primarily track current host quality to trigger departure.
