The orientation of Tribolium castaneum adults in the presence of aggregation pheromone 4,8-Dimethyldecanal and food oils

open access: yesJulius-Kühn-Archiv, 2018
Monitoring of Tribolium castaneum, the red flour beetle, involves the use of aggregation pheromone 4,8- dimethyldecanal (4,8 DMD) and kairomones such as cereal oils.

Vibrational Signals for Mating Disruption Do Not Negatively Affect Grapevine Growth and Production

open access: yesAustralian Journal of Grape and Wine Research, Volume 2026, Issue 1, 2026.
Vibrational mating disruption (VMD) is a promising strategy to control Scaphoideus titanus populations in vineyards, and it is based on the prolonged application of a species‐specific disturbance vibrational signal (DVS) on grapevines. Plants can react by different transcriptional, physiological, and morphological changes, according to the source and ...

Size‐specific reduction in kelp consumption by New Zealand urchins exposed to chemical cues from the red rock lobster

open access: yesEcosphere
Sea urchins can strongly reduce their mobility, exposure to predation, and feeding rates upon detection of chemical cues produced by predators, driving behavioral effects on grazing activity that may contribute to macroalgal community dynamics.

Ecological and evolutionary factors of intraspecific variation in inducible defenses: Insights gained from Daphnia experiments

open access: yesEcology and Evolution, 2020
Phenotypic variation among individuals and species is a fundamental principle of natural selection. In this review, we focus on numerous experiments involving the model species Daphnia (Crustacea) and categorize the factors, especially secondary ones ...

Diel vertical migration strategies of zooplankton in oligotrophic Russell Pond, New Hampshire [PDF]

open access: yes, 2014
Russell Pond is an ultra-oligotrophic lake with low chlorophyll a (1.9 mg L-1), total phosphorus (3.4 mg L-1), high Secchi Disk (10.4 m) and high light transmission (water coefficient of water, kw=0.33). Vertical migration of Chaoborus, Bosmina, Daphnia,

(2R,5S)-theaspirane identified as the kairomone for the banana weevil, Cosmopolites sordidus, from attractive senesced leaves of the host banana, Musa spp. [PDF]

open access: yes, 2018
The principal active component produced by highly attractive senesced host banana leaves, Musa spp., for the banana weevil, Cosmopolites sordidus, is shown by coupled gas chromatography‐electroantennography (GC‐EAG), coupled GC‐mass spectrometry (GC‐MS),

Prolonged low flows and non‐native fish operate additively to alter insect emergence in mountain streams

open access: yesLimnology and Oceanography, Volume 70, Issue S2, Page S377-S391, December 2025.
Abstract Climate‐induced flow alteration is decreasing snowpack and advancing snowmelt, subjecting mountain streams to longer low‐flow periods. Yet, anticipating how stream ecosystems respond to prolonged low flows remains challenging because distinct trophic levels can respond differently, and non‐native predators can dampen or amplify responses. Here,

Red Flour Beetle Response to Traps with Prior Captures [PDF]

open access: yes, 2018
The red flour beetle (Tribolium castaneum) is a major pest of food facilities such as flour mills and is often monitored using pitfall type traps with a food oil and pheromone attractant.

Predation Risk Perception in Daphnia carinata Induced by the Milt of Common Carp (Cyprinus carpio) [PDF]

open access: yes, 2010
Numerous experimental studies suggest that many organisms can sense predation risk and subsequently adjust their life history, behavior, and morphology as adaptations to predators.

Plasticity in climate change responses

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2508-2527, December 2025.
ABSTRACT Recent research has shown that climate change can both induce and modulate the expression of plastic traits but our understanding of the role of phenotypic plasticity as an adaptive response to climate change is limited. In this review, we dissect the mechanisms and impact of phenotypic plasticity as a response to accumulating climatic ...
