Hatching with the enemy: Daphnia diapausing eggs hatch in the presence of fish kairomones [PDF]

, 2005
Infochemicals are known to play a key role in mediating predator-prey interactions, both in aquatic and terrestrial communities. However, state-dependent variation may exist in how effectively individuals can use this information, depending on genotype ...

A wolf in sheep's clothing: Predatory fish have convergent consumptive effects but divergent predation‐risk effects

Ecosphere, 2022
Although consumptive effects of predators have long been central to ecology, predation‐risk effects have emerged as major components of predator–prey interactions. Both consumptive and predation‐risk effects should vary with predator functional traits (e.

The scent of wolves: pyrazine analogs induce avoidance and vigilance behaviors in prey

Frontiers in Neuroscience, 2015
The common grey wolf (Canis lupus) is an apex predator located at the top of the food chain in the Northern Hemisphere. It preys on rodents, rabbits, ungulates, and many other kinds of mammal.

Community of Bark and Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae and Platypodinae) in Agricultural and Forest Ecosystems with Laurel Wilt

Insects, 2022
Redbay ambrosia beetle, Xyleborus glabratus, is an invasive wood-boring pest first detected in the USA in 2002 in Georgia. The beetle’s dominant fungal symbiont, Harringtonialauricola, causes laurel wilt, a lethal disease of trees in the Lauraceae.

Transcriptomic responses to predator kairomones in embryos of the aquatic snail Radix balthica [PDF]

, 2018
The ability of organisms to respond to predation threat by exhibiting induced defenses is well documented, but studies on the potential mechanistic basis for such responses are scarce.

Change in phenotypic plasticity of a morphological defence in Daphnia galeata (Crustacea: Cladocera) in a selection experiment

Journal of Limnology, 2007
Some water fleas Daphnia change their head morphology to reduce predation risk in response to chemical substances (kairomones) released from larvae of the invertebrate predator Chaoborus (Insecta: Diptera).

Attraction of Aulacophora foveicollis Lucas (Coleoptera: Chrysomelidae) to Host Plant Cucurbita maxima Duchesne (Cucurbitaceae) Volatiles

Agronomy, 2022
The volatiles extracted by the dynamic headspace collection system from the undamaged and conspecific damaged Cucurbita maxima were analyzed by Gas chromatography–mass spectrometry (GC-MS).

Many genes are differentially expressed in response to temperature changes, while kairomones have minimal observable effect at the level of transcript expression.

, 2022
Venn diagram of differentially expressed genes for Daphnia pulicaria clones (a) Blue and (b) Gardisky in response to temperature and predation cues. Cyan and purple sections illustrate differential expression from the introduction of predator cues (Y vs.

Tracking Short-Range Attraction and Oviposition of European Grapevine Moths Affected by Volatile Organic Compounds in a Four-Chamber Olfactometer

Insects, 2020
The identification of volatile organic compounds (VOCs) leading to short-range attraction and oviposition of the European grapevine moth Lobesia botrana and European grape berry moth Eupoecilia ambiguella (Lepidoptera: Tortricidae) is crucial in order to

Imidacloprid pesticide alters anti-predator responses in a water flea (Daphnia sinensis)

Water Biology and Security
Organisms develop inducible defense strategies to combat predators, altering behaviour, morphology, and life history to minimize predation risk.
