Proteomic analysis of Daphnia magna hints at molecular pathways involved in defensive plastic responses [PDF]

, 2014
Background: Phenotypic plasticity in defensive traits occurs in many species when facing heterogeneous predator regimes. The waterflea Daphnia is well-known for showing a variety of these so called inducible defences.

Time‐delayed effects on population dynamics can generate hidden costs of plasticity and enable coexistence

Functional Ecology, Volume 39, Issue 11, Page 3197-3209, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Inducible defences allow organisms to adapt to variable predation risk. Whether this is beneficial or not, however, depends on two traits: how accurately they can detect current predation risk and how rapidly they can switch between phenotypes.

Effect of Commercial Trap Design and Location on Captures of Diocalandra frumenti (Fabricius) (Coleoptera: Dryophthoridae) on Palm Trees

Insects
Diocalandra frumenti (Fabricius) (Coleoptera: Dryophthoridae) is a weevil present in the Canary Islands, affecting economically important palms such as Phoenix canariensis H. Wildpret and its hybrids, for which there were no trapping tools.

Tadpoles in Complex Environments: How Temperature, Desiccation Risk, and Predators Shape Larval Plasticity in a Tropical Frog

Freshwater Biology, Volume 70, Issue 11, November 2025.
ABSTRACT Organisms have often evolved developmental plasticity to cope with environmental heterogeneity, but natural systems are often quite complex and organisms have to assess and respond to variation in multiple environmental factors simultaneously, which at times can elicit opposing or synergistic phenotypic responses.

The response of an egg parasitoid to substrate-borne semiochemicals is affected by previous experience [PDF]

, 2016
Animals can adjust their behaviour according to previous experience gained during foraging. In parasitoids, experience plays a key role in host location, a hierarchical process in which air-borne and substrate-borne semiochemicals are used to find hosts.

Exploring the Influence of Insect Honeydew on Plant Physiology and Health: Bridging the Gap in Current Understanding

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Honeydew, a sugary excretion from sap‐feeding insects, significantly influences plant‐insect interactions. While extensive research has examined honeydew's composition, regulation, and role in insect‐plant relationships, its direct effects on plant physiology and health remain understudied.

Variations in gut microbiota associated with changes in life-history traits of Daphnia galeata induced by fish kairomones

Frontiers in Ecology and Evolution
The gut microbiota plays a crucial role in host physiology and the disruption of host–microbiota relationships caused by environmental stressors can impact host growth and survival.

Stronger Antipredatory Vigilance of Prey to Olfactory Cues From Injured Vulnerable Conspecifics

Ecology and Evolution, Volume 15, Issue 10, October 2025.
Eggs of spider mites are more vulnerable to predators. Reproductive females of spider mites are more vigilant to olfactory cues from injured eggs compared to that from injured adults and deutonymphs. ABSTRACT Predation risk is a key evolutionary force shaping prey behaviors and life‐history strategies across taxa. Predators often target vulnerable life
