Taking care of the enemy: egg predation by the Darwin wasp Tromatobia sp. (Ichneumonidae) on the cobweb spider Chrysso compressa (Araneae, Theridiidae) [PDF]

open access: yesJournal of Hymenoptera Research, 2023
Some wasp species use spiders as food resources, overcoming several anti-predator barriers that are exerted by spiders. Tromatobia ichneumonid wasps are spider egg predators that usually attack Araneidae species, although there are few records of ...

Black-throated blue warblers (Setophaga caerulescens) exhibit diet flexibility and track seasonal changes in insect availability. [PDF]

open access: yesEcol Evol
Changes in seasonality have extended the breeding window for migratory birds in North America with earlier springs and later autumns that affect insect availability. DNA metabarcoding and insect surveys revealed that migratory, insectivorous black‐throated blue warblers exhibit diet flexibility in response to seasonal pulses in arthropod prey ...

Edge Effects and Pitfall Trap Design Influence Spider Diversity and Assemblages in Canola Agroecosystems on the Canadian Prairies. [PDF]

open access: yesEcol Evol
Spiders are important generalist predators in canola agroecosystems, but their diversity remains poorly studied on the Canadian Prairies. We surveyed spider assemblages in the Aspen Parkland region and tested pitfall trap modifications to improve sampling.

Arthropod Food Webs in the Foreland of a Retreating Greenland Glacier: Integrating Molecular Gut Content Analysis With Structural Equation Modelling. [PDF]

open access: yesEcol Evol
This study investigates the ecological dynamics of arthropod predators across a transect of an Arctic glacier foreland, to understand how climate change impacts predator–prey interactions. By integrating ecological observations with DNA metabarcoding, our research elucidates the role of the key prey species in shaping spider populations in these ...

Effects of mowing on body size patterns in spider assemblages of mesic meadows. [PDF]

open access: yesEcol Evol
In the submitted paper, we described how mowing, as a strong habitat disturbance, influenced on mean, skewness and kurtosis of the body size in epigeic spider assemblages. We found that mowing had no significant effect on mean body size, skewness and kurtosis of the body size in epigeic spider assemblages.

Araneae communities associated with the canopies of chestnut trees in the northeastern part of Portugal: The influence of soil management practices

open access: yesEuropean Journal of Entomology, 2013
Chestnut (Castanea sativa Mill.) is one of the economically more important trees in the north of Portugal. Spiders, as generalist predators, are potential controlling agents of pests, yet the composition of the community of spiders associated with this ...
