From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Sperm Transfer Under Behavioral and Morphological Constraints in the Orb‐Web Spider Genus Argiope

Integrative Zoology, EarlyView.
The polygamous mating system of the orb‐web spider genus Argiope provides a model to study the evolution of sperm transfer under morphological and behavioral constraints. This helps us to understand how male and female behavioral and morphological reproductive traits influence sperm transfer.

Effect of temperature on cannibalism rate between green lacewings larvae (Chrysoperla carnea [Stephens], Neuroptera, Chrysopidae)

Acta Agriculturae Slovenica, 2009
Paper presents a larval cannibalism of green lacewings (Chrysoperla carnea), which was observed during the laboratory bioassay on non-target effect of entomopathogenic nematodes against green lacewings larvae.

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

Integrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Quantifying functionally equivalent species and ecological network dissimilarity with optimal transport distances

Methods in Ecology and Evolution, EarlyView.
Abstract Quantifying the structure and dynamics of species interactions in ecological communities is fundamental to studying ecology and evolution. While there are numerous approaches to analysing ecological networks, there is not yet an approach that can (1) quantify dissimilarity in the global structure of ecological networks that range from ...

Occurrence and evolution of cannibal behaviour in extant snakes

Biological Reviews, EarlyView.
ABSTRACT Extant snakes (Serpentes) are a highly diverse group of squamate reptiles, which have independently evolved key morphological adaptations to consume a large variety of vertebrate and invertebrate prey. While these predator–prey interactions have been widely addressed by several studies, little is known regarding the occurrence of cannibal ...

Plant Domestication Affects the Oviposition Behavior and Performance of Ganaspis kimorum, a Parasitoid of Drosophila suzukii

Entomologia Experimentalis et Applicata, EarlyView.
In this study, we investigated the effects of blueberry domestication on the oviposition behavior and performance of Ganaspis kimorum, a parasitoid of Drosophila suzukii. Domestication of blueberries reduced the oviposition‐searching behavior of the parasitoid but enhanced parasitoid performance, including offspring performance. Additionally, blueberry

No Appeasement Through Vibrations: Male Vibratory Pre‐Copulatory Courtship in the Cursorial Spider Pisaura mirabilis Does Not Affect Female Predatory Response

Ethology, EarlyView.
Male courtship can serve various purposes such as species recognition, mate localization, or advertisement of individual quality and physical condition. In predatory species such as spiders, courtship activity by the male might also reduce the risk of being predated on by the female.

Cell Cannibalism in Oral Precancerous Lesions and Squamous Cell Carcinoma [PDF]

Iranian Journal of Otorhinolaryngology
Introduction:Cellular cannibalism is defined as a process of non-apoptotic cell death. This phenomenon has been indicated to be associated with aggressiveness, anaplasia, invasiveness, and metastatic potential of various malignancies.

An Easy Method to Sample Headspace Pheromones in the Field

Ethology, EarlyView.
Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.
