Integrating a Shifting Coast: Setting a precedent for Interspecific Interaction
… nonhuman and human needs particularly to foster interspecific interactions that without design intervention may or may not have been realized. Similar to the common practice of nonhumans such as birds and squirrels being provided for with baths and feeders, this work will investigate how and why …

Interaction strengths and net effects in food web models
… to inform the scaling of intraspecific and interspecific interaction strengths in a three species food chain and a series of theoretical analyses on the changes to equilibrium biomass abundances following press perturbations. The empirical experiment is a consequence of the difficulties …

Dietary Shifts, Niche Relationships and Interspecific Competition in Sympatric Grey Langur (Semnopithecus entellus) and Purple-faced Langur (Trachypithecus vetulus) in Sri Lanka
… is a fundamental question in ecology. Interspecific competition has been shown to influence the behavior and ecology of organisms in a wide range of ecological communities. However, the broader role of interspecific competition in primate communities is unclear as relatively few studies …

Variation in Social Behavior Throughout the Estrous Cycle of a Captive Killer Whale <i>Orcinus orca</i>
… in the killer whale, and (b) document a rare interspecific interaction. A total of five estrous cycles, covering the span of eight months, were analyzed in the present study. Weekly blood serum samples from the female killer whale were analyzed to ascertain the estrous cycle phase of this …

Coevolution Between Grasshopper mice (Onychomys spp.) and Bark and Striped Scorpions (Centruroides spp.)
… against a predator may be increased when the interaction is with a "dangerous" prey. Predators are most likely to respond evolutionarily to potentially lethal prey. This study employs grasshopper mice (Onychomys spp.) and bark and striped scorpions (Centruroides spp.) as a model to test the …

THE ECOLOGICAL IMPORTANCE AND EVOLUTIONARY POTENTIAL OF PHENOTYPIC PLASTICITY IN NOVEL ENVIRONMENTS
… without interacting with other organisms. Biotic interactions are important drivers of species distributions and trait evolution and new interactions are analogous to novel environments. Biotic interactions are predicted to influence plasticity evolution, but this has been challenging to test and …

Community Structure of Parasitoids Attacking Leaf Galls of Belonocnema treatae on Quercus fusiformis
… timing of attack, 3) elucidating the nature of interactions among parasitoid species, and 4) determining the cumulative effect of parasitoids on B. treatae survivorship. The objectives were addressed using an exclosure study which limited access of parasitoids to leaf galls to a series of …

New insights for the Drosophila suzukii sustainable control: integrating parasitoids into current pest management strategies
Nell’attuale era della globalizzazione, gli artropodi fitofagi rappresentano una delle principali minacce per l’agricoltura e l’ambiente. Il moscerino dei piccoli frutti, Drosophila suzukii (Matsumura), è un importante esempio di insetto invasivo responsabile di ingenti perdite economiche a …
