Oikos, EarlyView.Competition theory suggests that interspecific prey competition can result in changes to the dietary niche, but obtaining timeseries of data from sympatric species experiencing temporal variation in competition is challenging. Scotland is an important area for two species of seals, but over the past 20 years, populations of harbour seals Phoca vitulina

Critters in the Workplace: Bedbugs [PDF]
, 2019 Unfortunately, critter infestations do exist in the workplace and people tend not to want to talk about them. All kinds of workplaces have had problems or infestations: hotels, hospitals, office buildings, department stores, and TV studios, as well as ...

Oikos, EarlyView.Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Effects of bioinsecticide exposure route on aphids and their natural enemies in oilseed rape
Pest Management Science, EarlyView.Fatty acids, silicone polymers and surfactants reduced aphid numbers but caused natural enemy mortality under direct exposure, while minimal residual activity suggests potential for targeted, compatible use in integrated pest management. Abstract BACKGROUND Myzus persicae Sulzer and Brevicoryne brassicae L.

Pest Management Science, EarlyView.Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Spatial and seasonal relationships between Pacific harbor seals (Phoca vitulina richardii) and their prey, at multiple scales [PDF]
, 2009 Knowing where pinnipeds forage is vital to managing and protecting their populations, and for assessing potential interactions with fisheries. We assessed the spatial relationship between the seasonal distribution of Pacific harbor seals (Phoca vitulina

Plant structural complexity and mechanical defenses mediate predator-prey interactions in an odonate-bird system. [PDF]
, 2017 Habitat-forming species provide refuges for a variety of associating species; these refuges may mediate interactions between species differently depending on the functional traits of the habitat-forming species.

Pest Management Science, EarlyView.Rhizobacterial inoculation of barley reduced Sitobion avenae populations by inducing plant resistance and modifying volatiles that attracted parasitoid wasps earlier, enhancing both bottom‐up and top‐down pest control. Abstract BACKGROUND Soil rhizobacteria can enhance crop resistance to insect herbivores and influence higher trophic interactions ...

Remote Sensing in Ecology and Conservation, EarlyView.The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this
