Understanding how functional traits vary across space and time is important to elucidate fundamental ecological processes determining species diversity, community structure and ecosystem functioning. The advent of the Anthropocene and its different influences on the environment, and thus on organisms in affected environments, has increased the urgency to gain a more mechanistic understanding of...

Life history responses are expected to accompany climate warming, yet little is known how long-term effects of climate and environmental change affect the seasonal dynamics of planktonic organisms. We used an historical data set from Lake Washington (U.S.A.) to quantify population responses of a calanoid copepod (Leptodiaptomus ashlandi) to long-term changes in temperature and resource availabi...

Heteropteran predators constitute an important component of predatory guilds in terrestrial and aquatic ecosystems. Most heteropteran species have generalist diets, and intraguild predation has been documented in most heteropteran families. Zoophytophagous species also frequently engage in intraguild interactions. An increase in extraguild prey density is often predicted to reduce intraguild pr...

Several recent publications have drawn attention to the increasing evidence of an ongoing global insect decline (see a review by Wagner et al., 2021), and terms such as ‘insect apocalypse’ collapse’ are becoming increasingly popular. The decrease in abundance affects almost all orders, butterflies (Papilionoidea superfamily) not exception (Warren 2021). In Europe, probably best-studied region r...

AND LAYPERSON SUMMARY OF PROJECT ACCOMPLISHMENTS Brown Marmorated Stink Bug (BMSB) was found in increasing numbers in vineyards in Oregon from 2013-2016. In California, BMSB was found in areas closely bordering vineyards, but not in any vineyards to date. Temperatures above and below feeding thresholds (Low=6°C, High =26°C) result in cessation of feeding. Older life stages such as adults were f...
