Bottom-up branch dieback and sapling mortality of eastern white pine (Pinus strobus L.) has been observed range-wide during the last two decades. Observational studies thus far implicate these symptoms to an insect, the eastern white pine bast scale

Eastern white pine (Pinus strobus L.) is one of the most important conifer species across eastern North America. However, emerging health issues of eastern white pine have increased dramatically in recent decades, raising serious concerns over the he

Eastern white pine (Pinus strobus L.) is a widespread conifer in eastern North America. A novel dieback phenomenon, as well as increasing global temperatures contributing to the contraction of suitable habitat, is threatening this species’ long-ter

The literature on modelling a predator’s prey selection describes many intuitive indices, few of which have both reasonable statistical justification and tractable asymptotic properties. Here, we provide a simple model that meets both of these crit

Generalist predators are capable of selective foraging, but are predicted to feed in close proportion to prey availability to maximize energetic intake especially when overall prey availability is low. By extension, they are also expected to feed in

A number of arthropods, including some spiders, forgo diapause as an overwintering strategy and are instead active at low temperatures. The higher metabolic rates and periodic foraging behavior associated with winter activity, however, can be incompa

Lady beetles typically lay eggs in clusters, and clutch-mates that emerge near to each other might benefit in multiple ways. For example, lady beetle larvae are attracted to the pheromone released by aphids under attack. Thus, one potential advantage

A generalist predator's ability to contribute to biological control is influenced by the decisions it makes during foraging. Predators often use flexible foraging tactics, which allows them to pursue specific types of prey at the cost of reducing the
