In field biology, interactions between wildlife and in situ equipment occur often. These interactions have the potential to induce a variety of behaviours in local fauna. Here, we note the destructive behaviour exhibited by the Muskrat (Ondatra zibethicus) following deployment of aquatic invertebrate traps for research purposes at 12 wetlands located in central Saskatchewan. Of 24 aquatic insect emergence traps used on seven wetlands in our study, 14 (58%) required recurring repairs. In addition, on several occasions, leaf litter bags and their anchoring stakes were torn or chewed. The recurring damage took place in wetlands with Muskrat lodges. We recommend structural modifications to aquatic invertebrate traps in wetland complexes densely inhabited by Muskrats and other semi-aquatic rodents.

Traditionally, exploration of ecosystems in the context of undergraduate education has been restricted to connections within conventionally defined habitats (i.e., within a stream, within a forest). Further, instruction regarding the aquatic-terrestrial interface has emphasized directional inputs from land to water. However, a relatively new body of research has characterized reciprocal interactions and draws attention to fluxes from water to land, including the emergence of aquatic insects that serve as prey for terrestrial predators. We present a guide to an inquiry-based lesson for undergraduate biology that explores interactions and connections across aquatic and terrestrial habitat boundaries. The focus is on cross-habitat linkages within ecosystems, specifically addressing the question, What is the role of insect emergence in connecting the web of life linking aquatic and terrestrial habitats and organisms? Students (1) engage with a documentary film, (2) explore insect emergence and make observations of riparian insectivores, (3) explain the collected data, (4) elaborate on alternative study designs and a measure of ecosystem health, and (5) evaluate their new understanding. This lesson addresses core concepts and competencies for undergraduate biology education, as identified in the Vision and Change report.

Abstract The timing and spatial distribution of aquatic insect emergence is linked to the abiotic and biotic environment in streams. Studies of aquatic insect emergence are needed to generate baseline data to identify potential shifts in phenology and habitat-related emergence with global change. The purpose of this study was to 1) compare the timing of Plecoptera (stonefly) species emergence between two streams with different thermal regimes and 2) characterize the distribution of emerging Plecoptera and Trichoptera (caddisflies) from wood, rock, gravel, and sand substrates in five forested, headwater streams. Emergence timing and duration varied among Plecoptera species, with Ostrocerca albidipennis (Walker) (Plecoptera: Nemouridae) emerging only in May and four species in the genus Leuctra (Plecoptera: Leuctridae) collectively emerging throughout the summer (May to September). We observed earlier emergence of Amphinemura nigritta (Provancher) (Plecoptera: Nemouridae) and a longer total emergence period for Leuctra ferruginea (Walker) (Plecoptera: Leuctridae) in the stream with ~1.5°C warmer temperatures, which suggested that some insects may experience phenological shifts in streams with subtle differences in temperature. The abundance of plecopteran and trichopteran taxa emerging from wood was generally greater than for gravel or sand, and sand was the least preferred emergence substrate. The results suggest that human actions that decrease large wood and increase fine sedimentation may decrease habitat quality for many insect larvae and limit preferred emergence substrates.
