The vulnerability of British aquatic insects to climate change
Freshwater ecosystems are particularly at risk from climate change due to the intrinsic link between the physical properties of the water environment and those species that live there. Mayflies, stoneflies and caddisflies are key indicators of the health

Endemic Flora and Fauna of Arkansas [PDF]
Arkansas has an amazing diversity of plants and animals contained within its political boundaries. Forty-seven taxa are reported as Arkansas endemics, including seven plants, thirteen crustaceans (two amphipods, three isopods, eight crayfishes), nine ...

Clouds, shadows, or twilight? Mayfly nymphs recognise the difference [PDF]
1. We examined the relative changes in light intensity that initiate night-time locomotor activity changes in nymphs of the mayfly, Stenonema modestum (Heptageniidae).

The Return of \u3ci\u3eHexagenia\u3c/i\u3e (Ephemeroptera: Ephemeridae) to the Lower Fox River, Wisconsin [PDF]
Burrowing mayflies (Hexagenia bilineata) were collected in 1991 in the vicinity of the DePere dam on the Fox River, Brown County, Wisconsin. Because Hexagenia mayflies are indicators of good water quality, their emergence from the Fox River is evidence ...

Fish predation cues induce drifting and emergence in an experimental stream mesocosm system
Abstract Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters ...

Surface Tension dominates Insect Flight on Fluid Interfaces
Flight on the two-dimensional air-water interface, with body weight supported by surface tension, is a unique locomotion strategy well adapted for the environmental niche on the surface of water.
