Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

Oikos, EarlyView.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...

Catchment conversion to agriculture alters freshwater macroinvertebrate community responses to flow disturbance: results from a replicated in‐stream experiment

Oikos, EarlyView.
Anthropogenic stressors often co‐occur in ecosystems, but their combined impacts are rarely assessed using field experiments. Press disturbances particularly can reshape community dynamics, altering their capacity to withstand or recover from acute pulse disturbances by modifying response diversity.

Urban‐driven homogenization of aquatic subsidy size structure cascades to riparian predator communities

Oikos, EarlyView.
The export of emergent aquatic insects is a critical energy subsidy for terrestrial food webs. While urbanization is known to alter stream communities, its effects on the size structure of these insect subsidies and the subsequent consequences for riparian predators remain poorly understood.

Tell me where you flow and I will tell you who you are: basin context shapes the insect fauna of small tributaries

Oikos, EarlyView.
The traditional view of river basins as linear corridors has led to numerous studies examining the effects of stream size on aquatic communities. However, similar‐sized streams may harbor distinct faunal assemblages depending on their spatial context within the basin. Headwater tributaries (HTs) that flow into small streams, in the periphery of basins,
