Urban streams are often managed in ways that contribute to societal inequities. Members of marginalized groups frequently exposed elevated flood risk and impaired water quality, with reduced access essential infrastructure greenspace within stream corridors. The freshwater science research community has traditionally argued for management improves ecological integrity, which can have the unintended consequence steering investments away from most degraded streams, low-income neighborhoods. We...
Traditionally, resistance and resilience are associated with good ecological health, often underpinning restoration goals. However, degraded ecosystems can also be highly resistant resilient, making difficult: communities become dominated by hyper-tolerant species, preventing recolonization resulting in low biodiversity poor ecosystem function. Using streams as a model, we undertook mesocosm experiment to test if community presence hindered biological recovery. We established 12 mesocosms,...
Abstract Ecological disturbances act as environmental filters by removing species with particular characteristics, resulting in community types associated different disturbance histories. However, studies to date on responses have neglected the potential for assemblages display responses. Using lotic invertebrate communities a study system, this investigated influence of composition response. We undertook 26-h stream channel experiment test how distinct (an undisturbed spring community,...
Abstract The generalizable functional attributes of organisms (traits) relate strongly to their environment across multiple levels biological organization, making trait‐based approaches a powerful mechanistic framework understand species distributions and community composition in relation environmental change. To investigate how wide range stressor types shape stream macroinvertebrate communities, we conducted an integrative analysis using taxon trait information drying, flooding,...
River restoration projects often focus on water quality and riparian vegetation, assuming this will result in direct improvements to ecological health. However, successful recovery of aquatic communities likely requires additional steps targeting habitat beneath the surface. We trialled addition simple, instream units as a practicable short-term tool macroinvertebrate communities. Habitat were built from readily available, biodegradable materials. They deployed at three sites around Auckland...
