Trace Metals in Aquatic Invertebrates
, 2011 This chapter addresses the interpretation of accumulated trace metal concentrations in one component of the biota—in this case aquatic invertebrates. Aquatic invertebrates represent key members of the biota of habitats particularly at risk from toxic metal contamination, such as fresh-waters and estuaries receiving metal-laden effluents from mining ...

Journal of Quaternary Science, EarlyView.ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Ecosystem Health and SustainabilityInland wetlands of arid and semiarid regions are unique ecosystems shaped by pronounced salinity gradients that strongly regulate biodiversity patterns. However, comparative studies of multiple aquatic taxa along the salinity gradient remain limited.

Limnology and Oceanography: Methods, EarlyView.Abstract Carbon (δ13C) and nitrogen (δ15N) stable isotope ratios allow the reconstruction of food webs, provided that all trophic levels are properly characterized. In freshwater ecosystems, small‐bodied invertebrates often occupy central positions in food webs, with whole‐body samples commonly used for their stable isotope analysis, due to ...

Oikos, EarlyView.Ecosystem engineers are crucial to the development of coastal ecosystem communities and functions. However, a better understanding of how environmental stressors affect ecosystem engineering and thereby influence communities and ecosystem dynamics is needed. We conducted an in situ experiment in a blue mussel Mytilus spp.

Warming modifies trophic impacts of invading shrimp with impact varying among primary producers
Oikos, EarlyView.Environmental change drivers, such as climate change and species invasions, can disrupt biological networks and weaken ecosystem stability. Acting together, these drivers may interact and alter the effects on the ecosystem. However, few studies have examined the interactive effects of climate change and species invasions, particularly in aquatic ...

The dynamics of wild and alternative meat consumption across Gabon, Central Africa
People and Nature, EarlyView.Abstract Long‐term overharvesting of wild animals for their meat threatens wildlife and the people dependent on wild animal meat for their diets and incomes. Interventions to reduce wild meat consumption must be built upon a complete understanding of the roles of wild meat and its alternatives within food systems.
