We present chironomid species assemblage data from 402 lakes across northern North
America, Greenland, Iceland, and Svalbard to inform interpretations of Holocene subfossil …

Understanding the effects of climate change on ecosystem structure and stability is
challenging, especially in high latitude regions that are predicted to experience the largest …

Anthropogenic activities have led to a global decline in biodiversity, and monitoring studies
indicate that both insect communities and wetland ecosystems are particularly affected …

Warming in the Arctic is predicted to change freshwater biodiversity through loss of unique
taxa and northward range expansion of lower latitude taxa. Detecting such changes requires …

Chironomid assemblages from the uppermost sediments of 435 lakes spanning northern
North America were compared to environmental parameters using direct gradient analysis …

The response of 443 chironomid species to water temperature was analyzed, with the aim of
defining their thermal optimum, tolerance limits and thermal habitat. The database included …

Abstract Knowledge of genetic and species-level diversity for freshwater invertebrates in the
Canadian Arctic is currently limited. Here, we sampled benthic and planktonic invertebrates …

Aim While we understand broad climate drivers of insect distributions throughout the Arctic,
less is known about the role of spatial processes in determining these relationships. As …

A multi-proxy paleolimnological survey was performed on 13 lakes in the Hudson Bay
Lowlands (HBL) of northern Ontario in order to provide a regional analysis of recent …

Abstract Chironomids (Diptera: Chironomidae) in northern lakes are especially sensitive to
climate change impacts. In addition, environmental factors other than direct temperature …
