BERA News Fall 2022
Resource
Understanding how birds respond to landscape disturbance is key to effective restoration. Two studies used non-invasive microphone arrays to determine the exact locations of singing individuals in the...
BERA News Spring 2022
Resource
Mounding is a common restoration technique designed to improve microsite conditions for planted seedlings in wetlands. There are a variety of strategies for constructing mounds, though, and how mounds...
Caribou and Reindeer Migrations in the Changing Arctic
Resource
Caribou and reindeer, Rangifer tarandus, are the most numerous and socio-ecologically important terrestrial species in the Arctic. Their migrations are directly and indirectly affected by the seasonal...
Continental Synchrony and Local Responses: Climatic Effects on Spatiotemporal Patterns of Calving in a Social Ungulate
Resource
Warming temperatures and advancing spring are affecting annual snow and ice cycles, as well as plant phenology, across the Arctic and boreal regions. These changes may be linked to observed population...
Critical Summer Foraging Tradeoffs in a Subarctic Ungulate
Resource
Summer diets are crucial for large herbivores in the subarctic and are affected by weather, harassment from insects and a variety of environmental changes linked to climate. Yet, understanding...
Increasing Fire Frequency and Severity Will Increase Habitat Loss for a Boreal Forest Indicator Species
Resource
Climate change will lead to more frequent and more severe fires in some areas of boreal forests, affecting the distribution and availability of late-successional forest communities. These forest...
Seasonal Patterns of Spatial Fidelity and Temporal Consistency in the Distribution and Movements of a Migratory Ungulate
Resource
How animals use their range can have physiological, ecological, and demographic repercussions, as well as impact management decisions, species conservation, and human society. Fidelity, the...
Tactical Departures and Strategic Arrivals: Divergent Effects of Climate and Weather on Caribou Spring Migrations
Resource
A 2019 academic paper that looks at factors affecting caribou migration timing and speed. The paper concludes that later arrival at calving grounds might indicate that females are in worse condition...
The Boreal Ecosystem Recovery and Assessment (BERA)
Project
Organization:
The boreal region of Alberta contains extensive disturbances from natural resource extraction. Roads, well pads, seismic lines (petroleum-exploration corridors), forest-harvest areas, and other...
The Boreal-Arctic Wetland and Lake Dataset
Resource
Here we present the Boreal–Arctic Wetland and Lake Dataset (BAWLD), a land cover dataset based on an expert assessment, extrapolated using random forest modelling from available spatial datasets of...
The Edge 2022 (BERA Systhesis)
Resource
The central goal of the Boreal Ecosystem Recovery and Assessment (BERA) program is to understand the effects of industrial disturbance on natural ecosystem dynamics, and to develop strategies for...
The Edge: The BERA Program 2024 Synthesis Report
Resource
The 2024 issue of The Edge summarizes the following key findings: Plan A better understanding of passive recovery trajectories will help guide restoration planning LiDAR is a powerful planning tool...
The Role of Weather and Long-Term Prey Dynamics as Drivers of Wolf Population Dynamics in a Multi-Prey System
Resource
As climate change accelerates in northern latitudes, there is an increasing need to understand the role of climate in influencing predator-prey systems. We investigated wolf population dynamics and...
Untangling Effects of Human Disturbance and Natural Factors on Mortality Risk of Migratory Caribou
Resource
Abstract Human disturbances are rapidly increasing in northern and Arctic regions, raising concerns about the recovery and persistence of declining caribou ( Rangifer tarandus) populations. Yet, the...
