Abstract
A substantial number of potential underground carbon storage reservoirs exist in regions that contain permafrost (continuously frozen layers of the subsurface), such as in the Alaskan North Slope. The extent and depth of these permafrost layers are changing globally at a rapid pace [...] Read more.
A substantial number of potential underground carbon storage reservoirs exist in regions that contain permafrost (continuously frozen layers of the subsurface), such as in the Alaskan North Slope. The extent and depth of these permafrost layers are changing globally at a rapid pace on the geologic timescale, which warrants continued research and observation. In order to prepare for successful carbon sequestration projects in these regions, in this work, we investigate the outcome from the potential scenario of carbon dioxide encountering the permafrost at depth. This article reviews currently available literature pertaining to the characteristics of permafrost for carbon storage in the case of the injection of carbon dioxide into deep onshore underground reservoirs. This study compares research showing evidence of both the flow of carbon dioxide gas through permafrost and the storage of carbon dioxide gas by permafrost. The findings suggest more research is needed, and several future research areas are outlined in this work. Full article

Invasive alien species (IAS) can cause the extinction of a taxon. However, debate continues over the significance of IAS as drivers of extinction globally, the level of threat they pose to endangered species, and whether conservation efforts against IAS should take priority over other factors, such as habitat loss or climate change. We provide new insights from the IUCN Red List, focusing on species classified as extinct or extinct in the wild that are linked exclusively to IAS. Many extinction events are also caused by multiple synergistic threats, including IAS, but the relative contributions of these threats remain uncertain. We suggest using Structural Equation Models (SEMs) to tease out the effects of IAS and other interacting factors on threatened species, to better understand the role of IAS in potential extinctions.

Globally, timber production continues to dominate multiple-use forest management despite evidence from many managed landscapes that ecological integrity and biodiversity are not being sustained under that land-use model. This includes Algonquin Park where two centuries of road building, logging, and aggregate mining have contributed to a ~82% (6200 km2) reduction in unlogged, roadless (>1 km from roads) habitat at a mean decline rate of 32 km2/yr. There are at least ~5500 km of roads that fragment Algonquin Park into 732 roadless habitats covering 18% of the Park’s area. Almost 40,000 ha of these habitats are unprotected from logging. Decline of roadless habitat in Algonquin has contributed to the impairment of ecological integrity and decline of at least 34 species across all trophic levels, including at least 17 species-at-risk. Restoring the natural Algonquin Park landscape would result in job losses; however, data suggest that new recreation–tourism and research–education jobs would help to offset these losses. A new agency could build on existing infrastructure to monitor, research, educate about, maintain, and restore biodiversity and recreational resources in the greater Algonquin Park Region, with the park as the central hub. Restoration could be focused on roadless areas as an “integrative” indicator of ecological integrity. Full article
