What is the impact of “liming” of streams and rivers on the abundance and diversity of fish and invertebrate populations? (systematic review)
What is the aim of the review? “Acid rain” and the associated acidification of waterways first became a widespread environmental concern in the 1970’s (Menz and Seip 2004). In the aquatic environment, acidification of waterways frequently causes changes in ecosystems including a reduction in fish and invertebrate numbers and diversity (Schindler et al 1985, Moiseenko […]

Are (re-) introductions an effective way of mitigating against plant extinctions? (systematic review)
What is the aim of the review? Re-introductions are considered by some conservation practitioners to be a controversial management option for mitigating threatened plant declines. The use of translocations (including re-introductions) has been criticised for the lack of monitoring and central recording, inappropriateness of the action due to genetic considerations, a lack of knowledge of […]

Have springs restoration projects in the southwestern United States been effective in restoring hydrology, geomorphology, and invertebrates and plant species composition comparable to natural springs with minimal anthropogenic disturbance? (systematic review)
What is the aim of the review? Springs, particularly those in arid regions, are vastly more complex, diverse, and productive than those in adjacent uplands; however, at a national and continental scale, springs are among our most threatened ecosystems. Springs are important resources because they are largely non-renewable ecological and cultural resources which provide habitats […]

Does seeding after severe forest fires in western USA mitigate negative impacts on soils and plant communities? (systematic review)
What is the aim of the review? Broadcast seeding is one of the most widely used post-wildfire emergency response treatments intended to reduce soil erosion, increase vegetative ground cover, and minimize establishment and spread of non-native plant species. However, seeding treatments can also have negative effects such as competition with recovering native plant communities and […]

Hotspots in a cold climate – are woodland key habitats biodiversity hotspots? (systematic review)
What is the aim of the review? To systematically collate and synthesize published and unpublished evidence originating from the Fennoscandia and Baltic countries as well as Russia, in order to address the following questions: “Are Woodland Key Habitats (WKH) biodiversity hotspots (i.e. do they have higher biodiversity qualities) compared to the surrounding production forests?” “Is […]

Do Landscape matrix features affect species movement? (systematic review)
Background Movement across the landscape is predicted to be important to species‟ regional population persistence and response to environmental change. Increased movement may increase the colonisation of newly-suitable patches, as well as recolonisation of patches after extinction events. Many biodiversity policies, such as the European Union Habitats Directive and the England Biodiversity Strategy, include recommendations […]

How do thinning and burning treatments in southwestern conifer forests in the United States affect wildlife distribution, abundance, and population performance? (systematic review)
What is the aim of the review? To examine whether thinning and burning treatments in conifer forests in the southwestern United States affect wildlife distribution, abundance, and population performance.
