Marine species and ecosystems are widely affected by anthropogenic stressors, ranging from pollution and fishing to climate change. Comprehensive assessments of how species and ecosystems are impacted by anthropogenic stressors are critical for guiding conservation and management investments. Previous global risk or vulnerability assessments have f...
Article
The growth and survival of individual trees determine the physical structure of a forest with important consequences for forest function. However, given the diversity of tree species and forest biomes, quantifying the multitude of demographic strategies within and across forests and the way that they translate into forest structure and function rem...
Article
Species traits have much to offer conservation science. However, the selection and application of trait data in conservation requires rigor to avoid perverse or unexpected outcomes. To guide trait use, we review how traits are applied along the conservation continuum: the progression of conservation actions from assessing risk, to designing and pri...

Arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) associations are critical for host-tree performance. However, how mycorrhizal associations correlate with the latitudinal tree beta-diversity remains untested. Using a global dataset of 45 forest plots representing 2,804,270 trees across 3840 species, we test how AM and EcM trees contribute to t...
Article
Full-text available
When Darwin visited the Galapagos archipelago, he observed that, in spite of the islands’ physical similarity, members of species that had dispersed to them recently were beginning to diverge from each other. He postulated that these divergences must have resulted primarily from interactions with sets of other species that had also diverged across...
Article
Full-text available
In 2010, Parties to the Convention on Biological Diversity (CBD) adopted the Strategic Plan for Biodiversity 2011-2020 to address the loss and degradation of nature. Subsequently, most biodiversity indicators continued to decline. Nevertheless , conservation actions can make a positive difference for biodiversity. The emerging Post-2020 Global Biod...
Article
Full-text available
Species that cannot adapt or keep pace with a changing climate are likely to need human intervention to shift to more suitable climates. While hundreds of articles mention using translocation as a climate-change adaptation tool, in practice, assisted migration as a conservation action remains rare, especially for animals. This is likely due to conc...
Preprint
The Global Strategy for Plant Conservation (GSPC) ambitiously calls for an assessment of extinction risk for all recognised plant taxa by 2020. It is now clear that this target will not be met in the short-term; only 21-26% of known plant species have been assessed - a monumental shortfall in anticipated knowledge. Yet the need for risk assessments...

Every year, more people are killed defending the environment than are soldiers from the United Kingdom and Australia on overseas deployments in war zones combined. During the last 15 years, the number of both deaths of environmental defenders, and the countries where they occur, have increased. Recorded deaths have increased from two per week to fo...
Article
Full-text available
Climate change poses significant challenges to the long-term management of threatened species. Pre-emptive assessments of the capacity for threatened species to adapt to climate change are essential for choosing appropriate management actions that minimise extinction risk. Here, we use species traits and range metrics linked to ecological performan...
Article

Aim Many conservation efforts now focus on mitigating biodiversity loss due to climate change. While a focus on impacts from mean, long‐term changes in climate is warranted, the vast majority of conservation plans largely ignore another key factor of climate change—changes in the frequency and intensity of extreme weather and climate events. A typo...
Article
Reliable assessment of forest structural types (FSTs) aids sustainable forest management. We developed a methodology for the identification of FSTs using airborne laser scanning (ALS), and demonstrate its generality by applying it to forests from Boreal, Mediterranean and Atlantic biogeographical regions. First, hierarchal clustering analysis (HCA)...
Article
Full-text available
Few assessments of species vulnerability to climate change used to inform conservation management consider the intrinsic traits that shape species’ capacity to respond to climate change. This omission is problematic as it may result in management actions that are not optimised for the long-term persistence of species as climates shift. We present a...
Article
Full-text available
Inadequate information on the geographical distribution of biodiversity hampers decision-making for conservation. Major efforts are underway to fill knowledge gaps, but there are increasing concerns that publishing the locations of species is dangerous, particularly for species at risk of exploitation. While we recognize that well-informed control...

Early project-level initiatives of ‘reducing emissions from deforestation and forest degradation’ (REDD+) have left a negative impression among many forest-dependent peoples (FDP) across the tropics. As countries move towards national-level implementation and results-based payments, it is timely to analyze the effects of ‘national REDD+’ on FDP. We...
Article
Full-text available
There is growing evidence that global climate change is significantly altering forest ecosystems, and will continue to do so in the future. Changes in mean climate and climate extremes such as drought, storms, cyclones and wildfires can fundamentally alter species distribution, composition, phenology, and forest structure. This study reviewed the a...
Article
Effective leaders are critical in determining successful outcomes of conservation programs. As the business and economic leadership literature shows, awareness around cultural differences in leadership attributes is important for positive project outcomes set in inter-cultural contexts. We conducted a systematic review of the literature to understa...

Species' response to climate change is already occurring and managers require scenario planning with tangible actions for effective conservation. We address this need by examining the impact of projected changes in maximum temperature and sea level rise (SLR), on the future suitability of current nesting sites for two globally endangered turtle spe...
Article
Predicting the consequences of climate change for biodiversity is critical to conservation efforts. Extensive range losses have been predicted for thousands of individual species, but less is known about how climate change might impact whole clades and landscape-scale patterns of biodiversity. Here, we show that climate change scenarios imply signi...
Article
Understanding climate change impacts on species is vital for correctly estimating their extinction risk and choosing appropriate conservation actions. We perceive four common challenges that hamper conservation planning for species affected by climate change: (i) only considering climate exposure in assessments of vulnerability to climate change, i...

Article
Full-text available
An age-old conflict around a seemingly simple question has resurfaced: why do we conserve nature? Contention around this issue has come and gone many times, but in the past several years we believe that it has reappeared as an increasingly acrimonious debate between, in essence, those who argue that nature should be protected for its own sake (intr...
