Ecology Letters (2011) 14: 101–112 Abstract Biodiversity in agricultural landscapes can be increased with conversion of some production lands into ‘more‐natural’– unmanaged or extensively managed – lands. However, it remains unknown to what extent biodiversity enhanced by altering landscape pattern without reducing production. We propose a framework for this problem, considering separately compositional heterogeneity (the number and proportions different cover types) configurational spatial...
Agricultural landscape homogenization has detrimental effects on biodiversity and key ecosystem services. Increasing agricultural heterogeneity by increasing seminatural cover can help to mitigate loss. However, the amount of is generally low difficult increase in many intensively managed landscapes. We hypothesized that crop mosaic itself (hereafter "crop heterogeneity") also have positive biodiversity. In 8 contrasting regions Europe North America, we selected 435 landscapes along...
Predator Avoidance Strategy Selective pressures influencing bird migration can include availability of food, pressure from parasites and pathogens, predation risk. The importance the last these is revealed by McKinnon et al. (p. 326 ; see Perspective Gilg Yoccoz ), who present an experimental analysis benefits long-distance for reproduction in arctic-nesting birds. Measurements a controlled effect risk along 3350-kilometer north-south gradient across arctic Canada provides evidence that nest...
Agricultural intensification is one of the main causes for current biodiversity crisis. While reversing habitat loss on agricultural land challenging, increasing farmland configurational heterogeneity (higher field border density) and compositional crop diversity) has been proposed to counteract some loss. Here, we tested whether increased promote wild pollinators plant reproduction in 229 landscapes located four major western European regions. High-field density consistently bee abundance...
Increasing human population interacts with local and global environments to deplete biodiversity resources humans depend on, thus challenging societal values centered on growth relying technology mitigate environmental stress. Although the need address crisis, central conservation science, generated greener versions of paradigm, we fundamental shifts in that ensure transition from a growth-centered society one acknowledging biophysical limits well-being conservation. We discuss role science...
Abstract Aim The impact of multiple stressors on biodiversity is one the most pressing questions in ecology and conservation. Here we critically assess how often efficiently two main drivers global change have been simultaneously integrated into research, with aim providing practical solutions for better integration future. We focus climate (CC) land‐use (LUC) when studying changes species distributions. Location Global. Methods analysed peer‐reviewed literature effects CC LUC observed...
[1] The effects of changing ice and atmospheric conditions on the upwelling deep nutrient-laden waters biological productivity in coastal Beaufort Sea were quantified using a unique combination situ remote-sensing approaches. Repeated instances ablation during fall 2007 summer 2008 multiplied production algae, phytoplankton, zooplankton benthos by 2 to 6 fold. Strong wind forcing failed induce upward shifts stratified off shelf.
Abstract: In large parts of North America and Europe, deer overabundance threatens forest plant diversity. Few researchers have examined its effects on invertebrate assemblages. a natural experiment Haida Gwaii (British Columbia, Canada), where Sitka black‐tailed ( Odocoileus hemionus sitkensis ) were introduced, we compared islands with no deer, for fewer than 20 years, more 50 years. We sampled invertebrates in three habitat categories: edge vegetation below the browse line, interior...
Abstract: The devastation of island faunas by alien species has been instrumental in raising concerns about the global threat to biological diversity. Colonial nesting species, often restricted islands, have affected severely. Eradication introduced as a means alleviate problem is usually done with little or no understanding mechanisms governing interactions between and native species. Such an could help target management action. We analyzed how area, rock substrate, bird biology, presence...
Non‐consumptive effects of predators result from the cost responses to perceived risk. Prey modulate risk exposure through flexible habitat selection at multiple scales which, in interaction with landscape constraints, determines their use risky habitats. Identifying relative contributions constraints and is a critical first step towards mechanistic understanding non‐consumptive effects. Here, we provide an integrative multi‐scale study roe deer spatial variable hunting pressure along...
Abstract Increasing landscape heterogeneity by restoring semi‐natural elements to reverse farmland biodiversity declines is not always economically feasible or acceptable farmers due competition for land. We hypothesized that increasing the of crop mosaic itself, hereafter referred as heterogeneity, can have beneficial effects on within‐field plant diversity. Using a unique multi‐country dataset from cross‐continent collaborative project covering 1,451 agricultural fields within 432...
Abstract Aim To test whether the occupancy of shorebirds has changed in eastern Canadian Arctic, and these changes could indicate that shorebird distributions are shifting response to long‐term climate change. Location Foxe Basin Rasmussen Lowlands, Nunavut, Canada. Methods We used a unique set observations, made 25 years apart, using general linear models if there was relationship between species' their species temperature Index, simple version envelope. Results Changes density varied...
Since estimates of total species richness increase with sampling effort, methods to control for this effect need be tested and used. We present seven non‐parametric 12 accumulation curve that have been used recently in the ecological literature. To test their performance, we data from bird communities Queen Charlotte Islands, Canada. The performance each method was evaluated by calculating bias precision its against known richness. For our set, two Chao estimators were overall least biased...
We used the introduction of a generalist nest predator, red squirrel Tamiasciurus hudsonicus, and large herbivore, Sitka black‐tailed deer Odocoileus hemionus sitkensis, to islands Haida Gwaii (Queen Charlotte Islands, British Columbia, Canada) study how predator assemblage habitat quality structure influenced predation in forest birds. compared losses natural nests predators on with without squirrels. selected nine or 506 artificial put ground shrubs further analyse variation for predators....
Arctic breeding shorebirds travel thousands of kilometres between their wintering and grounds, yet the period over which they arrive begin to initiate nests spans only several weeks. We investigated role local conditions such as weather, snow cover predator abundance on timing arrival for at four sites in eastern Canadian arctic. Over 11 years, we monitored 12 species found 821 nests. Weather was highly variable course this study, date 50% varied by up three weeks years. In contrast, one...
