Abstract Regulatory biodiversity trading (or “offsets”) is increasingly promoted as a way to enable both conservation and development while achieving “no net loss” or even “net gain” in biodiversity, but date has facilitated perpetuating loss. Ecologists seeking improved outcomes are developing better assessment tools recommending more rigorous restrictions enforcement. We explain why such recommendations overlook cannot correct key causes of failure protect biodiversity. Viable requires...
Agriculture dominates the planet. Yet it has many environmental costs that are unsustainable, especially as global food demand rises. Here, we evaluate ways in which different parts of world succeeding their attempts to resolve conflict between agriculture and wild nature. We envision coordinated action conserving land most sensitive agricultural activities policies internalise needed deliver a more sustainable future.
Abstract. Several properties have been suggested to be characteristic of ecotones, but their prevalence has rarely tested. We sampled five ecotones seek evidence on seven generalizations that are commonly made about ecotones: vegetational sharpness, physiognomic change, occurrence a spatial community mosaic, many exotic species, ecotonal mass effect, and species richness higher or lower than either side the ecotone. The were in sequence from scattered mangroves, through salt marsh,...

Abstract. Four contrasting ecotones were sampled to address three questions: (1) Are there ‘ecotonal’ species, (2) Do possess higher (or lower) species richness than the adjacent communities? and (3) exotic more likely occur in ecotones? One ecotone was edaphic, one apparently caused by a positive‐feedback switch, environmental/anthropogenic entirely anthropogenic. The exact position of each established from spatial change ordination scores. Ecotonal sense mainly restricted at site, present...
Abstract Aim To identify the bioclimatic niche of endangered Andean cat ( Leopardus jacobita ), one rarest and least known felids in world, by developing a species distribution model. Location South America, High Andes Patagonian steppe. Peru, Bolivia, Chile, Argentina. Methods We used 108 records to build models, 27 test them, applying Maxent algorithm sets uncorrelated variables from global databases, including elevation. based our biogeographical interpretations on examination predicted...
The field of biodiversity conservation is hampered by weak performance measurement and reporting standards (1). In other areas, such as the corporate world, considered bad practice, if not illegal (2, 3). Although various evaluation frameworks for programs have been suggested (4–7), few simple measures unbiased developed (8).
The Landscape Species Approach is a framework developed by the Wildlife Conservation Society for planning landscape-scale conservation based on suite of focal species. approach has so far been implemented at 12 terrestrial and two marine sites. We demonstrate using sites, Adirondack Park, USA, San Guillermo-Laguna Brava Landscape, Argentina. describe spatially explicit components, including steps to map attainable (Biological Landscape), current, future distribution Species, human activities...
Abstract New Zealand is home to 16 endemic species of Lepidium (Brassicaceae), including two considered have become extinct since European colonisation and an additional shared with Australia. Previous meiotic chromosome counts suggest at least some are high polyploids. A hybrid origin has been proposed for several them, African American implicated as parents. We generated amplicon sequence data 15 genes derived from targeted enrichment a selection Zealand, African, American, Australian...
Plant traits are influenced by herbivore diet selection, but little is known about how affected different types of herbivores. We related eight 27 subalpine shrub species in South Island, New Zealand, to damage these shrubs introduced red deer (Cervus elaphus) and native invertebrate herbivores using phylogenetically explicit modeling. Deer preferentially consumed that grew quickly, were low foliar tannins, or had high leaf area per unit mass. However, did not trade off against each other;...
Models of semiarid vegetation dynamics incorporating concepts equilibrium and stability have been largely replaced by nonequilibrium models in recent years. However, neither nor disequilibrium instability formally demonstrated. Most records are inadequate for conclusive tests. We tested at seven study sites six locations types, grazed grassland central Otago, New Zealand, using data collected twice annually over 5–13 yr. Some showed overall directional change composition time, but others...
