Journal ArticleDOI
Spatially autocorrelated sampling falsely inflates measures of accuracy for presence-only niche models
TL;DR: The goal of this study was to determine how spatially autocorrelated sampling affects measures of niche model accuracy when using subsets of a larger dataset for accuracy evaluation.
Journal ArticleDOI
Global synthesis of conservation studies reveals the importance of small habitat patches for biodiversity
Brendan A. Wintle,Heini Kujala,Amy L. Whitehead,Amy L. Whitehead,Alison Cameron,Sam Veloz,Aija S. Kukkala,Atte Moilanen,Ascelin Gordon,Pia E. Lentini,Natasha C. R. Cadenhead,Sarah A. Bekessy +11 more
TL;DR: A global synthesis of the relationship between the conservation value of habitat patches and their size and isolation, based on 31 systematic conservation planning studies across four continents found that small, isolated patches are inordinately important for biodiversity conservation.
Journal ArticleDOI
Vulnerability of biodiversity hotspots to global change
Céline Bellard,Camille Leclerc,Boris Leroy,Boris Leroy,Michel Bakkenes,Sam Veloz,Wilfried Thuiller,Franck Courchamp +7 more
TL;DR: In this article, the authors investigated whether hotspots are quantitatively and qualitatively threatened to the same order of magnitude by the combined effects of global changes, and they identified the Atlantic forest, Cape Floristic Region and Polynesia-Micronesia as particularly vulnerable to global changes.
Journal ArticleDOI
No-analog climates and shifting realized niches during the late quaternary: implications for 21st-century predictions by species distribution models
TL;DR: In this article, the authors compare the climate distributions for fossil-pollen data from 21 to 15 ka BP (relying on paleoclimate simulations) when communities and climates with no modern analog were common across North America to observed modern pollen assemblages.
Journal ArticleDOI

TL;DR: This work analyzed citizen science and satellite data to develop predictive models of bird populations and the availability of wetlands, which were used to determine temporal and spatial gaps in habitat during a vital stage of the annual migration and filled those gaps using a reverse auction marketplace.
