Data from: Evolutionary patterns in the geographic range size of Atlantic Forest plants
Species' geographic range size is arguably the single most important predictor of vulnerability to extinction and a key metric in ecology. Despite this, patterns of specific variation in range size and their underlying reasons are still poorly understood. For example, hypotheses on how evolutionary history affects range size have scarcely been tested. To address these questions, we focused on Brazil's Atlantic Forest flora, one of the most species-rich in the world, relatively well-known and highly threatened. We investigated whether and how lineages' diversification rate, number of species and age are associated with species' geographic range size. We estimated the extent of occurrence and area of occupancy of each of 13,283 plant species native to the Atlantic Forest region based on over 500,000 unique records. We used phylogenetic least squares and logistic regressions to analyze how the predictors affect the geographic range size. On average, the higher the diversification rate and number of species in the lineage, the smaller the species range size and the higher the proportion of species with vulnerably small range size. Lineage age showed no clear effect on average range size. The results support our expectations that dynamics of diversification and taxonomic richness considerably affect the species range size. Finally, this work reveals poorly known patterns of range size variation and some of the mechanisms driving variation in range size and vulnerability to extinction.
Data from: Topographic ruggedness and rainfall mediate geographic range contraction of a threatened marsupial predator
Aim: Species range contractions are increasingly common globally. The niche reduction hypothesis posits that geographic range contractions are often patterned across space owing to heterogeneity in threat impacts and tolerance. We applied the niche reduction hypothesis to the decline of a threatened marsupial predator across northern Australia, the northern quoll (Dasyurus hallucatus). Location: Northern Australia Methods: We assembled a data base containing 3178 historic and contemporary records for northern quolls across the extent of their distribution dating between 1770 and 2019. Based on these records, we estimated changes in the geographic range of the northern quoll using α-hulls across four main populations. We then examined how range contractions related to factors likely to mediate the exposure, susceptibility, or tolerance of northern quolls to threats. Result: The extent of range contractions showed an east-west gradient, most likely reflecting the timing of spread of introduced cane toads (Rhinella marina). There were clear changes in environmental characteristics within the contemporary compared to the historic geographic range, with the most substantial occurring in populations that have suffered the greatest range contractions. The contemporary range is comprised of higher quality habitats (measured using environmental niche models), characterized by higher topographical ruggedness and annual rainfall, and reduced distance to water, compared to the historic range. Main conclusions: Changes to range and niche likely reflect the capacity of complex habitats to ameliorate threats (namely predation and altered fire regimes), and access to resources that increase threat tolerance. This study highlights the multivariate nature of ecological refuges, and the importance of high-quality habitats for the persistence of species exposed to multiple threats. Our methods provide a useful framework which can be applied across taxa in providing valuable insight to management.
