Human impacts on the Earth’s biosphere are driving the global biodiversity crisis. Governments are preparing to agree on a set of actions intended to halt the loss of biodiversity and put it on a path to recovery by 2050. We provide evidence that the proposed actions can bend the curve for biodiversity, but only if these actions are implemented urg...

Genetic diversity is crucial for conservation biology and for understanding evolutionary processes. Oceanic islands harbor a unique biota and high endemism, with populations frequently facing detrimental genetic processes (e.g. drift, bottlenecks). Human activities like habitat transformation further increase extinction risk of insular biota. Mamma...

Landscape genetics aims to understand how the landscape relates to microevolutionary processes, by estimating gene flow and connectivity, identifying genetic discontinuities and environmental patterns associated with genetic structure and adaptation. The black-eared mouse, Peromyscus melanotis, is a quasi-endemic rodent restricted to temperate fore...

Integrating ancient fossil DNA with modern genetic samples is aiding in advancing the fields of ecology and biogeography. However, wide gaps in the fossil record still remain throughout the tropics, while genetic and genomic datasets from tiny (<50 mg) ancient tropical fossils recovered from small mass species (<100 g) are particularly scarce. We s...

Conservation efforts should target the few remaining areas of the world that represent outstanding examples of ecological integrity and aim to restore ecological integrity to a much broader area of the world with intact habitat and minimal species loss while this is still possible. There have been many assessments of “intactness” in recent years bu...

• Long‐term evolutionary history and demographic processes shape current patterns of genetic variation in natural populations. Genetic diversity is of prime importance for the long‐term survival of species, especially those threatened or endangered, which can be lost in a few generations and can take hundreds to recover. Notably, turtles are among...

Defining conservation units is an important step in species management and requires interpretation of the genetic diversity and ecological function of the taxon being considered. We used the endemic Cuban Rock Iguanas (Cyclura nubila nubila) as a model to highlight this challenge and examined patterns of its intraspecific genetic diversity across C...

The different life forms on Earth are distributed in a non-random fashion, resulting from a diverse array of events during the Earth’s history that has governed the spatial and temporal distribution of species. Anthropogenic activities have produced changes in global climate and land use that have affected, and will continue to impact, the distribu...

Since the term was coined in 2003, landscape genetics (LG) is a field that integrates population genetics, landscape ecology, and spatial analytical techniques to quantify the effects of landscape on microevolutionary processes. Despite the growing interest in LG, there is little knowledge about the trends in LG research for America in general and...

Genetic variation is fundamental to population fitness and adaptation to environmental change. Human activities are driving declines in many wild populations and could have similar effects on genetic variation. Despite the importance of estimating such declines, no global estimate of the magnitude of ongoing genetic variation loss has been conducte...

Genetic variation underpins population fitness and adaptive potential. Thus it plays a key role in any species' probability of long-term persistence, particularly under global climate change. Genetic variation can be lost in a single generation but its replenishment may take hundreds of generations. For that reason safeguarding genetic variation is...

Gene flow in animals is limited or facilitated by different features within the landscape matrix they inhabit. The landscape representation in landscape genetics (LG) is traditionally modeled as resistance surfaces (RS), where novel optimization approaches are needed for assigning resistance values that adequately avoid subjectivity. Also, desert e...

Interspecific hybridization can lead to adaptation and speciation, especially in the context of recent radiations. The emblematic Crocodylus (true crocodiles) is the most broadly distributed, ecologically diverse, and species-rich crocodylian genus. Nonetheless, their within-species evolutionary processes are poorly resolved mainly due to their pot...

Intraspecific variation is a major component of biodiversity, yet it has received relatively little attention from governmental and non-governmental organizations, especially with regard to conservation plans and the management of wild species. This omission is ill-advised because phenotypic and genetic variation within and among populations can ha...

Hybrid zones represent natural laboratories to study gene flow, divergence and the nature of species boundaries between closely related taxa. We evaluated the level and extent of hybridization between Crocodylus moreletii and C. acutus using genetic and morphological data on 300 crocodiles from 65 localities. To our knowledge, this is the first gen...

Most genetic studies of Holocene fauna have been performed with ancient samples from dry and cold regions, in which preservation of fossils is facilitated and molecular damage is reduced. Ancient DNA work from tropical regions has been precluded owing to factors that limit DNA preservation (e.g. temperature, hydrolytic damage). We analysed ancient...
