Weak reproductive isolation and extensive gene flow between Mimulus glaucescens and M. guttatus in northern California
Abstract Barriers to reproduction are often how progress in speciation is measured. Nonetheless, an unresolved question concerns the extent to which reproductive barriers diminish gene flow between incipient species. The Sierra Nevada foothill endemic Mimulus glaucescens and the wides…
A biome-dependent distribution gradient of tree species range edges is strongly dictated by climate spatial heterogeneity
Understanding the causes of the arrest of species distributions has been a fundamental question in ecology and evolution. These questions are of particular interest for trees owing to their long lifespan and sessile nature. A surge in data availability evokes a macro-ecological analysis to determine…
Evolutionary ecology of an obligate and behaviorally manipulating insect- pathogenic fungus, Entomophthora muscae
Some insect-pathogenic fungi have evolved the ability to behaviorally manipulate their insect hosts. This has required the fungi to develop intricate mechanisms of infection, proliferation, and behavioral hijacking, which has led to speculation that behaviorally manipulating fungi must only infect a…

Can suitability indices predict plant growth in the invaded range? The case of Acacias species
IntroductionForestry in many parts of the world depends on exotic species, making this industry a source of invasions in some countries. Among others, plantations of the genus Pinus, Eucalyptus, Acacia, Populus, and Pseudotsuga underpin the forestry industry and are a vital component of many countri…
Prioritizing taxa for genetic reference database development to advance inland water conservation
Biodiversity loss has accelerated over the past century and freshwater species overall are among those experiencing greatest declines. Genetic resources have the potential to help evaluate the full magnitude of this loss and represent a key tool to effectively allocate conservation resources and mon…
Poleward amplification, seasonal rainfall and forest heterogeneity in the Miocene of the eastern USA
Paleoclimate reconstructions can provide a window into the environmental conditions in Earth history when atmospheric carbon dioxide concentrations were higher than today. In the eastern USA, paleoclimate reconstructions are sparse, because terrestrial sedimentary deposits are rare. Despite this, th…
Precipitation is the main axis of tropical plant phylogenetic turnover across space and time
Early natural historians—Comte de Buffon, von Humboldt, and De Candolle—established environment and geography as two principal axes determining the distribution of groups of organisms, laying the foundations for biogeography over the subsequent 200 years, yet the relative importance of these two axe…
Decreases over time in shannon diversity of land snails
With rising temperatures as a consequence of climate change, suitable habitats for land snails in the northern hemisphere may be shifting northwards. However, there is a lack of studies that explore the latitudinal effects that climate change has on land snails. Therefore, the aim was to see if ther…
Laurasian legacies in the Gondwanan tree fern order Cyatheales
AO_SCPLOWBSTRACTC_SCPLOWPresent-day geographic and phylogentic patterns often reflect the Gondwana-Laurasia separation and subsequent history of continental drift. However, some lineages show non-overlapping fossil distributions relative to extant species and in some cases extant Gondwanan lineages…
Assessment of current and future invasive plants in protected dune habitats of the Atlantic coastal region
Atlantic coastal dune systems in Europe are vulnerable to invasions by invasive plants, a continuous process driven by trends in urban plantings, escapes from gardens and range expansion of already established alien species. Early warning for invasive alien species and the sharing of practical exper…
Addressing Threats and Ecosystem Intactness to Enable Action for Extinct in the Wild Species
The species listed as Extinct in the Wild (EW) in the IUCN Red List of Threatened Species consist of 84 plants and animals that have been lost from their indigenous range. EW species are therefore restricted to ex situ conservation facilities and often have populations founded with few individuals. …
