Tree ferns on the move: patterns of movement and current introduction status of Cyatheales species around the worldNARA Subscribed
Tree ferns (order Cyatheales) have been moved from their native ranges for more than two centuries, and the number of species introduced to new countries has recently increased rapidly. However, no comprehensive global list of alien tree ferns exists. Botanical garden collections and the Global Biodiversity Information Facility database were examined, and a systematic literature review was conducted to collect information on t...
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has gained significant public health attention owing to its devastating effects on lives and livelihoods worldwide. Due to difficult access to vaccines in many developing countries and the inefficiency of vaccines in providing complete protection even with fully vaccinated persons, there remains the need for the development of novel drugs to combat the disease. This...
Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
Aim To determine the relationships between the functional trait composition of forest communities and environmental gradients across scales and biomes and the role of species relative abundances in these relationships. Location Global. Time period Recent. Major taxa studied Trees. Methods We integrated species abundance records from worldwide forest inventories and associated functional traits (wood density, specific leaf area...
Embryonic development is a continuum in vivo . Transcriptional analysis can separate established human embryonic stem cells (hESC) into at least four distinct developmental pluripotent stages, two naïve and two primed, early and late relative to the intact epiblast. In this study we primarily show that exposure of frozen human blastocysts to an inhibitor of checkpoint kinase 1 (CHK1) upon thaw greatly enhances establishment of...
As alien invasive species are a key driver of biodiversity loss, understanding patterns of rapidly changing global species compositions depends upon knowledge of invasive species population dynamics and trends at large scales. Within this context, the Ponto-Caspian region is among the most notable donor regions for aquatic invasive species in Europe. Using macroinvertebrate time series collected over 52 years (1968–2020) at 26...
Applying landscape metrics to species distribution model predictions to characterize internal range structure and associated changesNARA Subscribed
Distributional shifts in species ranges provide critical evidence of ecological responses to climate change. Assessments of climate‐driven changes typically focus on broad‐scale range shifts (e.g. poleward or upward), with ecological consequences at regional and local scales commonly overlooked. While these changes are informative for species presenting continuous geographic ranges, many species have discontinuous distribution...
Colonization of the Mediterranean basin by the vector biting midge species Culicoides imicola : an old storyNARA Subscribed
Understanding the demographic history and genetic make‐up of colonizing species is critical for inferring population sources and colonization routes. This is of main interest for designing accurate control measures in areas newly colonized by vector species of economically important pathogens. The biting midge Culicoides imicola is a major vector of orbiviruses to livestock. Historically, the distribution of this species was l...
