Molecular markers delimit cryptic species in Ceratocystis sensu stricto

open access: yesMycological progress, 2014
Ceratocystis sensu stricto is a genus of closely related fungi that are mostly plant pathogens. Morphological variation between species in this genus is limited, and species delineation is strongly reliant on phylogenetic inference.

A test of the abundant‐center hypothesis for stream fishes

open access: yesEcography, EarlyView.
The abundant‐center hypothesis (ACH) provides a conceptual model for predicting range‐wide distributions of species abundance, suggesting that abundance peaks in the center of the geographic range and declines towards range edges. Empirical studies testing the ACH and its subsequent derivations predominantly occurred in terrestrial systems and reported

Synoptic overview of Acacia sensu lato (Leguminosae: Mimosoideae) in East and Southeast Asia

open access: yes, 2015
Recent research shows that the formerly broadly circumscribed, pantropical genus Acacia Mill. (Leguminosae: Mimosoideae) is polyphyletic and should be treated as comprising at least five genera, namely, Acacia Mill.

Helicobacter heilmannii sensu lato: an overview of the infection in humans.

open access: yesWorld Journal of Gastroenterology, 2014
Helicobacter heilmannii sensu lato (H. heilmannii s.l.) is a group of gastric non-Helicobacter pylori Helicobacter species that are morphologically indistinguishable from each other. H. heilmannii s.l.

Freshwater fish functional diversity shows diverse responses to human activities, but consistently declines in the tropics

open access: yesEcography, EarlyView.
Freshwater environments are intertwined with human activities and the consequence has been environmental degradation and biodiversity loss. Fish provide key ecological and economic benefits, and fish abundance and diversity can be affected by human activities resulting in functional diversity (FD) changes that might scale up to ecosystem impacts ...

Using spatial capture–recapture methods to estimate long‐term spatiotemporal variation of a wide‐ranging marine species

open access: yesEcography, EarlyView.
Determining population status to inform mitigation of anthropogenic threats requires statistical approaches that investigate spatial and temporal variation. In the face of climate change it is increasingly important to differentiate between changes in population size and redistributions of populations.

Draft Genome Sequence of Colletotrichum acutatum Sensu Lato (Colletotrichum fioriniae)

open access: yesGenome Announcements, 2014
In addition to its economic impact, Colletotrichum acutatum sensu lato is an interesting model for molecular investigations due to the diversity of host-determined specialization and reproductive lifestyles within the species complex.

Integrating climate change, biological invasions, and infectious wildlife diseases

open access: yesFrontiers in Ecology and the Environment, EarlyView.
Climate change is likely to affect infectious diseases that are facilitated by biological invasions, with repercussions for wildlife conservation and zoonotic risks. Current invasion management and policy are underprepared for the future risks associated with such invasion‐related wildlife diseases. By considering evidence from bioclimatology, invasion
