Aim Phylogenetic community structures have traditionally been interpreted through the lens of niche processes, such as environmental filtering and interspecific competition. However, these structures have been continuously shaped over evolutionary time by biogeographical dynamics, a process that is often overlooked. Here, we disentangled the influence of speciation and dispersal on spatial phylogenetic structures using neutral...

Correlation of climate and infectious disease has been noted for millennia and recorded in the writings of Hippocrates. Given recent technological advances in both pathogen detection and monitoring of infectious diseases in a time of climate change, a detailed study of their link is now possible. In the aquatic environment, climate change has had an impact on ocean, estuary, and freshwater ecosystems that coincides with increa...

The last 12 months have provided further evidence of the potential for cascading ecological and socio-political crises that were warned of 12 months ago. Then a consensus statement from the Regional Action on Climate Change Symposium warned: “the Earth’s climatic, ecological, and human systems are converging towards a crisis that threatens to engulf global civilization within the lifetimes of children now living.” Since then,...

Summary Vibrio spp . thrive in warm water and moderate salinity, and they are associated with aquatic invertebrates, notably crustaceans and zooplankton. At least 12 Vibrio spp. are known to cause infection in humans, and Vibrio cholerae is well documented as the etiological agent of pandemic cholera. Pathogenic non‐cholera Vibrio spp ., e.g., Vibrio parahaemolyticus and Vibrio vulnificus , cause gastroenteritis, septicemia, a...

Understanding the causes of spatial variation in species richness is a major research focus of biogeography and macroecology. Gridded environmental data and species richness maps have been used in increasingly sophisticated curve‐fitting analyses, but these methods have not brought us much closer to a mechanistic understanding of the patterns. During the past two decades, macroecologists have successfully addressed technical p...

Summary In this study, we report the presence of the SXT element and Class I integron in Vibrio cholerae non‐O1, non‐O139 strains isolated from Varanasi, India. Isolates were resistant to cotrimoxazole, trimethoprim and/or streptomycin, furazolidone and ampicillin. None contained plasmids. Polymerase chain reaction (PCR) and DNA sequencing revealed the presence of antibiotic resistance gene cassettes, aadA1 , aadA2 , aadA5 and...

A 14 year integration with a regional atmospheric model has been used to determine the near‐surface climatological wind field over the Antarctic ice sheet at a horizontal grid spacing of 55 km. Previous maps of the near‐surface wind field were generally based on models ignoring the large‐scale pressure‐gradient forcing term in the momentum equation. Presently, state‐of‐the‐art atmospheric models include all pressure‐gradient f...
