Unprecedented genomic diversity of RNA viruses in arthropods reveals the ancestry of negative-sense RNA viruses

open access: yeseLife, 2015
Although arthropods are important viral vectors, the biodiversity of arthropod viruses, as well as the role that arthropods have played in viral origins and evolution, is unclear.

Quantifying landscape‐level biodiversity change in an island ecosystem: a 50‐year assessment of shifts in the Hawaiian avian community

open access: yesEcography, EarlyView.
Hawaii has experienced profound declines in native avifauna alongside the introduction of numerous bird species. While site‐specific population studies are common, landscape‐level analyses of avian population dynamics are rare, particularly in island ecosystems. To address this gap, we used a density surface model to create a spatio‐temporal projection

Natural Occurrence in Venomous Arthropods of Antimicrobial Peptides Active against Protozoan Parasites

open access: yesToxins, 2019
Arthropoda is a phylum of invertebrates that has undergone remarkable evolutionary radiation, with a wide range of venomous animals. Arthropod venom is a complex mixture of molecules and a source of new compounds, including antimicrobial peptides (AMPs).

The First Myriapod Genome Sequence Reveals Conservative Arthropod Gene Content and Genome Organisation in the Centipede Strigamia maritima

open access: yesPLoS Biology, 2014
Myriapods (e.g., centipedes and millipedes) display a simple homonomous body plan relative to other arthropods. All members of the class are terrestrial, but they attained terrestriality independently of insects. Myriapoda is the only arthropod class not

Artificial Light Increases Local Predator Abundance, Predation Rates, and Herbivory. [PDF]

open access: yes, 2019
Human activity is rapidly increasing the radiance and geographic extent of artificial light at night (ALAN) leading to alterations in the development, behavior, and physiological state of many organisms.

A systematic review evaluating the performance of eDNA methods relative to conventional methods for biodiversity monitoring

open access: yesEcography, EarlyView.
The rapid adoption of environmental DNA (eDNA) methods has drastically changed biodiversity monitoring efforts. It is often claimed that eDNA methods are more sensitive and efficient than conventional biodiversity monitoring methods, but it is often unclear what metrics support this claim.

Unraveling the relationships between midge abundance and incidence, microbial communities, and soil and water properties in a protected natural tallgrass prairie

open access: yesParasites & Vectors
Background Biting midges (Culicoides spp.) are small blood-feeding flies (Diptera: Ceratopogonidae) that transmit numerous pathogens that impact animal and human health.

Extinct Pleistocene carnivores were diurnal and highly active

open access: yesEcography, EarlyView.
There is much contention over the causes and correlates of megafaunal extinctions at the end of the Pleistocene. A major role for human impact such as hunting has been discussed widely. If correct, the overkill hypothesis explains not only why large mammals in general were highly prone to extinction but suggests that extinction may have been selective ...
