An overdominant mutation in the elongation factor 1-alpha (EF1A) gene in the sea star Pisaster ochraceus has shown itself to mediate tolerance to "sea star wasting disease", a pandemic that has significantly reduced sea star populations on the Pacific coast of...

Background. Species that transform habitats in ways that influence other species are known as Ecosystem Engineers. While the impacts of many engineers have been well described, how the impacts of engineers vary along or even alter environmental gradients remains...

Much of Earth’s biodiversity is at the mercy of currents and physical turnover. Residence time (τ) is the average time that particles spend in a system and is estimated from the ratio of volume to flow rate. Here, we present a framework for how τ influences biodiversity...

The use of functional traits has increased exponentially in ecology, particularly in attempting to understand plant strategies and ecosystem functioning. This popularity has led to many proposed definitions of functional traits, which in turn has informed recommendations...

Errors in botanical surveying are a common problem. The presence of a species is easily overlooked, leading to false-absences; while misidentifications and other mistakes lead to false-positive observations. While it is common knowledge that these errors occur,...

Radio telemetry is a common tool to monitor animals in many ecosystems. Radio telemetry, or radio tracking, typically uses a tag or collar with a radio transmitter attached to an animal that is monitored by researchers with a receiver. This technique is used for...

Patterns underpin ecological theories and paradigms. While over a dozen ecological patterns are considered to be classic or even law-like, most are divided among non-overlapping theories and subfields. As a result, ecology lacks a holistic understanding for how...

With the emergence of Next Generation Sequencing, major advances were made with regard to identifying viruses in natural environments. However, bioinformatical research on viruses is still limited because of the low amounts of viral DNA that can be obtained for...

Crop domestication is an adaptive process that transforms a wild plant into a domesticated species that can reared and maintained for human use. Though there are hundreds of thousands of flowering plant species, only a small fraction has ever been domesticated....
