Species diversity of metazoan bulk samples can be rapidly assessed using Cytochrome c oxidase I (COI) metabarcoding. However, in cases where only degraded DNA is available, e.g. from poorly conserved museum specimens, eDNA filtered from water or gut content analyses,...

Exotic invasive species represent a major driver of the loss of biological diversity and services provided by ecosystems globally. An important source of species becoming invasive are the commercial afforestation projects using fast growing and adaptable exotic...

Microbes, with their vast metabolic capabilities and great adaptability, occupy almost every conceivable ecological niche on Earth. Thus, could they survive in the oligotrophic (i.e., nutrient poor) deionized (DI) water that we use for experiments? Observations...

Correct identification of forensically important insects, such as flies in the family Calliphoridae, is a crucial step for them to be used as evidence in legal investigations. Traditional identification based on morphology has been effective, but has some limitations...

Conservation biological control emphasizes the importance of vegetation other than the focal crop for providing natural enemies with refuge and shelter against disturbance. There is an unmet need for better methods to identify types of vegetation that are optimal...

Avian malaria parasites (genera Haemoproteus, Plasmodium, and Leucocytozoon) affect bird demography, distribution limits, and community structure, yet most bird communities and populations remain unsurveyed. We conducted a community-level survey of these vector-transmitted...

Environmental bulk samples often contain many taxa that vary several orders of magnitude in biomass. This can be problematic in DNA metabarcoding and metagenomic high-throughput sequencing approaches, as large specimens contribute disproportionately high amounts...

DNA extracted from feces (human and bovine) and water samples was used for the massive pyrosequencing of the hypervariable V3 region of the 16S rRNA gene, revealing 4296 operational taxonomic units (OTUs). The greatest diversity was observed in samples of cattle...

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...

We determined the environmental requirements leading to germination by three common species found during the summer rainy season in a peri-urban site where construction of a university campus was underway. In particular, we evaluated laboratory responses to low-temperature...

Amplicon based taxonomic analysis, which determines the presence of microbial taxa in different environments on the basis of marker gene annotations, often uses percentage identity as the main metric to determine sequence similarity against databases. These data...

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,...
