Fundamentally, beta diversity is a measure of species turnover across time or space. In practice, it is sometimes unclear exactly what aspect of beta diversity that is implied in studies. For instance, a trend in ’spatial beta diversity’ can be used to refer to...

Ligia isopods are conspicuous inhabitants of rocky intertidal habitats exhibiting several biological traits that severely limit their dispersal potential. Their presence in patchy habitats and low vagility may lead to long term isolation, allopatric isolation and...

Premise of the Study. The internal transcribed spacer (ITS) region is situated between 18S and 26S in a polycistronic rRNA precursor transcript. It had been proved to be the most commonly sequenced region across plant species to resolve phylogenetic relationships...

Species diversity of metazoan bulk samples can be rapidly assessed using cytochrome c oxidase I (COI) metabarcoding. However, in some applications often only degraded DNA is available, e.g. from poorly conserved museum specimens, environmental DNA (eDNA) filtered...

The Geraniales Phylogeny Poster (GPP) depicts the phylogenetic relationships between the five families of the order recognized here: Geraniaceae, Hypseocharitaceae, Vivianiaceae, Francoaceae, and Melianthaceae – down to the genus level – based on past and most...

Background: Metabarcoding studies allow a wide variety of taxa to be analysed simultaneously in a fraction of the time taken by morphological identification, but currently metabarcoding studies must rely on sequence similarity-based methodologies to delimit operational...

Avian malaria and related haemosporidian parasites (genera Haemoproteus, Plasmodium, and Leucocytozoon) affect bird demography, species range limits, and community structure, yet they remain unsurveyed in most bird communities and populations. We conducted a community-level...

Patagonia, a cul-de-sac for the continental dispersal of Homo sapiens into the Americas, has been extensively analyzed by archaeologists and bioanthropologists. Despite its deep and rich archaeological record, the genetic make up of its pre-contact inhabitants...

Recovery planning is an essential part of implementing the U.S. Endangered Species Act (ESA), but conservationists and government agencies recognize challenges with the current planning process. Common criticisms are that too many species lack recovery plans, plans...

Background. Establishment success of non-native species can be influenced by interactions with native competitors and novel enemies. Magnitude of interactions between species is mediated by traits, e.g. reflecting competitive strength or defence mechanisms. We...
