Tetrapod biodiversity today is great; over the past 400 Myr since vertebrates moved onto land, global tetrapod diversity has risen exponentially, punctuated by losses during major extinctions. There are links between the total global diversity of tetrapods and the diversity of their ecological roles, yet no one fully understands the interplay of these two aspects of biodiversity and a numerical...

The taxonomic status of Amphinemura palmeni, a rare stonefly from northern Fennoscandia, was re-evaluated in a morphological study combined with analyses of mitochondrial COI and nuclear 28S sequences. Taxon sampling included A. standfussi, with which A. palmeni has been confused, the Nearctic A. linda and seven other Amphinemura species. Amphinemura palmeni is confirmed as a valid species, and...

Diverse boards have been seen as providing impetus for initiating change. However, diversity may introduce conflict and impede decision making, which could hinder the ability of the firm to make strategic change, especially in times when firm performance is low. Integrating threat-rigidity theory and team diversity research, we examine how board gender diversity, firm performance, and the power...

Abstract: We investigates the effect of mobile speed, channel estimation rate, diversity order on performance degradation due to error floor in a mobile Single-Input-Multiple-Output (SIMO) wireless communication system. Each diversity channel is assumed to be fast Rayleigh fading process, which is modeled as a first order autoregressive process. Diversity channels are assumed to be independent ...

Much of the research in cross-cultural psychology is done using countries (national cultures) as main units of comparison, disregarding other important characteristics of the participants such as their ethnicity, language, religious or territorial affiliation. Thus, despite the fact that there exist clearly distinguishable sub-cultures within many countries or national cultures, they are often ...

Recognition of pathogens relies on families of proteins showing great diversity. Here we construct maximum entropy models of the sequence repertoire, building on recent experiments that provide a nearly exhaustive sampling of the IgM sequences in zebrafish. These models are based solely on pairwise correlations between residue positions but correctly capture the higher order statistical propert...

We provide information regarding the composition of the amphibian community at Yanayacu Biological Station, on the Amazonian slopes of the Andes of Ecuador, and describe a new species of Pristimantis that is referred to the P. myersi group. The new species is distinguished from other species of the group mainly by its color pattern, and by lacking ulnar and tarsal tubercles. The advertisement c...

One of the challenges that global software development teams face is the development of rich and meaningful interactions among members from different countries. Researchers and practitioners in the field are constantly looking for factors that may help organizations understand and mitigate the negative effects that nationality diversity may have on performance in global teams. This paper follow...

Why do some observations lead to broad generalizations whereas other observations do not have as much influence on people's beliefs? One principle of evaluating evidence is the diversity principle, which states that more diverse evidence should lead to stronger inferences than a narrow sample of evidence. For example, if you see someone repeatedly acting aggressively while giving lectures, you ...
