Contextually conspicuous species are more likely to be venomous: Habitat‐dependent aposematic colouration found throughout snakes

Journal of Animal Ecology, EarlyView.
Conspicuous colouration signals venomous nature throughout snakes. Abstract Many animals use conspicuous colours to advertise their unprofitability to potential predators, a phenomenon known as aposematism. For example, conspicuous banded patterns in snakes are often highlighted as aposematic signalling of their venomous nature.

Phylogenetic relatedness, functional traits, and spatial scale determine herbivore co-occurrence in a subtropical forest

, 2022
The mechanisms driving species co-occurrence are varied and include biotic interactions, abiotic factors, and scale-dependent processes. Based on a comprehensive dataset of lepidopteran herbivores recorded from a large-scale forest biodiversity ...

Host‐mediated filtering and interspecific associations structure strongyle parasite communities in Sable Island horses

Journal of Animal Ecology, EarlyView.
Using individual‐level nemabiome metabarcoding of 3147 samples from 916 horses on Sable Island over 10 years, we generate the largest dataset of its kind to date. This unprecedented scale enables a rare test of the processes structuring parasite communities in a natural system, revealing dominant host‐mediated filtering and predominantly positive ...

Analysis of two genomic variants of orang-utan hepadnavirus and their relationship to other primate hepatitis B-like viruses [PDF]

, 2001
We recently described orang-utan hepadnavirus (OuHV) (Warren et al., Journal of Virology, 73, 7860–7865, 1999). Phylogenetic analyses indicated that the various isolates of OuHV can be divided into two genomic variants.

And then there was us Et puis nous sommes apparus

Journal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,

Data from: Resident-invader phylogenetic relatedness, not resident phylogenetic diversity, controls community invasibility

, 2015
A central goal of invasion biology is to elucidate mechanisms regulating community invasibility. Darwin’s naturalization hypothesis, one of the oldest hypotheses in invasion biology, emphasizes the importance of phylogenetic relatedness (PR) between ...

Characterization of the dynamic microbiome evolution across thrips species

Insect Science, EarlyView.
Comprehensive survey of the microbiome in thrips. The dominant bacterial genera found in thrips include intracellular ones, such as Wolbachia and Spiroplasma, and extracellular ones, including Serratia, Pantoea, and Acinetobacter. We isolated and sequenced high‐quality genomes of two dominant symbionts, Pantoea dispersa and Serratia marcescens.

Measuring Industry Relatedness and Corporate Coherence [PDF]

Since the seminal work of Teece et al. (1994) firm diversification has been found to be a non-random process. The hidden deterministic nature of the diversification patterns is usually detected comparing expected (under a null hypothesys) and actual ...

When monophyly is not enough: Exclusivity as the key to defining a phylogenetic species concept [PDF]

, 2009
A natural starting place for developing a phylogenetic species concept is to examine monophyletic groups of organisms. Proponents of "the" Phylogenetic Species Concept fall into one of two camps.
