Same data, different analysts: variation in effect sizes due to analytical decisions in ecology and evolutionary biology. [PDF]

open access: yesBMC Biol
Although variation in effect sizes and predicted values among studies of similar phenomena is inevitable, such variation far exceeds what might be produced by sampling error alone. One possible explanation for variation among results is differences among

Zebras of all stripes repel biting flies at close range

open access: yesScientific Reports, 2022
The best-supported hypothesis for why zebras have stripes is that stripes repel biting flies. While this effect is well-established, the mechanism behind it remains elusive.

Complete mitochondrial genomes provide current refined phylogenomic hypotheses for relationships among ten Hirundo species

open access: yesMitochondrial DNA. Part B. Resources, 2020
Hirundo is the most species-rich genus of the passerine swallow family (Hirundinidae) and has a cosmopolitan distribution. Here we report the complete, annotated mitochondrial genomes for 25 individuals from 10 of the 14 extant Hirundo species; these ...

Cartilage diversification and modularity drove the evolution of the ancestral vertebrate head skeleton

open access: yesEvoDevo, 2023
The vertebrate head skeleton has evolved a myriad of forms since their divergence from invertebrate chordates. The connection between novel gene expression and cell types is therefore of importance in this process.

Comparative analysis of morabine grasshopper genomes reveals highly abundant transposable elements and rapidly proliferating satellite DNA repeats

open access: yesBMC Biology, 2020
Background Repetitive DNA sequences, including transposable elements (TEs) and tandemly repeated satellite DNA (satDNAs), collectively called the “repeatome”, are found in high proportion in organisms across the Tree of Life.

The use of telomere length in ecology and evolutionary biology [PDF]

open access: yesHeredity, 2010
The measurement of telomere length (TL) is a genetic tool that is beginning to be employed widely in ecological and evolutionary studies as marker of age and fitness. The adoption of this approach has been accelerated by the development of telomere quantitative PCR, which enables the screening of large numbers of samples with little effort.

The microbiome extends host evolutionary potential

open access: yesNature Communications, 2021
The microbiome is becoming recognized as a key determinant of host phenotype. Here, Henry et al. present a framework for building our understanding of how the microbiome also influences host evolution, review empirical examples and research approaches ...

Is bigger better? The relationship between size and reproduction in female Asian elephants [PDF]

open access: yes, 2022
The limited availability of resources is predicted to impose trade-offs between growth, reproduction and self-maintenance in animals. However, although some studies have shown that early reproduction suppresses growth, reproduction positively ...

The Collection of Zoosporic Eufungi at the University of Michigan (CZEUM): introducing a new repository of barcoded Chytridiomyceta and Blastocladiomycota cultures

open access: yesIMA Fungus, 2020
We formed the Collection of Zoosporic Eufungi at the University of Michigan (CZEUM) in 2018 as a cryopreserved fungal collection consolidating the University of Maine Culture Collection (UMCC, or JEL), the University of Alabama Chytrid Culture Collection
