Navigating the unfolding open data landscape in ecology and evolution [Nature Ecology & Evolution]

Keywords : ecology, evolution, research data

Open access to data is revolutionizing the sciences. To allow ecologists and evolutionary biologists to confidently find and use the existing data, we provide an overview of the landscape of online data infrastructures, and highlight the key points to consider when using open data. We introduce an online collaborative platform to keep a community-driven, updated list of the best sources that enable search for data in one interface. In doing so, our aim is to lower the barrier to accessing open data, and encourage its use by researchers hoping to increase the scope, reliability and value of their findings.

Gene duplicates resolving sexual conflict rapidly evolved essential gametogenesis functions [Nature Ecology & Evolution]

Keywords : evolution, genetics

Males and females have different fitness optima but share the vast majority of their genomes, causing an inherent genetic conflict between the two sexes that must be resolved to achieve maximal population fitness. We show that two tandem duplicate genes found specifically in Drosophila melanogaster are sexually antagonistic, but rapidly evolved sex-specific functions and expression patterns that mitigate their antagonistic effects.(...)

A physiological perspective on fisheries-induced evolution [Evolutionary Applications]

Keywords : anthropogenic change, ecophysiology, fishing, harvest-induced selection, metabolic rate

There is increasing evidence that intense fishing pressure is not only depleting fish stocks but also causing evolutionary changes to fish populations. In particular, body size and fecundity in wild fish populations may be altered in response to the high and often size-selective mortality exerted by fisheries. While these effects can have serious consequences for the viability of fish populations, there are also a range of traits not directly related to body size which could also affect susceptibility to capture by fishing gears—and therefore fisheries-induced evolution (FIE)—but which have to date been ignored.(...)

Drosophila melanogaster establishes a species-specific mutualistic interaction with stable gut-colonizing bacteria [BioRxiv]

Animals live together with diverse bacteria that can impact their biology. In Drosophila melanogaster, gut-associated bacterial communities are relatively simple in composition but also have a strong impact on host development and physiology. However, it is still unknown if bacteria can proliferate and stably associate with the gut of D. melanogaster. In fact, it is generally assumed that bacteria are transient and their constant ingestion with food is required to maintain their presence in the gut. Here, we identify bacterial species from wild-caught D. melanogaster that stably associate with the host independently of continuous inoculation. Moreover, we show that specific Acetobacter wild isolates can proliferate in the gut.(...)

Grass diversification in Madagascar: In situ radiation of two large C3 shade clades and support for a Miocene to Pliocene origin of C4 grassy biomes [Journal of Biogeography]

Jean Hackel, Guillaume Besnard

Grasses (Poaceae) are found in all major habitats of Madagascar and have a particular importance in C4 grasslands, whose origins are controversial. We aimed to estimate the number, age and origins of endemic grass lineages in the Madagascar region, and to compare the diversification of C3 and C4 taxa.
