Transcriptomic analyses of the termite, Cryptotermes secundus, reveal a gene network underlying a long lifespan and high fecundity

Communications Biology, 2021
Lin et al. use transcriptomics in the social termite, Cryptotermes secundus, to investigate potential pathways underlying the long lifespan and high fecundity of insect queens.

Robotics as a Comparative Method in Ecology and Evolutionary Biology

Integrative And Comparative Biology, 2022
AbstractComparative biologists have typically used one or more of the following methods to assist in evaluating the proposed functional and performance significance of individual traits: comparative phylogenetic analysis, direct interspecific comparison among species, genetic modification, experimental alteration of morphology (for example by ...

Growth factor gene IGF1 is associated with bill size in the black-bellied seedcracker Pyrenestes ostrinus

Nature Communications, 2018
Pyrenestes finches have a bill size polymorphism thought to be maintained by disruptive selection. Here, the authors identify a single candidate region, including insulin-like growth factor 1, differentiating small and large bill size morphs and a wider ...

Urbanization and a green corridor do not impact genetic divergence in common milkweed (Asclepias syriaca L.)

Scientific Reports, 2023
Urbanization is altering landscapes globally at an unprecedented rate. While ecological differences between urban and rural environments often promote phenotypic divergence among populations, it is unclear to what degree these trait differences arise ...

Chance promoter activities illuminate the origins of eukaryotic intergenic transcriptions

Nature Communications, 2023
It is debated whether the pervasive intergenic transcription from eukaryotic genomes has functional significance. Here, Xu et al. find that only 1–5% of yeast intergenic transcription is unattributable to chance promoter activity or neighboring gene ...

The diversity of eco-evolutionary dynamics: comparing the feedbacks between ecology and evolution across scales [PDF]

, 2019
1.Evidence of reciprocal influences between ecological and evolutionary processes (eco‐evolutionary dynamics) is accumulating at different levels of biological organisation, ranging from populations to communities and even ecosystems.

No evidence for differential sociosexual behavior and space use in the color morphs of the European common wall lizard (Podarcis muralis) [PDF]

, 2022
Explaining the evolutionary origin and maintenance of color polymorphisms is a major challenge in evolutionary biology. Such polymorphisms are commonly thought to reflect the existence of alternative behavioral or life-history strategies under negative ...

An integrative genomic and phenomic analysis to investigate the nature of plant species in Escallonia (Escalloniaceae)

Scientific Reports, 2021
What we mean by species and whether they have any biological reality has been debated since the early days of evolutionary biology. Some biologists even suggest that plant species are created by taxonomists as a subjective, artificial division of nature.

Coevolutionary transitions from antagonism to mutualism explained by the Co-Opted Antagonist Hypothesis

Nature Communications, 2021
While there is strong evidence that many mutualisms evolved from antagonism, how or why remains unclear. A study combining theory and a data-based model sheds light on how mutualisms evolve without extremely tight host fidelity and how ecological context

Estimating pollination success with novel artificial flowers: Effects of nectar concentration

Journal of Pollination Ecology, 2012
We developed novel artificial flowers that dispense and receive powdered food dyes as pollen analogues while their nectar is replenished by capillary action.
