Evolution of Generalists by Phenotypic Plasticity

iScience, 2020
Summary: Adapting organisms face a tension between specializing their phenotypes for certain ecological tasks and developing generalist strategies that permit persistence in multiple environmental conditions.

Opposing effects of plant traits on diversification

iScience, 2023
Summary: Species diversity can vary dramatically across lineages due to differences in speciation and extinction rates. Here, we explore the effects of several plant traits on diversification, finding that most traits have opposing effects on ...

A de novo evolved gene in the house mouse regulates female pregnancy cycles

eLife, 2019
The de novo emergence of new genes has been well documented through genomic analyses. However, a functional analysis, especially of very young protein-coding genes, is still largely lacking.

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

Mitochondrial 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 ...

Biology and Evolutionary Games [PDF]

, 2016
This chapter surveys some evolutionary games used in biological sciences. These include the Hawk-Dove game, the Prisoner’s Dilemma, Rock–Paper–Scissors, the war of attrition, the Habitat Selection game, predatorprey games, and signalling games.

Transcriptional effects of a positive feedback circuit in Drosophila melanogaster

BMC Genomics, 2017
Background Synthetic systems that use positive feedback have been developed to control human disease vectors and crop pests. The tTAV system, which has been deployed in several insect species, relies on a positive feedback circuit that can be inhibited ...

Differential fates of Kazald gene quartet: Ancestral roles in skeletogenesis and regeneration to putative innovations in fish and birds

iScience
Summary: Gene orthology inference across species is crucial to identify gains and losses of functions. The discovery in axolotl (Ambystoma mexicanum) of a regeneration-associated gene identified as either Kazald1 or Kazald2 led us to investigate its ...

Oncogenic stress alters predator-prey interactions between a globally invasive and a native planaria species

iScience
Summary: Oncogenic pressures, factors that increase tumor risk, are intensifying with human-driven environmental change, yet their ecological effects remain mainly unquantified.

Phase Angle as an Early Functional Biomarker of Cancer‐Related Fatigue in Pediatric Oncology: A Prospective Longitudinal Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric cancer remains a leading cause of morbidity and mortality worldwide, particularly in low‐and middle‐income countries. Cancer treatment may impair nutritional status, alter body composition, and exacerbate cancer‐related fatigue (CRF).
