Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

open access: yesAdvanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

Speciation, Phenotypic Variation and Plasticity: What Can Endocrine Disruptors Tell Us?

open access: yesInternational Journal of Endocrinology, 2013
Phenotype variability, phenotypic plasticity, and the inheritance of phenotypic traits constitute the fundamental ground of processes such as individuation, individual and species adaptation and ultimately speciation. Even though traditional evolutionary

Genomics of Rapid Incipient Speciation in Sympatric Threespine Stickleback. [PDF]

open access: yesPLoS Genetics, 2016
Ecological speciation is the process by which reproductively isolated populations emerge as a consequence of divergent natural or ecologically-mediated sexual selection.

How chromosomal rearrangements shape adaptation and speciation: Case studies in Drosophila pseudoobscura and its sibling species Drosophila persimilis

open access: yesMolecular Ecology, 2018
The gene arrangements of Drosophila have played a prominent role in the history of evolutionary biology from the original quantification of genetic diversity to current studies of the mechanisms for the origin and establishment of new inversion mutations

The Trichinella Super‐Pangenome Reveals the Evolution of Encapsulation and Predicted Host–Parasite Protein Interactions

open access: yesAdvanced Science, EarlyView.
ABSTRACT The muscle capsule of Trichinella is a critical structure that impedes immune attacks and drug penetration, yet the molecular mechanisms underlying its formation remain poorly understood. Using a high‐quality super‐pangenome comprising 12 Trichinella species, we compared extensive genomic variations between encapsulating and non‐encapsulating ...

Divergent Roles of mGlu2 and mGlu3 Receptors in Amyloid‐β Production and Cognitive Dysfunctions in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
This study explores the opposing effects of the mGluR2 and mGluR3 receptors on amyloid precursor protein processing. mGluR2 promotes amyloidogenic cleavage, while mGluR3 favors non‐amyloidogenic pathways. Using a brain‐penetrant nanobody as a mGluR2 positive allosteric modulator, the study uncovers how its chronic activation aggravates amyloid‐β burden

Aridification and major geotectonic landscape change shaped an extraordinary species radiation across a world’s extreme elevational gradient

open access: yesCommunications Biology
Understanding the profound influence of climatic and tectonic histories on adaptation and speciation is a crucial focus in biology research. While voyages like Humboldt’s expedition shaped our understanding of adaptation, the origin of current ...

Difference in calcium speciation in leaves of golden Camellia species from calcareous soil and acidic soil habitats

open access: yesGuangxi Zhiwu, 2023
In order to study the calcium speciation characteristics in leaves of golden Camellia species under different habitats, 10 species of golden Camellia from calcareous soil habitats and four species from acidic soil habitats were used as the research ...

Ecosystem size predicts eco-morphological variability in a postglacial diversification [PDF]

open access: yes, 2017
Identifying the processes by which new phenotypes and species emerge has been a long-standing effort in evolutionary biology. Young adaptive radiations provide a model to study patterns of morphological and ecological diversification in environmental ...

A Catalytic Osmium Redox Couple Collapses Cancer Redox Balance

open access: yesAdvanced Science, EarlyView.
A stable Os(III)/Os(IV) redox couple is developed to disrupt the tumor cell redox balance by concurrently catalyzing ROS generation and GSH depletion. Osmium‐treated cells exhibit multiple cell death pathways, including apoptosis, ferroptosis, and immunogenic cell death.
