The genetic architecture underlying the evolution of a rare piscivorous life history form in brown trout after secondary contact and strong introgression [PDF]

open access: yes, 2018
Identifying the genetic basis underlying phenotypic divergence and reproductive isolation is a longstanding problem in evolutionary biology. Genetic signals of adaptation and reproductive isolation are often confounded by a wide range of factors, such as

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

open access: yesThe Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

Contribution to the discussions on the origin of the cerrado biome: Brazilian savanna

open access: yesBrazilian Journal of Biology
Theories that attempt to explain the origin of the cerrado biome are mostly based on the isolated action of three major factors: climate, fire and soil. Another factor that has been mentioned is that of human interference.

A Gene Expression Screen Identifies \u3cem\u3eEARLI1\u3c/em\u3e as a Novel Vernalization-Responsive Gene in \u3cem\u3eArabidopsis Thaliana\u3c/em\u3e [PDF]

open access: yes, 2000
Vernalization promotes early flowering in late ecotypes of Arabidopsis thaliana. The mechanisms of vernalization are poorly understood. A subtractive hybridization approach was used to isolate vernalization-responsive genes from a late-flowering ecotype of

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

open access: yesBiological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.
