TLDR
The phylogenetic relationships within the subfamily Alosinae are known only from the phylogenetic tree of the species of the genus "Alosina" as discussed by the authors, but little is known about the relationships among these species.Abstract:
(subfamily Alosinae) has received research atten-tion concerning its ecology and life-history (Bagliniere,2000 and references therein), as well as conservationissues due to recent declines in many of its species (Wald-man, 2003). Despite their importance, little is knownabout the phylogenetic relationships withinread more

Speciation in Freshwater Fishes
TL;DR: Major research directions in the years to come include understanding the transition from extrinsic environment-dependent to intrinsic reproductive isolation and its influences on species persistence and understanding the extrinsics and intrinsic constraints to speciation and how these relate to broad-scale diversification patterns through time.

Independent evolutionary origins of landlocked alewife populations and rapid parallel evolution of phenotypic traits.
TL;DR: A ‘phylogenetic raceme’ model of landlocked alewife divergence is supported, with anadromous populations forming an ancestral core from which landlocked populations independently diverged.

Molecular diversification of salamanders of the tropical American genus Bolitoglossa (Caudata : Plethodontidae) and its evolutionary and biogeographical implications
TL;DR: South America was invaded by members of one clade, Eladinea, which is infer to have dispersed to South America prior to closure of the Panamanian Portal, and the existence of large genetic diversity within morphologically homogeneous taxa is uncovered.

Human disturbance causes the formation of a hybrid swarm between two naturally sympatric fish species.

TL;DR: It is demonstrated that habitat alteration can lead to hybrid swarm formation between divergent species that naturally occur sympatrically, and provided empirical evidence that reinforcement does not always sustain reproductive isolation under such circumstances.

Taxonomy, biogeography and evolution of Euproctus (Amphibia: Salamandridae), with the resurrection of the genus Calotriton and the description of a new endemic species from the Iberian Peninsula
Salvador Carranza,Fèlix Amat +1 more
TL;DR: The polyphyly of Euproctus (s.l.) contradicts previous, well-accepted, biogeographical hypotheses and represents a clear case of convergence, involving several morphological traits and a unique reproductive behaviour that is advantageous in stream situations.
