Osteological, Biological, and Genetic Consequences of Colonization of Fresh Waters by Marine Cottoid Fishes (Cottidae)

Integrative Zoology, EarlyView.
Lacustrine forms of Triglopsis from North American and European lakes are at different stages of evolution, making them a suitable model for testing hypotheses about evolutionary patterns and rates. An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus Triglopsis was carried out.

Parasites at the Summit: Unexpected Geographic Distribution of the Blood Parasite Lineage Found in the Endangered Giant Lizard of Tenerife

Integrative Zoology, EarlyView.
We combined microscopic screening and molecular phylogenetic analyses to characterize blood parasites infecting Gallotia intermedia from the coastal cliffs of Montaña de Guaza and to place these infections in a broader biogeographic context. We detected apicomplexan parasites of the genus Karyolysus infecting 53.6% of G.

Some Tuco‐Tucos Hide More Than Others: An Integrative Approach Reveals Cryptic Diversity in Ctenomys (Rodentia: Ctenomyidae) From Central Argentina

Integrative Zoology, EarlyView.
Here, we adopt an integrative framework (molecular phylogenetics and geometric morphometrics) to reassess patterns of diversity and differentiation across this region. We analyzed cytochrome b sequences and quantified cranial shape variation. Our analyses indicate the presence of three species groups (mendocinus, talarum, and tucumanus) and two ...

Ground‐penetrating radar amplitudes to roots: A numerical modelling framework for mapping coarse root system architecture

Methods in Ecology and Evolution, EarlyView.
Abstract Observations of three‐dimensional (3D) coarse root system architecture remain limited because most measurement approaches require excavation. Here, we combined dense single‐ and multi‐channel 500 MHz ground‐penetrating radar (GPR) surveys with a flow‐guided connectivity framework to non‐destructively characterise the coarse root architecture ...

Genotyping Contemporary Captive and Historical Wild Western Lowland Gorillas Indicates Captive Breeding Is Maintaining Genetic Diversity in a Critically Endangered Primate

Animal Conservation, EarlyView.
Captive populations of threatened species risk losing genetic diversity over time. We evaluated the genetic status of contemporary captive western lowland gorillas (Gorilla gorilla gorilla) at Howletts and Port Lympne and compared this with specimens from a historical wild population.
