Sequence Capture Versus Restriction Site Associated DNA Sequencing for Phylogeography [PDF]
Genomic datasets generated with massively parallel sequencing methods have the potential to propel systematics in new and exciting directions, but selecting appropriate markers and methods is not straightforward. We applied two approaches with particular promise for systematics, restriction site associated DNA sequencing (RAD-Seq) and sequence capture (

We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...

Characterization of the Cubamyces Menziesii Terpenome
The genome of Cubamyces menziesii reveals 18 putative sesquiterpene cyclase genes. These genes are cloned and expressed in Escherichia coli, yielding 10 active enzymes. Using farnesyl diphosphate as substrate, the enzymes are analyzed, and the products characterized after bioconversion, uncovering diverse sesquiterpene structures. This study highlights

Review of the Neotropical Charipinae (Hymenoptera, Cynipoidea, Figitidae)
A review of the Neotropical Charipinae is given, with 35 species from four genera: Alloxysta, Apocharips, Dilyta and Phaenoglyphis. One new species, Alloxysta centroamericana Ferrer-Suay & Pujade-Villar sp. nov.

The scaling of seed‐dispersal specialization in interaction networks across levels of organization
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

ABSTRACT This study evaluates land use and land cover (LULC) changes and their impacts on the fish community of a neotropical stream in the Sorocaba River basin, Brazil, from 2006 to 2023. The watershed experienced landscape changes over time, categorized into four periods: rural interventions, urban interventions, restorative interventions, and post ...

Land Use Effects on Organic Carbon in Andean Volcanic Ash Soils
ABSTRACT Background Both organic carbon (OC) stocks and labile OC (LOC) fractions are important indicators of soil health and are sensitive to land use change. Aims To study the effects of land use change on these indicators in montane volcanic ash soils, a soil transect was surveyed in northern Ecuador. Methods Samples were collected from 0–30, 30–60,
