Potential vectors of Leishmaniases in the Environmental Protection Area and Tinguá Federal Biological Reserve, Municipality of Nova Iguaçu, Rio de Janeiro, Brazil

open access: yesMedical and Veterinary Entomology, EarlyView.
This study was to describe the composition of sand fly fauna, detect potential vectors of Leishmania spp. in the Tinguá district, an ATL endemic, Rio de Janeiro, Brazil. Seven species of vectorial importance in the epidemiological cycle of leishmaniasis was observed: Nyssomyia intermedia, Migonemyia migonei, Pintomyia fischeri, Psychodopygus hirsutus ...

Biogeography and host associations of Russula subsection Xerampelinae based on large‐scale analysis of UNITE sequence data

open access: yesNew Phytologist, EarlyView.
Summary Estimating fungal geographic ranges and niche potential is limited by the ephemeral nature of fruiting bodies. While environmental DNA offers broader insights, species‐level identification remains difficult due to uncertain sequence clustering thresholds, low interspecific variation in barcoding regions, and limited taxonomic resolution.

A Repertoire of Major Genes From Crop Wild Relatives for Breeding Disease‐Resistant Wheat, Rice, Maize, Soybean and Cotton Crops

open access: yesPlant Breeding, EarlyView.
ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

A new genus for the Neotropical species of Aesalus Fabricius, with descriptions of eight new species (Coleoptera: Lucanidae: Aesalinae) [PDF]

open access: yes, 2013
The Neotropical members of the genus Aesalus Fabricius (Coleoptera: Lucanidae: Aesalinae) are transferred to a new genus, Trogellus, due to their morphological dissimilarity and molecular divergence from the Old World species of Aesalus, and the new ...

Allium genetic resources with particular reference to onion [PDF]

open access: yes, 2008
As in many other crop species, also in Allium crops genetic erosion is taking place. In this mini review the current global state of the art is presented on Allium ex situ genetic resources and more in particular on onion genetic resources.

Satellite DNA in Paphiopedilum subgenus Parvisepalum as revealed by high-throughput sequencing and fluorescent in situ hybridization

open access: yesBMC Genomics, 2018
Background Satellite DNA is a rapidly diverging, largely repetitive DNA component of many eukaryotic genomes. Here we analyse the evolutionary dynamics of a satellite DNA repeat in the genomes of a group of Asian subtropical lady slipper orchids ...

Starving for oxygen: the effect of hypoxia on seed germination and secondary dormancy induction in Mediterranean temporary ponds plant species

open access: yesPlant Biology, EarlyView.
This study examined the germination adaptations to hypoxia of species along a plant zonation in Mediterranean temporary ponds, highlighting the key traits that support their survival and regeneration. Abstract Mediterranean temporary ponds (MTPs) are dynamic habitats where low levels of dissolved oxygen can significantly impact plant life.

Molecular Phylogeny, Species Delimitation, and Biogeography of the Varunid Crab Genus Metaplax (Crustacea, Varunidae)

open access: yesZoologica Scripta, EarlyView.
ABSTRACT The Indo‐West Pacific genus Metaplax comprises 11 recognised species inhabiting intertidal mudflats, some adjacent to mangroves. To resolve long‐standing uncertainties, we analysed mitochondrial (COI, 16S) and nuclear (28S) markers. Phylogenetic analyses recovered Metaplax as monophyletic and resolved four well‐supported clades—the M ...
