Phylogeny‐based generic delimitations of the diverse leafhopper tribe Gyponini, including the establishment of a new tribe of Iassinae (Hemiptera: Cicadellidae)

open access: yesSystematic Entomology, Volume 51, Issue 3, July‐September 2026.
Phylogenetic relationships among 97.6% of Gyponini genera and 97.4% of subgenera were inferred using morphological and multilocus molecular data. Analyses support the monophyly of Gyponini, transfer Hoplojassini to Hylicinae and establish Chilenanini trib. nov. within Iassinae.

Placental insufficiency markers to assess the risk of non‐chromosomal genetic conditions in early‐onset fetal growth restriction

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 4, Page 492-499, April 2026.
ABSTRACT Objectives To assess the value of placental insufficiency markers for estimating the risk of genetic anomalies in fetuses with isolated early‐onset fetal growth restriction (FGR), defined as an estimated fetal weight ≤ 3rd percentile diagnosed ≤ 28 + 6 weeks' gestation.

Ultrasound features in early pregnancy for predicting abnormal karyotype in first‐trimester miscarriage

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 3, Page 376-384, March 2026.
ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital ...

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and

Pixelated pathologies: Camera trapping as a tool for monitoring wildlife health

open access: yesJournal of Applied Ecology, Volume 62, Issue 11, Page 2894-2913, November 2025.
Given the increasing emergence of diseases, some with conservation and public health implications, improving and expanding wildlife health surveillance strategies is imperative. Camera trapping is particularly relevant for detecting new outbreaks, monitoring high‐risk zones and evaluating risk mitigation measures. Abstract Camera trapping has become an

Diversidade genética com base em características morfológicas e de marcadores moleculares (RAPD) em passifloras silvestres ornamentais

open access: yesOrnamental Horticulture, 2007
Objetivando conhecer a diversidade genética para auxiliar na seleção de genitores para obtenção de híbridos ornamentais interespecíficos, procedeu-se à caracterização morfológica e ao uso de marcadores moleculares para o estudo de diversidade genética ...
