Effects of L‐Tyrosine Ingestion on Endurance Performance in Mentally Fatigued Cyclists

European Journal of Sport Science, Volume 26, Issue 4, April 2026.
ABSTRACT This study investigated whether L‐tyrosine supplementation enhances endurance performance in mentally fatigued cyclists. Twelve recreational cyclists completed two constant‐workload tests to exhaustion cycling tests under two experimental conditions at 80% of maximal endurance power output: L‐tyrosine ingestion (300 mg/kg) under mental fatigue

Incomplete lineage sorting and hybridization as sources of gene tree discordance among species of the Geminata clade of Solanum (Solanaceae)

TAXON, Volume 75, Issue 2, April 2026.
Abstract Discordance among gene trees, including discrepancies with the species tree, is increasingly reported in analyses of phylogenomic data. Such discordance can result from technical issues such as misalignment, paralogy, or model misfit, or from biological processes such as incomplete lineage sorting (ILS), hybridization with introgression, or ...

Nocturnal Lepidopterans as Essential Pollinators of Aspidosperma pyrifolium (Apocynaceae), a Keystone Tree in the Caatinga Dry Forest

Journal of Applied Entomology, Volume 150, Issue 3, Page 351-363, April 2026.
ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

When Numbers Mean Money: Pest Precision Sampling in High‐Density Mango Crops

Journal of Applied Entomology, Volume 150, Issue 3, Page 333-339, April 2026.
ABSTRACT The development of sampling plans is essential for assertive decision‐making in integrated pest management programs. The present study aimed to develop a plan for monitoring major mango pests in high‐density mango crops in Brazil. For this purpose, the influence of the position of the branch to be sampled in the canopy (internal and external ...
