Diversity of sunflower rust pathogen biotypes in the regions of the Russian Federation

Аграрная наука Евро-Северо-Востока, 2023
The spread and development of sunflower rust in the regions of the Russian Federation is due to the emergence of new biotypes of the pathogen, which have overcome the resistance of cultivated varieties and hybrids. The aim of the research was to identify

A view from above: Unmanned aerial vehicles ( UAV s) provide a new tool for assessing liana infestation in tropical forest canopies

Journal of Applied Ecology, 2019
1. Tropical forests store and sequester large quantities of carbon, mitigating climate change. Lianas (woody vines) are important tropical forest components, most conspicuous in the canopy. Lianas reduce forest carbon uptake and their recent increase may,

Biogeographical patterns of endolithic infestation in an invasive and an indigenous intertidal marine ecosystem engineer [PDF]

, 2019
By altering the phenotypic properties of their hosts, endolithic parasites can modulate the engineering processes of marine ecosystem engineers. Here, we assessed the biogeographical patterns of species assemblages, prevalence and impact of endolithic ...

Parasite spread at the domestic animal - wildlife interface: anthropogenic habitat use, phylogeny and body mass drive risk of cat and dog flea (Ctenocephalides spp.) infestation in wild mammals

Parasites & Vectors, 2018
Spillover of parasites at the domestic animal - wildlife interface is a pervasive threat to animal health. Cat and dog fleas (Ctenocephalides felis and C. canis) are among the world’s most invasive and economically important ectoparasites.

Meteorological variables and mosquito monitoring are good predictors for infestation trends of Aedes aegypti, the vector of dengue, chikungunya and Zika

Parasites & Vectors, 2017
BackgroundAedes aegypti is an important vector for arboviroses and widely distributed throughout the world. Climatic factors can influence vector population dynamics and, consequently, disease transmission.
