The mitochondrial genome of Caenis sp. (Ephemeroptera: Caenidae) and the phylogeny of Ephemeroptera in Pterygota

open access: yesMitochondrial DNA. Part B. Resources, 2018
The phylogenetic relationship between Ephemeroptera (mayflies) and Odonata (dragonflies and damselflies) remains hotly debated in the insect evolution community. We sequenced the complete mitochondrial genome of Caenis sp.

Criação e Transporte de Ninfas de Ephemeroptera (Insecta) em Campo

open access: yesEntomoBrasilis, 2013
Muitas espécies de Ephemeroptera são conhecidas somente em um estágio, normalmente adulto ou ninfa. Nesse estudo é proposto uma metodologia para transporte e criação de ninfas em campo Rearing and Transport of Mayfly Nymphs in the Field Abstract ...

Formation of groupings of mayfly larvae (Ephemeroptera) in the area of small hydrological structures, in the streams of the Kamienica Nawojowska river basin (the Sądeckie Beskids, Poland)

open access: yesEkológia (Bratislava), 2016
Anthropogenic modification of abiotic factor in turn influencez biotic communities. The aim of this study was to characterise clusters of mayflies in selected streams of Kamienica Nawojowska river basin in conjunction with small, lateral hydrological ...

Thermal niche breadth shapes regional elevational range sizes of tropical‐like mountain stream insects: evidence for Janzen's tropical mountain passes hypothesis

open access: yesEcography, EarlyView.
The core of Janzen's tropical mountain passes hypothesis is that relatively stable annual temperature variation limits species' thermal tolerances breadth, which, in combination with steep elevational temperature gradients, constrains the elevational distributions of these species. In addition to thermal niche breadth, elevational ranges were shaped by

The first complete mitochondrial genome of Hexagenia rigida Mc Dunnough, 1924 (Ephemeroptera: Ephemeridae) and its phylogeny

open access: yesMitochondrial DNA. Part B. Resources, 2022
The phylogenetic relationship of Ephemeridae (Insect: Ephemeroptera) remains hotly debated using mitochondrial (mt) genomes. All previously reported mt genomes of Ephemeridae belong to the genus Ephemera.

A Macroinvertebrate‐Based Flow Index Elucidates Responses to Environmental Water in a Highly Regulated River

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Macroinvertebrate‐based flow indices have potential application to guiding environmental flow allocations and monitoring their effectiveness, but their sensitivity to such flows has seldom been tested. We examined the response of the Australian Macroinvertebrate Flow Index (AMFI), calculated from family‐level data, to three stages of ...

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Urban bats show dietary flexibility in aquatic arthropod consumption at urban and rural waterbodies

open access: yesWildlife Biology, EarlyView.
Urban waterbodies are critical for biodiversity and provide feeding grounds for insectivorous bats. Yet, how urbanisation affects bats' food choices at urban waterbodies and the role of emergent aquatic arthropods remain poorly understood. We compared the diet of three urban bat species – Vespadelus vulturnus, Chalinolobus gouldii,and Myotis macropus –

Diurnal variations in the diet of 0 to 3 years old Atlantic salmon Salmo salar L. under semiarctic summer conditions in the Alta River, Northern Norway

open access: yesFauna Norvegica, 1986
The stomach contents of 0 to 3 year old salmon were investigated throughout a single 20 hour period in each of July, August and September 1981. There was no marked diurnal variation in stomach content of fry, while that of parr indicated nocturnal ...

Fauna of Ephemeroptera in the running waters of west Serbia [PDF]

open access: yesArchives of Biological Sciences, 2002
During the period 1988 - 1996 the Ephemeroptera diversity in West Serbia was studied. These investigations included 124 springs, considerable number of spring regions, as well as rivers: the Sušica, Djetinja, Skrapež Pocibrava, Banja, Gradac, Jablanica ...
