Spatial distribution and seasonal changes of mayflies (Insecta, Ephemeroptera) in a Western Balkan peat bog

open access: yesZooKeys, 2016
Peat bogs are unique wetland ecosystems of high conservation value all over the world, yet data on the macroinvertebrates (including mayfly assemblages) in these habitats are still scarce.

Taxonomy, Distribution and Life Cycle of the Maghrebian Endemic Rhithrogena sartorii (Ephemeroptera: Heptageniidae) in Algeria

open access: yesDiversity, 2021
Despite being recorded in Algeria since the nineteenth century, the genus Rhithrogena has never been the object of a taxonomical study and no identified species is known from this country.

Evidence for adaptive explanations of semelparity in animals

open access: yesBiological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Analysis and Classification of Partial Shading Conditions in Photovoltaic Arrays

open access: yesEnergy Science &Engineering, EarlyView.
This study presents new mathematical models for describing P–V curve extrema under different shading scenarios and applies machine learning classifiers that use features derived from P–V characteristics for accurate fault identification. ABSTRACT With the escalating global transition toward renewable energy, ensuring the operational stability and ...

Ecological scale mediates nonlinear relationships of animal nutrient excretion with dissolved organic matter

open access: yesJournal of Animal Ecology, EarlyView.
We show that nutrient excretion by vertebrates and invertebrates varies nonlinearly with dissolved organic matter concentration and composition and by taxonomic rank, with stronger patterns at the individual compared to the community level. Our findings highlight the importance of examining animal‐mediated nutrient cycling across taxa and ecological ...

The Good, the Bad, and the Lethal: Gene Expression and Metabolomics Reveal Physiological Mechanisms Underlying Chronic Thermal Effects in Mayfly Larvae (Neocloeon triangulifer)

open access: yesFrontiers in Ecology and Evolution, 2018
Temperature dictates the performance of aquatic ectotherms. However, the physiological and biochemical processes that drive thermally-mediated life history patterns (and limits) remain poorly understood because they are rarely studied simultaneously.

Observations on the Burrow Structures and Larval Behavior of Ephoron shigae (Takahashi, 1924) (Ephemeroptera: Polymitarcyidae) in River Sediments

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT The larvae of the mayfly Ephoron shigae (Takahashi, 1924) (Ephemeroptera: Polymitarcyidae) inhabit distinctive U‐shaped burrows in river and lake sediments, yet their ecology remains poorly documented. Using newly developed mechatronic technology, we obtained continuous observations that revealed new aspects of larval behavior.

Twenty-One Mayfly Gynandromorphic Cases from China

open access: yesDiversity
Gynandromorphism of mayfly has unique biological and scientific value. However, most cases of previous studies on this phenomenon were from Europe and America, with only two cases reported from China.

A new species of flat-headed mayfly Afronurus meenmutti (Ephemeroptera: Heptageniidae: Ecdyonurinae) from Kerala, India

open access: yesJournal of Threatened Taxa, 2021
A new species of mayfly (Heptageniidae: Ecdyonurinae) Afronurus meenmutti sp. nov. is described based on larvae and imagoes from the state of Kerala, southern India. The main characteristics that distinguish the new species from all other species are in
