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.

Mayfly emergence production and body length response to hydrology in a tropical lowland stream [PDF]

open access: yesPeerJ, 2020
Background Hydrological impacts on aquatic biota have been assessed in numerous empirical studies. Aquatic insects are severely affected by population declines and consequent diversity loss.

Mayfly and Habitat condition data [PDF]

open access: yes, 2020
Mayfly community data collected in the Luvuvhu catchment, RSA. Data was collected at 23 sites for 12 months. At each sites, one biotope 'stones-in-current' was sampled with six samples collected from six different stones.

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 ...

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.

Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

open access: yesOikos, EarlyView.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...
