Global diversity of mayflies (Ephemeroptera, Insecta) in freshwater

  title={Global diversity of mayflies (Ephemeroptera, Insecta) in freshwater},
  author={Helen M Barber-James and Jean‐Luc Gattolliat and Michel Sartori and Michael D. Hubbard},
The extant global Ephemeroptera fauna is represented by over 3,000 described species in 42 families and more than 400 genera. The highest generic diversity occurs in the Neotropics, with a correspondingly high species diversity, while the Palaearctic has the lowest generic diversity, but a high species diversity. Such distribution patterns may relate to how long evolutionary processes have been carrying on in isolation in a bioregion. Over an extended period, there may be extinction of species… 
The family Baetidae (Insecta: Ephemeroptera): synthesis and future challenges
The systematics of the Baetidae has been the subject of much attention during the last three decades, with descriptions of new species and genera as well as several generic revisions, so an opportune time to evaluate the pertinence of these works.
New data on the distribution and ecology of the mayfly larvae (Insecta: Ephemeroptera) of Serbia (central part of the Balkan Peninsula)
The largest number of mayfly species was recorded within the Ju?na and Zapadna Morava river basins, while the lowest taxa richness was observed within the Sava basin.
PB Orden Ephemeroptera (Insecta) en Panamá: Listado de especies, distribución de géneros y comparación con la riqueza taxonómica regional
In Panama we have 33 species of mayflies reported to date, 11 of these species have Panamanian type localities. The main collections of this group occurred between 1970 and 1980, driven mainly by
Discovery of an alien species of mayfly in South America (Ephemeroptera)
The identity of the species, its distribution, along with its previous absence in regularly sampled sites, is a clear sign that the specimens of C. smaeleni found in Espírito Santo are introduced, well established, and that the colonization took place very recently.
Direct analysis of vicariance in Neotropical mayflies (Ephemeroptera).
The aim is to reconstruct area history in the Neotropics using the rationale of Barrier biogeography (Hovenkamp protocol), and presents eleven mayfly phylogenies, representing groups that evolved independently at least from the Jurassic.
Croatian mayflies (Insecta, Ephemeroptera): species diversity and distribution patterns
Based on the mayfly assemblage, sampling sites were first structured by ecoregion and then by habitat type, and in comparison with the surrounding countries, the Croatian mayfly fauna is the most similar to the Hungarian and Bosnian fauna.
Molecular phylogeny and timing of diversification in Alpine Rhithrogena (Ephemeroptera: Heptageniidae)
The authors' species-level analyses of five gene regions provide clearer definitions of species groups within European Rhithrogena, and a constant speciation rate over time suggests that the paleoclimatic fluctuations did not significantly influence the tempo of diversification of Alpine species.
Diversity of Lower Insects (Arthropoda: Hexapoda) in Colombia: I. Entognatha to Polyneoptera
Examination of insect diversity in Colombia in terms of number of families, genera and species, in light of the most recent systematic data on the orders treated, introduces the problem of evaluating species richness of insects in Colombia from historical and taxonomic-methodological perspectives.
From molecular hypotheses to valid species: description of three endemic species of Baetis (Ephemeroptera: Baetidae) from the Canary Islands
Detailed morphological analysis of specimens from Tenerife, Gran Canaria, La Palma, and La Gomera confirms the validity of the four species based on small but consistent differences in some characters and describes three new species described herein at the larval stage.


Trans-oceanic and endemic origins of the small minnow mayflies (Ephemeroptera, Baetidae) of Madagascar
It is concluded that the Malagasy mayfly fauna should be considered in a biogeographical context that extends beyond Madagascar itself, encompassing trans-oceanic dispersal within multiple lineages.
Toward a Phylogenetic Classification of the Ephemeroptera (Insecta): a Commentary on Systematics
Phylogenetic systematics is shown to have predictive and heuristic value for interpreting comparative biology, inferring adaptive evolution and biogeography, and also to have an important function in paleontological and ecological analyses.
Trends in Research in Ephemeroptera and Plecoptera
Since the most recent comprehensive review of the biology of Australian Ephemeroptera by Peters and Campbell in 1991, knowledge has been rapidly increasing and there have been additional useful biogeographical studies on previously little known taxa such as Ephemerellina.
Biogeography and Evolution of Ephemeroptera
The Hennig-Brundin concern for phyletics in biogeog­ raphy is basic to this review, but it is unconvincing for application to the classification· system.

The Panamerican Ephemeroptera fauna is evaluated with respect to the interchange of generic lineages and species between the Americas, and comparisons are drawn with classical studies of the American
Conserving Madagascar's Freshwater Biodiversity
In the face of ongoing environmental threats, links among microendemism, forest stream specialization, and basal phylogenetic position highlight the importance and vulnerability of these species and provide a powerful incentive for immediate conservation action.

The case of Plecoptera suggests that potamal invertebrates suffered as severe losses as did fish, suggesting that rhithral biodiversity is thought to be much more endangered by human impact than is presently recognized.
New data about the mayflies ( Ephemeroptera ) from Borneo
More than 40 mayfly genera have been collected in a lowland Dipterocarpaceae forest in East Kalimantan (Borneo, Indonesia) and this incredible mayfly diversity is among the highest ever reported so far for an area of less than 10x10 km.
The Principles Applied in Determining the Hierarchic Level of the Higher Categories of Ephemeroptera
THE ORDER Ephemeroptera (mayflies) is small enough (about 2,000 extant species and 170 genera described) to be readily comprehensible to a single worker. Since 1950, I have been engaged with several
Higher classification of the burrowing mayflies (Ephemeroptera: Scapphodonta)
A revised cladogram of the monophyletic groups of genera constituting the tusked burrowing mayflies (infraorder Scapphodonta) is presented, based in part on new analyses of relationships that have
