1.- Heptageniidae, Ephemerellidae, Leptophlebiidae & Palingeniidae
PRIVATE UBRARV OF WILLIAM L. PETERS Revue suisse Zool. I Tome 99 Fasc. 4 p. 835-858 I Geneve, decembre 1992 Mayflies from Israel (lnsecta; Ephemeroptera) 1.- Heptageniidae, Ephemerellidae, Leptophlebiidae & Palingeniidae * by Michel SARTORI 1 With 45 figures ABSTRACT This paper is the first part of a work dealing with the mayfly fauna of Israel. Eleven species are reported here. The most diversified family is the Heptageniidae with six species belonging to six different genera: Rhithrogena znojkoi (Tshemova), Epeorus zaitzevi Tshemova, Ecdyonurus asiaeminoris Demoulin, Electrogena galileae (Demoulin) (comb. nov.), Afronurus kugleri Demoulin and Heptagenia samochai (Demoulin) (comb. nov.). E. zaitzevi is new for the fauna of Israel. The male of H. samochai is described for the first time and the synonymy with H. lutea Kluge (syn. nov.) is proposed. Eggs of the six species are described and illustrated. Keys are provided for nymphs and adults. Ephemerellidae are represented by a single species, Ephemerella mesoleuca (Brauer). Leptophlebiid species are: Paraleptophlebia submarginata (Stephens), Choroterpes (Ch.) picteti Eaton and Choroterpes (Euthraulus) ortali nov. sp. described at all stages. New features to distinguish the nymphs of the Mediterranean Euthraulus species are provided. One species of Palingeniidae has been found in the collections of Bet Gordon Museum in Deganya: Palingenia orientalis Chopra. The female of this species is described for the first time. P. orientalis disappeared from the investigated area in the early fifties. Some geographical data are given on the distribution of the species inside and outside the investigated area, as well as some ecological observations. For instance, underwater emergence is reported for the first time in the genus Afronurus. -

CHAPTER 4: EPHEMEROPTERA (Mayflies)
Guide to Aquatic Invertebrate Families of Mongolia | 2009 CHAPTER 4 EPHEMEROPTERA (Mayflies) EPHEMEROPTERA Draft June 17, 2009 Chapter 4 | EPHEMEROPTERA 45 Guide to Aquatic Invertebrate Families of Mongolia | 2009 ORDER EPHEMEROPTERA Mayflies 4 Mayfly larvae are found in a variety of locations including lakes, wetlands, streams, and rivers, but they are most common and diverse in lotic habitats. They are common and abundant in stream riffles and pools, at lake margins and in some cases lake bottoms. All mayfly larvae are aquatic with terrestrial adults. In most mayfly species the adult only lives for 1-2 days. Consequently, the majority of a mayfly’s life is spent in the water as a larva. The adult lifespan is so short there is no need for the insect to feed and therefore the adult does not possess functional mouthparts. Mayflies are often an indicator of good water quality because most mayflies are relatively intolerant of pollution. Mayflies are also an important food source for fish. Ephemeroptera Morphology Most mayflies have three caudal filaments (tails) (Figure 4.1) although in some taxa the terminal filament (middle tail) is greatly reduced and there appear to be only two caudal filaments (only one genus actually lacks the terminal filament). Mayflies have gills on the dorsal surface of the abdomen (Figure 4.1), but the number and shape of these gills vary widely between taxa. All mayflies possess only one tarsal claw at the end of each leg (Figure 4.1). Characters such as gill shape, gill position, and tarsal claw shape are used to separate different mayfly families. -

A Synopsis of the Pre-Human Avifauna of the Mascarene Islands
– 195 – Paleornithological Research 2013 Proceed. 8th Inter nat. Meeting Society of Avian Paleontology and Evolution Ursula B. Göhlich & Andreas Kroh (Eds) A synopsis of the pre-human avifauna of the Mascarene Islands JULIAN P. HUME Bird Group, Department of Life Sciences, The Natural History Museum, Tring, UK Abstract — The isolated Mascarene Islands of Mauritius, Réunion and Rodrigues are situated in the south- western Indian Ocean. All are volcanic in origin and have never been connected to each other or any other land mass. Despite their comparatively close proximity to each other, each island differs topographically and the islands have generally distinct avifaunas. The Mascarenes remained pristine until recently, resulting in some documentation of their ecology being made before they rapidly suffered severe degradation by humans. The first major fossil discoveries were made in 1865 on Mauritius and on Rodrigues and in the late 20th century on Réunion. However, for both Mauritius and Rodrigues, the documented fossil record initially was biased toward larger, non-passerine bird species, especially the dodo Raphus cucullatus and solitaire Pezophaps solitaria. This paper provides a synopsis of the fossil Mascarene avifauna, which demonstrates that it was more diverse than previously realised. Therefore, as the islands have suffered severe anthropogenic changes and the fossil record is far from complete, any conclusions based on present avian biogeography must be viewed with caution.

Abstract Poteat, Monica Deshay
ABSTRACT POTEAT, MONICA DESHAY. Comparative Trace Metal Physiology in Aquatic Insects. (Under the direction of Dr. David B. Buchwalter). Despite their dominance in freshwater systems and use in biomonitoring and bioassessment programs worldwide, little is known about the ion/metal physiology of aquatic insects. Even less is known about the variability of trace metal physiologies across aquatic insect species. Here, we measured dissolved metal bioaccumulation dynamics using radiotracers in order to 1) gain an understanding of the uptake and interactions of Ca, Cd and Zn at the apical surface of aquatic insects and 2) comparatively analyze metal bioaccumulation dynamics in closely-related aquatic insect species. Dissolved metal uptake and efflux rate constants were calculated for 19 species. We utilized species from families Hydropsychidae (order Trichoptera) and Ephemerellidae (order Ephemeroptera) because they are particularly species-rich and because they are differentially sensitive to metals in the field – Hydropsychidae are relatively tolerant and Ephemerellidae are relatively sensitive. In uptake experiments with Hydropsyche sparna (Hydropsychidae), we found evidence of two shared transport systems for Cd and Zn – a low capacity-high affinity transporter below 0.8 µM, and a second high capacity-low affinity transporter operating at higher concentrations. Cd outcompeted Zn at concentrations above 0.6 µM, suggesting a higher affinity of Cd for a shared transporter at those concentrations. While Cd and Zn uptake strongly co-varied across 12 species (r = 0.96, p < 0.0001), neither Cd nor Zn uptake significantly co-varied with Ca uptake in these species. Further, Ca only modestly inhibited Cd and Zn uptake, while neither Cd nor Zn inhibited Ca uptake at concentrations up to concentrations of 89 nM Cd and 1.53 µM Zn. -
