Holarctic Region

Distribution and habitat preferences of species of Chaoboridae in the Holarctic Region are described. Coexistence of larvae of different Chaoborus species in various water bodies reflects differences in geographical distribution, habitat preference, and phyletic relationships. Extant sister species with similar habitat preferences are allopatric whereas those with differences may be sympatric. This suggests that the development of ecological divergence must historically precede coexistence of the immatures of species. Species which coexist often differ markedly morphologically and are not immediately related phylogenetically.Corethrella and Chaoborus (Sayomyia) species that occur in the Holarctic Region and Chaoborus pallidus may have southern, tropical phyletic affinities. Distributions of some North American chaoborids suggest the presence of ecological barriers in northwestern U.S.A. that prevent southern extensions of the ranges of boreal species.

Abstract A description is provided for Coccomyces papillatus. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: The ecology of this fungus is completely unknown. SHERWOOD (1980) noted strong similarities with Coccomyces strobi (IMI Descriptions No. 1292), which is known to occur on brittle dead attached twigs of native North American five-needled pines in North America and some European countries to which they have been introduced. This habitat is often associated with endobionts involved in self-pruning ecosystems which later fruit on dead twigs, best exemplified by Colpoma quercinum on Quercus and C. crispum on Picea (IMI Descriptions Nos 942. 1333), and Therrya fuckelii and T. pini on Pinus (IMI Descriptions Nos 1297, 1298) and it is tempting to speculate that C. papillatus too will prove to occupy this sort of niche. HOSTS: Pinus wallichiana (twig). GEOGRAPHICAL DISTRIBUTION: ASIA: Pakistan. TRANSMISSION: Not known. Presumably by air-borne ascospores released in humid conditions.

Leptoclinides faeröensis Bjerkan (1905) is a little-known boreal species which has been found only in the Atlantic Ocean (Fig. I). The most northerly record is from a little south of Spitzbergen, the most southerly from 37° 08' N., off the North American coast. It occurs on the coast of Norway and in the Faeroe Islands, but it has not been reported nearer to Plymouth than these two localities. Most records are from deepish waters, though it occurs in the sublittoral zone along the Norwegian coast. It was in this zone, at Looe Island (50' 20' 24“ N., 4 °26' 53” W.) near Plymouth, that we found a specimen of this species growing on a rock about 80 cm. below O.D.—just sufficiently low for it to remain covered by a few centimetres of water at the lowest tide of the year, the equinoctial spring tide.

<p>Shallow water bodies dominate the areal extent of continental waters and host a proportion of biodiversity higher than the percentage of Earth’s surface they cover. <em>Daphnia</em> is a key component of small aquatic ecosystems food webs. Here we present the result of a survey in 24 ponds located in the core of Po river Basin, to assess the actual spreading of <em>Daphnia</em> species in one of the most productive areas of the Northern hemisphere. By using diagnostic genetic markers (<em>12S rRNA </em>and <em>ND5 </em>genes) we identified five <em>Daphnia</em> species: <em>D. ambigua</em>, <em>D. curvirostris</em>, <em>D. longispina</em>, <em>D. obtusa</em> and <em>D. pulex </em>in fourteen ponds. Additional analyses of two nuclear genes (<em>LdhA</em> and <em>Rab4</em>) revealed that <em>D. pulex</em> in the study area is native European strain. In opposite, <em>D. ambigua</em> shared haplotype with the North-Eastern American lineage that was introduced to Europe by long-distance dispersal. In the Po river Basin we identified a highly divergent lineage of <em>D. longispina </em>group that formed a clade with individuals from northern European Russia and might represent a new <em>Daphnia </em>species. <em>Daphnia</em> species in the Cremona province have European origin, except for <em>D. ambigua</em> which is a North American species spreading across Europe. Future attention will require monitoring of invasive species, particularly <em>D. ambigua</em> and the North American invasive clone of <em>D. pulex </em>that is already present in Northern Italy. </p>

Species composition of desmid algae and their habitat preferences in water bodies of Ekaterinburg city were studied during the 2013–2017. Thirty-seven species and subspecific taxa which belong to 12 genera and 2 families were identified, of which 17 species are new for the eastern macroslope of the Middle Urals. Canonical correspondence analysis, which was performed to reveal habitat preferences, demonstrates that the majority of analyzed species prefer quarry lakes, ponds and overgrown lake shores, contrary to fens and rivers.

Malpelo Island

The Colombian leaf-toed gecko (Phyllodactylus transversalis) is the least known reptile species of Malpelo Island (Eastern Tropical Pacific). In the 37 years since its original description, no single study strictly dedicated to this species has been conducted. With the goal of providing information on the ecology and population size of this gecko, data collected during two visits to the island are presented. Behavior and reproduction were studied by following individuals during the night and by searching for hidden individuals and eggs during the day. Population’s density and habitat preferences were estimated by classifying the island’s surfaces into four types and counting geckos inside those habitats within band transects. General morphological measurements of geckos were performed as reference points for future comparisons. Phyllodactylus transversalis lays its eggs in narrow crevices of rocks, apparently communally. Reproduction seems to take place during most of the year, probably associated with the peak breeding season of seabirds. Although conspecifics shared shelters during the day, densities during the night suggest no apparent habitat preference for foraging. Population size of this species was estimated at approximately 114000 individuals.

The genus Physalaemus is widely distributed over South America, east of Andes. Physalaemus cicada belongs to the Physalaemus cuvieri group, is widely distributed over the Caatinga and is usually found in lentic and/or temporary water bodies. Herein, we extend its geographical distribution providing the first record of Physalaemus cicada for Piauí state, in the municipality of Picos.

AbstractThe North American species of the genera Arpedium Erichson, and Eucnecosum Reitter are revised. Five species are recognized, the holarctic species E. brachypterum (Gravenhorst), E. tenue (LeConte) and E. brunnescens (J. Sahlberg), the transcontinental boreal species A. cribratum Fauvel and the eastern United States species A. schwarzi Fauvel.Lectotypes are designated for E. brachypterum, A. cribratum, A. angulare Fauvel (= A. cribratum), and A. schwarzi. The following new synonymy is established, Arpedium norvegicum var. sallasi Munster and Eucnecosum meybohmi Lohse (= E. tenue) and Arpedium angulare Fauvel and A. columbiense Hatch (= A. cribratum). All genera and species are described and illustrated with scanning electron photomicrographs and line drawings, four maps showing the North American distribution of each species are provided, and keys are presented to aid in the identification of all the species as well as the European species Arpedium quadrum (Gravenhorst). All available records and biological data for the species are summarized.The use of the generic name Eucnecosum Reitter is discussed and the transfer of brachypterum, tenue, and brunnescens from Arpedium to this genus by Lohse is confirmed.
