The annotated list of hepatics of the Sochi National Park includes 80 taxa. It is based on literature records and identification of 250 specimens collected by the authors. Scapania obcordata (Berggr.) S. W. Arnell and Calypogeia fissa (L.) Raddi var. intermedia (C. E. O. Jensen) Jorg. are new for the Caucasus, 17 taxa are new for Krasnodar Territory, 41 hepatics are reported for the first time for the park. New localities of 3 red-listed European species and of 6 species included in the Red Data Book of Krasnodar Territory are cited, indicating significant conservation value of the reserve.

Abstract The relationship between nest entrance orientation and latitude among ground-nesting passerines was reviewed using published information. Data were collated for seven North American and European species. Pooling within-species comparisons, there was a clear trend from a preference for north-facing nests at lower latitudes to eastward- or southward-facing nests farther north. Orientations differed significantly in eight of 12 cases for which statistical comparison was possible, means differing in the expected direction in six of these cases. These results highlight how the influence of solar radiation on nest microclimate typically delineates preferred nest orientation in these species, i.e., at lower latitudes, the need for shade results in a preference for northward orientations; at mid latitudes, eastward orientations predominate, reflecting a probable balance between the benefits of warmth in the early morning and shade in the afternoon; while at high latitudes, nests may be oriented southward to gain warmth throughout the day.

AbstractThe lichen genus Lecanactis Körb. in Tasmania comprises six species: L. abietina (Ach.) Körb., which is widespread and pan-temperate; L. latispora Egea & Torrente and L. neozelandica Egea & Torrente, both shared with New Zealand and with the former recorded here from the Auckland Islands for the first time; L. mollis (Stirt.) Frisch & Ertz, shared with Victoria and New Zealand; L. aff. dilleniana (Ach.) Körb., a European species recorded provisionally for Tasmania on the basis of several sterile collections; L. scopulicola Kantvilas, which is described here as new to science and apparently a Tasmanian endemic. This new taxon occurs in rocky underhangs and is characterized by a thick, leprose thallus containing schizopeltic acid, and 3-septate ascospores, 19–30 × 4.5–6 μm. Short descriptions and a discussion of distribution and ecology are given for all species. A key for all 11 Australian species of the genus is provided, including L. subfarinosa (C. Knight) Hellb. and L. tibelliana Egea & Torrente, which are recorded for Australia for the first time, and L. platygraphoides (Müll.Arg.) Zahlbr., a first record for New South Wales. Lecanactis spermatospora Egea & Torrente and L. sulphurea Egea & Torrente are also included.

Abiotic Environmental Factors

AbstractThe aim of this review is to summarize the literature knowledge about how abiotic environmental factors and biotic interactions affect the sequentially overlapping longitudinal distribution of Central European species of the net-spinning freshwater caddisfly larvae of the genus Hydropsyche (Trichoptera: Hydropsychidae). In this relation, several physical and chemical parameters of water are discussed, as well as different species-specific traits, behavioural aspects and the interaction of coexisting species. Longitudinal gradients of river networks, especially annual temperature range, flow velocity and the particle size of suspended food material play a crucial role in forming the downstream succession of characteristic species, while increased levels of organic pollution, nutrients, salinity and heavy metals facilitates the presence of more tolerant ones. Several species-specific traits, such as respiration range, net-building frequency, head capsule size or optimal net-building velocity correlate with the position of a given species in the sequence. Coexistence of species with similar ecological demands in the overlapping zones of distribution is facilitated by differences in feeding and net-building habits, microhabitat preferences and staggering life cycles, but complicated at the same time by means of inter- and intraspecific territorial behaviour, such as fighting for the ownership of larval retreats or the practice of stridulation.

Pending the publication, in a paper now in preparation, of an account of the Holothuria of the Plymouth district, and an attempt at a revision of the European species of that group, it has appeared advisable to publish the following short note, with the view of removing one of the most prolific of those sources of error with which the literary history of the Holothuria has come to be burdened.

Microplectron fuscipennis , Zett., appears to be restricted for its host material to the European species of the Tenthredinid genus Diprion , Schrank. It has been recorded from D. sertifer , Geoffr., D. pini , L., D. pallidus , Kl., and, recently, from D. polytomum , Htg. The resting stage larva within the cocoon is attacked, oviposition occurring after the host has been paralysed. The present paper is an account of part of a more extensive programme of work on Microplectron which is being undertaken in view of the promising nature of the parasite and of its introduction into Canada. The biology of the species has been dealt with by Morris and Cameron (1935) and its reactions to changes in the physical environment by the present writer (Ullyett, 1936).
