Species of Lissothrips and Williamsiella from mosses and lichens in Australia and New Zealand (Thysanoptera, Phlaeothripinae)

Species of Lissothrips and Williamsiella live in association with mosses and lichens. Their gut contents are commonly blue-green, suggesting that they possibly feed on blue-green algae. Three species of Lissothrips are known from New Zealand, of which two are here recorded from Australia together with six new species. Williamsiella is recorded from Australia for the first time, with one new species.

Three new club-mosses from Panama

In a previous paper relating to a singular new fern (Polypodium podocarpum) from Panama, I have described very briefly the mountian (sp) region above David in the province of Chiriqui, and have referred in particular to a most interesting collecting trip of three days which I took from El Boquete over "Holcomb's trail" along the Rio Caldera to "Camp I" and to the summit of the Continental Divide a few miles farther on...(Document contains 9 pages)

Extent and biomass of the aquatic chariphytes and mosses in Lake Sevan [Translation from: Rasprostranenie i biomassa kharovykh vodoroslei i mkha v os. Sevan, 1951]

This study focusses on the plants in the open parts of the lake - mostly aquatic charophytes and mosses, in what are called in Lake Sevan (Armenia), the ”zones of chara and moss”. Distribution and other ecological conditions are reviewed. Quantity of chara in the littoral zone of lake Sevan is provided

West Middlands Mosses cSAC, Wybunbury Moss and Abbots Moss

This is the report on Habitats Directive, the Review of Consents Stage 1 and 2 by the Environment Agency of the West Midlands Mosses cSAC, Wybunbury Moss and Abbots Moss. The Habitats Directive has the main aim to promote the maintenance of biodiversity by defining a common framework for the conservation of wild plants and animals and habitats of community interest. The Directive establishes a European ecological network known as "Natura 2000". The network comprises Special Areas of Conservation (SAC) and Special Protection Areas (SPA). In the section on Stage 1 or Screening Process of the Habitat Directive, it is identified the likely impacts upon the West Midlands Mosses cSAC, Wybunbury Moss and Abbots Moss of a project, plan or activities, either alone or in combination with other projects, plans or activities, and considers whether these impacts are likely to be significant. In the section on Stage 2 or Appropiate Assessment of the Habitat Directive, it is considered the impact on the integrity of the West Midlands Mosses cSAC, Wybunbury Moss and Abbots Moss of the projects, plans or activities, either alone or in combination with other projects, plans or activities, with respect to the site’s structure and function and its conservation objectives. Additionally, where these are adverse impacts, an assessment of the potential mitigation of those impacts. The criteria used in this report to identify relevant projects, plans or activities and their impacts are water quality discharge consents, waste management licences, abstraction licences, Integration Pollution Control (IPC) and Integrated Pollution Prevention Control (IPPC) permits. Proformas, hydrogeological and GIS maps are included in the review.

Meres and mosses conservation plan: Rostherne Mere

This is a report on the Conservation Plan for Rostherne Mere. The project primarly involved collating existing information from a variety of sources, supplemented by a limited amount of survey work commissioned for the project, including identification of the surface water catchment, water flows, and land use within the catchment. The section 1 outlines the physical situation of the Site of Special Scientific Interest (SSSI), its geological setting and hydrological regime. A summary of the ecological characteristics, conservation interest and objectives is provided in Section 2, and the issues affecting the site are identified in Section 3. . Operations and mechanisms for addressing the issues are suggested in Section 4, compiled from field visits, information held on file by English Nature and the Environment Agency, and English Nature. The last Section 5 provides a brief summary of the site’s condition and a discussion of the issues and operations suggested. A summary table is provided of the recommended actions for each site. Supporting information on the hydrology and aquatic ecology (where relevant) is provided in appendices.

Newly resolved relationships in an early land plant lineage: Bryophyta class Sphagnopsida (peat mosses).

UNLABELLED: PREMISE OF THE STUDY: The Sphagnopsida, an early-diverging lineage of mosses (phylum Bryophyta), are morphologically and ecologically unique and have profound impacts on global climate. The Sphagnopsida are currently classified in two genera, Sphagnum (peat mosses) with some 350-500 species and Ambuchanania with one species. An analysis of phylogenetic relationships among species and genera in the Sphagnopsida were conducted to resolve major lineages and relationships among species within the Sphagnopsida. • METHODS: Phylogenetic analyses of nucleotide sequences from the nuclear, plastid, and mitochondrial genomes (11 704 nucleotides total) were conducted and analyzed using maximum likelihood and Bayesian inference employing seven different substitution models of varying complexity. • KEY RESULTS: Phylogenetic analyses resolved three lineages within the Sphagnopsida: (1) Sphagnum sericeum, (2) S. inretortum plus Ambuchanania leucobryoides, and (3) all remaining species of Sphagnum. Sister group relationships among these three clades could not be resolved, but the phylogenetic results indicate that the highly divergent morphology of A. leucobryoides is derived within the Sphagnopsida rather than plesiomorphic. A new classification is proposed for class Sphagnopsida, with one order (Sphagnales), three families, and four genera. • CONCLUSIONS: The Sphagnopsida are an old lineage within the phylum Bryophyta, but the extant species of Sphagnum represent a relatively recent radiation. It is likely that additional species critical to understanding the evolution of peat mosses await discovery, especially in the southern hemisphere.
