Site Synopsis
SITE SYNOPSIS SITE NAME: CLOONLOUM MORE BOG NHA SITE CODE: 002307 Cloonloum More Bog NHA is situated approximately 5 km south-west of Tulla, mainly in the townlands of Cloonloum More and Clooncool in Co. Clare. The site comprises a raised bog that includes both areas of high bog and cutover bog. The north-western margin of the site is bounded by a road, while the other margins are bounded by areas of cutover and grassland. The raised bog consists of one crescent-shaped lobe. There is an absence of permanent pools and hummocks/hollows on the high bog and there are large areas of cutover. This raised bog is of particular interest as it is one of the few remaining raised bogs in the county. A small lake, Lough Gara, is included at the south of the site. Much of the high bog vegetation is typical of raised bogs in Ireland, consisting of Ling Heather (Calluna vulgaris), Cross-leaved Heath (Erica tetralix), White Beak- sedge (Rhynchospora alba) and Deergrass (Scirpus cespitosus). Bog-rosemary (Andromeda polifolia) is found on this bog, although not in abundance. The bog moss (Sphagnum spp.) cover is quite variable, with species such as S. capillifolium, S. magellanicum and S. fuscum. The cutover areas surrounding the bog have become dominated by Purple Moor-grass (Molinia caerulea) and Gorse (Ulex europaeus). The lake at the south of the bog is surrounded by the Common Reed (Phragmites australis) and the Bulrush (Typha latifolia). Current landuse on the site consists of peat-cutting around the edge of the high bog, and the drainage associated with this. -
Isles of Scilly
Isles of Scilly Naturetrek Tour Report 14 - 21 September 2019 Porthcressa and the Garrison Red Squirrel Grey Seals Birdwatching on Peninnis Head Report & Images by Andrew Cleave Naturetrek Mingledown Barn Wolf's Lane Chawton Alton Hampshire GU34 3HJ UK T: +44 (0)1962 733051 E: [email protected] W: www.naturetrek.co.uk Tour Report Isles of Scilly Tour participants: Andrew Cleave (leader) plus 12 Naturetrek clients Summary Our early-autumn week on the Isles of Scilly was timed to coincide with the bird migration which is easily observed on the islands. Our crossings to and from Scilly on Scillonian III enabled us to see seabirds in their natural habitat, and the many boat trips we took during the week gave us close views of plenty of the resident and migrant birds which were feeding and sheltering closer to shore. We had long walks on all of the inhabited islands and as well as birds, managed to see some marine mammals, many rare plants and some interesting intertidal marine life. Informative evening lectures by resident experts were well received and we also sampled lovely food in many of the pubs and cafés on the islands. Our waterfront accommodation in Schooners Hotel was very comfortable and ideally placed for access to the harbour and Hugh Town. Day 1 Saturday 14th September We began our trip in Penzance harbour where we boarded Scillonian III for the crossing to Scilly. Conditions were fine for the crossing and those of us up on deck had good views of seabirds, including Gannets, Fulmars and winter-plumage auks as we followed the Cornish coast and then headed out into the Atlantic. -

Abstract The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is one of the most polyphagous herbivores feeding on cell contents of over 1100 plant species including more than 150 crops. However, despite its important pest status and a growing understanding of the molecular basis of its interactions with plant hosts, knowledge of the way mites interface with the plant while feeding and the plant damage directly inflicted by mites is lacking. Likewise, while the use of the reverse genetic tools in plants facilitated our understanding of the establishment of defense mechanisms against spider mite herbivory, such tools are lacking for spider mite, preventing the expansion of functional analysis to both sides of the interacting organisms. -

'I ii Abstract Soil:plant relationships of species-rich Molinia caerulea dominated communities of the Culm Measures, North Devon, with special reference given to phosphorus cycling. Margaret Jane Goodwin A semi-natural community known locally as Culm grassland in Devon and N. E. Cornwall is under threat from agricultural improvement, abandonment and inappropriate management In the last fifty years 87% of the original area has been lost. Funher loss may be prevented by ~ examination of the factors that influence the plant community and how they may be manipulated by management. Thus the research described in this thesis addressed the soil conditions and the plant communities, with particular reference to phosphorus cycling. In 1992 a preliminary characterisation of soil nutrient and water conditions, and species composition was conducted on a pristine Culm grassland, an improved grassland and a formerly abandoned Culm grassland. -

Sites of Importance for Nature Conservation in Bridgend County
Sites of Importance for Nature Conservation in Bridgend County Borough Council SINC number:MG-1-M SINC name: Caerau West Grid reference: SS 846 938 Area (hectares): 62.09 Survey date: 06/09/2011 Surveyor name: Rebecca East Summary description A large dry acid grassland site with purple moor grass pasture in the more low lying areas. Species diversity increases in the wetter areas. The site also includes areas of dense bracken. Qualifying features Dry acid grassland Secondary features Purple moor grass and rush pasture Potential value/ unconfirmed features The site may be suitable for a range of invertebrate and bird species for feeding and possibly ground nesting. Smaller reptile species may be found here and amphibians may use the pools of standing water for breeding. Current condition and management (including problems and opportunities for biodiversity) Sheep, cattle and horses graze the area, fairly tightly in places which may limit the biodiversity value. Himalayan balsam is present in small parts of the site, particularly where past disturbance or tipping has taken place. The site may benefit from bracken control and limiting livestock numbers. Recommendations for future management: • Consider reducing grazing pressure on grassland • Removal of tipped material. • Control of invasive species. • Management of bracken. Additional information: A few areas of similar habitat beyond the SINC boundary could be surveyed in the furture with a view to designation.

Tetranychus Lintearius Dufour, 1832, Is a Valid Species (Acar.) Notulae Ad Tetranychidas 11
90 ENTOMOLOGISCHE BERICHTEN, DEEL 27, 1.V.1967 Tetranychus lintearius Dufour, 1832, is a valid species (Acar.) Notulae ad Tetranychidas 11 by G. L. VAN EYNDHOVEN Zoölogisch Museum, Amsterdam It has always been a problem whether or not Tetranychus lintearius Dufour, 1832, should be considered as a separate species. It is the type species of the genus Tetranychus Dufour, 1832, but nevertheless very insufficiently known. Owing to this fact the species has usually been synonymized with Tetranychus urticae C. L. Koch, 1836 ( = Tetranychus telarius (L., 1758) in the sense of Pritchard & Baker, 1955). Dufour described the mite in 1832 with the following characteristics: “Tetranychus lintearius, Tétranyque linger. Ovatus obtusus, ruber, pedibus dilutioribus ; dorso pedibusque pilis albidis longis distinctis. Hab. gregarius in arbustis quos telis vestit.” Two figures complete this Latin diagnosis. The additional description and the notes on the biology are written in French. Dufour found the specimens on the “ajonc”, the gorse (Ulex europaeus L.), at the environs of Saint Sever, Landes, France. Shrubs with a diameter of several feet were entirely enveloped by a large, milkwhite web. Although Dufour was aware of the existence of other spinning mites (Trom- hidium socium, telarium and tiliarium, p. 280), he had never seen them and so he thought his species to be entirely new. As he believed the legs to end in four little claws, he composed for his new genus the name Tetranychus, and as he was highly impressed by the heavy spinning, he introduced as species name the word linte¬ arius, meaning a merchant of linens or a linen-weaver. -
