Amauronematus Compactus Bogacheva and A © Entomologica Fennica. 12 December 1994 Amauronematus compactus Bogacheva and A. harpicola Bogacheva (Hymenoptera, Tenthredinidae) from the Polar Urals Aleksej G.

Fennica 5:135-138. In a list of sawflies from the Polar Urals, I. A. Bogacheva briefly described and named the larvae of two Amauronematus species attributed to Zhelokhovtsev. Reared specimens with Zhelokhovtsev' s identification labels can be considered syntypes. Lectotypes of Amauronematus compactus Bogacheva, 1977 and A. harpicola Bogacheva, 1977 are designated and described. Aleksej G.

Changes in vegetation structure can alter the physical habitat structure, thermal environment, and food available to arthropods, which play an important role in the structure and functioning of Arctic ecosystems. Not only do they provide key ecosystem services such as pollination and nutrient cycling, they are an essential food source for migratory birds. In this study I examined the relationships between the abundance, diversity, and community composition of arthropods and the height and cover of several shrub species across a tundra-shrub gradient in northwestern Alaska. To characterize nestling diet of common passerines that occupy this gradient, I used next-generation sequencing of fecal matter. Willow cover was strongly and consistently associated with abundance and biomass of arthropods and significant shifts in arthropod community composition and diversity.

The actual arthropod taxa comprising the chick diet are however rarely known, complicating assessments of ecological interactions. In this study, I identified the nestling diet of Svalbard snow bunting (Plectrophenax nivalis) for the first time. Faecal samples of snow bunting chicks were collected in Adventdalen, Svalbard in the breeding season 2018 and analysed via DNA metabarcoding. Simultaneously, the availability of prey arthropods was measured via pitfall trapping. The occurrence of 32 identified prey taxa in the nestling diet changed according to varying abundances and emergence patterns within the tun- dra arthropod community: Snow buntings provisioned their offspring mainly with the most abundant prey items which were in the early season different Chironomidae (Diptera) taxa and Scathophaga furcata (Diptera: Scathophagidae), followed by Spilogona dorsata (Diptera: Mus- cidae).

    Newsletter of the Invertebrate Conservation & Information Network of South Asia & the Invertebrate Special Interest Group, CBSG, South Asia Vol. 8 No. 1, July 2005 Conservation Assessment and Management Plan Workshop for Freshwater Biodiversity of Pakistan, 13-17 December, 2004 A Conservation Assessment and Management Plan (C.A.M.P) workshop for Freshwater Biodiversity for Pakistan was organised by the IUCN Pakistan in association with CBSG South Asia, South Asian Invertebrate Specialist Group and Zoo Outreach Organisation from 13-17 December 2004. The objective of the workshop is to assess the status of selected freshwater fauna such as Fishes, Crustaceans (crabs), Molluscs (snails), and Odonates (dragonflies and damselflies) in the wild. Dr. Abdul Latif Rao, Country Representative, IUCN Pakistan, Dr. B. A. Wani, Inspector General, Ministry of Forests, Government of Pakistan, Dr. Kashif M. Sheikh, Head, IUCNP and Sally Walker, Convenor, CBSG South Asia were on the dias for the inaugural function. Short presentations were given by them and also by Dr. Nasim Akhtar, Dy. Dir. General, Animal Sciences Institute (Freshwater Resources and its Conservation in Pakistan), Sanjay Molur, Co chair, Reinrtroduction Specialist Group, South and East Asia and Red List Specialist, and by Dr. B.A. Daniel, Co chair, South Asian Invertebrate Specialist Group. The IUCN SSC Freshwater Biodiversity Programme identified the groups such as Freshwater fishes, Crustaceans (crabs), Molluscs (snails), and Odonata (Dragonflies & Damselflies), so the participants agreed to prioritise these groups of their five day assessment. Before dividing into working groups information of a well-known species, the Himalayan Maseer (Tor macraleupatus) of the Family Ciprinidae, was tried and a taxon data sheet was filled in as an example with all participants contributing information.

[email protected] ABSTRACT This paper is a review of the history of the introduction of arthropod herbivore species to Iceland since the beginning of the 20th century. A total of 27 new arthropod herbivore species on trees and shrubs have become established in Iceland during this period. One of the introduced pest species, the pine woolly aphid, has been considered to be the major cause of the almost total eradication of the introduced Scots pine in Iceland. The rate of introduction was found to be highest during warm periods. Outbreaks of pests in birch woodlands were also found to be most severe during warm periods. Other pest species have shown changes in outbreak patterns since 1990. The consequences of these findings for isolated native forest ecosystems and a growing forest resource in Iceland are discussed.

EXPERT CONTACTS Please contact [email protected] for details. D. SPECIES OF CONSERVATION CONCERN Listed species None – insufficient data. Other species Amauronematus abnormis . An arctic species known from only two sites in the Cairngorms Plateau. The host plant, Salix herbacea is widespread, and so the limiting factor is almost certainly climatic. A. abnormis requires very cold climatic conditions that ensure snow patches lie until late summer. This species is likely to be effected by warming climatic conditions. No other species are known to be of conservation concern based upon the limited information available. Conservation status will be more thoroughly assessed as more information is gathered. Host plants Many species of sawfly are monophagous, with several high altitude speces relying on single Salix species such as S. arbuscula , S. lapponum and S, myrsinites , which have suffered serious declines in range and density since recording began 150 years ago. These declines have probably been caused by increased grazing pressure. In many cases, the rarity of the sawfly is therefore already determined by the rarity of its host plant. 1 E.
