Here in Scotland many of these aspects are being addressed and field stations are working hard today to answer important questions related to climate change, fisheries and environmental impacts of renewable energy. Over the years The Glasgow Natural History Society has both supported and benefitted greatly from our field stations throughout Scotland. Members have participated in excursions, training, research and some have travelled to stations abroad to pursue their interests in natural history. The Glasgow Naturalist regularly publishes studies that have been undertaken at our field stations, as is the case in this edition. So let’s celebrate more than 100 years of biological field stations in Scotland and continue to use and support their future in any way we can.

Report production: July 2009 Consultation: August 2009 SUMMARY Ponds are an important freshwater habitat that has been shown to play a key role in maintaining biodiversity at landscape level. However, ponds are also vulnerable to environmental degradation and there is evidence that, at a national level, pond quality is declining. In 2007, the biodiversity importance of ponds was recognised when high quality ponds (Priority Ponds) were added to the list of UK Biodiversity Action Plan (BAP) Priority Habitats.

ZooKeys 100: 517–532. doi: 10.3897/ zookeys.100.1543 Abstract This paper summarizes the current knowledge on winter active Carabidae in Central and Northern Eu- rope. In total 73 winter active species are listed, based on literature and own observations. Ground beetles are among the three most numerous Coleoptera families active during the autumn to spring period. The winter community of Carabidae is composed both of larvae (mainly autumn breeding species) and adults, as well as of epigeic species and those inhabiting tree trunks. Supranivean fauna is characterized by lower species diversity than the subnivean fauna. The activity of ground beetles decreases in late autumn, is lowest during mid-winter and increases in early spring.

Forensic entomology can help to estimate the time elapsed since death by studying the necrophagous insects collected on a cadaver and its surroundings. In this paper forty eight species (369 specimens) are listed that belong to seven families: Silphidae (3 species), Staphylinidae (6 species), Histeridae (11 species), Anobiidae (4 species), Cleridae (6 species), Dermestidae (14 species), and Nitidulidae (4 species).

    Sand pit for Biodiversity at Cep II quarry Researcher: Klára Řehounková Research group: Petr Bogusch, David Boukal, Milan Boukal, Lukáš Čížek, František Grycz, Petr Hesoun, Kamila Lencová, Anna Lepšová, Jan Máca, Pavel Marhoul, Klára Řehounková, Jiří Řehounek, Lenka Schmidtmayerová, Robert Tropek Březen – září 2012 Abstract We compared the effect of restoration status (technical reclamation, spontaneous succession, disturbed succession) on the communities of vascular plants and assemblages of arthropods in CEP II sand pit (T řebo ňsko region, SW part of the Czech Republic) to evaluate their biodiversity and conservation potential. We also studied the experimental restoration of psammophytic grasslands to compare the impact of two near-natural restoration methods (spontaneous and assisted succession) to establishment of target species. The sand pit comprises stages of 2 to 30 years since site abandonment with moisture gradient from wet to dry habitats. In all studied groups, i.e. vascular pants and arthropods, open spontaneously revegetated sites continuously disturbed by intensive recreation activities hosted the largest proportion of target and endangered species which occurred less in the more closed spontaneously revegetated sites and which were nearly absent in technically reclaimed sites. Out results provide clear evidence that the mosaics of spontaneously established forests habitats and open sand habitats are the most valuable stands from the conservation point of view. It has been documented that no expensive technical reclamations are needed to restore post-mining sites which can serve as secondary habitats for many endangered and declining species. The experimental restoration of rare and endangered plant communities seems to be efficient and promising method for a future large-scale restoration projects in abandoned sand pits.

  • Larval Omnivory in Amara Aenea (Coleoptera: Carabidae)
    Eur. J. Entomol. 100 : 329-335, 2003 ISSN 1210-5759 Larval omnivoryAmara in aenea (Coleoptera: Carabidae) Karel HŮRKA and V ojtěch JAROŠÍK Department ofZoology, Charles University, Viničná 7, CZ-128 44 Praha 2, Czech Republic; e-mail: [email protected] Key words. Carabids, Amara aenea, larval diet, life histories, seed predation Abstract. The duration of development, survivorship and adult size were compared for the larvae of Amara aenea reared in the first generation on pure diets of seeds ( Stellaria media, Capsella bursa-pastoris, Tussilago farfara, Plantago major, Urtica or dioica, Potentilla argentela), or a pure diet of yellow mealworms (Tenebrio molitor larvae), and on a mixed diet of seeds and mealworm larvae (T. molitor, S. media and C. bursa-pastoris). To ascertain any long-term effects of pure diets, the beetles were reared on the same pure diet for several generations, or on different pure diets in different generations. The hypothesis that the larvae are primary omnivorous was tested. The evidence that the larvae of A. aenea are primary omnivorous was obtained by revealing that the larvae reared on the mixed diet of insects and seeds survived better, and developed faster in larger adults than those reared on the pure diets of seeds or insects. When the beetles were reared on the same pure diet for several generations, survivorship, and in most cases also the duration of development, did not change. However, when the beetles were reared on a different pure diet each generation, survi­ vorship significantly decreased in successive generations. INTRODUCTION Recently, an investigation of nine closely related The adults of the genus Amara Bonelli (Coleoptera: Amara species suggested that their larvae can be divided Carabidae) are generally considered granivorous, since into granivorous, omnivorous and insectivorous forms many have been observed feeding on flower heads or (Saska & Jarošík, 2001).
