Challenges and science-based implications for modern management and conservation of European ungulate populations

Abstract: Wildlife management systems face growing challenges to cope with increasingly complex interactions between wildlife populations, the environment and human activities. In this position statement, we address the most important issues characterising current ungulate conservation and management in Europe. We present some key points arising from ecological research that may be critical for a reassessment of ungulate management in the future.

Growing scattered broadleaved tree species in Europe in a changing climate: a review of risks and opportunities

Abstract: Summary Scattered broadleaved tree species such as ashes ( Fraxinus excelsior L. and Fraxinus angustifolia Vahl.), black alder ( Alnus glutinosa (L.) Gaertn.), birches ( Betula pendula Roth. and Betula pubescens Ehrh.), elms ( Ulmus glabra Huds., Ulmus laevis Pall. and Ulmus minor Mill.), limes ( Tilia cordata Mill. and Tilia platyphyllos Scop.), maples ( Acer campestre L., Acer platanoides L. and Acer pseudoplatanus L.), wild service tree ( Sorbus domestica L. and Sorbus torminalis L. Crantz), walnuts ( Juglans regia L., Juglans nigra L. and hybrids) and wild cherry ( Prunus avium L.) are important components of European forests. Many species have high economic, environmental and social values. Their scattered distributions, exacerbated in many cases by human activity, may make them more vulnerable to climate change. They are likely to have less ability to reproduce or adapt to shifting climate space than more widespread species. The general impacts of climate change on these scattered species are reviewed. Some specifi c risks and opportunities are highlighted for each species, although there is considerable uncertainty and therefore, diffi culty in quantifying many specifi c risks and/or impacts on scattered broadleaved tree species.

Nematicidal Activity of Plant Essential Oils against Bursaphelenchus xylophilus (Nematoda: Aphelenchoididae)

Abstract: The nematicidal activity and poisoning symptoms of 88 plant essential oils against Bursaphelenchus xylophilus were examined by an immersion bioassay. Results were compared with those of three trunk-injection nematicides: fenitrithion, levamisol hydrochloride, and morantel tartrate. As judged by 24 h LC50 values, cinnamon bark oil (0.12 mg/ml) was the most effective nematicide, followed by coriander herb oil (0.14 mg/ml). Potent nematicidal activity was also observed with lemongrass, oregano, thyme red, and clove bud oils (LC50, 0.57-0.88 mg/ml). Fenitrothion was ineffective (LC50, > 10 mg/ml). In typical poisoning symptoms in B. xylophilus, these essential oils exerted rapid nematicidal action and the nematodes killed usually showed an extended shape, whereas levamisole hydrochloride and morantel tartrate usually exhibited semicircular and coiling shapes, respectively. The essential oils described merit further study as botanical nematicides for the control of pine wilt disease caused by B. xylophilus.

Ecology and silviculture of silver fir (Abies alba Mill.): a review

Abstract: Silver fir (Abies alba Mill.) is one of the most valuable conifer trees in Europe for historical and economic reasons. Growing interest in the species, along with the recognition that silver fir was subjected to inappropriate silvicultural measures during the 20th century due a lack of understanding of its ecology, have spurred recent studies from various disciplines which have yielded new insights into the gene ecology, history, ecology, structure and dynamics of fir populations. In this paper, we provide a multidisciplinary, synoptical review discussing the prospects for silver fir forestry in the 21st century. We describe the main characteristics of the history and ecology of silver fir, with a particular emphasis on gene ecology and the structure and dynamics of fir populations with respect to mixed stands and fir management. Fir is a fundamental species for maintaining high biodiversity in forested ecosystems because of its shade tolerance, plasticity to environmental conditions and ability t...
