Inter-annual variation in species composition and richness after coppicing in a restored coppice-with-standards forest

As a man-induced disturbance of forest ecosystems, thinning may affect biodiversity and other related ecological functions including fungal dynamics. In this context, a multidisciplinary EU-Life project was established in 2014 to evaluate the application of selective thinning in two Pinus nigra plantations areas of the Apennines (Monte Amiata and Pratomagno, Tuscany, Italy). Selective thinning had the aim to improve stands stability and growth rates, taking also into account the various components of soil biodiversity (flora, fungi, mesofauna, nematodes, microarthropods and bacteria). Here we present mushroom fruiting patterns previous to treatment in 2014 and the effect following the application of forest management (selective thinning and traditional thinning from below) in 2018. Boxplots were used to graphically represent intra and inter annual variations in species richness and abundance, while Principal Coordinates Analyses and multi-response permutation procedures based on Bray-Curtis dissimilarity matrix were applied to evaluate turnover in species composition before the management and after 4 years. A significant reduction of fungal richness and abundance after 4 years thinning impact was lacking in both study areas, testifying a certain degree of resistance and/or resilience of mushroom fruiting to forest management-related anthropogenic disturbance. Considering each study site separately, Monte Amiata and Pratomagno did not show one uniform trend but differed significantly in their response to management: while in Pratomagno relevant inter-annual differences were present only in a few cases, an underlining significant variation both for species richness and abundance was registered in Monte Amiata for all treatment types among years (inter-annual variation) but not within each year (intra-annual variation). Only in Pratomagno turnover in species composition in selective thinning differed somewhat from the traditional treatment in 2018, showing that a process is underlying but still potentially masked by other variables. Due to the nature of macrofungi, a longer study period (more than 4 years post treatment impact) as well as the application of a more intense forest management, could be necessary to highlight and disentangle any possible trends in fungal fruiting in artificial stands

Black Duck

The results of six annual surveys of waterfowl hunters in New South Wales by mail card are reported. The aims of the survey were to ascertain reported distribution of hunting effort, size and composition of hunters' bags, and state of hunter origin. Hunting effort and waterfowl harvests were highest in southern inland New South Wales. Seasonal bag sizes varied between 15.8 and 27.2 ducks per hunter. Pacific black duck, grey teal and maned duck made up 88.6% of hunters' bags. About half the hunters in New South Wales originated from Victoria. Bag size and species composition, effect of reducing bag size on total harvest, regional bias in hunting effort and harvest, and annual variation in licence sales are discussed.

The feeding habits of Trigla lucerna L. (1758) and Aspitrigla obscura L. (1764) (Pisces: Triglidae), off the coast of the Gulf of Valencia (Spain), were investigated between October 1989 and January 1991. The two species examined in this study appear to have distinct feeding types, based on the species composition of prey and the frequency of occurrence of major food items. Tub gurnard had a more diverse diet and fed mainly on crustaceans (mysids and decapods), teleosts and molluscs, whilst long fin gurnard were less piscivorous and fed mainly on mysids and natantids. No significant differences were found in the annual variation of vacuity coefficient for either species. Diet composition in these species did not show great changes with either season and size of fish. There was little dietary overlap between these two species.

Coppice With Standards

The forests in the Canton of Zurich around 1823 – forest types and tree species Based on early forest management plans from 1823, this paper analyses forest management practices and tree species composition in the public forests of the Canton of Zurich in the early 19th century. Forest type distribution across the canton is reconstructed and detailed tree species composition is shown for 31 communities in the north-western part of the canton. For these communities, we compared the historical tree species composition with modern data from a regional forest inventory. The results show that coppice with standards was the most important forest type in the early 19th century. Tree species composition largely depends on the forest types. The highest diversity in tree species can be found in coppice and coppice-with-standards forests. The analyses reveal no clear relationship between tree species composition and environmental factors such as climate, topography and soil. This leads to the conclusion that in the early 19th century already management had a stronger influence on tree composition than natural conditions. During the last 200 years, tree species composition in the Canton of Zurich changed profoundly. Whereas today's forests are more natural in terms of species composition, they are less diverse in species. Knowing the tree species composition in the past can thus be helpful in conservation projects, e.g. in establishing coppice and coppice-with- standards forests in order to promote rare light-demanding plant and animal species.
