AbstractWe surveyed occurrence and activity of large and medium-sized mammals on three experimental short-rotation coppice (SRC) and three afforestations by camera trapping. Both habitat types were surveyed simultaneously in spring. Additional wintertime surveys were performed on the SRC to consider seasonal aspects of habitat utilisation. In spring, SRC and afforestations were predominantly used by the same species. European hare (Lepus europaeus) and roe deer (Capreolus capreolus) were the most active species across all sites. Additionally, the European rabbit (Oryctolagus cuniculus) showed intense activity on one SRC site. Activity of carnivorous and omnivorous species was comparatively low in both habitat types, but even lower on the SRC. The only forest-associated species (European badger Meles meles), detected on all afforestations, was absent from the SRC. In winter, the surveyed SRC were used by the same species as in spring. Most species showed similar activity on the SRC in both seasons. We conclude that small-scale and structurally diverse SRC provide suitable habitat, in different seasons, especially for herbivorous mammals associated with farmland and forest-ecotones rather than forest species. The extent to which our results can be generalised to large-scale commercial SRC is unclear. However, the results indicate that SRC can be managed in a manner compatible with wildlife and may then have a habitat function for mammals comparable to that of young afforestations. Creation of within-plantation heterogeneity can be a suitable measure to improve habitat quality and should, therefore, be considered in the design and management of SRC.

AbstractWinter body mass of the European hare Lepus europaeus Pallas 1778 was analyzed with a special focus on changes induced by handling. Data were obtained from large scale translocation (net catchments) during 1960–1980 in Poland. The influence of handling was compared using the mass of first-time captured and repeatedly-captured hares, and, in case of repeated capture, individuals’ mass changes were investigated. The average body mass ranged from 2.1 kg to 5.0 kg. Generally, fewer factors influenced the hare’s body mass than expected. Body mass was related to age and winter precipitation, while the date of catching, sex and temperature did not have an effect. Body mass of first-captured hares were significantly higher than the re-captured ones (3.99±0.42 vs. 3.88±0.48, mean ±SD). Body mass change between captures was related to the date of the first capture, and the duration between the first capture and re-capture. Following the initial capture, a slight (2.8±2.6), but significant decrease in body weight occurred. Thus, the handling of hares should be used with caution during studies or management of the species.

The large-scale establishment of short-rotation coppice requires widespread acceptance of all stakeholders concerned, depending on positive attitudes towards short-rotation coppice. Of special importance are the decision makers of agricultural enterprises as they are the ones who determine the use of their land property. The attitudes of nature conservation associations influence the current condition of opinions on short-rotation coppice in society. Based on two surveys with a low number of farmers and including members of the nature conservation associations of the regions Freiberg (Saxony) and Schradenland (Brandenburg), attitudes were assessed towards short-rotation coppice and their management on agricultural land. These surveys had explorative character and the results do not allow any generalisation. It shows that economic and technological aspects are the most relevant to farmers. Concerns of nature conservation associations refer primarily to ecological points of view. The obtained results form the basis for further surveys, which will follow representative sampling.

Characterization of suitable habitat for settlement of juvenile flatfish is important for the management of nursery areas. Food availability is one important determinant of habitat quality that can affect the condition and growth, and thus survival, of flatfish. Spatial and temporal variation in diet has been widely studied for several species of flatfish. However, levels of intraspecific variation in diet at small spatial scales are relatively unknown, with most studies focusing only on large scale variability. This study investigates how diet, growth and condition of juvenile plaice, Pleuronectes platessa, varies over two spatial scales (10s of kilometres and 100s of metres). Juvenile plaice were collected from three beaches and from three replicate hauls on each beach using a beach seine in September 2007 and 2008. Gut content analyses of 108 juvenile plaice within the size-range of 70–90 mm were carried out. Diet composition in plaice guts differed among beaches and hauls suggesting that food abundance and availability differed at both spatial scales. A significant positive correlation was observed between a morphological condition index and the prey diversity in the gut. This suggests that fish which specialize on a limited number of prey items (perhaps due to a greater abundance of certain prey) may do better than fish which feed on a wide range of prey types. Significant differences in condition were observed between hauls and between beaches, while recent and total otolith growth varied between beaches but not between hauls. The results highlight the importance of considering small scale variation when attempting to link habitat quality to feeding, growth and condition of juvenile flatfish.

The lesser grison (Galictis cuja), a poorly known mustelid of southern South America, has been described as a catholic feeder living close to water. Consequently, the potential exists for competition with the recently introduced American mink (Mustela vison). Nonetheless, like most ferrets the lesser grison can be a specialized mammal hunter, in which case it could benefit from introduced mammalian prey (the European hare, Lepus europaeus, and European rabbit, Oryctolagus cuniculus). The diet and trophic position of the lesser grison in Argentinean Patagonia are described in order to discuss the potential effects of introduced mammalian species on grison populations. Mammals (mainly native rodents and introduced lagomorphs) occurred in 100% of the feces and represented 95% of the biomass consumed. In one site, European hares and rabbits reached a combined 66% of biomass consumed, whereas in the other site rabbits were scarce or absent and lagomorphs represented 35% of the biomass consumed. We postulate that lesser grison populations in Patagonia have benefited from the introduced lagomorphs. On the other hand, lesser grisons frequently occupied river valleys, but did not rely on aquatic or semiaquatic prey. Hence, hunting-habitat preference segregates this mustelid from the American mink (Mustela vison), which consumes a catholic diet in which aquatic species usually predominate.
