“…Fifteen peaks were found that correspond to at least 15 plant species (24 maximum). Among plant species detected from stools, there were gymnosperms and angiosperms that have been previously reported in moose diet (Dzięciołowski 1974; Morow 1976; Belovsky 1981) by traditional methods (Table 1). One peak (59 bp) was not identified.…”

“…Indeed, Taberlet et al (2007) suggested that the P6 loop will become the marker of choice for degraded DNA and diet studies based on feces (see also Kowalczyk et al 2011; Pompanon et al 2012). As many as 15 different peaks were identified from moose stools that correspond to 15–24 plant species (Table 1 of the Supplementary Material), including gymnosperms and angiosperms that have been previously reported in its diet (Dzięciołowski 1974; Morow 1976; Belovsky 1981). Different plant species were also successfully identified in the roe deer and red deer stool samples (19–32 and 19–29, respectively).…”

“…The majority of these plant species were previously identified as moose food by microscopic examination of their gut contents or by direct observations of herbivores (Dzięciołowski 1974; Morow 1976; Belovsky 1981). Whole DNA was extracted from leaves and buds using Genomic Mini AX Plant (A&A Biotechnology) with elution in 50 μL of QIAGEN nuclease-free water.…”

“…Moose is a concentrate selector, i.e., it needs easily digestible and nutritious food. Its morphological and anatomical structure is adapted for high selectivity (Hofmann 1989), which means that they actively search for the most preferred plant species (Dzięciołowski 1974). Previous studies show that during summer, moose mainly eats herbaceous plants, leaves of trees, and shrubs while winter is dominated by browsing (Dzięciołowski and Pielowski 1975).…”

Fast and efficient DNA-based method for winter diet analysis from stools of three cervids: moose, red deer, and roe deer

Effects of cervid browsing on timber production, especially during winter, lead to economic losses in forest management. The aim of this study was to present an efficient DNA-based method which allows qualitative assessment of the winter diet from stools of moose (Alces alces), roe deer (Capreolus capreolus), and red deer (Cervus elaphus). The preliminary results of the diet composition of the three cervids from Poland were also presented with a special emphasis on moose. The electropherograms of the chloroplast intron trnL (UAA) P6 loop amplification products using g (fluorescence-labeled) and h primers revealed differences in the length of PCR products among various plant species eaten by these herbivores. In addition, the usage of species-specific primers allowed unambiguous identification of different gymnosperms and angiosperms. The preliminary moose diet analysis, based on winter fecal samples from the entire range of moose occurrence in Poland, revealed the presence of 15 to 24 tree, shrub, and herbaceous species. This fast, cost-efficient, and simple method proved also to be reliable for the diet analysis of red deer and roe deer. It may be a valuable tool in forest and conservation management, as well as a way of enhancing ecological studies focusing on the impact of herbivores on the ecosystems and their possible food niche overlap.Electronic supplementary materialThe online version of this article (doi:10.1007/s13364-013-0146-9) contains supplementary material, which is available to authorized users.

. 1994. Moose browsing on pine and willow in the Biebrza Valley, Poland. Acta theriol. 39: 73-82.Utilization of browse supply and moose Alces alces Linnaeus, 1758 browsing intensity in relation to tree height (0.5-3.0 m) were estimated for Scots pine in thickets and willow in willow-birch shrubs. The thickets examined provided different browse resources (0.5, 2.0 and 3.2 t dry wt/ha) and the highest utilization (about 50%) was found in the poorest one (thicket 1). In the willow-birch shrubs the use of browse was high and amounted to 85% of total production in both the winter periods studied. The number and increase of biomass of browsed twigs per stem (or plot) was generally associated with the increase of tree height. Browsing intensity depended on the tree height. Pines of 1.5-1.99 m height were characterized by the greatest browse utilization (76.3%). Moose removed significantly more biomass and twigs from pines growing in the central zone of the thicket 1 than from those growing in the marginal zone. However, in the willow-birch shrubs the utilization of all tree height classes was above 70% of the production and moose browsed not only the last year's growth of shoots but also that of earlier years.
