The intensity of grazing on palatable species can vary depending on the neighboring plants in plant communities. We aimed to search for species whose biomass can have a positive effect on palatable plants near them in a grassland under grazing pressure by sika deer. We selected Iris sanguinea Hornem. as an indicator species of ease of being grazed because it is a palatable and past dominant species before the increase in deer density. We estimated the effects of the biomass of neighboring plant species, soil water content, and distance from the forest edge on the height of I. sanguinea. The height was remarkably and positively affected by the biomass of four graminoid species with larger biomass and slightly positively affected by the biomass of a toxic species. This study suggests that the biomass of less-palatable species may have an important influence on the size of palatable species under grazing pressure by deer. 相似文献

Ehrlichia muris DNA was detected in the blood of sika deer (Cervus nippon yesoensis) by species-specific PCR based on the citrate synthase gene, which was shown to be more sensitive than species-specific PCR based on the 16S rRNA gene. Among 102 deer examined, one deer was positive. Deer may be a possible mammalian reservoir of E. muris. 相似文献

梅花鹿三种保定药物对比实验 总被引:1,自引:0,他引:1
本文通过用静松灵、司可林、眠乃宁三种保定药物保定梅花鹿对比实验,得出:①静松灵一次性给药剂量较大,生产中操作不方便。②司可林一次给药剂量虽小,但有效剂量与致死剂量十分接近,剂量误差易导致鹿死亡。③静松灵和司可林均无有效拮抗药物,且后遗性影响较大。④眠乃宁注射剂量适中,剂量误差不会导致鹿死亡,无后遗性影响。拮抗药物苏醒灵拮抗效果优良,使眠乃宁的应用更安全。 相似文献

东北梅花鹿卵泡发育的显微结构 总被引:1,自引:1,他引:1
为揭示雌性东北梅花鹿的生殖机理提供组织依据,利用光学显微镜观察7只成年东北梅花鹿卵巢的组织结构和卵泡的发育过程,同时利用目镜测微尺和显微照相技术分别对60个原始卵泡、60个初级卵泡、25个次级卵泡、34个三级卵泡和3个成熟卵泡及透明带厚度进行测量和拍照。结果表明,东北梅花鹿卵巢组织也是由生殖上皮、白膜、皮质和髓质构成;皮质部在卵巢的外周,但间质腺不发达;髓质位于皮质深层,分布有较多的血管。卵泡在发育过程中,各级卵母细胞和卵泡的直径差异较大,卵泡和卵母细胞的生长呈双向生长;透明带物质出现于3~4层卵泡细胞包围卵母细胞时;卵泡闭锁发生于卵泡生长的各个时期,主要表现为卵母细胞和卵泡细胞的形态变化,有两种形式;三级卵泡的闭锁过程分为早期、中期和后期3个阶段。 相似文献

In contrast to studies on domestic animals, few reports describe ventricular bands in wildlife, and none in aquatic mammals. Ventricular bands in the endangered Saimaa ringed seal (Pusa hispida saimensis) and the Baltic ringed seal (Pusa hispida botnica) were examined as part of an ongoing research on the comparative anatomy of ringed seal subspecies. The dissections illustrated that a varying number of thin or thick ventricular bands from the papillary muscles to the ventricular walls were visible in the ventricles of all ringed seal specimens examined. The histological appearance of the ventricular bands was characterized by a fibromuscular pattern. 相似文献

The foraging behavior of deer can be influenced by both food availability and the “critical distance” from protective vegetation cover. The effect of the distance from the farm periphery on the risk of forage damage by sika deer was investigated in a public pasture in Tochigi Prefecture in central Japan from May to November 2006 and in May 2007. The risk of forage damage by sika deer, evaluated by deer pellet group density, was compared along three line transects at different distances from the farm periphery (10, 110 and 210 m) and among 18 paddocks at different distances from the farm periphery. Deer pellet group abundance in the line transects did not differ significantly with the distance from the periphery but decreased significantly with the distance from the nearest escape cover. The transect‐based deer pellet abundance was more significantly influenced by other factors such as paddock identity and survey month in a generalized linear model. Deer pellet group abundance in the paddocks showed a significant albeit weak negative correlation with distance from the periphery in May 2007, but not in November 2006. The paddock‐based deer pellet abundance was more influenced by sward height than by the distance from the periphery in a generalized linear model. Furthermore, a high density of deer pellet groups was exclusively observed in the paddock just after pasture renovation. These results show that the foraging behavior of sika deer was influenced partially by the distance from the nearest escape cover but largely by other factors such as herbage quality and seasonality. 相似文献
