摘要

摘要/ Abstract摘要:通过对成熟栎树树干上的肺叶地衣(Lobaria pulmonaria)和绿地衣(L. virens)的调查，揭示了二者生态偏好的差异。发现这些物种占据了显著不同的生态位，肺部乳杆菌发生在暴露较多的地点。不同物种的生态位宽度在暴露度方面相似，存在高度重叠，但在林分偏好方面差异不显著。两种植物的叶绿素含量和单位面积生物量相似，但它们表现出强烈的形态差异，这可能影响光捕获。以寄生菌丰度衡量的繁殖力在该地区较高，但在该地区肺芽孢杆菌可以无性繁殖和无性繁殖。本文还讨论了近年来褐藻丰度的下降以及鹿放牧对地衣区系的潜在影响。

NICHE SEPARATION AND OVERLAP IN THE FOLIOSE LICHENS LOBARIA PULMONARIA (L.) HOFFM. AND L. VIRENS (WITH.) LAUNDON IN THE KILLARNEY OAK WOODS, IRELAND

Abstract:An investigation of the lichens Lobaria pulmonaria and L. virens on the trunks of mature oak (Quercus spp) revealed differences in their ecological preferences. These species were found to occupy significantly different niches, with L. pulmonaria occurring in the more exposed sites. The niche widths were similar with respect to exposure and there was a high degree of overlap between the species, although they did not differ significantly in aspect preference. The chlorophyll content and biomass per unit area was similar for both species, but they showed strong morphological differences that could influence light capture. Fertility, measured as apothecium abundance, was greater in L. virens, but L. pulmonaria reproduced both asexually and asexually in this region. A recent decline in the abundance of Lobaria scrobiculata and the potential effects of deer grazing on the lichen flora are discussed.

期刊介绍： The journal aims to offer a broad coverage of the subject area, including the following: - biology and ecology of the Irish flora and fauna - microbial ecology - animal, plant and environmental physiology - global change - palaeoecology and palaeoclimatology - population biology; conservation of genetic resources - pollution and environmental quality; ecotoxicology - environmental management - hydrology - land use, agriculture, soils and environment. Submissions on other relevant topics are also welcome, and papers of a cross-disciplinary nature are particularly encouraged.
