Steppes and xerothermic grasslands are hotspots of biodiversity, but are threatened by habitat destruction and fragmentation. The heath bush-cricket, Gampsocleis glabra, is considered to be a specialist of xerothermic habitats and appears in national red lists as a threatened species in several European countries. The goal of the current research was to determine the habitat requirements of G. glabra in an isolated habitat patch in Poland, at the northern edge of its range. By comparing the composition of plant species and vegetation architecture of vacant and occupied sites in the summers of 2018 and 2019, it was found that this population of G. glabra still maintained a strict specialisation for the xerothermofilous Festuco-Brometea plant community. On the contrary to previous studies, however, Stipa-type grasses were not essential for the occurrence of the species and the majority of occupied areas were based on the plant Brachypodium pinnatum. The physiognomy of plant communities was crucial for the abundance of stridulating males, which showed a preference for dense grasses at 10 cm high. The habitat characteristics of patches occupied by males and females did not differ significantly. The study of habitat requirements of this endangered Orthoptera species in an isolated habitat patch could serve as a prelude to the restoration of similar locations before it becomes extinct. This study may also underpin the development of a global conservation strategy for G. glabra.

濒危荒地丛林蟋蟀Gampsocleis glabra（直翅目，Tettigoniidae）在孤立种群中的栖息地要求

草原和干热草原是生物多样性的热点，但受到栖息地破坏和破碎化的威胁。荒地丛林蟋蟀 Gampsocleis glabra 被认为是干热栖息地的专家，并在几个欧洲国家作为受威胁物种出现在国家红色名录中。当前研究的目标是确定 G. glabra 在其分布范围北部边缘的一个孤立栖息地斑块中的 G. glabra 的栖息地需求。通过比较 2018 年和 2019 年夏季空地和已用地的植物物种组成和植被结构，发现该 G. glabra 种群仍然对干热丝状 Festuco-Brometea 植物群落保持严格的专业化。然而，与以往的研究相反，针茅型草对于该物种的出现来说不是必需的，并且大部分被占领的区域都是基于植物 Brachypodium pinnatum。植物群落的地貌对于雄性雄性的丰度至关重要，雄性表现出对 10 厘米高的茂密草的偏好。雄性和雌性占据的斑块的栖息地特征没有显着差异。在孤立的栖息地中研究这种濒临灭绝的直翅目物种的栖息地需求，可以作为在其灭绝之前恢复类似地点的前奏。这项研究也可能支持为 G. glabra 制定全球保护战略。植物群落的地貌对于雄性雄性的丰度至关重要，雄性表现出对 10 厘米高的茂密草的偏好。雄性和雌性占据的斑块的栖息地特征没有显着差异。在孤立的栖息地中研究这种濒临灭绝的直翅目物种的栖息地需求，可以作为在其灭绝之前恢复类似地点的前奏。这项研究也可能支持为 G. glabra 制定全球保护战略。植物群落的地貌对于雄性雄性的丰度至关重要，雄性表现出对 10 厘米高的茂密草的偏好。雄性和雌性占据的斑块的栖息地特征没有显着差异。在孤立的栖息地中研究这种濒临灭绝的直翅目物种的栖息地需求，可以作为在其灭绝之前恢复类似地点的前奏。这项研究也可能支持为 G. glabra 制定全球保护战略。在孤立的栖息地中研究这种濒临灭绝的直翅目物种的栖息地需求，可以作为在其灭绝之前恢复类似地点的前奏。这项研究也可能支持为 G. glabra 制定全球保护战略。在孤立的栖息地中研究这种濒临灭绝的直翅目物种的栖息地需求，可以作为在其灭绝之前恢复类似地点的前奏。这项研究也可能支持为 G. glabra 制定全球保护战略。
