Our research demonstrates that in mirroring prevailing human biases towards different insect groups, LLM chatbots oversimplify insect diversity by predominantly restricting “bees” to honeybees and “wasps” to yellowjackets, neglecting the majority of biodiversity that includes wild bees and parasitoid wasps, while also favouring Nearctic species in ...

Coastal reclamation impacts on carbon storage in China’s coastal wetland [PDF]
滨海湿地具有较高的初级生产力和较缓慢的有机质降解速率,是缓解全球变暖的有效碳汇,得到全球学术界的广泛关注。近年来由于人口增长和沿海城市的快速发展,海岸带地区围填海活动呈加剧趋势,导致滨海湿地的急剧退化。开展围填海活动对滨海湿地碳储量造成影响的研究,对我国海岸带围填海活动的优化管理、制定滨海湿地保护行动计划以及减缓气候变化的战略决策具有非常重要的学术价值和现实意义。 本论文以全国围填海区内的滨海湿地作为研究对象,基于全国围填海土地利用分类数据、滨海湿地和沿海自然保护区空间分布数据以及文献检索碳密度数据 ...

Effectiveness of protected areas in the Caucasus Mountains in preventing rangeland degradation
Abstract As land use intensifies globally, it increasingly exerts pressure on protected areas. Despite open, nonforested landscapes comprising up to 40% of protected areas globally, assessments have predominately focused on forests, overlooking the major pressures on rangelands from livestock overgrazing and land conversion.

从植物区系、生物多样性容量、通量和质量等方面比较了武夷山脉从南到北梁野山、闽江源、武夷山3个国家级自然保护区中蕨类植物的生物多样性.结果表明,在武夷山脉由南到北,蕨类植物的热带性成分趋于递减,北温带分布及其变型、东亚分布及其变型递增.由物种数及丰富度指数DGl可以得出,武夷山自然保护区蕨类植物生物多样性容量最大.连通性方面,武夷山脉不同的保护区间物种水平的相似性不到55%,而从武夷山脉南段至中段、中段至北段,种的β多样性指数βL值都达到30%,这两点说明武夷山脉是蕨类植物的现代分化中心之一 ...
