La lechuza de los arenales Athene cunicularia (Aves: Strigidae) se distribuye desde Canadá hasta Tierra del Fuego en América. Ocupa una gran variedad de hábitats naturales, ambientes urbano-rurales y agroecosistemas. En el Perú residen tres subespecies A. c. nanodes, (Berlepsch y Stolzmann, 1892), A…

气候是影响植物栖息地的重要因素之一,预测气候变化对植物潜在分布范围变动的影响,对促进植物资源的可持续利用具有重要意义。基于最大熵Maxent模型结合11个环境变量,预测2050s三种气候情景下(RCP2.6、RCP4.5和RCP8.5)南方红豆杉(Taxus chinensis var.mairei)在中国的潜在地理分布状况,分析影响其分布的主要因素,探讨其分布格局的改变对我国亚热带北界的指示意义。结果表明:(1)南方红豆杉的适宜栖息地(生境指数P>0.2)主要分布在我国亚热带暖温带季风区,绝大部分核心栖息地(生境指数P>0.6)分布在秦岭大巴山以南地区;(2)Jackknife测试结果显示,…

Aim: Forest composition and distribution are determined by a myriad of factors, including climate. As models of tropical rain forest, palms are often used as indicator taxa, particularly the Mauritiinae. We question, what characterizes the Mauritiinae pollen in the global fossil record? And when did…

A new species from central Amazonia, Chromolucuma brevipedicellata (Sapotaceae, Chrysophylloideae) is described and illustrated. It occurs in terra firme (non-flooded) forests near Manaus, Brazil. We compare C. brevipedicellata to similar species in terms of diagnostic morphology, as well as near-in…

Before evaluating the abundance and quality of nature in a city, one must define the concept of nature according to resident experience and climatological conditions. For Los Angeles (L.A.) County, home to a sociologically diverse and highly developed city in a Mediterranean climate that experienced…

Background Understanding the impacts of past and contemporary climate change on biodiversity is critical for effective conservation. Amphibians have weak dispersal abilities, putting them at risk of habitat fragmentation and loss. Both climate change and anthropogenic disturbances exacerbate these r…

Concern has been raised regarding red fox (Vulpes Vulpes) population increase and range expansion into alpine tundra, directly and indirectly enhanced by human activities, including carrion supply, and its negative impact on native fauna. In this study, we used cameras on bait stations and hunting r…

Some beetle species can attack honeybee colonies, causing severe damage to beekeeping. These pests include Oplostomus fuligineus, which is also known as the Large Hive Beetle (LHB). This beetle is native to Sub-Saharan Africa and has recently also been recorded in some parts of North Africa. It feed…

Clathrus archeri is a fungus native to Australia and New Zealand that has started to expand into Europe, and it is considered a potentially invasive species. In this study, we examine the historical occurrence, current geographical range and potential future changes in the distribution of C. archeri…

Phenakospermum guyannense is the only native species of Strelitziaceae in South America and occurs in the Amazon domain in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname and Venezuela. The species presents a negative sampling bias, probably due to the great effort necessar…
