Abstract This commentary discusses new advances in the predictability of east African rains and highlights the potential for improved early warning systems (EWS), humanitarian relief efforts, and agricultural decision‐making. Following an unprecedented sequence of five droughts, 23 million east Africans faced starvation in 2022, requiring >$2 billi...

气候变暖可能严重影响卵生物种的胚胎发育和幼体生长。由于产卵事件先后发生在整个繁殖季节, 评估气候变暖对卵生物种繁殖的总体影响十分困难。一次成功的产卵除了让胚胎能够完成发育外, 还需要让卵在有利于后代生存和能量积累的时机孵化。我们提出了一个新的指标--产卵机会(EO) --用来估计一年中一窝新产卵能够产生成功越冬后代的时间。结合微气候数据、胚胎发育数据和生物物理模型, 我们估算了模式物种东部强棱蜥(Sceloporus undulatus)在当前气候条件和气候变暖情景下, 其分布范围内的EO。我们预测, 在东部强棱蜥分布区内的11407个位点中, 74.8%的位点的EO将随着气候变暖而缩短。由孵化成功率降低和后代能量积累减少所造成的EO损失(72.6%和72.9%)大于由新生幼体热压力所造成的...

In action-adventure video games, it is usual that the climate and, particularly, the atmospheric space weather, are used as a tool to enhance the gameplay and the aes-thetic approach of the game. However, in certain platforms, they have also been used as dramatic agents capable not only of favoring certain plastic or narrative constructions, but al...

Rural housing in the Andes of Peru is precarious and does not protect communities from the ravages of cold temperatures. This problem has justified the development of projects to improve thermal behavior; however, they have not been developed massively due to their high cost and technical requirement. This article analyzes the thermal behavior of t...

The La Bramadora wetland basin, located in the municipality of Sopetrán, Antioquia, Colombia, is subject to a torrential regime manifested through the formation of colluvium that accumulates in the lower parts of the slopes and the dragging of fine materials that go to the riverbeds and slowly to the wetland until it constitutes a 950-meter sequenc...

El clima se ha propuesto como uno de los posibles factores desencadenantes de la extinción de los Neandertales. Las oscilaciones rápidas y abruptas, registradas en diferentes registros climáticos del hemisferio norte, empujaron los ecosistemas hacia resultados catastróficos durante el Estadio Isotópico 3 (MIS3). En estas condiciones, la supervivenc...

Agrometeorological data is important in agricultural research, especially in agronomy and crop science, for investigating genotype by environment interactions. The AgERA5 dataset from the Copernicus Climate Data Store provides free and public access to global gridded daily agrometeorological data, from 1979 to present, with ready to use variables t...

两栖动物是陆生脊椎中最受胁的类群, 中国两栖动物的受胁状态更为严峻。人类活动导致的环境变化深刻影响着物种的分布和种群动态。传统生态学认为大尺度上的物种分布格局主要受当前气候和物种扩散能力的影响。近几百年来, 人类活动的日益加剧, 其对物种分布的影响也日益加强。中国幅员辽阔, 自然环境类型多样, 同时人口众多。然而, 目前尚不知自然因素和人类活动是如何影响着中国两栖动物当前的分布格局?人类活动的影响是否已经超出了气候等自然环境因素的影响?我们通过三种方法收集了中国两栖动物的分布数据, 包括615篇文献, 网上公开数据和野外调查数据, 最终获得中国196种两栖动物的25826个分布点。并将这些数据用于预测两栖动物当前潜在分布区, 用实际分布点代表其当前实际分布区, 实际分布区和潜在分布区的比值来...
