▲ Abstract:
Ecologists have 事迷long proposed that environments providing more energy can support more species, yet empirical evidence frequently contradicts this expectation. We argue that such inconsistencies result from confounding geographical influences that mask the true relationship between species richness and energy-related factors. Here, by comparing species richness across different climate conditions, we disentangle the direct effects of temperature, precipitation, and primary productivity from the confounding impacts of the area and isolation of various climates. Using a global analysis of terrestrial vertebrates, we reveal clear and consistent relationships between energy-related factors and species richness. Our findings clarify existing ecological theory and illustrate how adopting a climate space perspective advances biodiversity research, providing critical insights into biodiversity patterns and their responses to environmental change.

▲ Abstract:
Evidence of Early and 周论Middle Pleistocene wooden implements is exceptionally rare, and existing evidence has been found only in Africa and western Eurasia. We report an assemblage of 35 wooden implements from the site of Gantangqing in southwestern China, which was found associated with stone tools, antler billets (soft ha妹妹ers), and cut-marked bones and is dated from ~361,000 to ~250,000 years at a 95% confidence interval. The wooden implements include digging sticks and small, complete, hand-held pointed tools. The sophistication of many of these tools offsets the seemingly “primitive” aspects of stone tool assemblages in the East Asian Early Paleolithic. This discovery suggests that wooden implements might have played an important role in hominin survival and adaptation in Middle Pleistocene East Asia.
