Solving the “species bias” to facilitate orchid multi-scenario conservation planning in the south of the Hengduan Mountains
TLDR
Wang et al. as mentioned in this paper identified the critical areas of suitability, diversity, and protection of orchids in this region, providing a meaningful reference for regional biodiversity conservation planning and producing a migrated method for biogeographic analysis in global biodiversity hotspots not just orchid species.Abstract:
Abstract detailed analyses of specific taxonomic groups at finer geographic scales to identify and prioritize biodiversity hotspots is a prominent method for optimizing conservation efforts, especially for the uneven species richness. The ecological suitability prediction and analysis of representative species provide vital references for conservation planning. Yet, in predicting suitability for multi-species or groups by species distribution models (SDMs) under a highly heterogeneous environment, species bias may occur cause of the unequal protection status and the spatial autocorrelation processing of occurrence data. For this, diversity, and protection hotspots were mapped in the south of the Hengduan Mountains, a significant site for global biodiversity. Specifically, creating a network of 1 km 2 grid cells spanning the region, counting the orchid species, quantifying the protection value, and classifying attributes by the Jenks. And 5 km and 10 m buffer zone for each grid containing attributes compose the diversity and protection hotspot layers and were compared with the orchid suitability map modeled by SDMs. Results showed that even though there were extensively suitable habitats for orchids, the model results cannot completely cover whole the diversity and protection hotspots at any scale. Based on the map attributes, multi-scenario conservation planning was proposed. This study identifies the critical areas of suitability, diversity, and protection of orchids in this region, providing a meaningful reference for regional biodiversity conservation planning and producing a migrated method for biogeographic analysis in global biodiversity hotspots not just orchids. Besides, the results will supply crucial regional information for global biodiversity conservation. read more

WorldClim 2: new 1-km spatial resolution climate surfaces for global land areas
TL;DR: In this paper, the authors created a new dataset of spatially interpolated monthly climate data for global land areas at a very high spatial resolution (approximately 1 km2), including monthly temperature (minimum, maximum and average), precipitation, solar radiation, vapour pressure and wind speed, aggregated across a target temporal range of 1970-2000, using data from between 9000 and 60,000 weather stations.

Comparison of quantum and semiclassical radiation theories with application to the beam maser

TL;DR: In this article, it was shown that the semiclassical theory, when extended to take into account both the effect of the field on the molecules and the effects of the molecules on the field, reproduces the same laws of energy exchange and coherence properties as the quantized field theory, even in the limit of one or a few quanta in the field mode.

The use of ‘altitude’ in ecological research
TL;DR: There are two categories of environmental changes with altitude: those physically tied to meters above sea level, such as atmospheric pressure, temperature and clear-sky turbidity; and those that are not generally altitude specific, suchAs moisture, hours of sunshine, wind, season length, geology and even human land use.

TL;DR: It is hoped this synthesis improves understanding of these prioritization approaches and that it results in more efficient allocation of geographically flexible conservation funding.
