Effects of amusing memes on concern for unappealing species

There is limited knowledge of the mechanisms that can inspire people's concern and engagement in the protection of unpopular and unappealing species. We analyzed Polish people's interest in themed internet memes featuring the proboscis monkey (Nasalis larvatus) and the consequences of this interest for conservation marketing. We examined Google Trends data, used Google Search, and searched popular media materials to estimate interest in the proboscis monkey in Poland. Photos of the proboscis monkey when presented with humor in internet memes attracted as much interest as usually more popular species (e.g., koala, panda, and orangutan) used in marketing by nongovernmental organizations. Amusing internet memes spread by social media positively correlated with increasing interest in the unappealing species, such as proboscis monkey. Interest in amusing internet memes positively correlated with individuals’ decisions to donate to 6 crowdfunding actions. Thus, conservation marketing that includes amusing memes and social media may provide a worthwhile complement to traditional campaigns and are likely to influence individuals who are unaffected by the usual means.     

利用Google Earth研究构造对喀斯特地貌的控制和对碳酸盐岩岩系风化成土的影响

通过互联网Google Earth欧洲卫星图像资料的观察,发现贵州喀斯特地区碳酸盐岩风化成土能力与地层岩性、构造和地貌等密切相关。二叠系生物礁石漠化显著,成土能力差;三叠系大冶组薄层灰岩成土能力高,很少有石漠化;地层倾角大的碳酸盐岩区,石漠化不显著;地层平缓的碳酸盐岩区,石漠化强或中等,碳酸盐岩风化成土能力中等。另外,大型节理带对碳酸盐岩风化成土具有明显的控制作用,节理带碳酸盐岩溶蚀相对强烈,常形成低洼地形,碳酸盐岩风化成土速率较高,红粘土堆积相对厚,不容易石漠化;而节理带间的区域往往地形较高,是石漠化易发育的区域。     

Considering connections between Hollywood and biodiversity conservation

Cinema offers a substantial opportunity to share messages with a wide audience. However, there is little research or evidence about the potential benefits and risks of cinema for conservation. Given their global reach, cinematic representations could be important in raising awareness of conservation issues and species of concern, as well as encouraging greater audience engagement due to their heightened emotional impact on viewers. Yet there are also risks associated with increased exposure, including heightened visitor pressure to environmentally sensitive areas or changes to consumer demand for endangered species. Conservationists can better understand and engage with the film industry by studying the impact of movies on audience awareness and behavior, identifying measurable impacts on conservation outcomes, and engaging directly with the movie industry, for example, in an advisory capacity. This improved understanding and engagement can harness the industry's potential to enhance the positive impacts of movies featuring species, sites, and issues of conservation concern and to mitigate any negative effects. A robust evidence base for evaluating and planning these engagements, and for informing related policy and management decisions, needs to be built.

Googling Trends in Conservation Biology

Web‐crawling approaches, that is, automated programs data mining the internet to obtain information about a particular process, have recently been proposed for monitoring early signs of ecosystem degradation or for establishing crop calendars. However, lack of a clear conceptual and methodological framework has prevented the development of such approaches within the field of conservation biology. Our objective was to illustrate how Google Trends, a freely accessible web‐crawling engine, can be used to track changes in timing of biological processes, spatial distribution of invasive species, and level of public awareness about key conservation issues. Google Trends returns the number of internet searches that were made for a keyword in a given region of the world over a defined period. Using data retrieved online for 13 countries, we exemplify how Google Trends can be used to study the timing of biological processes, such as the seasonal recurrence of pollen release or mosquito outbreaks across a latitudinal gradient. We mapped the spatial extent of results from Google Trends for 5 invasive species in the United States and found geographic patterns in invasions that are consistent with their coarse‐grained distribution at state levels. From 2004 through 2012, Google Trends showed that the level of public interest and awareness about conservation issues related to ecosystem services, biodiversity, and climate change increased, decreased, and followed both trends, respectively. Finally, to further the development of research approaches at the interface of conservation biology, collective knowledge, and environmental management, we developed an algorithm that allows the rapid retrieval of Google Trends data.     

Google Earth在海岸线修测调查中的应用研究

对Google Earth免费提供的高分辨率的卫星影像有效地用到海岸线修测调查中做了探讨.Google Earth提供的卫星图像匹配了视图的经纬度等位置信息,并可以放入点、线和面等标记,基于其高清遥感地图的岸线位置与走向能直接反映海岸线最新变化情况.通过对上海市海岸线修测数据在GE平台上进行验证,双向分析修测点位精度和GE精度,提出数据判读、岸线自动提取等功能应用.

2000年来中国生态状况时空变化格局

21世纪以来,我国在经济快速发展的同时高度重视生态环境保护,一系列生态修复工程和空间管控措施使生态状况发生了巨大变化;然而目前对于全国生态状况宏观格局的认识仍十分有限。借助 Google Earth Engine（GEE）遥感云计算平台,采用主成分分析方法和MODIS数据构建的绿度NDVI、热度LST、湿度WET和干度NDSI四个指标,生成长时间序列的遥感生态指数RSEI数据集,完整刻画了中国2000年来生态状况的时空连续变化格局。研究发现:在空间格局上,东南沿海地区生态状况优于西北地区;变化趋势上,全国生态状况除上海、西藏和澳门之外均显著改善,RSEI增长最多的三个省份为山西、陕西和河北。进一步采用遥感云计算定量评价了2000年来生态状况变化的宏观格局,以期为国土空间管控和生态保护提供科学支持。     

基于Google Earth Engine分析黄土高原植被覆盖变化及原因

为探明黄土高原植被覆盖时空变化及其原因,基于Google Earth Engine（GEE）,采用Landsat Surface Reflectance data（陆地卫星地表反射率数据）分析了黄土高原1987~2015年间植被覆盖度的时空变化规律,并借助累积量斜率变化率方法对引起植被覆盖度变化的气候和人为因素进行了量化分析.结果表明：黄土高原年均植被覆盖度由1987年的41.78%增加到2015年的53.23%,增速为0.38%/a（P<0.05）.其中,1987~1999年年均植被覆盖度变化趋势不显著（P>0.05）;而退耕还林还草工程实施以来（2000~2015年）,年均植被覆盖度显著增加（P<0.05）,增速达到0.59%/a.由像元尺度分析,黄土高原72.93%的区域植被覆盖度呈增加趋势,其中38.31%的区域增加趋势显著（P<0.05）.植被覆盖度的变化受气候和人为因素的共同影响,以1987~1999年为基准期,气候变化和人类活动对黄土高原2000~2015年间植被覆盖度变化的相对贡献率分别为23.77%、76.23%,人类活动为引起黄土高原植被覆盖度变化的主要原因.退耕还林还草工程极大地改善了黄土高原的植被覆盖状况,但是城市的扩张使得部分地区的植被覆盖呈显著退化现象.     

鄱阳湖流域生态环境动态评估及驱动因子分析

鄱阳湖流域生态环境是我国南方地区生态文明建设的重要组成部分.基于Landsat卫星遥感影像,利用主成分分析方法构建遥感生态指数(RSEI)作为生态环境质量评价指标,引入地理探测器模型定量剖析不同影响因素对生态环境空间分异性的影响,分析鄱阳湖流域1990～2020年生态环境质量变化及不同驱动因子的影响程度.结果表明：(1)流域内生态环境质量存在明显的区域性差异,生态质量等级为差和较差地区主要分布在流域中北部的低海拔平原与台地,质量等级为优和良地区主要分布在流域西南部的丘陵山地区域;(2)近30年鄱阳湖流域生态环境整体呈改善趋势,改善地区主要位于低海拔平原区域;(3)人口密度是鄱阳湖流域生态环境质量变化中驱动力最大的影响因子,与城市化发展密切相关的夜间灯光指数因子q值多年来呈升高趋势,鄱阳湖流域生态环境质量受城市化发展的影响越来越大.结果可为鄱阳湖流域生态环境保护工作提供理论依据.
