“…This study on vegetation NDVI change and its relationship with climate change and human activities includes 3 aspects. The first is to analyze different spatial and temporal vegetation cover change in global and regional scale based on GIMMS NDVI, SPOT VGT NDVI, MODIS NDVI and Landsat NDVI data [8]- [11]. The second is to analyze the effect of climate change on vegetation based on the correlation coefficient and linear change trend method [12]- [14].…”

Yulin is a typical ecological fragile area in China, and its vegetation ecosystem is so fragile that could be vulnerable to climate change and human activities. Spatial and temporal change of vegetation Normalized Difference Vegetation Index (NDVI) and its relationship with climate change and human activities were analyzed based on MODIS NDVI data from 2000 to 2015, as well as annual temperature and precipitation data from 2000 to 2014, and linear trend analysis, correlation and buffer analysis were used. Result showed: 1) NDVI value was small and vegetation cover was low, but NDVI had a linear growth rate of 0.0096/annum from 2000 to 2015 in Yulin area. The area of growth trend accounted for 97.06% of the total area, while the area with decreased rate was small, which mainly had correlation with human activities, and was distributed in the southwest mountain area, urban neighborhood, and river valley in the middle and east of Yulin area. 2) Correlation analysis between NDVI and temperature, precipitation, respectively, reflected that negative correlation was between NDVI and temperature, while positive correlation was between NDVI and precipitation. Furthermore, the role of precipitation was higher than that of temperature in the process of interaction between NDVI and temperature, precipitation. 3) NDVI change process in the range of human activities indicated that the intensity of human activities in buffer_city area was higher than that in buffer_county area. Buffer_city area was divided into within 5 km area with dramatic impact by human activities, and from 5 km to 9 km area with less impact by human activities, and outside 9 km area with mini-affected by human activities.

“…(Schwartz and Henderson 1991;Stuart et al 2008;Sangermano et al 2015a). Once considered Endangered (EN) by the IUCN (Hedges et al 2004), the species was reevaluated during the Caribbean Amphibian Ark Conservation Needs Assessment and, based on new locality records and studies of habitat use (Foden et al 2013;Sangermano et al 2015a), an estimated occupation area of between 1,351 and 2,000 km², a severely fragmented population, and a continuous decrease in its area of occurrence and habitat quality (Stuart et al 2008;Henderson and Powell 2009;Powell and Incháustegui 2009;Sangermano et al 2015aSangermano et al , 2015b, its threat status was reduced to Vulnerable (VU) (IUCN SSC Amphibian Specialist Group 2013b).…”

An integrative study of species distribution modelling and conservation genetics: Magnolia in Hispaniola

et al. 2023

View full text Add to dashboard Cite

On the island of Hispaniola, five endemic species of Magnolia occur, all of which are threatened with extinction. Little is known about their distribution and genetic health, hampering targeted conservation actions. The objective of this study is to assess the potential distribution and the genetic health of the Magnolias of Hispaniola, to inform concrete guidelines for effective conservation management. Using species distribution modelling (SDM), we predict habitat suitability for the Magnolias of Hispaniola by analysing 21 variables, describing climate and landscape features, on 635 occurrences. We genotyped 417 individuals using 16 microsatellite markers, to test for genetic structure and degree of inbreeding. The SDM and genetic data confirm the recognition of the four studied Magnolia species. The known individuals of the three Dominican Magnolias are structured into five populations which show ample genetic diversity and little inbreeding overall. For conservation management, we propose to focus on exploration using the SDM results, and protection and reinforcement using the genetic and occurrence data. The genetic results guide prioritization of species and populations. The SDM results guide spatial prioritization. Installing and/or protecting habitat corridors between populations, starting with the two species with the lowest genetic diversity and relatively nearby populations, is recommended as a durable conservation strategy. Meanwhile, reinforcement efforts can be undertaken to artificially increase gene flow for which we appoint sink and source population pairs, using the genetic data.
