  1. 1. ENSO teleconnections - Analysis of time lag between tropical Pacific sea surface temperature and climate and vegetation anomalies

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jiri Navrátil; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; ENSO; teleconnections; climate; NDVI; Earth and Environmental Sciences;

    Abstract : El Niño-Southern Oscillation (ENSO) affects weather and climate in regions spread all around the Earth via teleconnections. While quite a lot of research has been done on recognizing what regions are affected by these and what is the sign of the associated temperature, rainfall and vegetation anomalies, not that much attention has been paid to the timing of the impacts with respect to the ENSO state.

  2. 2. An open source web GIS tool for analysis and visualization of elephant GPS telemetry data, alongside environmental and anthropogenic variables

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Patrick Kabatha; [2018]
    Keywords : geography; GIS; web GIS; web mapping; open source; wildlife; elephant; ecology; time series; GPS telemetry; Biology and Life Sciences; Earth and Environmental Sciences;

    Abstract : The movement and distribution of ecologically important herbivores such as elephants are of great significance to conservation biologist seeking to understand the fundamental triggers that influence their mobility and the extent to which these parameters affect how they utilize their immediate and surrounding resources. The recent advancement in animal tracking technology coupled with the availability of moderate to high-resolution satellite data, permits scientists to develop elephant cognitive maps of their adjacent environment, thus offering novel opportunities for research in the fields of wildlife movement ecology and the wider conservation biology.
