“…These climatic zones harbor distinct plant and animal species that have developed unique adaptations to their specific environments. The colder highlands experience a limited population due to temperature constraints, whereas the warmer lowlands reduce species diversity due to water scarcity [ 37 ]. Agriculture and animal farming are the primary sources of income for the people who live in the largest and most prone to drought areas.…”

“…In addition, the temperature decreases as the altitude rises, and evaporation decreases, resulting in higher Epr. Therefore, the precipitation increases with the increase in elevation [64,65]. When the altitude reaches 3500 m, the precipitation decreases as the altitude continues to rise because the altitude is too high.…”

To identify the vegetation dynamics and relationship with the hydrothermal conditions in the Yellow River basin (YRB), the spatial–temporal variations of EVI, effective precipitation (Epr), accumulated temperature (At), and their relationships were obtained based on the MODIS EVI data and meteorological data from the YRB during 2001–2020. The results indicate that EVI trends increased during 2001 to 2020, especially in the farmland, forestland, and grassland ecosystems. Epr and At have also increased over the last 20 years. Epr mostly increased faster in the grassland, and water bodies and wetland ecosystems. At mostly increased faster in the water bodies and wetland, desert, and forest ecosystems. Affected by Epr and At, the correlation between the EVI and hydrothermal conditions varied under different hydrothermal conditions. Compared to the At, the Epr was the restrictive factor for the EVI variations in the terrestrial ecosystem in the YRB. In addition, the dynamical thresholds of the EVI, Epr, and At were confirmed. This study can improve the understanding of vegetation variations and their response to regional climate change, which is critical for ecological conservation and the high-quality development of the YRB.

“…Humidity may have a mixed effect, with moderate levels being favourable for herbivore movement, while excessively high humidity could potentially limit their activity. Even a small climatic change can have a huge impact on the animal's survival, and our understanding of these patterns and environment‐dependent interactions will help to make better predictions and recommend possible conservation strategies and the co‐existence of herbivore populations is highly dependent on the environmental changes (Asfaw et al, 2019).…”

To the modern‐day conservationist, knowledge on giraffe (Giraffa camelopardalis) movement patterns is crucial for the effective management of this increasingly threatened species. The aim of this study was to determine the seasonal distances travelled by giraffes in a highly seasonal semi‐arid savanna area and to investigate how specific climatic factors influence their spatial distribution. Distributed over the 95,537‐ha reserve, we selected eight adult female giraffes that were equipped with radio transmitter collars using geographical positioning system devices to investigate their movement patterns over a 21‐month period in the Kalahari region of South Africa. Climatic data were collected using three weather stations at different locations in the study area. Giraffes moved significantly longer distances and for longer hours during the cool, dry season compared to other seasons. Both temperature and rainfall had statistically significant effects on distances travelled. The giraffes moved significantly longer distances with higher rainfall and temperature. They also moved significantly further during the middle of the day in all seasons, except winter. The reasons for these movement patterns are discussed with special emphasis on the influence of climatic factors on resource availability in a highly seasonal environment with periods of low resource availability.
