The Hyrcanian forests are thought to have served as a refugium for certain species during changing climatic conditions. The Iranian edible dormouse ( Glis persicus ) is an endemic of this ecoregion, and is thought to have evolved when mid- Miocene climatic change led to the fragmentation of the ancestral Glis population, with one such ...
The extensive reed beds of tiger habitat were increasingly converted to cropland for planting cotton and other crops that grew well in the rich silt along rivers. [27] The tiger was already vulnerable due to the restricted nature of its distribution, having been confined to watercourses within the large expanses of desert environment. [25]
Hyrcania (/ h ər ˈ k eɪ n i ə /; Greek: Ὑρκανία Hyrkanía, [1] Old Persian: 𐎺𐎼𐎣𐎠𐎴 Varkâna, [2] Middle Persian: 𐭢𐭥𐭫𐭢𐭠𐭭 Gurgān, Akkadian: Urqananu) [2] is a historical region composed of the land south-east of the Caspian Sea in modern-day Iran and Turkmenistan, bound in the south by the Alborz mountain range and the Kopet Dag in the east.
Estimated to have been around 4 years old, the adult male had been hit by a car, officials said. A month earlier, the body of another adult tiger was found by an expressway in Pahang state.
The Caucasus-Anatolian-Hyrcanian temperate forests is a composite ecoregion of southern Europe and West Asia, designated by the World Wildlife Fund as one of their Global 200 ecoregions, a list of priority ecoregions for conservation.
Data from the International Tiger Studbook 1938–2018 indicate that captive tigers lived up to 19 years. [158] The father does not play a role in raising the young, but he encounters and interacts with them. The resident male appears to visit the female–cub families within his home range. They socialise and even share kills.
The Caspian Hyrcanian mixed forests along the Alborz Mountains are one of the most important habitats for the leopard in the country. Most leopards were recorded in habitats with temperatures of 13 to 18 °C (55 to 64 °F), maximum 20 days of ice cover per year and an annual rainfall of more than 200 mm (7.9 in). [ 48 ]
The leaves provide energy and nutrients for the trees, which provide homes and food for the forest. Through satellite data, the radiation use efficiency (RUE) calculates the annual amount of photosynthesis that occurs in temperate rainforests. A diverse amount of photosynthesis occurs based on the location and microclimates of the forest.
