Bergmann's rule - Penguins on the Earth (mass m, height h) [1] Bergmann's rule is an ecogeographical rule that states that, within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer regions.
Badulla" Badulla was an isolated village until the British built roads from Kandy and Nuwara Eliya in the mid 19th century, as part of the growing plantation economy. By the 20th century Badulla had become a regional hub, with the British establishing it as the capital of Uva Wellassa, now known as the Uva Province.
Allen's rule - Hare and its ears on the Earth [1]. Allen's rule is an ecogeographical rule formulated by Joel Asaph Allen in 1877, [2] [3] broadly stating that animals adapted to cold climates have shorter and thicker limbs and bodily appendages than animals adapted to warm climates.
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
Haputale (Sinhala: හපුතලේ; Tamil: ஹபுதலே) is a town of Badulla District in the Uva Province, Sri Lanka, governed by an Urban Council. [1] The elevation is 1431 m (4695 ft) above the sea level. The area has a rich bio-diversity dense with numerous varieties of flora and fauna.
A more technical definition was provided by Grady et al, [7] who argued for dinosaur mesothermy on the basis of their intermediate growth rates, and the empirical relationship between growth, metabolism and thermoregulation in extant vertebrates.
With elevated regions most intensely feeling the effects of climate change and these effects being linked to increased species diversity in impacted regions, this is a key consideration in prioritizing habitats for conservation efforts. [3] At an ecotone, species abundances change relatively quickly compared to the environmental gradient.
As instrumental records only span a tiny part of Earth's history, the reconstruction of ancient climate is important to understand natural variation and the evolution of the current climate. Paleoclimatology uses a variety of proxy methods from Earth and life sciences to obtain data previously preserved within rocks , sediments , boreholes ...
