The word 'paludarium' comes from the Latin word 'palus' meaning marsh or swamp and '-arium' which refers to an enclosed container. Paludaria can range in size from small, easily displayed boxes to biospheres large enough to contain entire trees. A prominent example of a very large paludarium is the tropical rainforest exhibit at the Montreal ...
The miniature size of Brachycephalus pulex is notable; one adult specimen had a snout–vent length of 6.45 millimetres (0.254 in). This makes B. pulex the smallest known vertebrate. Mature males exhibit an average length of 7.10 millimetres (0.280 in), while females are consistently slightly larger, with an average length of 8.15 millimetres ...
The length of birds' lower leg bones (an indicator of body size) shortened by an average of 2.4% and their wings lengthened by 1.3%. A similar study published in 2021 used measurements of 77 nonmigratory bird species captured live for banding in lowland Amazon rainforest .
While the animals in the Amazon are often larger than life, this South American rainforest region have some of the world’s smallest creatures This rainforest is full of tiny, miniature creatures ...
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.
For birds and flying mammals, geolocators often take the form of a little solar-powered harness, which is fitted to the back of the animal and can weigh as little as half a gram.
At small spatial scales (e.g. a dozen hectares or a local community) the body size-species richness pattern dissolves and the number of species per body size class is almost uniform (i.e. there is an equal number of small and large bodied species in the community (see fig. 2 b)).
Its tusks have been known to reach 2.7 m (9 ft) in length, although in modern populations they are most commonly recorded at a length of 0.6–0.9 m (2 ft 0 in – 2 ft 11 in). [1] The average walking speed of an elephant is 7.2 km/h (4.5 mph), but they can run at recorded speeds of up to 24 km/h (15 mph). [2]
