Question
Given that R-(KXm)/ t, and given the constants below, calculate R for each species and for each resource and answer the following questions Species 1Species 2 R* Resource 1 K-10 g/mlK-7g/ml m - 12 per day m per day -6 per dayI per day Resource 2K-7gml m- 5 per day m-6per day T- 10 per day 20 per What do you predict will happen after competition for resource 1 (only resource l in short supply)? What would happen if both resources were simultaneously in short supply? What is character displaccment? Draw an example of character displacement in plant height when two species (you can name them yourself) are sympatrie and allopatric. What is Hutchinson's Ratio? Explain the Hutchinson ratio found in the three species of cat: Felis sylvestris, F. chaus, and F. caracal. Drawing a picture may help you remember the ratio.Explanation / Answer
DEFINITION OF HUTCHINSON’s RATIO
It is the ratio of the size differences between same species when they were living together as compared to when they were isolated. It was named after G. Evelyn Hutchinson who concluded that various key attributes in species varied according to their ratio of 1:1.1 to 1:1.
WILDCAT( felis silvestris)
The wildcat is a species complex of small cats, comprising the European wildcat.
The former is native to Europe and the Caucasus. The latter – the ancestor of the domestic cat (F. catus) – ranges through much of Africa; Southwest and Central Asia into India; and western China.
Because of the species' wide range the wildcat is listed as Least Concern on the IUCN Red List since 2002. Crossbreed of wildcats and domestic cat (Felis catus) occurs in particular in Europe and is considered a potential threat for the preservation of the wild species.
The wildcat shows a high degree of geographic variation. Whereas the Asiatic wildcat is spotted, the African wildcat is faintly striped, has short sandy-gray fur, banded legs. The European wildcat is striped, has long fur and a bushy tail with a rounded tip, and is larger than a domestic cat.
The African wildcat is the ancestor of the domestic cat. Genetic, morphological and archaeological evidence suggests that domestication of Old-World wildcats began approximately 7500 years BCE in the Fertile Crescent region of the Near East.
Theirassociation of wildcats with humans appears to have developed along with the growth of agricultural villages during the Neolithic Revolution. Results of a phylogeographic analysis suggest to include the Chinese mountain cat as a Felis silvestris subspecies.
F. Caracal cat
The caracal (Caracal caracal) is a medium-sized wild cat native to Africa, the Middle East, Central Asia, and India. It is characterised by a robust build, long legs, a short face, long tufted ears, and long canine teeth. Its coat is uniformly reddish tan or sandy.
It reaches 40–50 cm (16–20 in) at the shoulder and weighs 8–18 kg (18–40 lb). It was first scientifically described by German naturalist Johann Christian Daniel von Schreber in 1776.
Three subspecies are recognised since 2017.
The caracal is a carnivore that typically preys upon small mammals and birds.
It can leap higher than 3 m (9.3ft) and catch birds in midair. It stalks its prey until it is within 5.3 m (14ft) of it, after which it runs it down, the prey being killed by a bite to the throat or to the back of the neck.
Breeding takes place throughout the year, with both sexes becoming sexually mature by the time they are a year old.
Gestation lasts between two and three months which results in a litter of one to six kittens. Juveniles leave their mothers at nine to ten months, though their few females stay back with their mothers. The average lifespan of the caracal cat is nearly 16 years.
F. Chaus (jungle cat)
The jungle cat (F. chaus), a medium-sized cat native to the Middle East, South and Southeast Asia and southern China. It inhabits foremost wetlands like swamps, littoral and riparian areas with dense vegetation.
The jungle cat has a uniformly sandy, reddish-brown or grey fur without spots; melanistic and albino individuals are also known. It is solitary in nature, except during the mating season and mother-kitten families. Adults maintain territories by urine spraying and scent marking.
