The village is located at a distance of 21 kilometres from the district headquarters Bandipore . The village is situated on the banks of the famous and largest freshwater lake of India, the Wular Lake . Its circumference is partly bound by huge mountains and dense green forests. The
44-695: A literacy rate of 57.82%. At the time of the 2011 census, 82.39% of the population spoke Kashmiri , 8,82% Gojri , 4.18% Shina , 1.91% Pahari and 1.27% Hindi as their first language. Sex ratio A sex ratio is the ratio of males to females in a population . As explained by Fisher's principle , for evolutionary reasons this is typically about 1:1 in species which reproduce sexually . However, many species deviate from an even sex ratio, either periodically or permanently. Examples include parthenogenic and androgenetic species, periodically mating organisms such as aphids, some eusocial wasps , bees , ants , and termites . The human sex ratio

Bandipora district Bandipore district (also spelt as Bandipora or Bandipur ) is an administrative district of Indian -administered Jammu and Kashmir in the disputed Kashmir region. It is one of the 20 districts in the Jammu and Kashmir. Bandipore town is the administrative headquarters of the district. Bandipore is located in
88-479: A few plover species is clearly related to a strongly male-biased adult sex ratio. Those species with male care and polyandry invariably have adult sex ratios with a large surplus of males, which in some cases can reach as high as six males per female. Male-biased adult sex ratios have also been shown to correlate with cooperative breeding in mammals such as alpine marmots and wild canids . This correlation may also apply to cooperatively breeding birds, though
110-635: A population of 392,232 as per 2011 census. Some of the institutions and colleges of Bandipur which provide quality education to the students of district Bandipore. The district comprises seven tehsils: Ajas, Aloosa, Bandipore, Sumbal, Hajin, Gurez and Tulail. The district has three Vidhan Sabha constituencies: Gurez , Bandipore and Sonawari . All of these are part of Baramulla Lok Sabha constituency . The district comprises twelve community development blocks: Aloosa, Arin, Baktoor, Bandipore, Bonkoot, Ganastan, Gurez, Hajin, Naidkhai, Nowgam, Sumbal and Tulail. Languages of Bandipore district (2011) According to
132-411: Is a field of academic study which seeks to understand the sex ratios observed in nature from an evolutionary perspective. It continues to be heavily influenced by the work of Eric Charnov . He defines five major questions, both for his book and the field in general (slightly abbreviated here): Biological research mostly concerns itself with sex allocation rather than sex ratio, sex allocation denoting

Bandipore district is the only district in Kashmir Division that shares border with Pakistan-administered Gilgit-Baltistan region. This district occupies an area of 398 km . The district has
176-460: Is of particular interest to anthropologists and demographers. In human societies, sex ratios at birth may be considerably skewed by factors such as the age of mother at birth and by sex-selective abortion and infanticide . Exposure to pesticides and other environmental contaminants may be a significant contributing factor as well. As of 2024, the global sex ratio at birth is estimated at 107 boys to 100 girls (1,000 boys per 934 girls). By old age,
198-497: Is one of the wildlife area and only one wildlife range in Bandipora. There are hundreds of Wild Animals like, Leopard, Black Bear, Mask Dear and many other Wild Animals. A large stream flows through the village and is called the "BudKul". According to the 2011 census of India , Ajas has 1908 households. The literacy rate of Ajas village was 56.88% compared to 67.16% of Jammu and Kashmir. In Ajas, Male literacy stands at 68.91% while
220-504: The 2011 census Bandipore district has a population of 392,232, roughly equal to the nation of Maldives . This gives it a ranking of 561st in India (out of a total of 640 ). The district has a population density of 1,117 inhabitants per square kilometre (2,890/sq mi) . Its population growth rate over the decade 2001–2011 was 26.31%. Bandipore has a sex ratio of 899 females for every 1000 males (this varies with religion), and
242-546: The 1:1 ratio is the evolutionarily stable strategy (ESS). This ratio has been observed in many species, including the bee Macrotera portalis . A study performed by Danforth observed no significant difference in the number of males and females from the 1:1 sex ratio. Spending equal amounts of resources to produce offspring of either sex is an evolutionarily stable strategy : if the general population deviates from this equilibrium by favoring one sex, one can obtain higher reproductive success with less effort by producing more of
SECTION 10
#1732783333010264-429: The allocation of energy to either sex. Common research themes are the effects of local mate and resource competition (often abbreviated LMC and LRC, respectively). Fisher's principle (1930) explains why in most species, the sex ratio is approximately 1:1. His argument was summarised by W. D. Hamilton (1967) as follows, assuming that parents invest the same whether raising male or female offspring: In modern language,
286-549: The evidence is less clear. It is known, however, that both male-biased adult sex ratios and cooperative breeding tend to evolve where caring for offspring is extremely difficult due to low secondary productivity, as in Australia and Southern Africa . It is also known that in cooperative breeders where both sexes are philopatric like the varied sittella , adult sex ratios are equally or more male-biased than in those cooperative species, such as fairy-wrens , treecreepers and
308-477: The female literacy rate was 44.24%. Ajas is connected by road with other places in Jammu and Kashmir and India by the Bandipora-Srinagar Road, Ganderbal-Mansbal Road, etc. The nearest railway stations to Ajas are Sopore railway station and Baramulla railway station , located at a distance of 29 and 38 kilometres from Ajas. The nearest airport is Srinagar International Airport located at

The district is known for its tourist places such as Wular Vintage Park, Athwatoo and Gurez valley. Before 1947, this town was a big trade and literary centre of Kashmir. This district was carved out from the erstwhile Baramulla district in 2007. The district
352-413: The male fish dies, the strongest female changes its sex to become the male for the group. All of these wrasses are born female, and only become male in this situation. Other species, like clownfish, do this in reverse, where all start out as non-reproductive males, and the largest male becomes a female, with the second-largest male maturing to become reproductive. Traditionally, farmers have discovered that
374-434: The most economically efficient community of animals will have a large number of females and a very small number of males. A herd of cows with a few bulls or a flock of hens with one rooster are the most economical sex ratios for domesticated livestock. It was found that the amount of fertilizing pollen can influence secondary sex ratio in dioecious plants. Increase in pollen amount leads to decrease in number of male plants in
396-829: The other. For species where the cost of successfully raising one offspring is roughly the same regardless of its sex, this translates to an approximately equal sex ratio. Bacteria of the genus Wolbachia cause skewed sex ratios in some arthropod species as they kill males. Sex-ratio of adult populations of pelagic copepods is usually skewed towards dominance of females. However, there are differences in adult sex ratios between families: in families in which females require multiple matings to keep producing eggs, sex ratios are less biased (close to 1); in families in which females can produce eggs continuously after only one mating, sex ratios are strongly skewed towards females. Several species of reptiles have temperature-dependent sex determination , where incubation temperature of eggs determines
418-440: The progeny. This relationship was confirmed on four plant species from three families – Rumex acetosa ( Polygonaceae ), Melandrium album (Caryophyllaceae), Cannabis sativa and Humulus japonicus ( Cannabinaceae ). In charadriiform birds, recent research has shown clearly that polyandry and sex-role reversal (where males care and females compete for mates) as found in phalaropes , jacanas , painted snipe and
440-485: The sex of the individual. In the American alligator , for example, females are hatched from eggs incubated between 27.7 to 30 °C (81.9 to 86.0 °F), whereas males are hatched from eggs 32.2 to 33.8 °C (90.0 to 92.8 °F). In this method, however, all eggs in a clutch (20–50) will be of the same sex. In fact, the natural sex ratio of this species is five females to one male. In birds, mothers can influence
462-414: The sex of their chicks. In peafowl , maternal body condition can influence the proportion of daughters in the range from 25% to 87%. Dichogamy (sequential hermaphroditism) is normal in several groups of fish, such as wrasses , parrotfish and clownfish . This can cause a discrepancy in the sex ratios as well. In the bluestreak cleaner wrasse , there is only one male for every group of 6-8 females. If
SECTION 20
#1732783333010484-405: The sex ratio reverses, with 81 older men for every 100 older women; across all ages, the global population is nearly balanced, with 101 males for every 100 females. In most species, the sex ratio varies according to the age profile of the population. It is generally divided into four subdivisions: These definitions can be somewhat subjective since they lack clear boundaries. Sex ratio theory
