2-й рог у индийского носорога - простая аномалия или же атавизм?

Ещё об искусственных рогах.

Обезображенному браконьерами носорогу пересадили кожу слона

"...Незадолго до этого браконьеры подстрелили 12-летнюю самку носорога по кличке Надежда (англ. Hope) в парке диких животных провинции Квазулу-Натал (KwaZulu-Natal) в ЮАР. Они намеревались вырвать у нее рога, которые высоко ценятся на рынке материалов для украшений и лекарственных препаратов. После того как самка упала, неизвестные нанесли ей глубокие раны и разрушили кости в попытке извлечь рога, оставив, по сути, лишь мягкие ткани.

Что за нелюди такое делают.....

Сифака :

Кстати, к чему фото индуса, что тут комментировать?

Клыки же. Фотку чуть обрезать, и для обывателя это вообще станет бегемот.

Последний самец суматранского носорога из зоопарка Цинциннати скоро уедет на родину.

Всем доброго времени суток!
Меня интересует сколько всего индийских носорогов.В википедии пишут что 2500, на сайте wwf - 3000, на сайте всемирного фонда носорогов 3345 особей.Так сколько всего индийских носорогов как Вы думаете?

Разумнее всего ссылаться на последний источник.

Тем временем: засняты детёныши яванских носорогов!

Я читал что в национальном парке Казиранга 1855 особей индийского носорога. Как Вы думаете это правда или нет, может ли быть столько носорогов на площади 430 квадратных километрах?

В следующем году родится ещё один суматранский носорог. Но по закону подлости он, скорее всего, окажется бесполезным самцом.

Серый варан :

Почему бесполезным?

Из всех самок в неволе только одна достоверно фертильная.

Зачем же их кастрируют?

Status and Monitoring of the Greater One Horned Rhinoceros
in Dudhwa National Park life span
In the wild, rhinos can live up to 30-35 years,
and in captivity up to 40-45 years.
Tigers (panthera tigris) prey on calves upto
the age of six months; there were cases of
unsuccessful attempts by tigers on one year
old calves. Interestingly, there were two
cases of a tiger attacking adult female rhinos,
succeeding in one case, while in one case the
rhino was rescued before she succumbed
to her injuries and was released upon her
recovery.
Aside of these of cases, the only predator
to rhinos are humans. Rhinos have been
hunted over the last centuries for sport and
for its horn.

THE ECOLOGY AND BEHAVIOUR
OF THE
GREATER ONE-HORNED RHINOCEROS
William Andrew Laurie
"...Among carnivores, there are about 30 tigers distributed throughout
the park and a few more in surrounding areas. Chital are their most
important prey (Sunnquist and Tamang, 1976), but the tigers also take
rhino calves (Section 3.8.1) ..."
"...Causes of death included poaching (now largely controlled), tiger
predation (on the calves only) , intraspecific fighting (mainly among
males) and senility..."

Predation by tigers on rhino cows and calves is belleved to be an important factor in keeping down the population of rhinos in Gorumara and Jaldapara.

1952 Gorumara 2 (mother with calf)Похоже, это как раз тот самый случай :

“About November, 1951, a cow-rhino
with a very small calf was frequently seen. A tiger was
after this calf, and one afternoon in early December…
the tiger went for the calf. The cow at once charged the
tiger, and a fearful battle ensued about 300 yards from
the platform… the battle was inconclusive. About three
weeks later I saw the cow-rhino and her small calf again.
The calf looked normal, but the cow was emaciated, bore
deep claw marks, on both flanks, and seemed to walk
slowly with some difficulty. In the third week of January
1952, the second and the concluding round of battle was
fought during the night, and the poor, much weakened
rhinoceros was killed together with her calf… I found
the remains of the two animals on the right bank of the
Indong, a little upstream of Gorumara. This time there
were two tigers, and the calf had been completely eaten
together with about a third of the cow.”

CHAPTER 3
POPULATION STATUS AND DEMOGRAPHY OF
RHINOCEROS IN SAURAHA SECTOR, CHITWAN
NATIONAL PARK
Detail informations on death of rhinoceros were collected regarding poaching
(by gun-shooting, poisoning, electrocution, pitfall, firearm etc) and natural
death (old age, tiger predation, infighting, disease, rhino charge, flood and
mud sink etc.) from the records of DNPWC. Location, nature, time and date of
deaths were recorded categorically for each individual.
Natural mortality is a rare phenomenon for large, long-lived and endangered
herbivores (Dinerstein, 2003). In reality, human induced adult mortality is the
key problem for the conservation of large mammals. Large mammals are long
lived and comparatively slow breeders, so, they suffer rigorous declines in
their populations if excessive hunting and poaching occur.
As calves become prey for tigers, most of the calf mortality takes place during
the first year of life. The competition for mating with female contributes
majority of deaths among adult males. Mortality from disease rarely recorded
in rhinoceros. But, the transmission of disease among wildlife is quite serious
threat to the existing populations hence transmission options to build up few
other populations were undertaken in Nepal.

Meanwhile, the removal of rhino horn powder from traditional Chinese pharmacopeia in the 1990s had largely doused demand. In the early 1990s, for instance, horns sold for only $250-500/kg (pdf, p.85). And only around 15 rhinos were poached in South Africa each year from 1990 to 2007.

But things started changing in 2008. That year, 83 were killed, followed by 122 the next year. By 2012, that number had hit 688. Here's a look at how many rhinos were killed, on average, each day:

Paradoxically, the world's dwindling rhino population threatens only to make this worse, as diminished supply makes prices climb even higher. Given that one of the things driving demand is the perceived luxury of the item, higher prices alone are unlikely to snuff out demand. And with a single horn fetching as much as $300,000, the risk of being caught probably seems to many poachers to be one worth running.

That's probably why the fight against poaching is something of a losing battle. Though South Africa has done an admirable job of protecting its white rhinos, 668 were poached there in 2012--a 50% increase on 2011. And as we discussed recently, other countries may soon use drones to foil poachers, so dire is the problem.
