Please share your info on amur tigers.

One man (former employee of Zoo Prague) told me that there are basically two kinds of amur tigers. First - "real" amurs - are not exceptionally tall, but long and robust. Second - so called "Leipzig line" - are tall, but not so robust and not so heavy.

Do you have any info on this?

  The size of the Barbary lion
Posted by: Kingtheropod - 04-05-2014, 11:23 PM - Forum: Lion - Replies (71)
This topic was made by Guate at animalbattles board sometime ago. This is direct copy excluding the unimportant parts.

0 - Was the Barbary lion, the famous population in the north of Africa, a truly giant? Are those claims true? The next topic show that the Barbary lion was of the same size than they brothers of India and West Africa. None reliable weight has been reported from this population, but the few sizes and skull dimensions show that they are not exceptional in any particular characteristic.

1. Charles Guggisberg


It has been long debated which was the size of the Barbary lion. At this moment, the best source is the book “Simba, the life of the lion” of Charles Guggisberg (1961), check the image:


*This image is copyright of its original author


As we can see, the sizes reported are no larger than modern lions from East Africa, or a better comparison, of the same size than those from West Africa and India.



Some weeks ago, I buy the book “Wild Cats of the World”, also of Guggisberg (1975) and he put the same data about the Barbary lion that he puts in his previous book. Check the image:


*This image is copyright of its original author


So, I search the original source of the data which is this book:

* Brehm, A. E. 1925. Tierleben. Vol. 4. Leipzig.



After a few searches, I found it in the web here:

https://archive.org/details/brehmstierlebena12breh



The reference is different (year 1915, Vol. 12), but the data is exactly the same.

Now, check the measurements that Brehm states:


*This image is copyright of its original author



Brehm was probably one of the best Zoologists from Germany and the entire world. His data most be taken as mandatory and his statements are highly reliable, although now somewhat outdated.



Brehm states that the adult Barbary lions have a shoulder height of 80-100 cm, a head-body length of 160-190 cm and a tail length of 75-90 cm, which produce a total length of 235-280 cm. This size is similar to all the other lion populations and don’t present any exceptional dimension.

2. Nobuyuki Yamaguchi



Yamaguchi & Haddane (2002) made a good investigation about this lion, check it:



“How big was a Barbary lion? The famous French zoologist Cuvier measured a six-year-old captive-reared male Barbary lion, which had head and body length of 5 pieds 2 pouces (= c. 1.58 m), tail length c. 66.1 cm, height of forequarters c. 83.6 cm and of hindquarters c. 83.6 cm (Geoffroy-Saint-Hilaire and Cuvier, 1824). This lion was caught in eastern Algeria in 1795 at about one year old and died at ten years old in the Jardin des Plantes, Paris. Although the live lion may not have given Cuvier accurate measurements, the animal seems to have been very small for a male lion. It is, however, doubtful whether captive Barbary lions, usually captured as cubs and kept in menageries during the 18th or 19th centuries, attained the full body size. Cuvier himself referred to undesirable captive conditions at the menagerie (Geoffroy-Saint-Hilaire and Cuvier, 1824). Cornish (1899) reported that big cats only lived, on an average, for two years in London Zoo in the mid-1800s. Gérard (1856) also expressed his concern about the captive condition of lions at the Jardin des Plantes. On the other hand, he described a big wild Barbary lion he shot with the comment `This lion, compared to the finest of those which are exhibited in our menageries, or at the Jardin des Plantes, was what a horse is to a donkey. . .' There is, however, no credible record of body measurements of wild Barbary lions. Gérard (1856) described the size of wild male Barbary lions as c. 2.3 m from the tip of the nose to the root of the tail, which measured c. 90 cm, and their weight as c. 270–300 kg. If this had been true, Barbary lions would indeed have been big amongst lions. However, the methods of obtaining these measurements (e.g. straight or along the curve) were not specified, and the accuracy of the measurements themselves may be questionable, as Gérard made them in the field. Although Pease (1899, 1915) suggested that North African lions might have become very heavy because they fed on mutton so much, regarding the body length he seems not to have believed what he himself quoted – an Algerian lion whose head and body length was c. 2.5 m and the tail length 75 cm.”



“The largest Barbary lion skull so far measured, which is partly broken, has an estimated greatest length of c. 360 mm (Mazák, 1970; Yamaguchi, unpublished). Although 360 mm is not small, big skulls of sub-Saharan lions easily reach a maximum length of over 380 mm, and some even over 400 mm (Hemmer, 1974; Best, 1981; Yamaguchi, unpublished). Does this mean Barbary lions were not particularly big? Due to such a small sample size, we have to wait until more specimens may become available. The big lion Gérard shot in Algeria was presented to the Duchess of Orléans (Gérard, 1856), but the current whereabouts of this specimen and other wild-shot Barbary lions which decorated Gérard's Paris residence are not known.”

Source: http://www.izn.org.uk/Archive/321/Izn-321.htm#lion



Conclusion of Yamaguchi: there are no reliable sizes of wild Barbary lions, nor any weights. Yamaguchi, the “god” of hard-core-lion-fans presents a good case where he states that there is no evidence or at least enough specimens to say that this lion was larger than any other population. In fact, if we follow the new genetic evidence and with the presented sizes, we can conclude that this lion was of the same size and weight than modern Indian and West African lions, which incredible, reach the same sizes despite the large geographical distance.

3. Skull size

About the skulls, Yamaguchi & Haddane (2002), quoting Mazák, states that the largest skull from this population was of c.360 mm, which is smaller than the maximum of other lion populations (South Africa, up to 419 mm according with Hemmer (1974)). However, a new investigation of J. H. Mazák (2010) provides new figures, check the image:


*This image is copyright of its original author




This table presents the following average for the population in the north of Africa:

Greatest skull length:

* North Africa:

Males – 372.3 mm (n=3)

Females – 318.3 mm (n=2)



The second sample from North East Africa (specifically Ethiopia, including those from Addis Ababa) is dubious on its classification, because some authors believe that they are from descendents of the Barbary lion, but the last genetic study show that they are closer to the East African lions (Dubach et al., 2013), so its inclusion here will be incorrect.



Although small (n=3), the sample of Barbary lions show specimens that are clearly larger than the record stated by Yamaguchi, with a probable maximum between 410-420 mm. Even then, there are several records of lions with large skulls and small bodies, so this large skull size only suggest that Barbary lions were as large as other populations, but that they were no exceptional in any case.



Here are some images of a Barbary lion skull found in the tower of London:


*This image is copyright of its original author


*This image is copyright of its original author



*This image is copyright of its original author


*This image is copyright of its original author


Sadly, there are not measurements available, but they seem to be very small.



The average for the Indian lions is of 338.9 mm (n=6) according with Mazák (2010) and of 344.0 mm using 4 specimens from Pocock (1939) and Prater (1921). The largest Indian lion skull available measured 365.8 mm (Prater, 1921). Mazák (2010) presents only one skull of 330 mm from Iran and one of 347.8 mm from West Africa. Obviously these samples are pretty small, but even then, it seems that the Barbary lions had larger skulls than those from Asia and West Africa. Could this mean that the largest specimens of the Barbary lions were larger than those from these regions? Probably they did, but we don’t know by how much. A study of the relation between skull length and body length of lions could help us with this problem.


4. Conclusion



Using the little reliable information available, the Barbary lion (female and male) had a head-body length of 160-190 cm, a shoulder height of 80-100 cm and a greatest skull length with an average of 372.3 mm in males and 318.3 mm in females. These sizes are about the same than those of Indian and West Africa, with the exception of the relative larger skulls.



With the weight issue, judging by its body size and skull dimensions, Barbary lions probably weighed up to 200 kg (and much less in average, probably between 160-170 kg) although there is the possibility of some exceptional specimens of probably up to 230 kg like the East African lions, or even 250 kg like the Southern African lions, but this last figure will be probably just an exaggeration in the northern areas of Africa. There is only a single report of Gérard of males up to 270-300 kg, but these are simple estimations and are completely unreliable.



The idea of its large size came from the large mane, but there are several captive Indian lions with heavy manes that weight less than 160 kg. There are several large lions with heavy manes in private facilities available in the web and the hard-core-lion-fans proclaim without any evidence that they are “Barbary”, but the truth is that none of them is pure Barbary or from any other population. Besides, any captive lion in cold climate can develop a large mane, so the mane is the worst factor to detect a Barbary lion.

Barnett et al. (2009) confirms that Barbary lions and those from India are the about the same, genetically speaking.

Here is the image of the evolutionary tree of the three different taxas of “lions”, plus a little ad:

*This image is copyright of its original author


Interesting, the DNA analysis showed that Barbary and Indian lions are about the same, even more closely related than some Cave lion population between them (intra-specifically).



This supports even more, the theory of Thapar et al. (2013), that lions from India were originated from Africa, and that the particular population of Gir probably came from the lions exported by the Mughals and Alexander the great, which take them from North Africa and Persia.

  ON THE EDGE OF EXTINCTION - B - THE LION (Panthera leo)
Posted by: peter - 04-04-2014, 06:52 AM - Forum: Premier League - Replies (226)
INTRODUCTION AND STATUS

Although there are more wild lions (25 000 - 30 000, experts think) than wild tigers (about 3 000), lions have rapidly lost ground in the last decades. The population in Gir (India) is more or less stable, but in Africa the situation is different.  

Lions are protected in well-known reserves, but they struggle in regions where they have to compete with humans. In many parts of Africa, they are faced with loss of habitat and poachers.

How solve this problem?  

The answer was saltwater crocs in Australia, some thought. Although they eat humans at times, their skin was the main reason they were hunted close to extinction. How save wild crocs and meet the demand? Croc farms!  

Could lion farms be a solution for problems in Africa?

Not quite. Wild lions, in contrast to crocs, compete with humans in that they use similar regions. They also eat them at times. How solve these problems when it is also known big game hunters like lions? Lion farms!

The main advantage of lion farms is revenues. Revenues for those who invested in these farms in particular. As they only make money when lions are sold to zoos or shot by hunters, lion farming compares to any other business in that it is about making a few bucks in the end. True, the owners say, but locals profit as well and some hunters prefer farm lions over wild lions, thus limiting poaching. Farm lions are bigger and hunting them is way easier than hunting wild lions. Murder, opponents say. True, but it has an effect on poaching and poaching in Africa is very big business. Many species in Africa walk the edge as a direct result.    

This thread is dedicated to wild lions. Anyone with good information (old and new) is invited to share it here.

It's very likely all AVA forums will be deleted in the near future (reliable source). Former posters are adviced to copy (and paste) those threads and posts considered interesting. We could perhaps create a new board here to store posts and even complete threads.
