CARNIVORES OF THE
CAATINGA REGION
Author: Cláudia Bueno de Campos – Biologist,
consultant to the Instituto Pró-Carnívoros (Pro-Carnivore
Institute). |

In
several biological groups there are species with the habit of feeding
on other animals. This habit is called carnivorous. Thus, there are
carnivorous birds, fish, reptiles, insects and even plants. However,
in scientific classification, carnivores constitute an order of
animals (Carnivora Order) belonging to the mammalian group (Mammalia
Class). The main characteristics differentiating mammalians from other
groups of animals are the presence of mammary glands, fur, and the
ability to regulate body temperature (warm-blooded animals). |
|
|
|
Carnivores were given this classification because of the habit of
feeding on live animals. Although some still maintain a totally
carnivorous diet, others have adapted to the different types of
food available in their habitats.
This explains the fact that some species feed both on other
animals and on plants.
They are animals of prey with a physical and physiological
structure that most often ensures the success of the hunting
actions on which their survival depends. They are intelligent,
agile and strong, with powerful claws and sharp teeth to tear
apart the skin and flesh of their prey. They are animals at the
top of the food chain, and therefore influence its structure by
preying on the species necessary for their survival.
For that reason, the species belonging to the Carnivora Order are
important indicators of the integrity of ecosystems, playing an
important role in the natural functioning of same. |

The species belonging the Carnivora Order are widely distributed
throughout the world and comprise fifteen families, of which six are
found in Brazil (Canidae, Felidae, Mephitidae, Mustelidae, Procyonidae
and Otarridae). Within these families, 29 species are identified, of
which 17 are found in the Caatinga region, the main biome in
North-east Brazilian (Table 1) and one of the most endangered in
Brazil. Among the species present in this biome, there are two of the
largest predatory animals in the world, the onça-pintada or
jaguar (Panthera onca) and the onça-parda or puma (Puma
concolor).

* Speothos venaticus (“vinegar dog”): this species was not
recorded in any caatinga region, but in an ecotone region, that
is, a transitional region between various types of vegetation, of
which the caatinga is one. For that reason, we mention here the
occurrence of this species. |

Despite their ecological importance, the great majority of
carnivores are endangered by various forms of pressure coming from
human activities, such as sports hunting, hunting for the illegal
fur trade and traffic in live animals, and hunting by rural
producers because of economic damage to domestic livestock.
However, the destruction or alteration of their habitats for many
different purposes, such as road construction, illegal removal of
timber wood and agriculture that is not properly organized are the
main threats to this group, and may cause, among other damage, a
reduction in the local quantity of prey, in usable areas and in
the exchange of genetic material.
For that reason, research involving the collection of data on
carnivores under several approaches, such as feeding habits,
reproductive behavior, genetics, distribution, and conflicts with
human beings, is important in order to obtain knowledge that may
be used as a basis for action plans for the preservation of
predatory species, of prey and of the region under study; for a
reduction in conflicts between humans and predators; and also to
help to reduce economic losses. |

Following the trend of actions implemented by several private
institutions in Brazil and worldwide, with the objective of preserving
natural resources, Fazenda Tamanduá (2500 ha), located in Santa
Terezinha, State of Paraíba, has taken another initiative to seek
information on the fauna that exists in the region, carrying out a
survey of the fauna comprised by medium and large mammals. The survey
was effected by the Pro-Carnivore Institute (www.procarnivoros.org.br),
with the technical support of CENAP/ICMBio. The following species were
identified in the first phase of the work: Cerdocyon thous,
Euphractus sexcinctus, Kerodon rupestres, Leopardus pardalis,
L. tigrinus, Mazama gouazoubira, Puma yagouaroundi, Procyon
cancrivorus, which are indicated in Table 1 by the letter “T”.
This work will update the list of species found in the region, showing
that it is possible to restore the fauna within a certain area and
consequently local biodiversity. It can also be used as a basis for
future scientific research. |

Within the history of Fazenda Tamanduá – which is a reference in
organic and biodynamic farming and maintains under preservation almost
one third of the farm’s area, including a 325 hectare Private Nature
Reserve (“RPPN”) and legal reserve areas – one can find information on
actions to preserve both the fauna and flora, showing the concern of
the farm’s owner, Mr. Pierre Landolt, with the environment of the
North-eastern sertão region. |

The hunting prohibition, adopted since the farm was first bought
at the beginning of the seventies, was the first positive local
impact, because it enabled the recovery of the existing animal
populations over time. That decision restored balance to the local
food chain, which shows the importance of this type of attitude.
Since 1999, three studies have been carried out on the farm.
The first involved birds (Publication: Birds on Fazenda Tamanduá,
R.M.L. Neves and W.R. Telino Júnior); later A.C.A. Moura carried
out a study on mammals (not published); and in 2000 a phyto-sociological
survey of the RRPN was carried out and published by L.V.C. Araújo.
Continuing the preservation work, the mocó, or rock cavy (Kerodon
rupestres), a rodent typical of the caatinga’s rocky
regions, was successfully re-introduced in some areas where it was
no longer seen. |
