MS configuration

6:39 - 9:48 Early morning ambi - at Hotel El Nogalito
crickets
roosters (good @7:07, 7:32)

NG 10:24 ambi at visitor's center - speaking in spanish - CB radio, cars in bg

12:25 JB - so what is the difference btwn native fish and endemic fish?

12:30 JM - endemic is a sub-category of native, which means that you don't find them anywhere else in the world¿12:41 endemic is a sub-category of native, and endemic species are native species, they are only found at a given site. So for instance, the endemic species of CC are only found here at CC which is why they are so important for conservation. Bc if we don't send them here then they are lost to the world. In contrast, native species naturally exist somewhere but they can often occur in many different sites or habitats.

13:10 JB - and whether the endemics are introduced and are a foreign species -

JM - and endemic species is never introduced - so endemic species are always native species that only exist in that locality. And exotic species is an introduced species that comes from somewhere else that was introduced - either - usually by humans into a site, so they don't naturally occur and that is why we are concerned about them bc they don't interact with the native species and can potentially compete with them, or prey on them and drive native species or endemic species to extinction. 13;45 and if you drive an endemic species to extinction then you have lost it forever bc it doesn't exist anywhere else on the planet.

13:53 JB these are 2 of the exotic species here

JM - those are 2 of the common exotic species, there are a few others, but the one fish you are looking at - heme cromis - is native to Africa. It has been in the basin now for 5 or 6 yrs, actually probably a little longer, and we are seeing it spread in the basin which is why we are particularly concerned about that exotic species.

JB - So some how this species is getting from one poza to another?

14:23 JM - yes, exactly.

JB - do we know how?

JM - we don't know how. There is some - we have two hypotheses. One is that someone actually put them in different pozas. The fish, it is a beautiful fish, it is very valuable in the aquarium trade, and so some people thought that someone thought they could grow them in their backyard, and then put them in a poza here and put them in a couple of different places. Alternatively, [CB in bg - tape no good] they can be transported in underground water connections, and we just don' know how the diff pozas are connected underground. So it remains a mystery. 14:56

14:57 JB - so somebody might have though I will use these as my fish farm and raise these expensive little aquarium fish for the doctor's office

JM - 15:07 exactly. Yeah

JB - Arturo, ready to show us around?

15:18 Art - yeah - talking in Spanish -

JB - in spanish - asking for an orientation of the area, and description of the area

MOVING TO THE OUTSIDE

G 15:53 - 16:34 walking on dirt road to the poza at visitor's ctr

16:36 JB - so, would you start off by saying your name, etc

16:47 Art - trying in english - but might be better in spanish

17:49 I am a biologist Arturo Contreras. I am chief of projects here in the natural protected area of CC, and my work here is to investigate about the natural resources in the valley and to promote investigation - to bring the people from the natural protected area --the inhabitants how to reach the sustainable development in the area and to put - his rich - ?? - for her projects.

18:47 JB describe to us where we are standing

19:06 Art - this is a small basin in the Chihuahuan desert it is located on the geographical center of Coahuila, the Mexican state of Coahuila. And this natural protected area was established to protect the several stages of flora and fauna which are unique among the flora and fauna of Mexico and of the world. We have more than 70 species which are found only here in this basin. 19:44

JB - and could you describe where we are standing¿.etc

19:59 Arturo - one of the important aspect of this natural protected area is that it is on the Chih. Desert, it has many springs, many lagoons, locally name is pozas. At this time there are more than 200 pozas and each of them is very different. It has diff ? temperature, color of the water, salinity, and the flora and fauna is diff - even - if 2 pozas are very close one might be with the fishes, the other no. ¿. And each pozas has diff conditions - ecological conditions which are unique among the pozas of the basin.

JB - it is unusal to find an oasis like this in the middle of the Chih desert or any desert?

21:24 Art - yes. The deserts are characterized by the absence of water and in the way of streams, springs, and here in this basin you can find many springs, and only in this basin, bc the closer basins next to CC has no springs, has no water and has diff flora and fauna that CC.

JB - how old are you?

Art - I am 38 yrs old

JB - and how long have you worked at this reserve?

22:17 Art - I have been working here for 16 months for the govt, but I come here in 1978 in vacations and in 1983 I began to collaborate in investigations here in CC.

JB - so you have been coming to CC since 1983 as a scientist and just as a visitor¿.why do you keep coming here? What is it about this place that draws you?

23:03 Art - first, CC has tourist interest bc has many springs, you can swim, you can dive to observe the fishes, the flora, the fauna from the pozas. You can work (walk) by the desert to know several of the plants. You can visit also the museums¿..

JB - asking something more personal - for YOU, why has it been drawing you back¿.? For 30 yrs?

23:48 Art - ok, my interest is very special bc I love CC the nature of CC the flora, the fauna, the - como se pais? (jane - the countryside) the natural beauty of CC. 24:20

JB - why don't you try that again in Spanish

24:29 - 28:38 Art - in spanish¿¿THERE MIGHT BE SOMETHING IN HERE TO USE - ABOUT THE BEAUTY of THE PLACE and WHAT MAKES IT SPECIAL¿the turtles, the fish, the snails - the importance of the SPRINGS

28:40 JB - look out here and tell us what we are seeing

28:43 Art - we are here located at the info ctr for visitors¿¿(he describes the vis ctr) 29:10 we have guides to explain the facts of CC¿..we have one of the richest pozas of CC bc this spring has the biggest diversity of fishes in CC¿ 29:57 in this poza easily you can find the Minkley Ciclid, which is an endemic species of the CC basin. This is very common, but it has a particularity. This fish is polymorphic which means the same species is different in morphology and the ¿¿ feeding habits bc some fishes feed on snails. Others feed on detritus, and other kind of this ciclid feeds on fishes. Also, we can see the ??/ of the ciclid¿¿.blue dots on the body, also you can find the catfish, also the bass, also several minnows, the Mexican mosquito fish and also the sun fish. Also you can find some tortoise and many different insects¿..we are standing on a platform¿there are islands in the middle where the tortoise go¿.also several plants. This poza is important bc 32:31 many people come to CC to know the endemic box turtle. The Coahilian box turtle, and this is very different from other tortoise of the same genus bc this is the only one which is aquatic -- all other box turtle's are terrestial. 32:57

JB - in the world?

Art - In the world.

JB - This is the only box turtle that swims in the world. Right here in CC

32:06 Art - and the origin of this species is some 40,000 this area was covered by forest and after the last glaciation the forest moved to the higher parts of the mtns and the animal species that lived in the flood lands need to move with the forests or to adapt to very dry conditions which were prevalent in the new basin and this species needed to enter the water to survive

JB - who was your father?

34:10 Art = My father was a biologist. This area is important for me bc the biological importance of CC was discovered in 1938, but the first findings were over looked ¿ until 1958 when Dr Minckley come here for the first time, and my father also a biologist come here several months later and they both made their efforts to protect the basin 34:59

JB - so your father had been coming to CC before you were born.

Art - yes

JB - did he used to bring you here?

35:07 Art - my father brings me to CC when I was a child, and I was always¿.amazing¿..

!! G 35:33 - 40:26 Art - SAYS THIS IN SPANISH (@40:11 the children coming in bg - as he talks about children

40:26-43:03 VG children in bg - in truck moving forward, children talking ¿¿

49:37 - why are you here?

50:22 51:30 ambi in area of intvw

52:03 - 53:30 ambi in area (same area) , under hut
