LOCATION
Black Gap is located in Brewster County just northeast of Big Bend
National
Park
(Map).
It encompasses a 20 mile stretch of Route 2627 which passes through the
Black Gap Wildlife Management Area, from which the locality derives its
name.
It should be noted that the Wildlife Management Area is off limits to
collecting,
however other public and private land exists in the area where
collecting is
legal.
COLOR/PATTERN VARIATION
Alterna from the Black Gap area are considered by many to be some of the
most
ususual, bizarre, variable and beautiful of any population of alterna.
Examples of the bizarre and unusual include a patternless snake
(bgp96a0001)
and a heavily triple alternated alterna (
bgp98a0001),
both collected by
Chris Sheldon
in the early 90s; and
a washed out, speckled alterna ( bgpfor0002
) collected
by Mike Forstner also in the early 90s.
Examples of the beautiful include a dark gray blairs with tomato red
saddles
(bgpmil0001)
collected by
Dennis Miller
in the early 70s; and a light gray, bright orange
blairs
(bgp93w0002)
I collected in '93.
As expected with the highly variable
nature of alterna, mixed in with the outstanding specimens are ordinary
specimens.
On average though, the Black Gap population seems to have
a relatively high percentage of quality specimens compared to other
populations.
Classic color/pattern characteristics that are widely recognized for Black Gap are heavy white bordering, washed out colors (e.g., bgp96a0002, bgphol0001 ), very bright colors, and white flecking in the orange (e.g., bgphdg0001). On average Black Gap alterna have heavier white bordering than any other population. The white in some spectacular cases can border virtually every black mark, including the speckles. (e.g., bgp97c0402 ) The blairs/alterna ratio is roughly 50/50. The gray is medium to dark on 90% of specimens and light on the remaining 10%. The black bordering of saddles is typically narrow, compared to the Eastern populations. For example, compare bgp97c0303 (Black Gap) with lomdoh0004 (Loma Alta). This narrowness of black is shared by the other nearby populations (Sanderson, Christmas Mountains, River Road). Bow-tie shaped saddles, where the orange is constricted along the spine, are not uncommon (e.g., bgp95c0103, bgphdg0001 ). This characteristic is also not unusual in Christmas Mountains alterna but is rare outside of Brewster County. Diamond shaped saddles occasionally occur (e.g., bgphol0001 ), but are not nearly as common as they are further west on the River Road and in the Davis Mountains. Speckling and triple alternates are also common (e.g., bgp97c0401, bgp97c0602, bgp98a0001 ). The speckling of Black Gap snakes often has a different look compared to other western populations due to the greater about of white bordering. For example, compare bgp97c0402 (Black Gap) with riv96a0001 (River Road).
RARITY
Alterna are very difficult to collect in the Black Gap area. Since the
early 70's, when
Dennis Miller
collected the first known specimen, approximately
40 have been collected
(see the Black Gap Wildcaught Table).
Two thirds of these have been collected since 1990, when many collectors
started
targeting the area.
During this latter period, an average of less than 4 specimens per year
have been taken.
The maximum number taken in a given year was 6 (1992). To put this into
perspective,
approximate maximum yearly takes for other localities are as
follows:
Langtry, 200;
Loma Alta, 80;
Sanderson, 40;
River Road, 30;
Christmas Mountains, 14;
Davis Mountains, 12;
Alpine, 10;
Carlsbad, 1;
Hueco Mountains, 11.
Rarity increases dramatically from east to west and to a minor extent
from low to high
elevation.
From the longitude and elevation alone, it would be expected that
alterna would
be more common than they actually are in Black Gap.
The most likely explanation for the rarity is habitat.
Very little prime habitat intersects Route 2627 where most collecting
activity takes place.
Outcrops of limestone and volcanics are few and far between and
secondary habitat
consisting of rolling alluvial deposits is less than ideal because it is
situated far
from any prime habitat.2
Moisture is well known to be important for alterna.
Some have conjectured low precipitation might be another factor in the
rarity. Significant
Mountain ranges occur to the south and east in Mexico. These could
presumably could create
a rainshadow over black gap, limiting the influx of moisture from the
Gulf of Mexico and
to a lesser extent the Pacific. While this might be true, the very
limited amount of
climate data for the area suggests that this is not the case. Black Gap
appears to receive
amounts of rainfall similar to what is received on the River Road.
Adding to the difficulty of obtaining specimens from the wild, poor adaptation of many of the wildcaughts has made the establishment of the captive population of Black Gap alterna very slow. It is generally believed that wildcaught alterna from the western part of the range are more heavily parisitized than the eastern populations, and as a result the odds of them surviving and adapting to captivity are lower, especially without treatment. It is not unusual for a wildcaught to do well initially, only to become a very sporatic feeder or, in some cases, terminally go off feed. Of 10 females collected in the last 10 years, 4 are are dead and a fifth specimen has never produced. In '97 there were only 3 wildcaught females that produced offspring.
MY COLLECTION
My collection of Black Gap alterna is by far the largest and most genetically diverse
group in captivity. Thirty six specimens (18.18), including
eleven wildcaughts (8.3), make up the collection. Seventeen of these are adults (10.7).
Highlights of the collection are a patternless specimen, which is
discussed at
length below,
a pair of cb98 anerythristics, also discussed below,
and an exceptional blairs
(bgp93w0002). This blairs has wide vivid
orange on a light
gray background. Several knowledgeable collectors who have seen this
snake in
person have commented that it is the most outstanding blairs they have
ever seen.
My patternless specimen (bgp96a0001) as is very possibly the most unusual and valuable specimen of alterna ever collected. It has essentially no pattern, except for ventrolateral black marks and banding on the tail. The pattern appears to be genetic. The patternless "pattern" appears to be the end member of the progression of patterns from A) "speckled neck alterna" to B) "heavily speckled alterna with patternless neck" to C) "totally patternless snout to vent." As you go from "A" to "C", the rarity of the pattern increases dramatically. Speckled neck alterna are typical, heavily speckled alterna are rare and patternless alterna are almost unheard of - only 2 patternless alterna are known. In addition to my specimen, one was found many years ago on the river road (Nunley, pers. comm.). My patternless alterna consistently produces the highest quality hatchlings of any of my females. In 1998, she produced a daughter with a patternless neck and random speckles to the vent (bgp98c0301). The snake looks very similar to the mother is general appearance. I consider it to be one of the most spectacular alterna I have seen.
In 1998, I produced a pair of anerythristic alterna. These were produced from a wildcaught male bred back to his daughter. As far as I'm aware, these are the first anerythristic alterna ever produced 3. The female (bgp98c0701) is a blairs phase. With age her appearance is improving considerably. The gray is darkening and the saddles are lightening. She appears to be heading towards a spectacular dark snake with light gray saddles. The male (bgp98c0702) is an alterna phase and is not as appealing as the female.
HISTORY OF CAPTIVE PROPAGATION
2 Similar alluvial deposits of the Mud Flats on the River
Road produce considerably more alterna. A key difference between the
this area and Black Gap is
that prime habitat consisting of Vo1canic Hills is situated much closer
to the road.
As a result, alterna are more likely to be found in those alluvial
deposits.
3 Miraculously, two other breeders also apparently produced anerythristics
in 1998 from unrelated stock. A single 277 was produced from wildcaught parents and a generic
of unknown lineage was produced. I have seen photos of the generic and it
appears to be anerythristic, but have not seen photos of the 277. There are
also known to be anerythristic mexicana-alterna hybrids.
The first clutch of Black Gap alterna was produced by Troy Hibbitts in
1992. This milestone
occurred 20 years after the capture of the first specimen. Since Troy's
clutch, at least one has
been produced every year. In 1998, several clutches were produced. As of
this writing the only breeders to have
produced
Black Gap alterna are Troy Hibbitts, Charley Bentley, Brad Anderson,
John Siefer, Craig Hodgson, David Doherty and
myself.
1 These numbers were derived from my own knowledge and from
discussions with
Norman Nunley and Jeff Barringer.
