Texas Big Bend and the Davis Mountains April 22-29, 2017
Texas Big Bend and the Davis Mountains Participants: Anne, Craig, David, Frank, Hilary, Jan, Joan, Judith, Lori, Linda, Neil, Skip and Stephen April 22-29, 2017 GUIDES Woody Wheeler and Lynn Tennefoss Sunset through "The Window" at Chisos Basin, Big Bend National Park Day One: El Paso to McNary Reservoir, Balmorhea State Park and Fort Davis Appropriately, we started this journey on Earth Day. We departed from El Paso on an unusually cool but sunny day – ideal for travelling. El Paso and its suburbs swiftly gave way to the vast expanses of the Chihuahuan Desert. An hour east, and well into the desert, we exited off the freeway at McNary Reservoir. At the exit underpass, we found a small colony of Cave Swallows searching for nest sites. This was a life bird for many in our group. Nearby, we pulled into the completely unassuming McNary Reservoir. From below it appears to be a scrubby, degraded bank. Upon cresting the bank, however, there is a sizeable reservoir. Here we found Clark’s Grebes performing a small portion of their spectacular mating dance that resembles a synchronized water ballet. Western Grebes were also nearby, as were a variety of wintering waterfowl and an unexpected flock of Willet. Gambel’s Quail perched conspicuously and called loudly from the shore. Just as we were about to depart, Lynn spotted a lone Ruddy Duck bringing our total to 17 species of Gambel's Quail birds at our first stop. We stopped for lunch at a colorful Mexican restaurant in Van Horn that has hosted a number of celebrities over the years. -

STUDYING THE LIONS OF WEST TEXAS Photo by Jeff Parker/Explore in Focus.com Studies show that apex predators, such as mountain lions, play a role in preserving biodiversity through top-down regulation of other species. 8 TEXAS WILDLIFE JULY 2016 STUDYING THE LIONS OF WEST TEXAS Article by MARY O. PARKER umans have long been fascinated by Texas’ largest felines. Ancient rock art in Seminole Canyon State Park provides glimpses into this allure. There, in the park’sH Panther Cave, rock art estimated to have been created in 7,000 B.C. tells of a unique relationship between mountain lions and man. Drawings depict interactions between the felines and medicine men, while other images show humans donning cat- like ears. We don’t know what those ancient artists called the cats, but these days Puma concolor goes by many names—cougar, panther, puma, painter and, especially in Texas, mountain lion. No matter what you call them, we’re still just as interested in them today as were those prehistoric people long ago. Now, however, we use cameras and GPS technology to document both the mountain lions’ world and our own. Two modern-day researchers, TWA members Dr. Patricia Moody Harveson and Dr. Louis Harveson, director of Sul Ross State University’s Borderlands Research Institute, have been fascinated by the felines for years. In 2011, they began what’s casually known as The Davis Mountains Study. The project, generously funded by private donors, focuses on mountain lion ecology and predator-prey dynamics on private lands within the Davis Mountains.

Divaricating Plants in New Zealand in Relation to Moa Browsing
GREENWOOD AND ATKINSON: DIYARICATING PLANTS AND MOA BROWSING 21 EVOLUTION OF DIVARICATING PLANTS IN NEW ZEALAND IN RELATION TO MOA BROWSING R. M. GREENWOOD' and I. A. E. ATKINSON' SUMMAR Y: New Zealand appears to be the only country where spineless, small-leaved divaricating plants make up nearly 10% of the woody flora. Climatic explanations have been advanced to &ccount for the origin of these divaricating plants. We suggest that the divergent and interl~ced branching, the woody exterior and the tough stems of these plants are adaptations evolved in response to browsing by moas. Together with a few species of much smaHer birds, moas were the only browsing vertebrates in New Zealand prior to the arrival of man. Thq divaricate habit is probably only one of several strategies evolved by plants in response to moa browsing. However, because fioas fed in a different way from mammals there is little to support the idea that introduced browsing mammals have merely replaced moas as aQ ecological factor in New Zealand. MORPHOLOGICAL FEATURES OF NEW ZEALAND difficult. The most helpful keys are those of Bulmer DIY ARICATING fLANTS (1958) and Taylor (1961), which deal specifioolly The term Hdivaricating", indicating branching at with these plants.

Revitalization and Social Change: Contributions from Psychiatric Epidemiology
DOCUMENT RESUME ED 115 574 SO 008 808 AUTHOR Foulks, Edward F. TITLE Revitalization and Social Change: Contributions from Psychiatric Epidemiology. PUB DATE 75. NOTE 14p.; Paper presented at the, Annual Meeting of the American Anthropological Association (San Francisco, California, December 1975) EDRS PRICE MF-$0.76 HC-$1.58 Plus Postage DESCRIPTORS Behavior Patterns; *Change Agents; Culture Conflict; Literature Reviews; *Mental Illness; Psychology; *Schizophrenia; *Social Change; Social Influences; *Social Psychology; Social Science Research; Sociocultural Patterns ABSTRACT The relationship between schizophrenia and social change is examined through a review of recent medical research' in genetics, biology, and epidemiology. Those mental traits that today in our society characterize the schizoprenic, in a previous era or in another society may have provided a mechanism for cultural change during the periods of stress when traditional methods of coping with the environment proved unadaptive. In many cases, prophets, shamens, and seers experience the same estrangement and disorganization of the self =as does the schizophrenic" in our society. This perspective views schizOphrenia in our society as an evolutionary anachronism which in a previous society may have been organized early in youth and shaped into a socially useful form. Cultural change has in recent human history become a dominating ethos and is accordingly valued for its- own sake. The particular psychological functions of these sensitive individuals are therefore no longer used to transcend traditional points of view.

The Davis Mountain State Park : I Have Been Engaged in Bird Watching Over the Past Several Years, and During That Time Many Memb
The Davis Mountain State Park : I have been engaged in bird watching over the past several years, and during that time many members of the Audubon Society have recommended that I go and look at the beautiful birds at this or that State Park. It has been my experience that their recommendations are spot on and every visit has proven to be a fabulous birding experience. Several folks had suggested the Davis Mountain State Park and waxed eloquently about the wonderful birds to be seen there. A Lesser Goldfinch A Black Chinned Hummingbird How could there be a lot of birds in the Davis Mountains in the middle of the Chihuahuan Desert? Why would the birds come to this park smack-dab in the middle of absolutely no where? I was rather skeptical and didn’t plan a visit for the longest time. That is until the spring of 2014. We were going on a visit to the McDonald Observatory to look at the big skies of Texas and look at celestial objects through fabulous huge telescopes. I decided that since we were going to the McDonald Observatory a visit to the State Park was indeed warranted. So we set aside a full day to go hiking and some bird watching at the State Park. A Black Headed Grosbeak A Ladderback Woodpecker The Davis Mountains of Texas are located in West Texas about 6 hours drive from San Antonio on I 10 west till Fort Stockton, and then due south on Hwy 17 to Fort Davis. Davis Mountains State Park is a 2,709-acre state park located in the Davis Mountains in Jeff Davis County, Texas. -

Plant Structural Defences Against Browsing Birds: a Legacy of New Zealand’S Extinct Moas
OIKOS 104: 500Á/508, 2004 Plant structural defences against browsing birds: a legacy of New Zealand’s extinct moas William J. Bond, William G. Lee and Joseph M. Craine Bond, W. J., Lee, W. G. and Craine, J. M. 2004. Plant structural defences against browsing birds: a legacy of New Zealand’s extinct moas. Á/ Oikos 104: 500Á/508. Browsing by large vertebrates has been a major force in the evolution of terrestrial plants but Holocene extinctions of the browsers have left a legacy of broken biotic partnerships. Ratite birds were the largest herbivores in several regions, such as the moas of New Zealand. Many woody plants there have a distinct form of branching, described as ‘‘divaricate’’, with thin, wide angled, branches intertwining to form a tangled canopy. Divaricate branching has been interpreted as a form of protection against climate extremes or as an anachronistic defense against the extinct moas. Here we report the first experimental evidence that many of these plants are defended against extant ratite browsers. In feeding experiments on two tree species with different (heteroblastic) juvenile and adult branch morphology, emus and ostriches obtained adequate feeding rates from adult shoots but sub-maintenance feeding rates from juvenile shoots with the ratite-resistant traits. Divaricate juvenile shoots suffered 30Á/ 70% less biomass removal to the birds than adult shoots. Ratites browse by a distinctive clamping and tugging action. Structural defence traits that exploit the limitations of this feeding mode include narrow, strong, elastic branches that resist being torn off, wide branching angle (‘‘divaricate’’) that makes shoots difficult to swallow, and small, widely spaced leaves. -
