The Attribute of Adaptability

My Take Tuesday: The Attribute of Adaptability

The Rocky Mountain elk (Cervus canadensis) became the official State animal of Utah in 1971. Called ‘wapiti’ by the Shawnee Indians, elk are members of the deer family and associate closely with the deer and moose of Utah.
 
Elk, no matter what time of year, are a remarkable sight. So large in stature, these animals have become an admired icon of the American West. Elk are amazingly adaptable and can live almost anywhere—forests, deserts, mountains, and plains. They eat a wide variety of plants. Their typical diet consists of grasses (year-round), woody plants (winter) and forbs (summer). This adaptability is unique and ensures the species survival.
 
As a child growing up near the Manti LaSal National Forest, I frequently encountered these animals in the wild. I remember camping in the crisp early fall. The tranquility of those nights is unparalleled. The silence was only occasionally broken by the high pitched shrill of a bull elk – a guttural cry unique to this species. It is a sound that will hasten the heart rate of even the most seasoned of outdoorsmen. The sound echoes through the pines. Such an experience is breathtaking.
 
As a veterinarian, I am privileged to be able to work with a number of herds of elk. I very much enjoy this. Pictured is a herd of elk near Tooele, UT.
This animal is a symbol of power and strength. It is also a symbol of ultimate freedom.
 
We can learn a lot from elk. If we were as adaptable as this species, we would thrive in any situation where we are placed. We would be unafraid, undaunted, valiant and courageous.
 
When I am confronted with changes in life, I always think of the majestic elk.
 
And that is my take.

The Plasticity of Parturition

My Take Tuesday: The Plasticity of Parturition

Mongolian gazelle (Procapra gutturosa), are a medium-sized antelope with a heart-shaped patch of white fur on their rump. They are among the last great herds of migratory wildlife. Over 1.5 million of these antelope migrate across the vast expanse of Mongolia’s Eastern Steppe—the largest intact grassland in the world—as they search for forage throughout the year.

Herds of as many as 100,000 gazelle are commonly seen across the steppe with larger congregations occasionally reported. During the two weeks of the calving season, up to 400,000 females will gather, and the vast majority will give birth within a four-day period. This is a unique phenomenon. This is thought to be a strategy to reduce neonatal death loss due to predation. This synchronicity also ensures that the young will grow big enough by winter to survive the harsh weather.

Some studies also hypothesize and attribute the synchronization of parturition to plant phenology, with birth occurring when there is maximum available forage.

This synchronization of parturition has been described in reindeer, caribou, alpacas, wildebeest and many other migratory species. It has also been described in other species such as the banded mongoose. Induction of parturition among animals varies greatly, but nearly all of them involve progestagens, estrogens, progtaglandins and oxytocin. These adaptations are not only beneficial to the offspring, but are mutualistic for the dam as well.

Nature has created many adaptations that we are just beginning to understand. Over thousands of years, these species have survived because of these unique adaptations. As we learn more about exactly how this phenomenon occurs, it will have a significant impact on use in species conservation and agricultural animal production.

Clearly, the future of this technology in the conservation of endangered species as well as in agricultural production will rely on our developing a better understanding of the interaction of reproductive function with such diverse aspects of animal management as behavior, nutrition, stress and genetics. Who knows, perhaps this technology application can also help humans.

And that is my take.
