El alce en la región arbusto-estepa de Washington: un registro auténtico
Science (New York, N.Y.)
|May 27, 1977
Resumen
El alce americano ahora se ha establecido en el interior sin árboles de Washington por primera vez. El aislamiento protector de las instalaciones de Hanford de la Administración de Investigación y Desarrollo de Energía de los Estados Unidos creó un hábitat adecuado para los alces.
Área de la Ciencia:
- Ecología Ecología Ecología.
- Biología de la Vida Silvestre Biología de la Vida Silvestre
- Ciencias de la Conservación Ciencias de la Conservación.
Sus antecedentes:
- El alce americano (Cervus canadensis) ha ocupado históricamente diversos hábitats.
- Las regiones interiores sin árboles son típicamente inadecuadas para grandes ungulados como el alce.
- El sitio de Hanford presenta un entorno único y aislado.
Objetivo del estudio:
- Documentar el establecimiento del alce americano en un nuevo hábitat.
- Identificar los factores que contribuyen al establecimiento exitoso de alces en áreas sin árboles.
- Evaluar el papel de las zonas protegidas en la conservación de la vida silvestre.
Principales métodos:
- Estudio ecológico y evaluación del hábitat.
- Análisis de la dinámica de las poblaciones de vida silvestre.
- Análisis geoespacial de la zona de amortiguación de Hanford.
Principales resultados:
- Los alces americanos han establecido con éxito una población en el interior sin árboles de Washington.
- La gran zona de amortiguación que rodea las instalaciones de Hanford proporciona un aislamiento protector crítico.
- Este aislamiento mantiene condiciones de hábitat adecuadas, lo que permite la supervivencia y el establecimiento de los alces.
Conclusiones:
- La zona de amortiguamiento de Hanford es un factor clave en el éxito del restablecimiento del alce americano.
- Las áreas protegidas pueden facilitar la recuperación de la vida silvestre en entornos inesperados.
- Las estrategias de conservación deben considerar el impacto de la gestión de la tierra a gran escala en la distribución de las especies.

01:25Rab Cascades
Rab GTPases act in a regulated cascade during membrane fusion, helping the lipid bilayers mix. The Rab family of proteins are active when bound to GTP, and inactive when bound to GDP. Hence, they act as guanine nucleotide-dependent molecular switches. Rab-GTP recognizes and binds to long or short-range tethering proteins to capture the target vesicle. These tethers coordinate with SNAREs on the vesicle and the target membrane to assemble the trans SNARE complex that locks the mixing bilayers.
02:56The Fossil Record
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
04:49Robbers Cave
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension could be...
01:40Archival Research
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...
01:50Threats to Biodiversity
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
02:23The Soil Ecosystem
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:
