AbstractOcelots were historically hunted for their skins but habitat loss is now their most serious threat, causing rapid declines in populations throughout their range. Ocelot abundance has been estimated for various locations across the Neotropics, but we still lack this information from some countries, including Ecuador. Knowing whether ocelot abundance is increasing or decreasing is important to assess the conservation status of this species and the conditions of its habitats in the Ecuadorian Amazon and in the region. To determine whether ocelot abundance and its behavior are affected by human-related activities, camera-trap surveys were carried out in two localities of Yasuní National Park (YNP), one that has experienced hunting, oil extraction, and roads (Maxus Road) and one that is largely unaffected by these activities (Lorocachi). During the survey, 35 and 36 individual ocelots were photographed in Maxus Road and Lorocachi, respectively. Population density estimates were similar for both localities, ranging from 0.31 (SE±6) to 0.85 (SE±17) ocelots/km

La colonización dirigida, espontánea y estratégica, además de la permanente ampliación de la frontera agrícola para la extracción de recursos naturales, han determinado el uso y zonificación del espacio amazónico en los últimos 50 años. Las drásticas huellas socio-económicos, culturales y ambientales generadas por estos procesos han impactado negativamente la vida de los pueblos ancestrales y la naturaleza. Una consecuencia drástica es el cambio de la comprensión de la territorialidad en el interior de los territorios indígenas, y de la percepción que de aquel cambio tienen el Estado y los actores asentados en el entorno territorial comunitario. El presente estudio aborda el caso del pueblo waorani e inquiere cómo la ampliación de la frontera extractiva intensificaría los impactos negativos del proceso de desterritorialización en el Parque Nacional Yasuní, poniendo en mayor riesgo la integridad física y cultural de los de los pueblos que viven en aislamiento voluntario: Tagaeri y Oñamenane u otros de los cuales no se tiene referencia.   Abstract Targeted, spontaneous and strategic colonization, in addition to the permanent expansion of the agricultural frontier for the extraction of natural resources, has determined the use and zoning of the Amazonian space in the las 50 years. The drastic socioeconomic, cultural and environmental impacts generated by these processes have impated negatively the life of the ancestral peoples and nature. A drastic consequence is the change of the understanding of the territoriality in the interior of the indigenous territories, and the perception that the state and the actors settled in the community territorial environment have of that change. This study addresses the case of the Waorani people and inquires how the expansion of the extractive frontier would intensify the negative impacts of the process of decentralization in the Yasuní National Park, putting at greater risk the physical and cultural integrity of the peoples living in voluntary isolation: Tagaeri and Onamenane or others of which there is no reference.

Total Species

Lianas of Yasuní National Park and the Huaorani Ethnic Reserve, Ecuador were sampled using 0.2-ha subsamples from 12 1-ha plots. Using surveys and herbarium collections, the total species richness of lianas in the park and reserve is estimated to be close to 500 species. Terra firme habitats are significantly more species rich than floodplain habitats, but density of stems is not significantly different between habitats. The most abundant liana species is Machaerium cuspidatum Kuhlm. & Hoehne (Fabaceae) in both floodplain and terra firme habitats, representing more than 10% of all stems in census plots. Analysis of rarity indicates that none of the liana species encountered on the 12 plots is rare in terms of geographic range, and many species are not rare in terms of population size or habitat specificity. The rank order of abundance, combined with the coefficient of variability in species distribution among plots, is used to identify the 38 species (an oligarchy) that dominate forests in Yasuní.

The Way

This chapter examines the way missionaries and the Waorani faced three issues arising from the relocations of the late 1960s and early 1970s, as well as from ongoing contact between the Waorani and outsiders: adequate land, literacy skills, and the Wao desire to imitate their lowland Quichua neighbors. Jim Yost and various Waorani laid the groundwork for parts of Wao ancestral territory to be set aside for Ecuador’s Yasuní National Park and for another large tract to be designated a Waorani Ethnic Reserve. SIL literacy specialist Pat Kelley worked with the Waorani to encourage literacy and native-authored literature in Wao tededo, the Wao language. While seeking to preserve their traditional territory and their language, many Waorani also began to imitate the customs of the more populous Quichuas in an effort to move up the social ladder of Ecuadorian society.

AbstractHerbaceous plants are often under-studied in tropical forests, despite their high density and diversity, and little is known about the factors that influence their distribution at microscales. In a 25-ha plot in lowland Amazonian rain forest in Yasuní National Park, Ecuador, we censused six species of Heliconia (Heliconiaceae) in a stratified random manner across three topographic habitat types. We observed distribution patterns consistent with habitat filtering. Overall, more individuals occurred in the valley (N = 979) and slope (N = 847) compared with the ridge (N = 571) habitat. At the species level, Heliconia stricta (N = 1135), H. spathocircinata (N = 309) and H. ortotricha (N = 36) all had higher abundance in the valley and slope than ridge. Further, H. vellerigera (N = 20) was completely absent from the ridge. Conversely, H. velutina (N = 903) was most common in the drier ridge habitat. The two most common species (H. stricta and H. velutina) had a reciprocal or negative co-occurrence pattern and occurred preferentially in valley versus ridge habitats. These results suggest that taxa within this family have different adaptations to the wetter valley versus the drier ridge and that habitat partitioning contributes to coexistence.

Coyotes (Canis latrans) in Yellowstone National Park (YNP) have lived in the absence of wolves (Canis lupus) for over 60 years. I examined whether wolf reintroduction in 1995 and 1996 in YNP influenced coyote vigilance and foraging ecology. From December 1997 to July 2000, my co-workers and I collected 1708 h of coyote activity budgets. Once wolves became established in the Park, they once again provided a continuous source of carrion in the Lamar Valley and we found that coyotes began feeding on carcasses throughout the year. Although we documented that wolves killed coyotes, it also became clear that surviving coyotes quickly adjusted their behaviors when wolves were present. When coyotes were near wolves or in areas of high wolf use, they fed on carcasses much more; however, they increased the amount of time spent in vigilance activities and decreased rest. There appears to be a trade-off in which wolf kills provide a quick source of food that is energetically advantageous to coyotes; however, attendant costs included increased vigilance, decreased rest, and a higher risk of being killed. Changes in the behavior of coyotes in response to the reintroduction of this large carnivore may ultimately have wide-ranging cascading effects throughout the ecosystem.
