“…Local ungulate populations have also been studied here (e.g., by Bodmer et al, 1988;Bodmer, 1990). Faunal studies based on the lower Quebrada Blanco often included observations made in the adjoining Reserva Comunal Tamshiyacu-Tahuayo, a protected area that extends from the headwaters of the Tamshiyacu and Tahuayo rivers across the hilly divide that separates the Amazon and Yavarí watersheds to the upper Yavarí-Mirím (Puertas and Bodmer, 1993;Hurtado-Gonzales and Bodmer, 2004). Faunal inventory work by Michael Valqui, formerly a graduate student based at the Florida Museum of Natural History (FLMNH), resulted in the first substantial collections of usable specimens from TahuayoBlanco watershed (Valqui, 1999(Valqui, , 2001.…”

“…In the Neotropics, the study of the impact of hunting on this group of animals has focused on the assessment of their populations, since the decrease in the number of individuals is a serious threat for exploited populations (e. g., Peres 1996;Bodmer et al 1997;Hurtado-Gonzales and Bodmer 2004;Reyna-Hurtado and Tanner 2007). However, other aspects of the exploited species, including their behavior, are still little known.…”

Hunters´ landscape accessibility and daily activity of ungulates in Yasuní Biosphere Reserve, Ecuador

Ungulates are one of the most important groups in terrestrial ecosystems across the tropics. Also, ungulates are an important source of protein for people who inhabit tropical forests, and numerous studies have been conducted to evaluate the impact of hunting on the size of ungulate populations. However, little is known about other potential effects of hunting on these species. This study aims to analyze the effect of landscape accessibility to hunters on the daily activities of ungulates in Yasuní Biosphere Reserve, a protected area located in the Amazon region of Ecuador. We compared activity patterns (i. e., distribution of hours of activity along the day) and activity levels (i. e., proportion of hours of the day that an animal is active) for five ungulate species (white-lipped peccary Tayassu pecari, collared peccary Pecari tajacu, red brocket deer Mazama americana, brown brocket deer M. nemorivaga, and tapir Tapirus terrestris) in four sites differing in the degree of access to hunters. To this end, in each of the four study areas, a grid of camera traps was placed within a polygon of approximately 100 km 2 ; traps operated continuously for three to four consecutive months. We recorded the date and time of detection for each species. Daily activity patterns and activity levels were estimated with kernel density analysis for circular data. Our work included a total of 9,506 effective trapping days for the four study sites, resulting in 1,063 separate records of the five ungulate species. In the four study areas, the brown brocket deer and the two species of peccaries concentrated their activity in daytime hours. The red brocket deer was most active in twilight hours, and the tapir was primarily nocturnal. At sites most accessible to hunters, the activity patterns of the collared peccary included a higher proportion of nighttime hours. The red brocket deer also seemed to increase the proportion of nighttime hours of its daily activity. The overall daily activity level was higher in the site with higher accessibility, but was statistically significant only for the collared peccary and the red brocket deer. Our findings include moderate statistically significant evidence suggesting that the access of hunters to the landscape influences the daily activity of ungulates in Yasuní. One species that is clearly affected by the access of hunters is the collared peccary, which becomes more nocturnal and increases its nighttime hours of activity when accessibility to hunters is higher. When our results are compared with other studies, it is evident that the species may display different behavioral responses to hunting, and that these responses may vary with the scale of analysis. This study was limited by sample sizes, which did not allow performing comprehensive analyses for all five species. To further understand the effects of hunting and other human activities on animal behavior, additional studies specifically designed for this purpose should be conducted.Los ungulados constituyen uno de los grupos de mayor import...

“…In addition, current information regarding game meat consumption in rural and urban areas in the Amazon is concentrated near easily accessible cities, whereas remote communities and isolated cities have rarely been included in relevant studies (e.g., De SouzaMazurek et al 2000, Hurtado-Gonzales andBodmer 2004). All of these factors hinder our understanding of the large-scale effects of hunting and trading target species in the Amazon.…”

ABSTRACT. Chelonians constitute an important source of food and income for the inhabitants of tropical forests. We assessed the social, biological, and environmental factors affecting the hunting and trade of the endangered yellow-footed tortoise (Chelonoidis denticulata) in rural and urban areas in the Amazon and estimated the sustainability of tortoise use. We also discuss possible conservation alternatives that are compatible with the needs of local inhabitants. We monitored tortoise hunting and trade for 12 years in 10 traditional communities that exploit different habitat types in the Brazilian Amazon and collected data on the tortoise trade in two urban markets for six years. In upland forests, tortoise hunting mainly occurred during the dry season; in whitewater flooded forests, hunting mainly occurred during the flood season. The tortoise trade was carried out nearly entirely by whitewater flooded forest users and was intimately related to fishing, the main economic activity in these communities. Furthermore, the tortoise trade was encouraged in whitewater flooded forests because this environment yielded significantly heavier tortoises than upland forests, and we observed a strong relationship between trade probability and tortoise size. The tortoise trade was found to primarily supply nearby urban centers, generating high monetary gain. Female tortoises suffered greater hunting pressure and were more valued in the bushmeat market. The productivity of tortoise hunting in the monitored communities severely decreased with time. In addition, the price per kilogram of tortoise greatly increased in the urban market. Given this unsustainable scenario, policies regulating tortoise hunting in the Amazon are needed. These policies must be adapted to the different patterns of tortoise use by rural communities while maintaining the culture and food sovereignty of the local inhabitants.
