AbstractIn South-Kivu province, cattle farming is an integral component of farmers’ livelihoods and one of the few income-generating opportunities for smallholders. However, very few studies have been conducted to characterize smallholders’ cattle production systems. This study documents cattle production systems to better understand their current situation, constraints they face and opportunities they offer. For that purpose, an investigation was conducted based on a structured survey questionnaire and participatory interviews with 863 farmers in South-Kivu province. Collected data were analysed using factorial analysis of mixed data and clustering techniques. The results revealed three types of smallholder cattle farms differing mainly in their herds’ sizes and landholding. The first category is the most common and includes farmers raising small herds (6.3 ± 6.7 cattle) of local breeds in herding system (in this work, “herding system” refers to a rearing system for which the farmer drives and stays with his animals on pastures and fallow land during the day) and grazing fodder in community pastures, fallow lands and roadside grasses, while land constitutes a scarce resource. In the second category, some farmers have small tracts of land (< 5 ha) and others have large tracts (> 5 ha), but all have medium-size herds (45.1 ± 19.4 cattle) made up of local breeds, which they rear in herding system. They also exploit community pastures, fallow land and roadside fodder for animal feeding. The third and last category includes farmers with large cattle herds (78.1 ± 28.1 cattle) of local, crossbred and exotic breeds raised free range in the fenced paddocks on vast areas of land (> 5 ha) found in high-altitude regions. However, while being different according to the above-considered characteristics, the three categories of cattle farming remain extensive pastoral farms dominated by male farmers. Agriculture and/or animal husbandry are their main source of income while their livestock are also composed of goats and poultry, beside cattle. Still, the three farming groups require more inputs and improvement strategies for increased productivity in the challenging environment characterized by low land accessibility and high demand for milk and meat. Fodder cultivation and crop-livestock integration through agro-ecological systems as well as access to credit and extension services are the proposed strategies for the improvement of this economic sector.

RESUMENEn Honduras ocurren cinco especies de felinos, jaguar (Panthera onca), puma (Puma concolor), ocelote (Leopardus pardalis), caucel (Leopardus wiedii) y el yaguarundí (Puma yagouaroundi). Se comparó la composición de las cinco especies de felinos en 15 áreas naturales  protegidas, las cuales se agruparon en tres regiones con diferentes zonas de vida, ecosistemas y gradientes altitudinal siendo estas; la región Moskitia, la región Central y la región Caribe. Se evaluó la detección de felinos con la presencia/ausencia en cada área. Se realizó un dendrograma y un análisis no métrico multidimensional para comparar la similitud entre áreas protegidas y especies. El hallazgo significativo es la ausencia del jaguar en las áreas protegidas de la región Central de Honduras, donde posiblemente se ha dado su extirpación. El puma, el ocelote, el caucel y el yaguarundí, se registran en las tres regiones del país. Al comparar la composición de los felinos en las tres regiones usando el análisis de similitud, este presentó diferencias significativas entre las áreas protegidas evaluadas. La región Central mostró menor composición que la región del Caribe y la Moskitia. La región de la Moskitia hondureña se muestra como la región con mayor resilencia para mantener las cinco especies de felinos.Palabras clave: Composición, conglomerados, escalamiento multi-dimesional no métrico (nmds), análisis de similitud (anosim), disimilitud, Moskitia. ABSTRACTHonduras is territory of five species of cats, jaguar (Panthera onca), puma (Puma concolor), ocelots (Leopardus pardalis), margay (Leopardus wiedii) and the yaguarundi (Puma yagouaroundi). The composition of the five cats in 15 protected areas was compared grouped in three regions:  the Moskitia, Caribbean and Central region with different life zones, ecosystems and altitudinal levels. Cat detection was evaluated by presence/absence in each protected area. Cluster analysis and non- metric multidimentional scaling were used to compare similarity between protected areas and species. The significant finding is the absence of the jaguar in protected areas in the Central Region of Honduras confirming local extirpation. Puma, ocelots, margay and the yaguarundi are present in the three regions.  Comparing composition of cats between the three region using similarity analysis this presented significant difference between protected areas. The Central region showed a lower composition in cat structure that The Caribbean and Moskitia region. The Honduran Moskitia region showed a higher resilience to maintain the five cats.Key words: Composition, conglomerates, non-metric multidimentional scaling (nmds), analysis of similarity (anosim), dissimilarity, Moskitia.

RESUMEN: La Selva Maya es el bosque tropical de hoja ancha más extenso de Centroamérica, se extiende entre México, Guatemala y Belice. El jaguar y el puma, son los felinos más grandes de América. En esta zona viven simpátricamente por lo que se presupone segregación en alguno de los componentes de su nicho ecológico. En este estudio se analizaron y compararon tres de los componentes principales del nicho: dieta, uso de hábitat y patrones de actividad, con el objetivo de evaluar si existe segregación entre el jaguar y el puma. Para la obtención de los datos se colectaron excrementos de manera oportunista, y se utilizaron trampas de cámaras automáticas en cuatro áreas protegidas. Se analizo la zona de estudio, a través de sistemas de información geográfica para determinar las proporciones de distintos tipos de hábitat presentes, y se colectaron datos de abundancias de las presas. Se analizaron los patrones y en la dieta, en el hábitat utilizado y en el horario de actividad. Se determino que el jaguar tuvo una dieta diferente y mas amplia comparada con la del puma, así también que este consume en promedio, presas más pequeñas. Las presas preferidas por elpuma fueron, tres especies de venados y tepezcuintles. Para el jaguar fueron coches de monte, pizotes y armadillos. Ambas especies presentaron un patrón similar de uso de hábitat, donde el "bosque alto" fue utilizado proporcionalmente a su abundancia, y el puma evitó el "bosque bajo". En cuanto a los patrones de actividad, ambos prefirieron horas nocturnas para desplazarse, aunque el puma presento mayor variabilidad. Se observo que ambas especies no se segregan mutuamente, espacial ni temporalmente. La frecuente utilización del "bosque bajo" y su relación con las aguadas y arroyos, es un factor importante en el mantenimiento de poblaciones de grandes felinos en la Selva MayaPALABRAS CLAVE: Felidae, Panthera onca, Puma concolor, coexistencia, nicho ecológico, Selva Maya, segregación ecológica.ABSTRACT: The Mayan Forest is the largest tropical broad-leaf forest remainder in Central America which extends between Mexico, Guatemala and Belize. Jaguar and puma are the biggest American wild cats. In this area both live sympatric which suggest segregation in at least one of its ecological niche components. In this study I analyzed and compared three of the principal niche components: diet, habitat use and activity patterns, with the main objective of assess if occurs ecological segregation among jaguar and puma. To obtain the data it was collected  jaguar and puma’s scats in an opportunistic way, and was used automatic camera traps in four protected areas. I analyzed the study area by geographic information system (GIS) to determine proportions of different habitat types, and also I used  previous collected prey abundance data. I analyzed patterns in diet, in habitat use and temporal activity. I found that jaguar had a wider prey spectrum than puma; jaguar took (in average) smallest preys, consequently, diets were significantly different. Puma preferred deer, brocket deer and paca as main prey; in contrast, jaguar preferred collared pecari, coati and armadillo. Both predator species presented a similar pattern in habitat usage, in which "highland forest" was used accordingly with its availability and puma avoided "lowland forest". About activity patterns, both were more active in the night time, however, puma was more variable in this aspect. Both species did not show segregation spatially or temporally. KEYWORDS: Felidae, Panthera onca, Puma concolor, coexistence, ecologic niche, Mayan forest, ecologic segregation.
