“…This suggests that A. seniculus may not be severely affected by fragmentation and habitat degradation in the short term, a similar result to previous studies at this site [Rimbach et al, 2013]. Alouatta spp.…”

“…exhibit a social system with a high degree of fission-fusion dynamics, and under normal conditions subgroup size is highly flexible. In small fragments with limited food resources, scramble and contest competition may prevent some individuals from gaining adequate nutrition, resulting in physiological stress [Rimbach et al, 2013] and limiting the number of individuals that can subsist in each fragment. In this study A. hybridus subgroup sizes were found to be consistently low, suggesting that only 'subgroups' were found in isolated fragments and few fusion events took place.…”

Many primate species currently subsist in fragmented and anthropogenically disturbed habitats. Different threats arise depending on the species' life history strategy, dietary requirements and habitat preference. Additionally, anthropogenic disturbance is far from uniform and may affect individual forest fragments in a single landscape in differing ways. We studied the effects of fragmentation on three species of diurnal primate, Cebus albifrons, Alouatta seniculus and Ateles hybridus, in Magdalena Valley, Colombia. We tested the assumption that generalist species are more resilient than specialist species to habitat degradation by examining the fragments' vegetation and spatial structure and how these affected primate presence and abundance patterns. We found C. albifrons, a generalist, to be the most abundant species in 9 of 10 forest fragments, regardless of the level of habitat disturbance. A. hybridus, a large-bodied primate with a specialist diet, was either absent or low in abundance in fragments that had experienced recent disturbances and was found only in higher-quality fragments, regardless of the fragment size. A. seniculus, a species considered to have a highly flexible diet and the ability to survive in degraded habitat, was found in intermediate abundances between those of Cebus spp. and Ateles spp., and was more frequently found in high-quality fragments.

“…Similarly, in two mantled howler groups residing in a recreational forest reserve of which a section is a zoological park open to tourism and that had been exposed to humans throughout their lives, daily number of people visiting the park did not infl uence fecal glucocorticoid levels (Aguilar-Melo et al 2013 ). In addition, fecal glucocorticoid levels in 31 red howler monkey groups residing in 10 different forest fragments also were not infl uenced by the level of human disturbance (i.e., minimal, logging, hunting, and logging and hunting), suggesting that howler monkeys might have a lower sensitivity to anthropogenic disturbance compared to other species such as spider monkeys ( Rimbach et al 2013b ).…”

Endocrine studies that investigate the interplay between hormones, behavior, and social and ecological environment are critical for our understanding of proximate, physiological mechanisms underlying the biology and sociality of a species. Nonetheless, only recently have endocrine studies been incorporated into research on howler monkeys ( Alouatta spp.), and only few aspects of endocrinology in 6 out of 12 species have been addressed. These include androgen and estrogen profi les of juvenile A. palliata , and progestin and estrogen profi les of the ovarian cycle of A. arctoidea , A. caraya , and A. pigra . In addition, socioendocrine studies in A. pigra and A. palliata have investigated how male androgen levels and male and female glucocorticoid levels are infl uenced by intra-and extragroup male-male competition, whereas ecologically oriented endocrine studies have revealed that in A. pigra , A. palliata , A. belzebul , and A. seniculus male and female glucocorticoid levels are infl uenced by a scarcity of high-quality food resources, habitat fragmentation, human disturbance, and translocation. Endocrine studies have shed light on howler monkey biology and sociality that were not anticipated based on behavioral data alone. This includes a nonaggressive form of intragroup male-male competition over access to females, a more prominent reliance on high-quality food resources such as fruits for these primarily folivorous primates, and an apparent higher sensitivity to social and ecological stress in females than in males. Additional endocrine studies across howler monkey species are needed to further elucidate relationships among diet, mating competition, and social interactions.Resumen Estudios endocrinológicos que investigan la interacción entre las hormonas, el comportamiento, y el contexto social y ecológico son fundamentales para nuestra comprensión de los mecanismos fi siológicos subyacentes a la biología y al sistema social de una especie.

“…Loss of appropriate environment, fragmentation and anthropogenic disturbance was behind a loss of biodiversity worldwide (Fahring, 2003). Although the main reason for the loss of diversity was a decrease in suitable habitats (Hannah, Carr and Lankerani, 1995;Foley et al, 2005), the importance of the influence of degradation of habitat should also be mentioned (Rimbach et al, 2013). The loss of orchids in Moravia and Silesia was described by Jatiová and Šmiták (1996), in the protected area of the Moravian Karst by Vaněčková et al (1997), and near the village of Křtiny in the central part of the Křtiny Training Forest Enterprise (TFE) by Jelínek (2009).…”

The aim of this study is to determine the relationship between some forest stand properties and the occurrence of orchids in the territory of the Křtiny Training Forest Enterprise. The research took place between the villages of Babice nad Svitavou, Kanice and Křtiny and largely spans the Moravian Karst Protected Landscape Area, partly in the core zone as well as the second zone of the Moravian Karst, where ordinary logging practices are used. Only a small part falls into the core area (first zone) -the two small-scale nature reserves with a total area of 61 hectares and a non-intervention regime. The selected area is situated mainly in forest ecosystems with beech and oak (Fagi-Querceta and Querci-Fageta) covering an area of 853 ha. The occurrence of orchids was examined in relation to natural conditions, forest type and forestry land use. In particular the occurrence of orchids to the height of the tree vegetation, to the Lidar Penetration Index and to the distance from roads and cleared boundary lines were investigated.
