“…Compared to other traditional climbing methods like the use of climbing spikes, for example, that can be dangerous due to the significant weight of the equipment and the continuous contact with the trunk [9,12], the climbing technique with the use of ropes method has many safety advantages [9] and it has been widely reported in many studies [8,9,11]. Using the appropriate equipment like ascenders and descenders (Petzl ® stop descender model, Recreational Equipment, Inc., Seattle, WA, USA, for example) the climber can descend quickly in an possible emergency (in case wasps or bees attack, for example) and access the first branches of the crown more quickly and easily [44,45].…”

“…This method has been used and described in many surveys on tropical forests [8,9,11]. The diameters along the stem were measured at selected locations using a diameter tape (Forestry Suppliers ® , Inc., Jackson, MS, USA) and the merchantable height (H) was measured with a metric tape plugged to the climber.…”

“…In addition, the regeneration within permanent plots cannot be cut. Therefore, tree climbing techniques using ropes, as a non-destructive method, can be useful to collect the diameter along the stem and access the tree crown to collect seeds and branches [8][9][10][11]. This technique is different than methods that use climbing spikes, which can cause multiple types of injuries in tree rhytidome affecting their survival [9,12], particularly in tropical trees where the bark and the sapwood thicknesses are very thin [13,14].…”

Abstract:The Eschweilera genus has great ecological and economic importance due to its wide abundance in the Amazon basin. One potential use for the Eschweilera genus is in forest management, where just a few trees are removed per hectare. In order to improve the forest management in the Amazon, this study assessed two critical issues: volume equations fitted for a single genus and the development of a non-destructive method using climbing techniques. The equipment used to measure the sample trees included: climbing rope, ascenders, descenders, and carabiners. To carry out the objectives of this study, 64 trees with diameter at breast height (DBH) ≥ 10 cm were selected and measured in ZF-2 Tropical Forestry Station near the city of Manaus, Brazil. Four single input models with DBH and four dual input models with DBH and merchantable height (H) were tested. The Husch model (V = a × DBH b ) presented the best performance (R 2 = 0.97). This model does not require the merchantable height, which is an important advantage, because of the difficulty in measuring this variable in tropical forests. When the merchantable height data are collected using accurate methods, the Schumacher and Hall model (V = a × DBH b × H c ) is the most appropriated. Tree climbing techniques with the use of ropes, as a non-destructive method, is a good alternative to measure the merchantable height, the diameter along the stem, and also estimate the tree volume (m 3 ) of the Eschweilera genus in the Amazon basin.

-(Vascular epiphytes in Subtropical Ombrophilous Forest fragments, Curitiba, Paraná, Brazil). This study was carried out in 14 fragments of Araucaria Forest, with Cfb climate, precipitation 1,450 mm/year and annual average temperature 16.7 ºC. 96 native and ten exotic species were recorded in 21 families. Orchidaceae (35 species), Polypodiaceae (14 spp.) and Bromeliaceae (12 spp.) were the richest families. The number of native species in the fragments varied from ten to 64. Vascular epiphyte richness of Subtropical Ombrophilous Forest is lower than in tropical coastal rainforests but higher than in Brazilian seasonal forests. Climate type, forest coverage and degree and intensity of fragment disturbance are the most important aspects that interfere with the maintenance and expansion of epiphytic communities.Key words -floristic composition, subtropical forest, vascular epiphytes, urban forests RESUMO -(Epífitos vasculares em fragmentos de Floresta Ombrófila Mista, Curitiba, Paraná, Brasil). Este estudo foi realizado em 14 áreas de floresta com Araucária, sob clima Cfb, com valores médios anuais de precipitação de 1.450 mm e de temperatura 16,7 ºC. Foram registradas 106 espécies epifíticas (10 exóticas) distribuídas em 21 famílias. Orchidaceae (35 espécies), Polypodiaceae (14 spp.) e Bromeliaceae (12 spp.) apresentaram maior riqueza específica. O número de espécies nativas por fragmento variou entre 10 e 64. A riqueza dos epífitos vasculares em Floresta Ombrófila Mista é menor que em Floresta Ombrófila Densa, e maior que em florestas estacionais brasileiras. As variações climáticas, o tipo de cobertura vegetacional, o grau e intensidade de perturbação nos fragmentos são determinantes na manutenção e incremento das comunidades epifíticas.Palavras-chave -composição florística, epífitos vasculares, floresta subtropical, florestas urbanas

“…With a sling shot, we projected a thin lead-line across a major lower branch, tied our 10.5 mm main-line to the lead-line, and pulled the main-line over the major branch. A secondary line provided redundant safety, with rope feed to the climber being controlled at the base of the tree via a figure-8 belay plate attached to the harness of another researcher (Laman 1995).…”

Movement ecology of arboreal monkeys in Central America involves the action of diverse body postures to address challenges in rain forests, where scattered resources and complex habitat structure demand that a primate frequently employ extreme physical finesse to survive. What is not clearly understood about this area of study is the connection between primate body postures as responses to specific types of forest architecture and how forest structure may influence a monkey's continued capacity for wide-ranging mobility over time. We studied tree canopy structure and branch connectivity associated with the movement ecology of black-handed spider monkeys (Ateles geoffroyi), mantled howling monkeys (Alouatta palliata), Geoffroy's tamarins (Saguinus geoffroyi), and white-faced capuchins (Cebus capucinus) in Panama and Costa Rica. Laboratory study of primate cadaver pelvises was done at UC Davis, Oregon Osteology Lab, and the Denver Museum. Rain forests appear to induce wide-ranging leg movements in wild neotropical monkeys that were not observed in the same species of monkeys inhabiting artificial environments. We also found that a wild primate employs frequent wide-ranging leg movement that result in widely dispersed contacts between the articulating surfaces within the hip, potentially maintaining cartilage and contributing to the longevity of that joint. Thus, a connection may exist between rain forests, the leg action of wild monkeys, and the continued capacity to move over time in this group of long-lived animals. postures as responses to specific types of forest architecture and how forest structure may influence a monkey's continued capacity for wide-ranging mobility over time.
