“…Although general patterns in fruit phenology are often similar regardless of the methodology used (Zhang and Wang 1995;Stevenson et al 1998), surveys relying on fruitfall generally show a 1 month lag when compared to fruit production estimates based on inspections of individual crowns (Zhang and Wang 1995;Wallace and Painter 2002) and our samples may have underestimated the onset of fruit production in the crown. Moreover, as the end of fruitfall periods was determined by crown inspections rather than fruits on the ground, the fruiting period of all stems may have been systematically underestimated by as long as 1 month.…”

“…However, these results do provide evidence of a strong association between fruit production and a sharply demarcated dry season (cf. Terborgh 1983;Peres 1994), contrasting with other tropical forests where rainfall is considered to be a poor predictor of seasonal fruit production (Putz 1979;Chapman et al 1999a;Wallace and Painter 2002). Although fruiting patterns were most clearly marked among taxa bearing fleshy fruits ( Figure 5), which may require high moisture levels for fruit production (Lieberman 1982;Rathke and Lacey 1994), other types of fruit showed similar seasonal trends.…”

Wildfires are an increasing threat to tropical rainforests, yet little is known about their effects on fruit production and forest wildlife. We examined the effects of both single and recurrent wildfires on fruit production and large vertebrate abundance in a central Amazonian terra firme forest for 3 years following a large fire event. The estimated mortality of 42 and 74% of stems ‡10 cm in once-and twice-burnt forest led to a substantial loss of fruiting tree basal area (29 and 62% were lost in once-and twice-burnt forest, respectively) and crown coverage of fruiting woody lianas (89 and 97% were lost in once-and twice-burnt forest, respectively). Some important tree families producing fleshy fruits were less abundant than expected in once-and twice-burnt forest, suggesting that tree mortality was non-random in terms of species composition. Asynchronous fruit production was affected, and burnt forest transects sustained a much lower fruiting basal area, and fewer fruiting species during the dry season period of fruit scarcity. The number of fruiting trees in once-and twice-burnt forest was higher than the number predicted from actual levels of tree mortality recorded in each fire disturbance treatment, suggesting some surviving trees which may have benefited from higher irradiance levels and lower competition for resources. Many large frugivores and other vertebrate species declined in response to single fires, and most primary forest specialists were extirpated from twice-burnt forest, which sustained a higher number of species associated with second growth and other disturbed habitats.

“…The number of plant species with fruits suitable for mammal consumption in a Yungas Montane forest (~1500 m) peaks during the wet season (i.e. from December to April; Roldán and Larrea 2003), which is also common in other types of Neotropical forests (Leigh and Windsor 1985;Justiniano and Fredericksen 2000;Wallace and Painter 2002). Subsequent studies should evaluate whether habitat selection changes seasonally according to the availability of fruits.…”

Home range and habitat use by pacas in a montane tropical forest in Bolivia

2017

We studied the home range and habitat use of paca (Cuniculus paca) in a rural agricultural community in the Alto Beni region, in La Paz department, Bolivia, where game meat is the main source of protein for a large portion of local inhabitants. We captured and radio collared five individual paca (4 females and 1 male), which were followed for six months in 2012 to estimate home range of the individuals and assess their habitat use and selection. The total mean home range (95% Minimum Convex Polygon) was 2.26 ha (SD = 0.80), and ranged from 1.5 to 2.96 ha. The mean female home range (2.04 ha) was smaller than the male´s (2.95 ha). Pacas used two (crops and fallows) of the three available habitats (secondary forest patches), and appeared to positively select crops over the other two. The importance of crops may be linked to the type of agriculture conducted in the area (i.e. mainly cacao in agroforestry systems), which may offer more food and shelter for pacas. Given that, the importance of habitats may change seasonally; this topic should be examined in future studies. Our results suggest that agroforestry systems may be important for the species since they offer a variety of food resources throughout the year. KEYWORDS: space use, radiotelemetry, Alto Beni, cacao, agroforestry Ámbito de hogar y uso de hábitat del jochi pintado en un bosque montano tropical de Bolivia RESUMENHemos estudiado el ámbito de hogar y uso de hábitat del jochi pintado (Cuniculus paca) en una comunidad de Alto Beni en el Norte de La Paz-Bolivia, donde la carne obtenida por cacería es, como en muchas regiones de la Amazonia, una fuente principal de proteína para muchas poblaciones indígenas y campesinas. Hemos capturado y seguido con radio-collar a cinco individuos (4 hembras y 1 macho) por seis meses en 2012. El ámbito de hogar promedio de los individuos fue de 2,26 ha (ds=0,80), usando el estimador Mínimo Polígono Convexo (MPC al 95%) y los valores se encuentran entre 1,5 a 2,96 ha. El ámbito de hogar promedio de las hembras fue más pequeño (2,04 ha) que del macho (2,95 ha). Los jochis estudiados usaron 2 (cultivos y barbechos) de los 3 hábitats disponibles (parches de bosque secundario), aunque los cultivos parecen ser seleccionados positivamente respecto a los otros dos. La importancia de los cultivos podría estar ligada al tipo de cultivo que se realiza en la zona (sistemas agroforestales), que podrían estar ofreciendo mejores condiciones para ser usados por los jochis. Adicionalmente, la importancia de los hábitats podría cambiar de acuerdo a la época del año, lo cual podría ser abordado en siguientes estudios. Este trabajo es el primero en dar detalles sobre la ecología de C. paca en vida silvestre en Bolivia; sin embargo sería necesario contar con más individuos para tener más detalle sobre la ecología espacial de esta especie. PALABRAS CLAVE: uso de hábitat, radiotelemetría, Alto Beni, cacao, agroforestería

“…It seems reasonable to assume that the availability of groundwater in these environments means that water is not a limiting factor, and that these populations of M. flexuosa do not depend on the increased precipitation of the rainy season to reproduce. In these environments, the maturation and fall of fruits during the dry season may be advantageous to the palm, given the increased possibility of seed germination during the subsequent rainy season, when conditions will be ideal for the germination of the seeds of a wide variety of plants (Felfili et al, 1999;Khorsand Rosa et al, 2013), in addition to an increased probability of dispersal by frugivores, given that the fruits of M. flexuosa represent a key resource during the dry season, when most other resources are relatively scarce, provoking an increase in intra-and inter-specific competition (Steven et al, 1987;Wallace and Painter, 2002;Cabrera and Wallace, 2007).…”

Reproductive phenology of Mauritia flexuosa L. (Arecaceae) in a coastal restinga environment in northeastern Brazil

et al. 2017

The buriti, Mauritia flexuosa, is the most common palm in Brazil, where it has considerable ecological and economic importance. However, few data are available on the phenology of the species, mainly in coastal restinga ecosystems. The present study monitored the reproductive phenology of M. flexuosa in the restinga of Barreirinhas, in the Brazilian Northeast, and investigated the relationship between phenophases and climatic variables. The presence/absence of flowers and fruits was recorded monthly in 25 individuals of each sex between August, 2009, and October, 2012. There was no difference in the phenology of male and female specimens, with flowering and fruiting occurring exclusively in the dry season. We believe that the specific abiotic characteristics of the study environment, such as the intense sunlight and availability of water in the soil, contribute to the reproductive success of M. flexuosa in the dry season, with consequent germination and establishment of seedlings occurring during the subsequent rainy season.Keywords: buriti, ecology, Maranhão, palm tree.
