“…Climber dispersal syndromes were not significantly different between the two forest types; however SDF, with a strongly synchronous leaf fall and higher canopy, did have more anemochory than did cerradão. Gentry (1991) reported a higher proportion of anemochorous climbing plant species than for trees and shrubs, a pattern confirmed here in both forest types (Assunção et al, 2014). Once climbers reach the canopy, branches of the emergent trees may facilitate dispersal of climbers with aerodynamic seeds or fruits.…”

“…This pattern was noted for tree and shrub species of the area (Assunção et al, 2014). The shared climbing species (30 %) suggest that forest fragments of the broad Cerrado phytophysiognomy may function as corridors for generalist species , in our case Smilax fluminensis, Manettia cordifolia, Mascagnia cordifolia, and Urvillea laevis, which are found in several vegetation types of Central Brazil (Udulutsch et al, 2004;Santos et al, 2009;Vargas et al, 2013).…”

“…The Southern part of the mountain range is rugged with steep hills, harboring several phytophysiognomies of varying floristic composition, which may allow interconnections between seasonal forests and other vegetation types. Previous research in the region (Ramos & Sartori, 2013;Assunção, Casagrande, & Sartori, 2014) did not include climbing species. High rates of deforestation in the mountain range contribute to a lack of information on the flora and its biogeographical affinities.…”

Abstract:In the Parana basin, the Serra de Maracaju juxtaposes the Seasonal Dry Forest and the cerradão (a phytophysiognomy of Cerrado), two distinct vegetation types that differ in canopy height, tree density, and composition of the understory. In the same way, these differences may be reflected in the composition of climbing plant species found in these two forest types. Thus, in this study we compared the climbing species in two forest fragments of Serra de Maracaju to understand: (1) Are species richness and floristic composition of climbing plants similar in cerradão and seasonal deciduous forest?, (2) What degree of floristic compositional difference exists between the two vegetation types?, (3) Do the two vegetation types differ significantly in climbing mechanisms, life forms, and dispersal syndromes represented among climbing species? For this, we established and sampled four plots per forest type over 24 months. Species were identified and each one classified, based on three discrete traits. Proportional differences were analyzed using chi-square tests. Our results showed that species richness and floristic composition of climbing plants in the cerradão and the seasonal deciduous forest were not similar. Climber species richness in cerradão was 37 while in the seasonal deciduous forest it was 31; they share only 13 species. Four families, Dioscoreaceae, Fabaceae, Malpighiaceae, and Sapindaceae, included over 60 % of the climbing species. The morphological traits most common in both forest types were herbaceous life form, apical twining mechanism, and wind dispersal. Dioscoreaceae was found to be the dominant family, but is the first time to be reported for this condition in Brazil. Bignoniaceae and Passifloraceae ocurred only in the cerradão, and Asteraceae and Combretaceae in the seasonal deciduous forest; some species were found exclusively in a type of forest. Floristic composition of the cerradão and seasonal deciduous forest fragments were substantially different, in spite of physical proximity. However, their climbing species are not statistically distinct in morphological characteristics, possibly due to uniform climatic conditions and the similarity of species because of a shared ancestry (similar families).

Epub 2017 September 01.Key words: climbing mechanism, dispersion, life form, cerradão, Dioscoreaceae.Tropical climates support climbing floras with high species richness, morphological diversity, and phylogenetic diversity. Climber species play essential roles in tropical plant communities, contributing with significant richness to tropical forests (Hergarty & Caballé, 1991;Engel, Fonseca, & Oliveira, 1998), and occurring in both evergreen and seasonal forests. Collectively, climbers show tolerance to large ranges of latitude, altitude, climate, and soil types (Gentry, 1991). At least 133 plant families include the climbing habit, which evolved independently several times; indeed almost 40 % of vascular plant families in Brazil include climbers (Schenck, ...

“…Agostini-Costa et al (2006) corroborate that the high humidity associated with high temperatures favors fungal action, which is detrimental to flowering, as loang as a humidity rates of less than 50% for prolonged periods during flowering can reduce the viability of pollen. Thus, this seems to be the most appropriate period for the flowering of A. occidentale, not only for this species but several other species of the same family (Anacardiaceae), such as A. humile, A. nanum (AGOSTINI-COSTA et al, 20006) and Astronium fraxinifolium (PIRANI et al, 2009;ASSUNÇÃO et al, 2014) thatflower during a similar period as the ones studied here.…”

Anacardium occidentale (Anacardiaceae) is a species of great economic importance for Brazil and several other countries due to its food and medicinal uses. However, studies describing its reproductive phenological cycle are scarce. For this reason, this study aimed to describe the reproductive phenology of A. occidentale in Montes Claros de Goiás, state of Goiás, Brazil. Between June 2012 and July 2015, the phenophases of flower budding, anthesis, underripe fruit and ripe fruit were recorded monthly using the Fournier scale. Data were analyzed using the Fournier index, absence/presence method, and circular statistics. The data were correlated with the average, maximum, and minimum temperatures and the precipitation of the study area. Flowering and fruiting were synchronous in the dry season, and the two events ended with the onset of rainfall, resulting in a significant negative correlation between flowering and precipitation (rs =-0.73) and a significant positive correlation between fruiting and average temperature (rs = 0.70) and between fruiting and maximum temperature (rs = 0.41). The minimum temperature influenced when anthesis (rs =-0.64) and underripe fruit (rs =-0.37) would occur. The reproductive phenological events of A. occidentale are closely related to the climatic data of the studied area. A. occidentale presents reproductive strategies for species perpetuation in the study area.

“…In Costa Rican dry forests, seasonal variation in rainfall generates seasonality in vegetation growth. Skipper butterfly (Aguna asander) caterpillars rely on leaves of Bauhinia ungulata, a shrub that produces leaves only during the rainy season (Assunção et al 2014). In the absence of Bauhinia leaves, the insects migrate uphill to colder strata where they estivate in trees and among rocks.…”

Landscapes of vertical relief, such as mountains and continental slopes, intensify ecological and climatological variation within narrow spatial windows. Seasonal vertical migrants exploit this variation during their residence in, and movements between, vertically stratified seasonal ranges. Animals in terrestrial, marine, and even human-ecological systems undergo similar patterns of seasonal vertical movements. The diversity of arenas in which vertical migration evolved lends insight to the factors promoting seasonal use of landscapes of relief. Because animals must contend with both endogenous circannual rhythms and exogenous environmental seasonality, vertical migrants may be sensitive to inconsistent change across stratified seasonal ranges under climate change. To better understand how ongoing and future climatic and environmental changes are likely to impact vertical migrants, we examine vertical migration in the context of niche tracking and niche switching. Whereas niche trackers minimize variation in realized environmental conditions throughout their seasonal movements, niche switchers undergo seasonal transitions in realized niche space. These strategies mediate the relationship between migrants and their changing environment, and can be used to forecast impacts of future change and effectively conserve systems of vertical migration. Niche tracking may be hindered by inconsistent or unpredictable environmental change along a single niche axis across strata, while niche switching may be sensitive to incongruous spatiotemporal change across factors. We suggest that climate change will affect seasonal patterns in vertical environments discontinuously across time, space, and strata, and that vertical migrants are likely to face additional anthropogenic threats that interact with environmental seasonality. Conservation of vertical migrants should prioritize the availability of, and facilitate movement between, stratified seasonal ranges.
