“…The intolerance of palms to low temperatures and their latitudinal range limitation are directly evidenced in the horticultural literature (Henderson et al ., 1995;Jones, 1995;Francko, 2003). However, naturalization of palm species beyond their native ranges (Henderson et al ., 1995;Landry & Reese, 1996;Walther, 2000;Sunderland & Morakinyo, 2002;Svenning, 2002) and known regional extinctions in the past (Uhl & Dransfield, 1987;Rull, 1998) suggest that current diversity patterns may also reflect history. Furthermore, Bachman et al .…”

AimTo determine the main factors that control the distribution of palm species richness across the Americas, to understand the relative importance of climatic and other environmental factors vs. spatial variables (as substitutes for nonenvironmental factors such as history), and to evaluate how robust the patterns found are to changes in spatial scale.Location Tropical and subtropical America (34 ° N − 34 ° S; 33 ° W − 120 ° W). MethodsWe provide a GIS-based analysis of spatial variation in species richness at 10 grain sizes (1 °− 10 ° square grid cells). We use multiple regressions and variation partitioning to test patterns of species richness in relation to five environmental descriptors [mean annual temperature ( ° C), mean annual precipitation (mm year − 1 ), number of wet days year − 1 , topographical range (maximum-minimum elevation), number of vegetation types] and nine spatial variables (the terms of a cubic trendsurface polynomial). ResultsWe observe peaks in palm species richness in southern Mesoamerica, the Chocó area, western and eastern Amazon basin, and east Andean slopes, and a strong latitudinal richness gradient even within the tropical zone. Pure environmental and pure spatial variation components are of equal magnitude through all spatial scales analysed. Water-related variables such as annual rainfall and number of wet days are the main richness predictors. Spatial variables, notably latitude squared are also important, whereas temperature-and habitat-related variables are relatively unimportant.Main conclusions Our analysis suggests that in the Americas, palm species richness at spatial scales from 1 ° to 10 ° is most strongly controlled by water availability, although unknown broad-scale factors, perhaps soil, historical processes or geometric constraints, are also important.

“…Conservation status:-Least concern (LC). Notes:-Notwithstanding the long history of botanical fieldwork in the Upper Guinea forests of West Africa and despite their economic importance (Falconer 1992, Oteng-Amoako and Obiri-Darko 2001, Sunderland et al 2005) the rattan palms of the region were, until recently, particularly under-represented in herbaria. Three species of Eremospatha were previously recorded from the region; E. macrocarpa, E. laurentii and a third taxon, comprising a few incomplete voucher specimens which were frequently assigned to E. hookeri.…”

The rattans of Africa are represented by the endemic palm (Arecaceae) genera Laccosperma, Eremospatha and Oncocalamus, as well as by a single species of the otherwise Asian genus Calamus. These climbing palms occur in a wide range of ecological conditions within the lowland tropical forests of the continent and, throughout their range, play a significant role in the forest economy of the region through the utilisation of their stems, or cane. Despite this economic importance, until recently the taxonomy of this group has been unclear. Based on recent fieldwork as well as thorough examination of herbarium records, a taxonomic treatment of all African rattans is presented. This paper recognises 22 species in the four genera, including four recently described species.

“…Also, in Africa and Ghana, rattan products’ trading dates to the colonial through the two world wars eras and generating incomes for countries like Cameroon (US$50,000 in furniture trading in 1929 – Sunderland 2001). Although reports indicate that there is very limited and unpublished data on current rattan exports from African nations (Oteng-Amoako and Obiri-Darko 2001), Sunderland (2001) reports rattan products exports valuing some US$159,555 by 38 enterprises from Ghana in the 1990s. Recent developments have even revealed that rattan is medically being employed for bone regeneration/work in advanced nations and it is working effectively (Caldecott 1988; Kaam et al 2021).…”

Business success levels can be impeded by constraints. This study assessed the perception of successes and constraints in the rattan and cane furniture industry in Ghana. From 250 questionnaires distributed, 200 (80%) were retrieved for analysis at a 95% confidence level. Internal consistencies of questionnaire items for the 12 measures of successes and 22 measures of constraints were Cronbach Alpha 0.789 and 0.862, respectively. The results indicated greater success in the business with all items recording significant (P = 0.001) averages of 3.22-3.95 indicating moderate to very high success with increased income ranking highest. On average, many of the 22 constraint items were rated either moderately high or very high with a lack of financial and technical support being prominent and obtaining 83% to 100% affirmations. Frantic engagement efforts with government and nongovernmental agencies are needed towards overcoming or reducing the constraints to enhance success levels towards individual and national growth and development.
