Spondias tuberosa Arruda (Anacardiaceae), a threatened tree of the Brazilian Caatinga?

Abstract: Spondias tuberosa Arr., a fructiferous tree endemic to the northeast Brazilian tropical dry forest called Caatinga, accounts for numerous benefits for its ecosystem as well as for the dwellers of the Caatinga. The tree serves as feed for pollinators and dispersers as well as fodder for domestic ruminants, and is a source of additional income for local smallholders and their families. Despite its vantages, it is facing several man-made and natural threats, and it is suspected that S. tuberosa could become extin… Show more

“…(LIMA-FILHO, 2011). Apesar de seus benefícios, esta árvore enfrenta várias ameaças naturais e antrópicas que podem levar a sua extinção devido a reduzida capacidade de regeneração, o que leva à diminuição da população (MERTENS et al, 2017). O seu plantio e uso racional deve ser incentivado mesmo em áreas verdes urbanas.…”

“…Spondias tuberosa Arruda Câmara (Umbu) and Spondias sp. (umbu-caja) are fruit plants of the Anacardiaceae family, native to Northeastern Brazil (MERTENS et al, 2017), with mechanisms of survival to the water scarcity and irregular rainfall distribution that prevail in the Brazilian semi-arid region, such as leaf abscission, roots with structures called tubers or xylopodia, popularly known as 'umbu potatoes' with the function of storing water and nutrients (MITCHELL;DALY, 2015), in addition to efficient control of leaf transpiration AIDAR, 2016).…”

“…tuberosa is indigenous to the Caatinga biome, which is found only in Brazil; this biome covers 70% of the Northeastern region of Brazil and 11% of the Brazilian territory (LIMA; SILVA; OLIVEIRA, 2018) and is characterized by long drought periods, with average rainfall of 600 mm year -1 concentrated between February and May (SOUZA; MENEZES; ARTIGAS, 2015). S. tuberosa is a perennial arboreal species of the Anacardiaceae family; it reaches heights of approximately 7 m and canopy diameter of approximately 12 m. This is a xerophilous, deciduous plant that is adapted to hot environments and soils with different fertility levels and has agricultural potential, since it grows well under temperatures between 12 ºC and 38 ºC and insolation periods of 2,000 to 3,000 hours year -1 (MERTENS et al, 2016).…”
