“…There are about 2,000 species of Cactaceae across 124 genera distributed in tropical and temperate regions of the Americas (North, Central, and South America) (Rego et al 2012), with four main centers of diversity (Taylon in Oldfield 1997): the United States, Mexico, the Andean Region, and Brazil (Figure 1). However, some species of cacti are found on other continents, such as Rhipsalis baccifera ((J.M.…”

Humans have used and coexisted with cacti in arid regions of North and South America for thousands of years. Species of the family Cactaceae possess physiological adaptations to arid and semi-arid climates that have allowed them to be used as a resource throughout the year by traditional peoples. The objective of this review is to present information on the uses and management of species of Cactaceae in the various regions of the Americas. This review provides information relevant to conservation policies regarding this important resource for local populations in semi-arid regions. To fully understand how management can influence cacti conservation, a knowledge gap regarding the traditional management of cacti needs to be addressed.

Pollination biology of the endangered columnar cactus Cipocereus crassisepalus: a case of close relationship between plant and pollinator

et al. 2020

The family Cactaceae possesses considerable floral diversity and is exclusively zoophilic. Cipocereus crassisepalus is an endangered species of columnar cactus, whose floral characteristics fit the chiropterophily syndrome. This study aimed to assess the correspondence between floral traits and pollinators and whether the pollination system of C. crassisepalus is specialized, as suggested by the hypothesis of geographical dichotomy. Hand pollination treatments demonstrated that C. crassisepalus depends on cross-pollen flow mediated by pollinators to set fruit and seeds. Nocturnal film recordings, diurnal observations, analyses of pollen loads of flower visitors and visitor exclusion experiments provided strong evidence that bats are the sole pollinators of this cactus. During two flowering seasons, pollen grains of C. crassisepalus were found only on the bodies of the bat Anoura caudifer. Cipocereus crassisepalus possesses a pollination system specialized on nectar-feeding bats, which corroborates the geographical dichotomy hypothesis.

“…An insight to the cactus reproductive mechanisms is the first step towards understanding genetic structure and demographic dynamics (Pereira et al 2009) of plant species. Only 10% of the 270 Brazilian cacti have been studied from the floral and reproductive biology (Schlindwein and Wittmann 1995, Aona et al 2006, Colaço et al 2006, Lenzi and Orth 2011, Rego et al 2012, Gomes et al 2014, Martins et al 2016, Paulino‐Neto et al 2016, Martins and Freitas 2018, Rocha et al 2019). Teixeira et al (2018) inferred that Uebelmannia buiningii may be Critically Endangered (CR) because of a combination of pressure on its habitat and illegal collection negatively impacting its already small populations, added to gametophyte self‐incompatibility that leads to obligate allogamy, dependent on pollinators in order to produce seeds.…”

Uebelmannia pectinifera Buining subsp. pectinifera (Cactaceae) is an endangered species endemic to quartzitic rocks in campo rupestre vegetation of Minas Gerais state, Brazil. Understanding its reproductive biology and pollinators is needed for effective conservation planning for the species. The study took place in the Parque Nacional Sempre Vivas where 35 individuals were monitored. Analyses of floral morphology, pollen/ovule ratio, stigma receptivity and presence of osmophores were carried out, while observations of floral visitors were made and, according to their behavior, the potential pollinators were ascertained. The reproductive system of the plant was evaluated by means of manual self‐ and cross‐pollination and growth and morphology of pollen tubes were observed. The anthesis occurs by 06 a.m. and ends around 03 p.m., the flowers re‐opening for two days and finishing on the third day, being protandrous and melittophilous, offering pollen only. Two species of solitary bees (Ceratina sp. and Chilicola huberi) were observed pollinating the flowers, the female bees collecting pollen. The reproductive system is allogamic with endogamic self‐incompatibility and is served by specific pollinators. U. pectinifera subsp. pectinifera occurs in small populations, its reproduction relies on the presence of pollen‐gathering bees that also depend on the associated flora for nectar provision, highlighting the importance of maintaining its surrounding habitat in good condition.
