A New Species of Jatropha (euphorbiaceae) from Nicaragua'
When Jatropha costaricensis Webster & Poveda was described from Guanacaste, Costa Rica, some years ago (Webster & Poveda, 1978), it was predicted that other xeric relict taxa might be discovered elsewhere in Central America. Recent botanical exploration in Nicaragua has disclosed not only a number of new populations of Jatropha podagrica Hook. in rocky areas in Dept. Esteli, but also on basalti...
متن کاملPollination ecology and circadian patterns of inflorescence opening of the Madagascan climber Dalechampia aff. bernieri (Euphorbiaceae)
Floral morphology often directly influences interactions with pollinators, but less is known about the role of extrafloral structures. We studied the relationship between bract motility, floral structural specialization and pollination in Dalechampia aff. bernieri, an endemic Madagascan species with floral structures indicating specialized buzz-pollination.Wemeasured circadian bract angles in 4...
متن کاملDevelopment of microsatellite markers for the neotropical vine Dalechampia scandens (Euphorbiaceae)1
UNLABELLED PREMISE OF THE STUDY Microsatellite markers were developed to assess polymorphism and level of genetic diversity in four Mexican populations of the neotropical vine Dalechampia scandens (Euphorbiaceae). • METHODS AND RESULTS Thirty-seven microsatellite markers representing bi-, tri-, tetra-, and pentanucleotide microsatellite repeats were developed. In total, 166 alleles were id...
متن کاملEffects of crossing distance on offspring fitness and developmental stability in Dalechampia scandens (Euphorbiaceae).
Crosses between genetically close and distant populations of Dalechampia scandens (Euphorbiaceae) were made to test whether the responses of various fitness components and measurements of developmental stability were affected by the outcrossing distance (level of outbreeding). Two fecundity traits, seed set and seed mass, decreased consistently with increasing level of outbreeding, and hybrids ...
متن کاملSignal honesty and cost of pollinator rewards in Dalechampia scandens (Euphorbiaceae).
BACKGROUND AND AIMS Most species of Dalechampia vines (Euphorbiaceae) attract bee pollinators with terpenoid resins secreted by a gland-like structure in the inflorescence. In some species, pollinating bees appear to preferentially visit inflorescences (blossoms) with large resin-producing glands, whereas in other species bees preferentially visit blossoms with large involucral bracts. In this ...
