A reassessment of Mappia (Icacinaceae) taxonomy using environmental data
Background and Aims: Mappia (Icacinaceae) is a genus comprising four species inhabiting Mesoamerica and the Greater Antilles. In the most recent phylogenetic analysis based on morphological data, three species, representing a continental clade (Mappia longipes, M. mexicana and M. multiflora) sister...

| description | Background and Aims: Mappia (Icacinaceae) is a genus comprising four species inhabiting Mesoamerica and the Greater Antilles. In the most recent phylogenetic analysis based on morphological data, three species, representing a continental clade (Mappia longipes, M. mexicana and M. multiflora) sister to the Antillean species M. racemosa, were supported. Our aims in this study were to evaluate whether environmental data support the previous hypothesis in Mappia entities.
Methods: In this study, we use ecological niche analysis (environmental niche modeling and niche divergence/conservatism tests) and multivariate analysis of variance (MANOVA) to test the previous morphological hypothesis at species and infraspecific level.
Key results: Ecological differentiation between M. multiflora distributed from southeast Mexico to Costa Rica and M. racemosa occurring in Cuba, Jamaica, and Puerto Rico (Greater Antilles) was found, but not between the infraspecific taxa within the Antilles (M. racemosa var. brachycarpa, and M. racemosa var. racemosa).
Conclusions: Our study brings an important signal of the ecological divergence between closely related species, but with disjunct patterns of distribution. |

Antecedentes y Objetivos: Mappia (Icacinaceae) es un género de cuatro especies que habitan Mesoamérica y las Antillas Mayores. El más reciente análisis filogenético del género basado en datos morfológicos apoyó la existencia de un clado continental formado por Mappia longipes, M. mexicana y M. multiflora como grupo hermano de M. racemosa que se distribuye en las Antillas. El objetivo fue evaluar si datos ambientales soportan las hipótesis previas propuestas para las entidades de Mappia. Métodos: Se realizaron análisis de nicho ecológico (modelado de nicho ambiental y pruebas de divergencia/conservadurismo de nicho) y de varianza multivariado (MANOVA) para evaluar si existen otras líneas de evidencia que respalden la hipótesis morfológica previa a nivel de especie e infraespecífico. Resultados clave: Se encontró una diferenciación ecológica entre M. multiflora (sureste de México a Costa Rica) y M. racemosa (Cuba, Jamaica y Puerto Rico (Antillas Mayores)), pero no entre los taxones infraespecíficos de las Antillas (M. racemosa var. brachycarpa y M. racemosa var. racemosa). Conclusiones: Nuestro estudio aporta una importante señal de la divergencia ecológica entre especies cercanamente emparentadas, pero con patrones de distribución disyunta.
