Paraphyly and Endemic Genera of Oceanic Islands: Implications for Conservation¹

Amphitropical disjunctions in New World Menthinae: Three Pliocene dispersals to South America following late Miocene dispersal to North America from the Old World

“…Th e second is the ditypic Cuminia , endemic to Robinson Crusoe Island, one of the Juan Fernández Islands off the coast of Chile. Little is known about its relationships, timing of arrival into the Juan Fernández Island archipelago, and continental source of propagules ( Bernardello et al, 2006 ;Stuessy et al, 2014 ). Bernardello et al (2006) simply indicated that Cuminia likely arrived from the "pantropics" via nutlets ingested internally by birds.…”

Diversidad y distribución de los endemismos de Asteraceae (Compositae) en la Flora del Ecuador

“…f., decisión que fue aceptado por Cronquist (1971), excluida por Gardner (1979) por ser un nombre dudoso y rechazada por Wagner & Robinson (2001) Panero et al (1999) esta especie es hermana del género Sphaneticola O. Hoffm. de la zona costera pantropical de Mesoamérica y del norte de América del Sur (Stuessy et al, 2014), probablemente su ancestro proceda de esta región de América Tropical (Panero et al, 1999).…”

“…Las filogenias moleculares realizadas por Blöch et al (2009) y Stuessy et al (2011) muestran que el género Lecocarpus está incluido dentro de la variación del género Melampodium L. (parafilético), cuyo origen pudo ocurrir a partir de la rápida divergencia de poblaciones ancestrales de Acanthospermum a consecuencia de las condiciones ambientales imperantes en las islas (Stuessy et al, 2014).…”

Notes on Australian species of Salsola (Chenopodiaceae) and validation of Salsola sabrinae, nom. et stat. nov.

“…Kadereit et al, 2014;Piirainen et al, 2017;Mosyakin, Iamonico, 2017, and references therein). Phylogenybased reconstructed migration patterns of many other taxa occurring in remote areas of the Southern Hemisphere also indicate that long-distance and/or step-stone dispersal events followed by fast evolutionary radiations played an important role in shaping the current patterns of geographical disjunctions and centers of diversity in vascular plants (see examples and case studies in Cain et al, 2000;Winkworth et al, 2002Winkworth et al, , 2015Mosyakin et al, 2007;Stuessy et al, 2014;Mosyakin, Iamonico, 2017;Murphy, Crayn, 2017;Ebach, 2017, and references therein).…”
