Leucothoe eltoni sp. n., a new species of commensal leucothoid amphipod from coral reefs in Raja Ampat, Indonesia (Crustacea, Amphipoda).
ZooKeys, 2015Co-Authors: James Darwin ThomasAbstract:A new species of leucothoid amphipod, Leucothoe eltoni sp. n., is described from coral reefs in Raja Ampat, Indonesia where it inhabits the branchial chambers of solitary tunicates. With an inflated first gnathopod superficially resembling the genus ParaLeucothoe, this new species has a two-articulate maxilla 1 palp characteristic of the genus Leucothoe. While described from coral reef environments in tropical Indonesia and the Philippines, it is an established invasive species in the Hawaiian Islands. The most likely mode of introduction was a US Navy dry dock transported to Pearl Harbor in 1992 from Subic Bay, Philippines.

New Species and Host Associations of Commensal Leucothoid Amphipods from Coral Reefs in Florida and Belize (Crustacea:Amphipoda)
Zootaxa, 2007Co-Authors: James Darwin Thomas, Kristine N. KlebbaAbstract:Six new amphipod species in the genus Leucothoe from the tropical western Atlantic Ocean are described and illustrated. Extensive field collecting and specialized underwater collecting techniques have documented 43 new invertebrate host records for these new taxa. Four of these new species inhabit interior canals of sponges; Leucothoe barana n.sp., Leucothoe garifunae n.sp., Leucothoe saron n.sp., and Leucothoe ubouhu n.sp. A remarkable new species, Leucothoe flammosa n.sp., nestles in the gills of seven species of bivalve mollusks. A single species, Leucothoe wuriti n.sp., appears restricted to the branchial chamber of two species of solitary ascidians. Detailed illustrations and scanning electron microscopy enables comparison of ultrastructure details. More precise taxonomic character morphologies are also presented thus allowing improved taxonomic precision within the family Leucothoidae.

Genetic connectivity in the Florida reef system: comparative phylogeography of commensal invertebrates with contrasting reproductive strategies.
Molecular ecology, 2006Co-Authors: Vincent P. Richards, James Darwin Thomas, Michael J. Stanhope, Mahmood S. ShivjiAbstract:Effective spatial management of coral reefs including design of marine protected areas requires an understanding of interpopulation genetic connectivity. We assessed gene flow along 355 km of the Florida reef system and between Florida and Belize in three commensal invertebrates occupying the same host sponge ( Callyspongia vaginalis ) but displaying contrasting reproductive dispersal strategies: the broadcast-spawning brittle star Ophiothrix lineata and two brooding amphipods Leucothoe kensleyi and Leucothoe ashleyae. Multiple analytical approaches to sequence variation in the mitochondrial COI gene demonstrated a high degree of overall connectivity for all three species along the Florida reef system. Ophiothrix lineata showed significant genetic structuring between Florida and Belize, and a pattern of isolation by distance but no significant genetic structuring along the Florida coastline. Bayesian estimates of migration detected a strong southerly dispersal bias for O. lineata along the Florida reef system, contrary to the general assumption of northerly gene flow in this region based on the direction of the Florida Current. Both amphipods, despite direct development, also showed high gene flow along the Florida reef system. Multiple inferences of long-distance dispersal from a nested clade analysis support the hypothesis that amphipod transport, possibly in detached sponge fragments, could generate the high levels of overall gene flow observed. However, this transport mechanism appears much less effective across deep water as connectivity between Florida and Belize (1072 km) is highly restricted.

A taxonomic revision of Leucothoë (Ericaceae; Tribe Gaultherieae)
Brittonia, 2013Co-Authors: Walter S. Judd, Katherine Waselkov, Norman C. Melvin, Kathleen A. KronAbstract:Leucothoë is here defined as a genus of five species ( L. axillaris, L. fontanesiana, L. griffithiana, L. keiskei , and L. davisiae ), occurring in eastern Asia and western and eastern North America. Generic autapomorphies include autumn-formed inflorescences with meiosis occurring in the autumn. Members of the Leucothoë clade, which are evergreen, are sister to the deciduous Eubotryoides grayana , sharing the apomorphies of winged seeds with a distinctly protuberant hilum, the former of which is homoplasious. Leucothoë axillaris and L. fontanesiana , both of eastern North America, form a closely related species pair, as do the eastern Asian L. griffithiana and L. keiskei . Leucothoë davisiae , occurring in western North America, is likely sister to the remaining species, and it differs in having erect branches and inflorescences, minutely bullate capsules, and in the lack of awns on the anthers. Species descriptions, nomenclatural information, specimen citations, and eco-geographical characterizations for these five species are presented, along with an identification key.

The Phylogeny of Leucothoë s. l. (Ericaceae: Vaccinioideae) Based on Morphological and Molecular (ndhF, matK, and nrITS) Data
Systematic Botany, 2010Co-Authors: Catherine M. Bush, Walter S. Judd, Louis Frazier, Kathleen A. KronAbstract:Abstract Leucothoe s. l. has been split into as many as three genera in current taxonomic work involving morphological data. In this paper, phylogenetic relationships within Leucothoe s. l. were examined using DNA sequence data from matK, ndhF, nrITS, and morphological characters. The total combined data indicate that Leucothoe s. l. species are distributed between two clades. Leucothoe racemosa and L. recurva are strongly supported as being sister taxa and are in turn sister to Chamaedaphne calyculata. These two Leucothoe species are deciduous and they exhibit “L. racemosa”-type autumn inflorescences (as does Chamaedaphne). The other six Leucothoe s. l. species (L. axillaris, L. davisiae, L. fontanesiana, L. grayana, L. griffithiana, and L. keiskei) form a strongly supported clade. Leucothoe grayana, a morphologically distinctive taxon, is sister to the other five species in this latter clade. Based on these data, it is proposed that Leucothoe s. l. should be divided into three genera: Eubotryoides (E. g...

Phylogenetic analyses of Andromedeae (Ericaceae subfam. Vaccinioideae).
American journal of botany, 1999Co-Authors: Kathleen A. Kron, Walter S. Judd, Darren M. CraynAbstract:Phylogenetic relationships within the Andromedeae and closely related taxa were investigated by means of cladistic analyses based on phenotypic (morphology, anatomy, chromosome number, and secondary chemistry) and molecular (rbcL and matK nucleotide sequences) characters. An analysis based on combined molecular and phenotypic characters indicates that the tribe is composed of two major clades—the Gaultheria group (incl. Andromeda, Chamaedaphne, Diplycosia, Gaultheria, Leucothoe ¨, Pernettya, Tepuia,and Zenobia) and the Lyonia group (incl. Agarista, Craibiodendron, Lyonia, and Pieris). Andromedeae are shown to be paraphyletic in all analyses because the Vaccinieae link with some or all of the genera of the Gaultheria group. Oxydendrum is sister to the clade containing the Vaccinieae, Gaultheria group, and Lyonia group. The monophyly of Agarista, Lyonia, Pieris, and Gaultheria (incl. Pernettya) is supported, while that of Leucothoe ¨ is problematic. The close relationship of Andromeda and Zenobia is novel and was strongly supported in the molecular (but not morphological) analyses. Diplycosia, Tepuia, Gaultheria, and Pernettya form a well-supported clade, which can be diagnosed by the presence of fleshy calyx lobes and methyl salicylate. Recognition of Andromedeae is not reflective of our understanding of geneological relationships and should be abandoned; the Lyonia group is formally recognized at the tribal level.
