Brazilian Journal of Botany , 2008, DOI: 10.1590/S0100-84042008000300009
Abstract: during the taxonomic revision of the neotropical bulbophyllum (orchidaceae) species, a new species was discovered from bom sucesso, minas gerais state, described and illustrated here as b. hatschbachianum e. c. smidt & borba. this species belongs to the neotropical section xiphizusa (rchb. f.) cogn. and posses a lip epichile completely different from the related species. it is closely to b. plumosum (barb. rodr.) cogn. due to its vegetative morphology, but has different flower size, color and lip epichile. in b. plumosum the epichile is thin, longer and wider than the hipochile. in b. hatschbachianum the epichile is fleshy, shortest than the hipochile, thin, and sharply narrower than the hipochile. the flowers of this new species is similar to the mexican b. solteroi r. gonzález, but the general morphology of the lip, trichome size and the geographical distribution clearly distinguishes apart the two species.
O gênero Bulbophyllum Thouars (Orchidaceae) na Chapada Diamantina, Bahia, Brasil

Abstract: the chapada diamantina is located in the northern region of the espinha?o range, and its main vegetation type is the "campo rupestre", but other vegetational types also occur such as gallery forests, cerrado and caatinga, and the whole region presents high endemism. bulbophyllum thouars is the largest genus of orchidaceae, with nearly 1.200 species. fifty-eight bulbophyllum species are recognized from brazil, and only five of them were until recently reported for the bahia state. in this study we present a survey of the bulbophyllum species occurring in the chapada diamantina, based on herbarium and field collections. we found 12 bulbophyllum species and one natural hybrid in the chapada diamantina, eight of which are new occurrences for the state. bulbophyllum epiphytum barb. rodr., b. laciniatum (barb. rodr.) cogn., and b. napellii lindl. are epiphytic; b. involutum borba, semir & f. barros, b. mentosum barb. rodr., b. roraimense rolfe, b. weddellii (lindl.) rchb. f., and b. ×cipoense borba & semir occur exclusively as rupicolous; and b. chloropterum rchb. f., b. cribbianum toscano, b. ipanemense hoehne, b. manarae foldats and b. plumosum (barb. rodr.) cogn. present facultative habit. bulbophyllum ipanemense is the most abundant species of the genus in the chapada diamantina, and the populations of this species in bahia present several morphological differences in relation to the populations of southeastern region. b. manarae and b. roraimense, formerly considered as endemic to venezuela, are mentioned for the first time to brazil, strengthening the hypothesis of a close relationship between the flora of that country and the chapada diamantina.

Abstract: Bulbophyllum malipoense Z.J.Liu,L.J.Chen & W.H.Rao and Bulbophyllum minor Z.J.Liu,L.J.Chen & W.H.Rao,two new orchid species from China,are described and illustrated.Both of them belong to Bulbophyllum section Biseta,and are akin to B.bisetum.Bulbophyllum malipoense differs from B.bisetum by having bilobed-tipped leaves and a glabrous lip,and B.minor differs from B.malipoense by having ellipsoid-globose pseudobulbs,ovate-elliptic leaves 1.2-2 cm long,shorter lateral calycules ca.1 mm long,and a central calycule almost entirely adnate to the connate margins of the lateral sepals.

Abstract: Aims Bulbophyllum ambrosia is an epiphytic orchid growing on rocks and trees in limestone seasonal rainforests and is commonly distributed in southern China.We found no fruit set of B.ambrosia during long-term monitoring of species diversity,reproductive phenology and pollinators of local orchid species in Green Stone Forest Park.Our objective was to determine barriers to fruit set in B.ambrosia.Methods Flowering phenology and natural fruit-set were monitored once a week for three years.Floral morphology wa...
Evidence of natural hybridization and introgression in Bulbophyllum involutum Borba, Semir & F. Barros and B. weddellii (Lindl.) Rchb. f. (Orchidaceae) in the Chapada Diamantina, Brazil, by using allozyme markers

Abstract: hybridization between b. involutum and b. weddellii (orchidaceae) has been first observed in the serra do cipó, minas gerais state, brazil, the hybrid being described as b. ×cipoense borba & semir. in this study, allozime electrophoresis was used to test the hypothesis of occurrence of hybridization between these two species, as suggested by morphological characters, in the chapada diamantina, bahia state, brazil. the lack of a diagnostic locus does not allow definite confirmation of the natural hybridization, although this hypotheses is reinforced by the absence of exclusive alleles in the putative hybrid individuals. the existence of several different genotypes points out to either population derived from multiple hybridization events or the hybrids produced offspring. homozigosity in some morphologically intermediate individuals of alelles which are exclusive to b. involutum and high genetic similarity between them reinforce the hypotheses of introgression in b. involutum, but not in b. weddellii. genetic variability observed in b. weddellii (he = 0.21) and b. involutum (he = 0.35) is high. bulbophyllum weddellii and b. involutum presented very high genetic similarity values (0.94). these species, although vegetatively similar, have been placed in different sections based on floral morphology. the results suggest that these species may be more related than previously supposed.

Pronounced Fixation, Strong Population Differentiation and Complex Population History in the Canary Islands Blue Tit Subspecies Complex  [PDF]

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0090186
Abstract: Evolutionary molecular studies of island radiations may lead to insights in the role of vicariance, founder events, population size and drift in the processes of population differentiation. We evaluate the degree of population genetic differentiation and fixation of the Canary Islands blue tit subspecies complex using microsatellite markers and aim to get insights in the population history using coalescence based methods. The Canary Island populations were strongly genetically differentiated and had reduced diversity with pronounced fixation including many private alleles. In population structure models, the relationship between the central island populations (La Gomera, Tenerife and Gran Canaria) and El Hierro was difficult to disentangle whereas the two European populations showed consistent clustering, the two eastern islands (Fuerteventura and Lanzarote) and Morocco weak clustering, and La Palma a consistent unique lineage. Coalescence based models suggested that the European mainland forms an outgroup to the Afrocanarian population, a split between the western island group (La Palma and El Hierro) and the central island group, and recent splits between the three central islands, and between the two eastern islands and Morocco, respectively. It is clear that strong genetic drift and low level of concurrent gene flow among populations have shaped complex allelic patterns of fixation and skewed frequencies over the archipelago. However, understanding the population history remains challenging; in particular, the pattern of extreme divergence with low genetic diversity and yet unique genetic material in the Canary Island system requires an explanation. A potential scenario is population contractions of a historically large and genetically variable Afrocanarian population, with vicariance and drift following in the wake. The suggestion from sequence-based analyses of a Pleistocene extinction of a substantial part of North Africa and a Pleistocene/Holocene eastward re-colonisation of western North Africa from the Canaries remains possible.
