Byrsonima is in the Byrsonima clade; its two sister genera, Blepharandra and Diacidia, are wholly South American, as is the Acmanthera clade, sister to the Byrsonima clade (Davis & Anderson, 2010).
Clade I comprised populations of Luza and Sfax while Clade II included the population of Oued Hamdoun with a very little overlapping (specimen number 17 from Luza; see Table I).
One-tailed t-test was used to examine the following null hypotheses: first, that the temporal gap calculated for each conflicting clade is not significantly longer than the mean temporal gap of all other wellsupported clades; second, that the retention index (RI) of the MPT derived from the data sets in which suspected MCs were reset to missing values was not significantly higher than the mean value of this index from the MPTs derived from randomly modified data sets.
One could regard the acridines within clade E as "peg-less gomphocerines"-a possibility, given Otte's (1981) statement concerning the relative ease with which stridulatory pegs can be lost over evolutionary time.
gentili specimens analysed grouped together in a clade containing specimens collected in the centre of the species' known range.
The macaques were then exposed to virus of a different clade.
We calculated clade credibility values from 4000 trees by sampling every 1000th tree from two runs of 5,000,000 trees after discarding the first 3001 sampled trees of each run.
Also, to protect the core photosynthetic complexes from excess light damage, we found that clade A Symbiodinium very rapidly undergoes disorganization of photosynthetic antenna pigment complexes.
dagger] Chanoides macropoma, [dagger] Clupavus maroccanus, [dagger] Santanichthys diasii, [dagger] Lusitanichthys characiformis and [dagger] Sorbininardus apuliensis were chosen for a major, precise reason: authors such as Gayet (1981, 1985, 1986), Taverne (1977a, 1995, 1999) and Filleul & Maisey (2004) have argued that these are particularly 'problematic' fossil taxa that, if included in an explicit cladistic analysis together with other ostariophysan and non-ostariophysan taxa, could well show that the four extant otophysan orders, and possibly the clade Ostariophysi, as currently recognized, do not form monophyletic groups.
By accepting a new genus Magallana [type species Crassostrea gigas (Thunberg, 1793)] for a clade of Pacific Crassostrea, and by rejecting the genus Talonostrea (Li and Qi, 1994) [type species Talonostrea talonata (Li and Qi, 1994)] for the Pacific sister clade Magallana, WoRMS has effectively rendered the (Atlantic) genus Crassostrea paraphyletic.
Because recent reports have documented an increase in the number of C1-M27 clade isolates in Japan and France, we investigated [bla.
