Abstract:
... The geographic distributions of marine fishes have been shaped by ancient vicariance and ongoing dispersal events. Some species exhibit anti‐equatorial distributions, inhabiting temperate regions on both sides of the tropics while being absent from equatorial latitudes. The perciform fish Microcanthus strigatus (the stripey) exhibits such a distribution with disjunct populations occurring in East ...

... The mitochondrial genetic diversity, distribution and invasive potential of multiple cryptic operational taxonomic units (OTUs) of the red invasive seaweed Asparagopsis were assessed by studying introduced Mediterranean and Hawaiian populations. Invasive behavior of each Asparagopsis OTU was inferred from phylogeographic reconstructions, past historical demographic dynamics, recent range expansion ...

Abstract:
... Invasive reptiles cause global ecosystem damage and are difficult to control once established. Visual detection and manual capture are time consuming and largely ineffective at eradication, particularly for cryptic species. The Jackson's chameleon (Trioceros jacksonii xantholophus), native to eastern Africa, is popular in the global pet trade and has become established in several localities, inclu ...
... Accurate estimates of the distribution and abundance of endangered species are crucial to determine their status and plan recovery options, but such estimates are often difficult to obtain for species with low detection probabilities or that occur in inaccessible habitats. The Puaiohi (Myadestes palmeri) is a cryptic species endemic to Kauaʻi, Hawai‘i, and restricted to high elevation ravines that ...
... The ambrosia beetle morphologically identified as Euwallacea fornicatus consists of several cryptic species that exhibit large differences in the DNA sequences of several nuclear and mitochondrial gene regions. Based on these differences, we suggest that there are at least three different species each with distinct phylogeography. Members of this cryptic species complex have invaded many areas out ...

Abstract:
... Both Malaysia and Indonesia have high biodiversity for a variety of organisms, including freshwater red algae. The type localities of over a dozen freshwater red algal taxa are located in Malaysia and Indonesia. These species were described prior to the advent of molecular systematics, and no molecular data were available for specimens from these two countries. Therefore, the goal of this study wa ...
Bemisia tabaci; climate; cryptic species; genetic analysis; genetic markers; genetic variation; genotyping; greenhouses; microsatellite repeats; mitochondria; phylogeography; population genetics; population structure; Hawaii
Abstract:
... The Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) cryptic species complex of whitefiies contains two species, MEAM1 and MED, that are highly invasive in supportive climates the world over. In the United States, MEAM1 occurs both in the field and in the greenhouse, but MED is only found in the greenhouse. To make inferences about the population structure of both species, and the origin and re ...
... Vis M.L., Feng J., Chiasson W.B., Xie S.-L., Stancheva R., Entwisle T.J., Chou J.-Y. and Wang W.-L. Investigation of the molecular and morphological variability in Batrachospermum arcuatum (Batrachospermales, Rhodophyta) from geographically distant locations. Phycologia 49: 545–553. DOI: 10.2216/10-04.1 Phylogeographic patterns in Batrachospermum arcuatum were investigated using the mitochondrial ...
... Nucleotide variation in cytochrome c oxidase subunit I (COI) was used to examine population structure in three invasive bryozoans: Bugula neritina (Linnaeus, 1758), Watersipora subtorquata (d’Orbigny, 1852), and W. arcuata (Banta, 1969). These species are found on ship hulls and have a short (≤2 days) larval phase. Samples were collected from 1998–2001 at multiple sites in Australia, and in Hong K ...
