BackgroundPolytene chromosome banding patterns have long been used by Drosophila evolutionists to infer degree of relatedness among taxa. Recently, nucleotide sequences have preempted this traditional method. We place the classical Drosophila evolutionary biology tools of polytene chromosome inversion analysis in a phylogenetic context and assess their utility in comparison to nucleotide sequences.ResultsA simultaneous analysis framework was used to examine the congruence of the chromosomal inversion data with more recent DNA sequence data in four Drosophila species groups - the melanogaster, virilis, repleta, and picture wing. Inversions and nucleotides were highly congruent with one another based on incongruence length difference and partitioned Bremer support values. Inversion phylogenies were less resolved because of fewer numbers of characters. Partitioned Bremer supports, corrected for the number of characters in each matrix, were higher for inversion matrices.ConclusionsPolytene chromosome data are highly congruent with DNA sequence data and, when placed in a simultaneous analysis framework, are shown to be more information rich than nucleotide data.

A study was done on the genetic, morphological and behavioral characteristics of the rare Hawaiian Drosophila silvestris. Results from mating asymmetries showed that the northern Hawaiian species are ancestors of species found in the southern part of the island. A mitochondrial DNA (mtDNA) restriction site analysis further showed that the behavioral data was consistent with the mtDNA phylogeny.

Drosophilidae -- Genetic aspects ,Biology -- Identification and classification ,Biological sciences - Abstract
Seven genera of the family Drosophilidae were studied for comparison of molecular and morphological data sets. This particular family was chosen because of the advanced stage of morphological analysis and the steadily increasing molecular systematics of the group. Furthermore, the molecular, genetic and developmental status of Drosophila melanogaster is far advanced and any developmental analysis can be applied to all members of Drosophilidae. It was therefore concluded that a study of the molecular and genetic basis of morphology and development in Drosophila will give valid data for the understanding of homoplasy in systematics,

Life Sciences (General) - Abstract
Whether the serial features found in some molluscs are ancestral or derived is considered controversial. Here, in situ hybridization and antibody studies show iterated engrailed-gene expression in transverse rows of ectodermal cells bounding plate field development and spicule formation in the chiton, Lepidochitona cavema, as well as in cells surrounding the valves and in the early development of the shell hinge in the clam, Transennella tantilla. Ectodermal expression of engrailed is associated with skeletogenesis across a range of bilaterian phyla, suggesting a single evolutionary origin of invertebrate skeletons. The shared ancestry of bilaterian-invertebrate skeletons may help explain the sudden appearance of shelly fossils in the Cambrian. Our interpretation departs from the consideration of canonical metameres or segments as units of evolutionary analysis. In this interpretation, the shared ancestry of engrailed-gene function in the terminal/posterior addition of serially repeated elements during development explains the iterative expression of engrailed genes in a range of metazoan body plans.

Limited data exists on the interrelationships between physical activity (PA), sedentary behaviors and sleep concerning cardiometabolic risk factors in aged adults at high cardiovascular disease risk. Our aim was to examine independent and joint associations between time spent in leisure-time PA, sedentary behaviors and sleep on the prevalence of obesity, type 2 diabetes (T2D) and components of the metabolic syndrome (MetS) in Mediterranean individuals at high cardiovascular risk. Cross-sectional analyses were performed on baseline data from 5776 Spanish adults (aged 55-75y in men; 60-75y in women) with overweight/ obesity and MetS, from October 2013 to October 2016, in the PREDIMED-PLUS trial. Employing multivariable-adjusted Cox regression with robust variance and constant time (given the cross-sectional design), higher prevalence of obesity, T2D and abdominal obesity as component of the MetS were associated with greater time in TV-viewing (Relative Risk, RR: 1.02, 95%CI: 1.01, 1.03; RR:1.04, 95%CI: 1.02, 1.06 and RR: 1.01 95%CI: 1.00, 1.02; respectively, all P < .01). Conversely, greater time in moderate-vigorous PA (MVPA) was associated with lower prevalence of obesity, T2D, abdominal obesity and low HDL-cholesterol (RR: 0.95, 95%CI: 0.93, 0.97; RR: 0.94, 95%CI: 0.89, 0.99; RR: 0.97, 95%CI: 0.96, 0.98; and RR: 0.95, 95%CI: 0.91, 0.99, respectively, all P < .05). For these outcomes, theoretically substituting 1-h/day of MVPA for 1-h/day TV-viewing was also significantly associated with lower prevalence (RR 0.91 to 0.97, all P < .05). Similar lower RR in these outcomes was observed when substituting 1-h/day of MVPA for 1-h/day of sleeping. Longer time watching TV and not meeting MVPA recommendations were jointly associated with higher RR of the prevalence of o

A comprehensive new meta-analysis provides strong evidence that dispels the influential nagging doubt in the minds of conservation geneticists, first raised in the 1980s period that genetic considerations might be irrelevant to the conservation of species on the brink. Conservation genetics has now survived three major challenges to its utility for helping to make conservation management decisions.

Scaptomyza (Titanochaeta) Diagnosis. Titanochaeta was erected by Knab (1914) as a genus of endemic Hawaiian Drosophilidae. Hardy (1965) suggested that this genus actually should be considered a subgenus of Scaptomyza based on a variety of morphological characters including conspicuous surstyli which project well beyond the margins of the ninth tergite (Fig. 3), lack of ventral rays on the arista, and a short head which is approximately two times higher than long. We are placing the eleven known species of Titanochaeta, all of which are parasitic on spider egg sacs, in a subgenus of Scaptomyza. Chaetotaxy is an important synapomorphy of the subgenus Titanochaeta. These species have eight rows of acrostichal setulae, a character not seen in the other species of Scaptomyza. Furthermore, the setae on the head and thorax are very strong, the vertical setae are often longer than the head is wide. The shape of the head is also characteristic. It is equal to or narrower than the thorax in width, with a distinctly oblique, slanted front which is often more than two times longer than the lower margin of the head. The genae are straight sided and indented along the anterior eye margin. Finally, the ovipositor of most taxa is long and needle��like, probably due to the parasitic lifestyle of these taxa. Discussion. The new subgeneric status of Titanochaeta in Scaptomyza requires that we propose new replacement names for T. evexa, T. kauaiensis, and T. silvicola because those specific epithets are preoccupied in the genus Scaptomyza. We propose: Scaptomyza neoevexa O���Grady et al., new replacement name for Titanochaeta evexa (Hardy, 1965) (preoccupied by Scaptomyza evexa Hardy, 1965), Scaptomyza neokauaiensis O���Grady et al., new replacement name, for Titanochaeta kauaiensis (Hardy, 1965) (preoccupied by Scaptomyza kauaiensis Hackman, 1959), and Scaptomyza neosilvicola O���Grady et al., new replacement name, for Titanochaeta silvicola (Hardy, 1965) (preoccupied by Scaptomyza silvicola Hardy, 1965).

(Titanochaeta) sweyzei (Wirth), comb. nov. from Kaua���i, Maui, and O���ahu, and S. (Titanochaeta) vittigera (Hardy), comb. nov. from Kaua���i (Nishida, 2002). Discussion. The species in this group are infrequently collected and poorly understood taxonomically. The fact that a number of species in the subgenus Titanochaeta are present on multiple, non��adjacent islands suggests that they are either better at dispersing or have a lower rate of speciation than other endemic Hawaiian groups. It also might indicate that there are additional cryptic species remaining to be described in this group. KEY TO SPECIES OF THE SUBGENUS Titanochaeta Knab 17.

Scaptomyzetta Hendel, 1928: 290 (incorrect original spelling of Scaptomyzella). Grimshawomyia Hardy, 1965: 535. Type species: Drosophila perkinsi Grimshaw, 1901, by original designation. Syn. nov. Engiscaptomyza Kaneshiro, 1969: 80 (as subgenus of Drosophila). Type species: Drosophila crassifemur Grimshaw, 1901, by original designation. Syn. nov. Diagnosis. Scaptomyza is a cosmopolitan genus that currently contains about 15 subgenera (Wheeler 1981, 1986), some of which have been designated as separate genera at one time or another (Frey 1954; Hackman 1959, 1982; Malloch 1934). The traditional definition of Scaptomyza includes taxa with two to four rows of acrostichal setulae, two pairs of postsutural dorsocentral setae (and sometimes with a single set of presutural dorsocentrals as well), the third costal section 2.5 times longer than the fourth, and the head distinctly longer than high (Hardy 1965). However, a rather large radiation of about 150 described species present in the Hawaiian Archipelago, has broadened this definition somewhat, mainly because of atypical characters possessed by some of these taxa (Hackman 1959, 1962, 1982). For example, many members of the subgenus Elmomyza have six rows of acrostichal setulae, suggesting that this character may be quite variable within Scaptomyza. Therefore, having either two or four rows of acrostichals is not a good synapomorphy for the genus Scaptomyza, although it may be useful at delimiting some subgenera. Perhaps the best character defining all Scaptomyza is the presence of well developed, exposed surstyli and enlarged lobes on either the epandrium (ninth tergite), cerci, or both. These morphologies are also characteristic of the genera Grimshawomyia and Titanochaeta, as well as the subgenus Engiscaptomyza. An additional character, found in females of most species, is a weakly developed, fleshy, non��dentate ovipositor. Titanochaeta is atypical in this character as females of this group have a slender, sharply pointed, stylet��like ovipositor, a character that may be an adaptation to a lifestyle as a spider egg sac predator. Methods. We have examined the types, as well as large series of other material, from all species placed in Titanochaeta, Engiscaptomyza, and Grimshawomyia (Table 1). We also have examined material from most recognized subgenera of the genus Scaptomyza. Based on this work, we selected a number of taxa placed in the genus Scaptomyza, as well as representatives of Drosophila (Engiscaptomyza), Grimshawomyia, and Titanochaeta thought to be closely related to this genus, for use in the current molecular and morphological analyses. Over 3.3 kilobase pairs of nucleotide sequence from five genes (16S, Adh, COI, COII, Gpdh) were examined in about 120 drosophilid species using a variety of phylogenetic methods (Bonacum 2001). The phylogeny shown in figure 1 is the result of a maximum parsimony analysis (addition sequences = random, number of replicates = 100, branch swap = TBR). The search recovered four most parsimonious trees [length 33,181; CI = 0.31; RI = 0.53; see Bonacum (2001) for more detail]; figure 1 is from the strict consensus. Measures of support include bootstrap proportions (BP; Felsenstein 1985, 1988), and decay indices (DI; Bremer 1988). This phylogeny shown is part of a larger study treating phylogenetic relationships within the entire Hawaiian Drosophilidae (Bonacum 2001; Bonacum et al. in press) and includes several outgroups, as well as representatives of all major Hawaiian Drosophila lineages. Based on this taxon sampling, we feel confident in making statements concerning the relationships of the Hawaiian Drosophilidae and the genus Scaptomyza. Morphological analyses were done either using light or scanning electron microscopy. Specimens were prepared as follows: adult flies stored in 70% ETOH were completely dehydrated via sequential washes with 80%, 90%, 95% and 100% ETOH. These specimens were then critical point dried using standard protocols (Grimaldi 1987). Male genitalic structures were dissected from the abdomen and adhered to a specimen mount (Ted Pella, Inc.) using double coated, carbon conductive tabs (Ted Pella, Inc.). The material was sputter coated and visualized using a Hitachi S4700 Field Emission Scanning Electron Microscope. All image files were saved in.tif file format and edited in Adobe Photoshop 5.0 (Adobe Systems, Inc.). Image files are available upon request. Results and Discussion. The molecular and morphological data strongly support the notion that the genera Titanochaeta and Grimshawomyia, as well as the Drosophila subgenus Engiscaptomyza, actually belong within the genus Scaptomyza. The molecular phylogeny we present (Fig. 1) shows high support for a clade containing these three endemic Hawaiian groups with several subgenera of the genus Scaptomyza (BP = 100, DI = 24.75). Although support for the Hawaiian Scaptomyza lineage plus Titanochaeta, Grimshawomyia and the subgenus Engiscaptomyza is quite robust, relationships within this clade are not well supported. Only the monophyly of the subgenus Bunostoma (BP = 100, DI = 44.5) and the sister group relationship of S. (Scaptomyza) graminum and S. (Parascaptomyza) elmoi (BP = 100, DI = 24) are well supported (Fig. 1). The latter relationship, however, implies that the subgenus Parascaptomyza is not monophyletic. This phylogeny also calls into question the monophyly of Engiscaptomyza, placing S. crassifemur as the sistertaxon of S. chauliodon and S. nasalis as the sister of S. palata (Fig. 1). Clearly, the large Scaptomyza lineage will need to be surveyed more extensively and completely revised in order to resolve these issues.. Scanning electron microscopy was used to compare the morphology of the male genitalia of Titanochaeta, Grimshawomyia, and the crassifemur group with Scaptomyza and Drosophila. It is clear that, based on several characters, the three endemic Hawaiian groups are more closely related to Scaptomyza than they are to Drosophila. For example, the epandria and cerci of Titanochaeta, Grimshawomyia, Scaptomyza, and Engiscaptomyza are all highly modified, possessing expanded lateral lobes that often bear elongate setae (Figs. 2���6). Hardy (1965: 606) noticed these characters and cautioned against referring to them as secondary claspers because he preferred ���to use this term only for those distinctly clasper��like lobes...which bear strong spines.��� In addition, the genitalia of Scaptomyza, Titanochaeta, Grimshawomyia, and Engiscaptomyza have a more ���open��� arrangement, where the surstyli and lateral lobes of the epandrium form a ���cup��� on the ventrodistal surface of the abdomen (Figs. 2��6). This is in contrast to the genus Drosophila, where the surstyli are closely oppressed on either side of the aedeagus and lateral lobes on the epandrium or anal plates are generally absent. Chromosome studies also suggest a close affinity between Scaptomyza, Engiscaptomyza and Titanochaeta (Clayton et al. 1972; Yoon et al. 1975). The metaphase configurations (1 V��shaped, 3 rods, and 1 dot; N = 5) is shared between Scaptomyza, Titanochaeta, Engiscaptomyza and some species in the modified mouthparts species group (genus Drosophila). All other Hawaiian Drosophila species have the ���ancestral��� karyotype (5 rods and 1 dot; N = 6) for the genus Drosophila. It has been suggested that this reduction in chromosome number has taken place via centric fusion events (Patterson & Stone 1952). Our molecular phylogeny (Fig. 1) suggests that this has taken place at least twice ��� once in the modified mouthpart species and again in the Scaptomyza lineage (which contains Titanochaeta, Engiscaptomyza, and Grimshawomyia). Based on the morphological, chromosomal, and molecular evidence, we propose placing the genera Titanochaeta and Grimshawomyia into the genus Scaptomyza as subgenera. We are also moving the subgenus Engiscaptomyza from the genus Drosophila to Scaptomyza. This placement will broaden the morphological concept of the genus Scaptomyza which will, in turn facilitate further taxonomic studies on this poorly understood and complex group., Published as part of O'Grady, Patrick, Bonacum, James, Desalle, R. & Val, Francisca Do, 2003, The placement of Engiscaptomyza, Grimshawomyia, and Titanochaeta, three clades of endemic Hawaiian Drosophilidae (Diptera), pp. 1-16 in Zootaxa 159 (1) on pages 2-6, DOI: 10.11646/zootaxa.159.1.1, http://zenodo.org/record/5014208, {"references":["Fallen, F.

Scaptomyza (Grimshawomyia) Diagnosis. The genus Grimshawomyia was described by Hardy (1965) and contains two species, G. palata and G. perkinsi, the latter of which was initially described as a member of the genus Drosophila by Grimshaw (1901). The unique male genitalia, which feature surstyli that are exposed and an epandrium which is developed into a pair of moderately large lateral lobes, extending beyond the apices of the surstyli (Figs. 5��6), suggest that these taxa actually form a clade within the genus Scaptomyza. This clade is also characterized by having the second antennal segment sharply pointed at the apex, extending over the base of the third segment; the vertical and ocellar setae inserted into the somewhat swollen sides of the vertex; a long costal fringe, which extends nearly to vein R 4+5, and the distinctive wing markings. Included Taxa. Scaptomyza (Grimshawomyia) palata (Hardy), comb. nov. from Maui and O���ahu, and S. (Grimshawomyia) perkinsi (Grimshaw), comb. nov. from Maui, O���ahu and Hawai���i (Nishida, 2002). KEY TO SPECIES OF THE SUBGENUS Grimshawomyia Hardy 16.

Scaptomyza (Engiscaptomyza) Diagnosis. Mesonotum typically with five dark brown to black vittae extending the full length, the lateral vittae may be interrupted at the suture (Kaneshiro 1969). The male genitalia of the Engiscaptomyza species are also quite similar to those of the genus Scaptomyza, characterized by large lobes of the epandria and prominent surstyli (Fig. 4). Some species (i.e., S. crassifemur) also possess enlarged, swollen femora. Included Taxa. Scaptomyza (Engiscaptomyza) ampliloba (Hardy), comb. nov. from Kaua���i, S. (Engiscaptomyza) crassifemur (Grimshaw), comb. nov. from Maui and Moloka���i, S. (Engiscaptomyza) inflata (Kaneshiro), comb. nov. from O���ahu, S. (Engiscaptomyza) lonchoptera (Hardy), comb. nov. from Maui, S. (Engiscaptomyza) nasalis (Grimshaw), comb. nov. from Maui and Moloka���i, S. (Engiscaptomyza) reducta (Hardy), comb. nov. from Hawai'i, S. (Engiscaptomyza) undulata Grimshaw comb. nov. from Hawai���i (Nishida 2002) Discussion. Kaneshiro (1969) recognized a single species group (crassifemur) containing two subgroups (crassifemur and nasalis) within this subgenus. We will leave all taxonomic ranks below the level of subgenus intact. The polytene chromosome of the subgenus Engiscaptomyza, unlike those of the remainder of the genus Scaptomyza, are large and easy to decipher. Yoon et al. (1975) examined the phylogenetic relationships between four species of the subgenus Engiscaptomyza using polytene chromosome banding patterns. Their work suggests that S. reducta (Hawai���i) and S. crassifemur (Maui Nui) are sister taxa. Scaptomyza inflata (O���ahu) is basal to this group and S. ampliloba (Kaua���i) is the most basal member of this subgenus. KEY TO SPECIES OF THE SUBGENUS Engiscaptomyza Kaneshiro 10.

The phylogenetic relationships among megabats (Order Chiroptera: Suborder Megachiroptera) are still under investigation. Previous studies using molecular data to investigate the systematics of megachiroptera have relied mainly on mitochondrial genes (12S, tRNA-Val, 16S and cytochrome b). Three nuclear loci, RAG1, RAG2 and VWF, have already been sequenced for this study from 22 species samples available at the American Museum of Natural History collections. In order to complete the existing dataset, 49 samples representing 23 species were obtained from the Field Museum of Natural History (Chicago, IL), the Museum of Vertebrate Zoology (University of California at Berkeley), the Carnegie Museum of Natural History (Pittsburgh, PA), and the Lubee Foundation (Gainseville, FL). A total of 45 different species, including representatives from all the main megabat suprageneric groups, have been included in this study. DNA was extracted from 49 newly obtained samples followed by PCR and sequencing for the three nuclear loci. The mitochondrial cytochrome b gene was also sequenced for all 49 new samples in addition to the 29 samples that were available at the AMNH, for a total of 78 individuals. Sequences were edited using Sequencher version 4.2 (Gene Codes Corp.) and aligned with Clustal X. Aligned sequences were combined generating a matrix of more than 4,000 base pairs. Selected species of microchiroptera were used as outgroup. Phylogenetic analyses were run in the software program PAUP * using maximum parsimony, and statistical support for branches was obtained using the bootstrap method. The results of the combined analyses give strong support for the monophyly of the megabats and increase the resolution and statistical support of relationships between species and genera.

DNA Barcoding is a technique that can help to discover, characterize, and distinguish species using short DNA sequence from a specific gene. Because of the decline of taxonomic experts, developing a system that utilizes DNA as a taxon (barcode) can help identify many species. The utility of barcoding rests on the two assumptions: 1) the genetic distances between individuals within a given species are very small, 2) the genetic distance between species are relatively large. These assumptions have not been tested for all groups of organisms. The aim of this work is to obtain a DNA-based identification system for the Whiptail Lizards (Cnemidophorus and Apidoscelis) using a single mitochondrial gene, the cytochrome C oxidase I (COI) and to see how closely the two species are related. In our experiment, we challenged the utility of barcoding when applied to these particular groups of organisms. DNA was extracted from 96 tissues (heart, liver, tail, nucleated blood) samples using the standard DNeasy protocol for animal tissue. PCR was then performed using universal COI primers. The cleaned PCR products were sequenced using Big Dye Chemistry and the ABI3730 automated sequencer. The sequenced data were annotated and corrected using Sequencher version 4.2. Of the 96 DNA samples that were successfully extracted, the polymerase chain reaction amplified 23 and meaningful sequences were obtained for 9 samples. Phylogenetic analysis were run in the software PAUP * using maximum parsimony. As a preliminary result, the two different species showed no differences in the COI barcoding indicating that the DNA barcoding may not be applicable to all species. Therefore patterns of genetic distance within groups should be carefully considered.

The main purpose of the project was to test if phenotypically similar populations of bivalves from the genus Pinctada from different localities throughout the world are one species or several distinct species. Variation in their shapes and colors is immense in each population therefore these populations have been classified as different (for example P. fucata in Japan and P. imbricata in the Caribbean Islands). To address this question, we used a geometric morphometric approach. First, a digital database was created to take pictures of the shells from different localities, e.g. Western Atlantic, Indo-Pacific region, the Mediterranean Sea. One hundred twenty-seven pictures of the right valves were taken and ten landmarks were marked from each shell in the interior surface. The anterodorsal extremity of the shell is marked by the first landmark, the anterior pedo-byssal retractor muscle scar is marked by the second landmark, the third landmark is the accessory pedobyssal retractor muscle scar, the fourth landmark marked the posterodorsal extremity; and so on. To analyze the variation of their shapes, two programs have been used, TpsDig and TpsRelw. The TpsDig program was used to define and capture landmarks and to also increase image contrast. The TpsRelw program used the thin plate spline function to compute relative wraps and to visualize variation in shall shape. Preliminary results do not show significant variation in the shapes of the shells from different geographical areas. In conclusion, the shells from different localities potentially represent a single species. This hypothesis will be further tested with genetic data.
