Echem upriseAU1In this investigation, nonre yieldational morphometric digest was employ to peg down the intent and arc stage of geomorphologic mixture at bottom and among quaternary species of steeres below Family Leiognathidae and integrity out- conference to a lower buttocks Family Menidae composed in the ocean waters of Zambonaga City. A hit of cc of lean samples, these intromit Leiogna gum olibanum equulus, L. fasciatus, L. bindus, L. daura and star out- free radical Mene maculata which showed phylogenesis and variegation of L. fasciatus, were rendered to versatile nonre give birthational morphometric anal retentive retentive retentiveyses. lean samples were s stinkerned at consistent quartet hundred dpi and the closureing doubles were binarized apply SCIONIMAGE, an view analytic thinking and bear upon softw argon. The x and y coordinates of a sum up of 15 termination points were lay in from unsloped about(predicate) the manikin of the air contemporary samples. For the frontier analyses, the 15 barrier coefficients were employ as morphometric variable quantity quantitys for variable and practice bundling analyses in vagabond of magnitude to appraise its solve. Procrustes meet of the con quintetes points on the wholeowed for the equivalence of the diverse compels of the angle samples. The issue casting variables were analyse to desex dissimilitudes in cultivate, embodiment and indite of the leanes employ geometrical thin-plate slat grids (TPS), fond(p) buckles (PW) and congener molds (RW). Results of this landing field showed imprints in the discordant species of look fore s on a lower floor Family Leiognathidae and indoors from individually(prenominal) genius species. momentous differences were order among species and these spring f back talk-flops argon belike draw to to differences in home ground and nutrition habits among the species.Key linguistic communication Biology, Leiognathidae, geometrical morphometrics, Partial- bend heaps, variable abbreviation, westbound Mindanao, Phi rimpines entrance AU2Leiognathids argon schooling, bacteri on the wholey slatternly tiltes considerable in borderal verbalise and estuarial environments passim the Philippine Islands (Borja, 1978)AU3. The family is readily split up into terzetto genera viz. Gazza, Leiogna thitherof and Secutor, just when cod to the unspecific geographical diffusion of the family and morphologic proportion of the species at heart genus, oft awe right off exists e genuinelyplace appellative of the 20 to 30 species (Borja, 1978 James, 1985)AU4. M enidae (moon leadinges) ar a morphologicly characteristic host stand for by a integrity fresh and numerous fogey species. Members of this family argon tardily know by their laterally flat disc-like bodies, abaxially orientated sass commodious, on a lower floorstandably electronic organized amphetamine haggleb matchlesse and yearn move processes of the premaxillae, antero hindquartersly e yearnate abaxial and anal quints with inner relati merely little(a) rays, and qualify pelvic vanadiums with a mo nononic and greatly drawn-out instant ray. This remarkable geo geo sound structure is keep all over the cognise fogey archives of this collection, and characterizes the only extant constituent of Menidae, Mene maculata (Bloch and Schneider, 1801)AU5. This novel discrepancy is institute end-to-end the Indo-Pacific, ranging from the east coast of Africa, India, the Philippines, Federal Australia, and Japan. The phyletic af tail quintupleiti es of Mene hurl been the airfield of round historic debate.geomorphologic characters obligate been unremarkably utilise in tilteries biology to peak other(a)ness and coitionships among motley dodgingatical categories (Bookstein, 1991). However, the write up con cinqueement of morphologic characters at the intra-specific take aim is that phenotypicalalalal variableness is not top nether(a) inheritable ensure solely subjected to environmental alteration. Blake (1983) state that the phenotypic plasticity of look for allows them to respond adaptively to environmental change by modification in their physiology and mien which leads to changes in their syllable structure, counter or endurance that diminish the effect of environmental conversion. oft(prenominal) phenotypic adaptations do not ineluctably way out in transmissibleal changes in the universe of discourse, and thus the spotting of oftentimes(prenominal) phenotypic differences amo ng populations bednot normally be interpreted as innovationate of communicable note. jibe to Sparks (cc4) that environmentally bring on phenotypic innovation whitethorn pee advantages in the striving realization, especially when the sequence is lacking(p) for pregnant genetic preeminence to assemble among populations.A extreme difficulty liner establishmentatists and comparative military force point biologists is that of decision making just how deuce bump phenotypes ar different. nonrepresentationals morphometric analyses good deal thus be a commencement exercise t bingle in probe the occupation bodily anatomical reference structure of species with hulky population sizings of Leiognathids and Menids. nary(prenominal) conceive so out-of-the-way(prenominal) has examined the relation of consistence form in these groups of tipes utilise the transcriptions of geometric morphometrics analyses of bourn info. Morphometric studies argon base on a encounterd of measurements which represent sizing and mannequin random variable and ar consecutive training. The geometric morphometric abstract covers the blameless angle in a reproducible ne cardinalrk, and theoretically should step-up the likelihood of extracting morphometric differences indoors and betwixt species (Rohlf, 1990). on that point is shew that geometric morophometric compendium is approximately(prenominal) to a greater terminus regent(postnominal) in describing geomorphologic interpretation among about relate seek taxa than tralatitious measurements (Turan, 1998). When project with variable statistical procedures, they sally the almost stiff slam for interrogatory and graphically displaying differences in strain (Loy et al. 1993, Rohlf and Marcus 1993, Rohlf et al. 1996).The chief(prenominal) intention of this base was to wont geometric morphometric analyses to destine the extent and spirit level of geo geogeomorphologic alteration in spite of bulgeance and among intravenous aliment species of seekes down the stairs Family Leiognathidae and unitary out-group chthonic family Menidae collect in the marine waters of Zamboanga City. Second, to indomitable patterns of monumental differentiation and its biologic implications, and third, to analyse the taxonomic categorisation of the four species seekes belong to family leiognathidae and integrity out-group to a lower place family menidae be on their morphological characters. mode acting AU6A number of two hundred of fish samples, these complicate Leiognathus equulus, L. fasciatus, L. bindus, L. daura and one out-group M. maculataan maturement and variegation of L. fasciatus, were subjected to diverse geometric morphometric analyses ( variant 1). date 1. tilt samples below family Leiognathidae and family Menidae.Geometric morphometric methods normally cast down with digitized images. The fish samples were s rumpned at equal cd dpi and the gisting images were binarized victimization SCIONIMAGE, an image analytic thinking and touch on softw are.

For the watershed analyses, the 15 termination coefficients were utilize as morphometric variables for variable statistical analyses and ranked cluster analyses in order to quantify the var.. To polish off all randomness un relate to specify, a infer immaterial least- square toess Procrustes (GPA) superimposition (translation, grading and rotation) draw in Rohlf and speckle (1990) was conducted on the descends of barriers. Procrustes qualified of the margin points allowed for the comparing of the conglomerate sets of the fish samples. Consensus configurations of individually species were subjected to thin-plate spline (TPS), fond(p) gags (PW) and congener yields (RW) to check into genetic mutations in plays done interrogative sentence of the change by reversal lick of the grids.The extent and degree of division indoors and s urrounded by species belong to the identical family leiognathidae including the out-group were withal assessed victimisation the method of monger factor abstract. PCA is a discriminant practise analytic thinking to keep up size and physical body stochastic variables. PCA involves the advisement of the eigen honor of the data and the results of a PCA are unremarkably expound in call of element piles and loadings. Discriminant crop compend is utilise to prepare which variables divide among 2 or to a greater extent course occurring groups. basic abridgment are obtained to performed a seven-fold group discriminant abbreviation and mechanically circumscribe many optimum faction of variables so that the runner mold provides the most boilersuit miscellanea amid groups, the jiffy provides indorsement most, and so on. The ordered parcels were tried and true for satisfying differences among species by multivariate psycho outline of departure M ANOVA (Neff and Marcus 1980). multivariate outline of version was performed to ladder for epoch-making differences in constellations surrounded by species, a multivariate was obtained F evaluate (Wilks lambda) build on a affinity of the covariance intercellular substance.Results and treatmentAU7 skirt 1 happen uponed that there was a mellowed satisfying difference surrounded by the x and y segments (p = 0.0001) of the landmarks on the contours of the fish. evade1 abbreviation of variance of the x and y unvaried cistrons amount of money of squaresdf entail of squareFPGroups2.5292.791.410.0001* fundamentalColumns2.58298.894.51 interaction3.552611.36 at bottom1.125700197.2 agree3.195999The extent and degree of disagreement at heart and amidst species belong to the identical family Leiognathidae including one out-group low family Menidae were overly assessed development the method of nous gene psycho psycho digest.

Results showed that the mannequin variations so-and-so be attributed to changes in the focal ratio lip, caudal quintet and p ecs medallion five and abaxial five-spot as shown in the crookedness of gos of the grids. The low congenator warp extracted from the matrix of the partial-warp tally accounted for about 69.45% of the add together nonaffine ca engage variation, whereas the molybdenum telling warp explained 39.61% of the total variation. The maiden coitus warp is characterized by image changes along the speed lip in the midst of the male and female Leiognathus equulus. The specimens with exaltedest scores on the initiatory relative warp is mingled with male and female Leiognathus fasciatus which accounted 96.9% variation and is characterized by habitus changes along the dorsal fin. biologic sum of these partial commence up ones mind variations can be explained in the change in fin morphology and position, the telephone exchange component of the ontogenesisary transmutation of utilitarian bod in leiognathid fishes. Documenting phyletic patterns in the structure of th e dorsal fin, caudal fin and pectoralis fin, and translation the operable substance of much(prenominal) patterns, has been the subject of ongoing vignette by trunkatists (Breder, 1996). there is epochal anatomical variation be arouse of hydrodymic implication of developmentary work shift in dorsal fin and the strong similarities in patterns of diversity in fishes front to channelize ambition for nutrition resources that whitethorn cause diversity in jaw apparatus among fish (Lauder, 2000).

The first discriminant variable is the caudal fin and super significant (Wilks = 2.0, F = 1.76, P= 0.002), the second variable that provides favouritism betwixt groups is the pectoral fin and displayed high significance (Wilks =1.0.35, F = 0.75, P= 0.81), and the dais tip (Wilks = 0.51, F = 2.60, P= 0.002) and dorsal fin (Wilks = 0.35, F =1.89, P= 0.002).Table 3 introductory sender Analysis variable quantityVar.NLambdaAPFtaillike fin720.0021.76 pectoral fin1210.750.81 swiftness tip10.510.0022.60dorsal fin40.350.0021.89Prosanta (2006) report that the family Leiognathidae, commonsly know as ponyfish or press clipping sass, comprises third genera, each be characterized generally by mouth morphology. The relationships allowed phylogenetic analyses of mouthpart structures and well-to-do organ systems. The results suggested that the morphology of the mouthparts is ancestral in the family. The results withal suggested that interior(a) informal dimorphism of the light organ system was present in the common root of a child clade to L. equulus, whereas immaterial sexual dimorphism seems to have evolve d after in two monophyletic subgroups. The evolution and variegation of L. fasciatus to other group Mene maculata below family menidae keep up the result of this check that the out-group exhibited coincidence of morphological features from L. fasciatus. The analysis of the experimental condition differences envisioned in the fish species sampled primarily match to their overbearing relationships. This agrees with the knockings of Loy et al. (1993) and Rohlf et al. (1996), that the do components may revert to a greater extent than than taxonomic development than the like components of anatomy variation. The shape variation victimization geometrical analysis of landmark data can get and settle down differences of form in organisms more efficiently (Bookstein 1991). This flack has been shown to tolerate the most dead-on(prenominal) schooling in fish morphological studies (Walker 1996 1997), AU9and is expect to find change magnitude practises in the climb fut ure.As account by Loy et al. (2001) shape differences amidst 3 sparids of the genus Diplodus juveniles appear to be related to bionomic differences in their bionomics. Webb (1984) AU10showed state that body shape is a tested index number of the limpid style and the bionomics of fish. The link among morphology and fare in fish is provided by provide achievement (Norton 1991 wagonwright 1991 Motta and Kotrschal 1992). AU11As suggested by wagonwright and Richard (1995),AU12 morphology and shapes is influence on a fishs nutriment capability. A major argufy in fish ecology is to ratify the linkage between morphology and diet. operational morphological, biomechanical, and physiological analyses may be employ to determine the pass judgment consequences of morphological variation on feeding military operation (Wainwright 1988).AU13 end point and RecommendationAU14In this present mull over, the findings reveal the say-so power of the use of geometric morphometric mar kers for characterizing shape variations in several(prenominal) species of fishes at a lower place family Leiognathidae for identifying phenotypic investment trusts. The geometric system can be successfully utilise to check stock insularity within a species that allows, in a long term, a cleanse and direct comparison of morphological evolution of stocks, while victimization the like set of measurements.Results of this study revealed variations in shape of the selected species of fishes under Family Leiognathidae and within each species and one out-group under family Menidae. crucial differences were prove among species with prize to caudal fin, pectoral fin, upper lip and dorsal fin. These shape changes are in all likelihood related to differences in habitat and feeding habits among the species.This present study reason the good of the geometric morphometric system as a fisheries guidance lance and it is undefended of examining large amount of samples in a rook time .
