The study investigated morphometric and meristic measurements, length-weight relationship (LWR) relative condition factor (Kn) of the Sphyraena obtusata from south-eastern Arabian Sea August 2019 to March 2020. Three hundred fifty two specimens having a length weight range 16.5 – 30.1 cm 29.54 155.20 g, respectively were analyzed for morphological measurements (13 11 meristic), LWR factor. maxi...

OBJECTIVE This study compared actual 6 minute walk test (6MWT) performance with predicted 6MWT using previously validated equations and then determined whether allometric modelling offers a sounder alternative to estimating 6MWT in adults aged 50-80 years. METHODS We compared actual 6MWT performance against predicted 6MWT in 125 adults aged 50-85 years (62 male, 63 female). In a second sample...

The surface area-to-volume ratio of cells is one of the key factors affecting fundamental biological processes and, thus, fitness of unicellular organisms. One of the general models for allometric increase in surface-to-volume scaling involves fractal-like elaboration of cellular surfaces. However, specific data illustrating this pattern in natural populations of the unicellular organisms have ...

The allometric relationship between body mass and gonad mass in males of 23 fish species from 11 families was examined. There was no evidence of a single allometry for all fishes. A cross species analysis suggested a scaling coefficient of 1 04, which was significantly different from a previous study that reported a scaling coefficient of 0 904. A within species analysis generated scaling coeff...

the length-weight relationships for three fish species from beheshtabad river, karun river drainage (western chaharmahal and bakhtiari provinces, iran) were investigated. the values of the slope parameter ( b ) in the length-weight relationship equations were determined as 2.79 for capoeta damascina , 3.10 for chondrostoma regium and 3.09 for oncorhynchus mykiss , all of which were significantl...

It has been hypothesized that most morphological evolution occurs by allometric differentiation. Because rodents encapsulate a phenomenal amount of taxonomic diversity and, among several clades, contrasting levels of morphological diversity, they represent an excellent subject to address the question: how variable are allometric patterns during evolution? We investigated the influence of phylog...

Abstract Lake Mahalona is one of the lakes located in Malili Complex, South Sulawesi and included Natural Tourism Park Area. Cichlasoma trimaculatum are ornamental fish from Cichlidae family that become invasive Mahalona. A total 29 species were recorded this lake, most them endemic fish. It estimated native populations will decline due to alien intentionally or unintentionally The study determ...

Length-weight relationship and condition factor were estimated in seven fish species, including Barbus cyri, Capoeta gracilis, Alburnoides eichwaldii, Pseudorasbora parva, Ponticola cyrius, Cobitis keyvani and Acanthalburnus microlepis from Shahrbijar River, Guilan Province, Iran. A total of 416 specimens ranging from 18 to 135 mm in total length and from 0.06 to 19.25 g in total weight were co...

BACKGROUND Carbon accounting in forests remains a large area of uncertainty in the global carbon cycle. Forest aboveground biomass is therefore an attribute of great interest for the forest management community, but the accuracy of aboveground biomass maps depends on the accuracy of the underlying field estimates used to calibrate models. These field estimates depend on the application of allom...
