Patterns of succession in Lau Basin hydrothermal vent communities determined with high-resolution imagery and in situ physico-chemical data collected over 4 yr and analyzed within a Geographic Information System show that Alviniconcha snails are a pioneering group, the snail Ifremeria nautilei is a mid-successional species, and the heat-intolerant mussel Bathymodiolus brevior dominates when venting declines. The associated fauna also changes as communities progress through the successional stages, and eventually non-vent-endemic deep-sea species appear when venting has mostly subsided. This is a unique example of primary succession in which the primary producers form symbiotic associations with mobile animals, resulting in successional patterns not observed in other systems. I. nautilei dominates newly formed substrates or venting sources where both I. nautilei and Alviniconcha spp. are already established (e.g., by migration), while Alviniconcha spp. seem to be better at colonizing newly active vents (e.g., by settlement) that are remote from colonized vents. Thus, on the scale of a 5-39 m(2) diffuse flow area or a single edifice, the mid-successional species dominates new substrates instead of the pioneering group. These communities are remarkably stable over long time periods relative to other hydrothermal vent regions. In addition to the sequential replacements of species as sites age and overall conditions change, Lau vent animals track changes in vent fluids and relocate themselves when local hydrothermal plumbing changes over small spatial scales.

Composition of eggs and larvae of fish and macrogelatinious zooplankton in Sinop Region (The Central Black Sea) during 2002 Satilmis, Hasan Huseyin; Bat, Levent; Ozdemir, Zekiye Birinci; Ustun, Funda; Sahin, Fatih; Kıdeyş, Ahmet Erkan; Erdem, Yakup (2006-01-01) This study was carried out in order to determine abundance and distribution of macrogelatinous organisms (Aurelia aurita, Pleurobranchia pileus, Mnemiopsis leidyi ve Beroe ovata) with respect to fish egg and larvae in Sinop region in 2002. Three stations were selected this region and plankton tows were made both verticallly and horizontally. In study the ctenophores M. leidyi between January and September, and B. ovata between August and December period were appeared. The cnidarian Aurelia aurita and the ct...
Population dynamics and ecology of the invasive veined rapa whelk, Rapana venosa in the southern Black Sea MUTLU, ERHAN; Kıdeyş, Ahmet Erkan; Şahin, Fatih; Erik, Gökhan; Aksu, Hakan; Erdem, Ercan; Karayücel, Sedat; Bat, Levent (2022-05-05) © 2022 Elsevier LtdSpatial and temporal changes in some ecological characteristics (i.e. biomass, abundance, morphometrics, sex-composition, growth parameters and population dynamics) of the invasive veined rapa whelk (Rapana venosa) were studied off Sinop Bay, in the southern Black Sea. The whelk specimens were sampled from three depths (15 m, 25 m and 35 m) at monthly intervals between November 2005 and October 2007. Custom-made pots were deployed for the capture of R. venosa individuals. Monthly distribu...
Phylogenetic differentiation of Aegilops and Triticum species by using ATR-FTIR spectroscopy Demir, Pinar; Önde, Sertaç; Ozgen, Murat; AVCI BİRSİN, MELAHAT; SEVERCAN, FERİDE (2012-11-01) Triticum and Aegilops species belong to the Poaceae family and show common morphological traits. These morphological common traits made it difficult to identify and name the concerned species. In addition there is great disagreement even in nomenclature of genomic make up. Therefore molecular identification of these species becomes the preferred approach. The study in concern aims to make a phylogenetic differentiation of 8 Aegilops and 4 Triticum species by using Attenuated Total Reflection-Fourier Transfo...
A Survey of Niche Overlap and Adaptive Trait Responses of Turkish Honeybee Subspecies to Climate Kükrer, Mert; Bilgin, Cemal Can; Turak, Ayşe (2016-11-05) Introduction: Over 24 subspecies or “geographic races” of honeybees in the world appear to have diversified following isolation during the Pleistocene glaciations. Research on their differences in morphology, biogeography, behavior and genetics suggest that Turkish races belong mostly to the same lineage, but evolved in extremely different habitats. Foraging strategies, honey storage, production of young, overwintering success, swarming behavior or aggression show differences between races. Such traits migh...
Molecular phylogenetic position of Turkish abies (pinaceae) based on noncoding trn regions of chloroplast genome Özdemir Değirmenci, Funda; Kaya, Zeki; Department of Biology (2011) Abies is the second largest genus of family Pinaceae (after Pinus), consisting of about 51 species, all native to the Northern Hemisphere. There are six native taxa belonging to this genus growing in pure and mixed stands in Turkey. Abies cilicica subsp. isaurica, Abies nordmanniana subsp. bornmülleriana, Abies nordmanniana subsp. equi-trojani, Abies x olcayana are endemic and considered as lower risk (LR) species. To determine the genetic relationships in Turkish firs, 18 populations of different subspecie...
