Stratification strength and light climate explain variation in chlorophyll a at the continental scale in a European multilake survey in a heatwave summer

MEHMET TAHİR ALP

To determine the drivers of phytoplankton biomass, we collected standardized morphometric, physical, and biological data in 230 lakes across the Mediterranean, Continental, and Boreal climatic zones of the European continent. Multilinear regression models tested on this snapshot of mostly eutrophic lakes (median total phosphorus [TP] = 0.06 and total nitrogen [TN] = 0.7 mg L−1), and its subsets (2 depth types and 3 climatic zones), show that light climate and stratification strength were the most significant explanatory variables for chlorophyll a (Chl a) variance. TN was a significant predict ...Daha fazlası

Mersin sahilinde Dağılımı Bulunan Ulva rigida (C. Agardh 1823)'nın Yağ Asidi Profilinde Bölge Farklılıklarına Bağlı Değişimler

MEHMET TAHİR ALP | NAHİT SONER BÖREKÇİ | DENİZ AYAS

Çalışmada kullanılan Ulva rigida örnekleri Mersin sahilinin farklı noktalarından (1. istasyon; Çamlıbel, 2. istasyon; Karaduvar, 3. istasyon; Marina, 4. istasyon; Hilton) 2016 yılında ilkbahar mevsiminde toplanmıştır. U. rigida’nın toplam yağ ve yağ asidi düzeyleri belirlenmiştir. Toplam yağ düzeyi için sırasıyla 1. istasyon %0.87, 2. istasyon %1.03, 3. istasyon %0.41, 4. istasyon %4.99 olarak bulunmuştur. Dominant doymuş yağ asitleri (SFA) palmitik asit ve stearik asittir. Palmitik asidin en yüksek düzeyi 4. istasyon örneklerinde %40.64, en düşük düzeyi ise 1. istasyon örneklerinde %27.78 ola ...Daha fazlası

The Economic Importance of Macroalgae

MEHMET TAHİR ALP | DENİZ AYAS

In this study, we discussed algae with economic importance. Information was given about the use of macroalgae in the food industry, medicine and pharmacy, additives, organic agriculture, wastewater treatment, and bioplastic production, which are the areas of use in the economy. The taxa and species used in these areas were investigated. Macroalgae in the seas of our country were examined, and information was given about how they can contribute to the economy

Determination of Effects of Seasonal and Sampling Area on Ulva Rigida’s Elemental Composition

MEHMET TAHİR ALP | NAHİT SONER BÖREKÇİ | DENİZ AYAS

Macroalgae is used as a bioindicator for their accumulation capacity of potentially hazardous elements. Ulva spp. was used extensively in previous studies as in the recent study. Along the Mersin coast, sampling was made in four different locations (Çamlıbel Marina, Pozcu Marina, Deniz Feneri, Karaduvar) during the spring and summer seasons between 2015-2016. For elemental analyses, ICP-MS was used, and Mg, Al, K, Ti, Cr, Mn, As, Se, Sr, Mo levels were analyzed in Ulva rigidasamples. The highest level (134960.0 μg g-1) was found in the elemental analysis of Mg, and the lowest levels (20.83 μg ...Daha fazlası
