In July 2017, three specimens of an alien fish species were caught by the amateur fishermen in Kızılırmak River at Sivas city center. One of the fish specimens was taken from the fishermen for ichthyologic examination. The morphological, metric (23 features) and meristic characters (13 features) of this specimen were determined. The alien fish is with ovoid shape and flattened laterally. Mouth is in a sub-ventral position. The tooth row is double. Teeth formula are 3,2 / 2,3 (at first row on maxil) and 2 / 2 (at second row on maxil), 3,3 / 3,4 (at first row on mandibul), 1,1 (at second row on mandibul). The number of rakers on the first gill arch is 33. The scale numbers in line lateral are 107 (on right side) and 103 (on left side). The number of branched rays of dorsal, anal, pectoral, and ventral fins are 14, 24, 14, and 7; respectively. As a result of the evaluation of morphological, metric and meristic characters, it was decided that the alien fish caught from Kızılırmak was Piaractus mesopotamicus (Holmberg, 1887) belonging to the Characidae family. This species is also called as the small-scaled pacu. P. mesopotamicus is not among to native fish fauna of Kızılırmak. It is a fish species which originated from South America and is a tropical freshwater fish. These alien fish specimens which were caught by the amateur fishermen, probably translocated from a hobbyist aquarium to this aquatic system. Both directly and indirectly, invasive fishes affect a wide range of native organisms from zooplankton to mammals across multiple levels of biological organizations ranging from the genome to the ecosystem. This study is the first scientific record for Sivas aquatic systems related to alien fish species.

In this study, the effects of grape seed extract on insulin, adiponectin and resistin levels in diabetic rats were aimed to investigate. Weight of about 300-350g 7-8 weeks 32 female Wistar Albino rats were used. Weight of about 300-350g 7-8 weeks 32 female Wistar Albino rats randomly divided into four groups of eight each: control group (C), group with diabetes (DM), grape seed extract group (GSE), diabetes mellitus and grape seed extract group (DM+GSE). The diabetic group 45 mg/kg single dose of streptozotocin was administered intraperitoneally, and the grape seed extract groups (DM+GSE and GSE) grape seed extract was given orally every day with an intragastric tube for 20 days (0.6 ml/rat). Blood samples were taken from the hearts of rat’s end of the experiment. The sera obtained were used for insulin, adiponectin and resistin analysis measured via ELISA with commercial kits. The insulin and adiponectin levels of the rats in the diabetes + grape seed extract group were found to be higher than those in the diabetes group. There was no significant change in the resistin level differences between the groups. As a result; It is possible to say that grape seed extract has an increasing effect on insulin level and adiponectin levels of diabetic rats are decreased due to diabetes and it has no significant effect on resistin levels. Detected by the positive effects of grape seed extracts, it may be useful to use for the regulating of the diabetes in human.

For many seeds, cold press technology generates higher quantities of cakes than seed oils, which are concentrated in proteins. Valorization of the cakes could offer a viable strategy to manufacture protein fortified foods with comparable characteristics as the conventional products. Here, black cumin, grape seed and pumpkin seed protein concentrates were prepared based on an alkaline extraction-isoelectric precipitation technique. The influence of protein concentrate addition on the flour, dough and bread characteristics were investigated for textural profile, gluten quality and visual characteristics including color attributes. While the interactions between gluten and seed proteins were mostly weak, some of the physicochemical attributes differed significantly. In terms of volume and visual characteristics, pumpkin seed protein concentrates enriched bread demonstrated similar characteristics as the controls, while black cumin or grape seed protein concentrate enriched wheat flours were more resistant and less extensible than the controls. Similarities and differences between controls and protein enriched gluten-free or gluten-bearing bread were discussed.

In recent years, there have been unexplained colony losses around the world. Due to the decrease in honey bee colonies, many studies have been carried out to investigate potential causes. One of the main causes of losses is also insecticides. Insecticides used against harmful insects in agricultural fields affect not only harmful ones but also beneficial insects such as honey bees directly or indirectly. Honey bee losses are more common, especially where insecticides are used, and the immune systems of bees exposed to insecticides in these areas weaken; foraging behavior, the ability to smell and learn is impaired. In addition, it leaves residues in bee products such as honey, wax, pollen and bee bread. Effective and sustainable solutions are sought worldwide in order to cope with these losses that pose a major ecological threat. This review aims to reveal the current situation by examining the effects of insecticides on honey bee behavior and physiology.

Increasing population and challenges among the sectors due to the climate change and incorrect water policy has increased the pressure on water resources. This situation being as a global crisis particularly in respect to the food security has accelerated productive utilization of water supplies. The aim of the current study with 2-year experiments was to identify the effect of different irrigation interval and irrigation regimes on the yield and yield components of dry bean having greater than 50% of total world legumes production. In that experiment, two different irrigation interval, 7 and 14-day, and three different irrigation levels, (I100, I75 and I50, were studied. In results, the maximum yield was obtained from 7-day irrigation interval, and 28% yield reduction was detected at 14-day irrigation interval. In examine the irrigation levels, the highest yield was found at full irrigation (I100), and increasing water stress caused significant yield reductions e.g. 21% and 49% for I75 and I50, respectively. The evapotranspiration and total applied water as an average of 2013-2014 were calculated as 533 mm, and 450 mm, respectively. In assessment of the both the combine year results, the ky value was determined as 1.59, and this finding shows that dry bean crop is sensitive to the water stress condition.

The aim of the study was to describe the scenario of the present condition of production and management system of dairy buffalo at Haor areas of Sylhet in Bangladesh. Data were collected between February 2019 and January 2020. Sixty dairy farmers and thirty indigenous dairy buffaloes were selected for the study purpose. All respondent farmers were male and 65% were in between 40 to 50 years of age. Parity number had a significant relation in response of body weight. Quality analysis of milk showed that buffaloes which were reared at Haor areas have more fat content on an average 7.88% than buffaloes which were reared conventional dairy farm containing 7.34%. Price of buffalo’s milk and meat were varied with the seasonal changes, lower in winter season. All farmers fed the buffaloes only with green grass in winter. Four major diseases of buffaloes were found in Haor areas where the percentage of foot and mouth diseases was 15.59% followed by black quarter (11.01%), anthrax (7.34%) and hemorrhagic septicemia (6.42%). The buffaloes were not dewormed so parasitic infestations dramatically increased and easily transferred from one to another. The farmers had not enough knowledge about regular vaccination. But in contrast with profitability, total benefit cost ratio from buffalo rearing was 1:1.56 annually.

The study was carried out to the effects of different plant densities and nitrogen levels on okra yield and plant development. Field trials were conducted in two locations, the training fields of the Ege University, Ödemiş Research and Training area, and Ege University Faculty of Agriculture, Menemen Research and Training Farm. The field layout was a split-plot design with 3 replicates, where main plots consisted of nitrogen applications and sub-plots of plant densities. Fertilizer was applied in the form of Triple Superphosphate, Potassium Sulfate, Urea and Ammonium Nitrate. Five different nitrogen levels (F1: 0, F2: 40, F3: 80; F4: 120 and F5: 160 kg N ha-1) and two different rows spacing (PD1: 15 cm×70 cm and PD2: 25 cm×70 cm) have been tested. Yield and yield components, plant height at flowering, height of the first fruits, the number of leaves, the number of branches, the number of days from sowing to first flowering, the number of days from sowing to first harvest, plant height, foliation status, total yield, yield of plant, average fruit weight, fruit length, fruit diameter have been noted in the field experiments. Total yield ranged from 5923.8 to 12888.9 kg ha-1 at the Ödemiş location, while it was 3363.3-5009.2 kg ha-1 at the Menemen location. In conclusion, the highest yield is taken from F2 in both plant densities in Ödemiş. In Menemen, the highest yield is taken from the dose of F3 (80 kg Nha-1) and F4 (120 kg Nha-1).

As it is common in tropical and temperate zones, mullet species constitute the most important fish species caught along the coast and estuaries of Turkey. In terms of ecology, tourism and and fish productivity (52 kg/ha), Koycegiz-Dalyan Lagoon Ecosystem (KDLES) is the most important lagoon, with a 5500 ha surface area, is the Mediterranean Coast of Turkey. In the dalyan (barrier fish trap) systems; approximately 225 tons (80-405 tons) of mullets are caught to obtain 5 tons of dried fish eggs per year. Seventy percent of fish production in the lagoon is composed of mullets. The mullet samples were collected monthly between October 1992 and September 1994 from eight stations (one of them is a marine station) by trammel nets. The ages were determined using by scales anda ge composition varied form 0 to 6 ages. Species composition of 1159 sampled individuals were proportionally determined as Mugil cephalus 45%, Liza aurata 35%, Liza saliens 14%, Liza ramada 12%, Chelon labrasus 6%. The growth performance indices calculated from von Bertalanffy growth parameters using by all individuals for the M. cephalus, L. aurata, L. saliens, L. ramada and C. labrasus were determined as 2.957, 2.866, 2.692 and 2.719, respectively. The highest growth performance index was calculated for M. cephalus. The growth performance indeces of mullet species in Köyceğiz-Dalyan Lagoon Ecosystem were found around the world averages.

This study was conducted in the Aegean region conditions of Turkey in 2020. It was carried out on May-505, a local cotton variety. The study examined the variation of seed yield, water use efficiency (WUE), and irrigation water use efficiency (IWUE) of cotton with different irrigation programs and water levels. The field trial, which was designed as two factors and three replications, was designed according to the randomized complete block trial design. Four different irrigation levels (IL) (100%, 67%, 33%, and 0%) and two different irrigation scheduling approaches (gravimetric and pan evaporation) were investigated in the study. Seasonal water use values in treatments varied between 215 (0%) and 746 (100% - Pan evaporation approach) mm during the production period. The average yield values obtained with irrigation levels, which have essential effects on cotton seed yield, are listed as follows; 2057 kg ha-1 (IL-0%), 3471 kg ha-1 (IL-33%), 3771 kg ha-1 (IL-67%), and 5083 kg ha-1 (IL-100%). It was determined pan evaporation applications performed higher yields than gravimetric applications. WUE values were between 0.63 – 1.04 kg m-3. The gravimetric method’s yield response factor (ky) was 0.73, and the pan evaporation method’s yield response factor (ky) was 0.89. These results show that cotton is tolerant of water stress. In conclusion, although the pan evaporation approach with 100% treatment is suggested for cotton production in the parts of the Aegean region within the semi-arid climate zone, while water resources are sufficient. When the results are evaluated in terms of seed cotton yield for a deficit irrigation strategy, IL-67% treatment with a gravimetric approach can be used.

The tadpoles of four amphibian species, namely the Marsh Frog (Pelophylax ridibundus), the Iranian Long-Legged Frog (Rana macrocnemis), the Caucasian Parsley Frog (Pelodytes caucasicus) and the Variable Green Toad (Bufotes variabilis), were exposed to acute concentrations (0 to 500 mg/L) of ammonium nitrate to assess the lethal effects (larval growth, abnormalities, mortality, and LC50 values). Eggs of each species were obtained from clean and polluted habitats in the same region and the tadpoles for experiments were provided from those eggs in the laboratory conditions. Although there was some variability between different populations of the same species or between different species in the observed effects, acute levels of ammonium nitrate caused decreased growth rate and increased abnormalities and mortality in general. Among the 4 amphibian species, the Variable Green Toad was the most damaged one in terms of growth reduction (on average 77-83%), and abnormality rates, and the most damaged one in terms of mortality rates was the Marsh Frog (on average 61-72%). Additionally, the species with the lowest concentration of ammonium nitrate, which killed half of its population, was the Marsh Frog. LC50 values for two populations of Marsh Frog were 37 and 59 mg/L. As a result of our research, it was determined that the acute fertilizer levels caused by agricultural activities in the region had very important harmful effects for all the species we examined. In this context, it can be said that very important environmental and biodiversity problems may occur if certain precautions are not taken regarding the use of the fertilizers and if the awareness of the farmers using these fertilizers cannot be raised.
