Decomposition, vegetation regeneration, and biological control are essential ecosystem functions, and animals are involved in the underlying processes, such as dung removal, seed removal, herbivory, and predation. Despite evidence for declines of animal diversity and abundance due to climate change and land-use intensification, we poorly understand how animal-mediated processes respond to these global change drivers. We experimentally measured rates of four ecosystem processes in 134 grassland and 149 forest plots in Germany and tested their response to climatic conditions and land-use intensity, that is, grazing, mowing, and fertilization in grasslands and the proportion of harvested wood, non-natural trees, and deadwood origin in forests. For both climate and land use, we distinguished between short-term effects during the survey period and medium-term effects during the preceding years. Forests had significantly higher process rates than grasslands. In grasslands, the climatic effects on the process rates were similar or stronger than land-use effects, except for predation; land-use intensity negatively affected several process rates. In forests, the land-use effects were more pronounced than the climatic effects on all processes except for predation. The proportion of non-natural trees had the greatest impact on the process rates in forests. The proportion of harvested wood had negative effects, whereas the proportion of anthropogenic deadwood had positive effects on some processes. The effects of climatic conditions and land-use intensity on process rates mirror climatic and habitat effects on animal abundance, activity, and resource quality. Our study demonstrates that land-use changes and interventions affecting climatic conditions will have substantial impacts on animal-mediated ecosystem processes.

Başer, Begüm; Yetiş, Ülkü; Yousaf, Balal; Department of Environmental Engineering (2021-9-10)
Phorate is one of the widely used organophosphorus pesticides (OPPs) having detrimental impacts on living creatures and the environment. As such, biochar is a low-cost and environment-friendly material that can be used as a catalyst to develop the strategic tools that reduce and overcome the challenges caused by their rising concentration. Herein, phorate removal strength of potassium hydroxide and ureamodified sewage sludge-derived biochars were described for the most goal-oriented technique. The advanced ...
Ecosystem indicators-accounting for variability in species' trophic levels

Trophic level (TL)-based indicators are commonly used to track the ecosystem effects of fishing as the selective removal of organisms from the food web may result in changes to the trophic structure of marine ecosystems. The use of a fixed TL per species in the calculation of TL-based indicators has been questioned, given that species' TLs vary with ontogeny, as well as over time and space. We conducted a model-based assessment of the performance of fixed TL-based indicators vs. variable TL-based indicators...
Productivity Analyses in Fermentations with Three Different Biolarvacides
Özçelik, Hayriye; Özcengiz, Gülay; Department of Biotechnology (2004)
The development of insecticides resistance among many insect species and the ecological damage occasionally caused by the lack of specificity in the toxic effects of insecticides have provided the impetus to seek alternative methods of insect control. This observation led to the development of bioinsecticides based on the insecticidal action Bacillus sphaericus (Bs), Bacillus turingiensis (Bt). The discovery of biolarvicidal actions of Bacillus thuringiensis and Bacillus sphaericus opened a new perspective ...
Warming Effects on Periphyton Community and Abundance in Different Seasons Are Influenced by Nutrient State and Plant Type: A Shallow Lake Mesocosm Study

Periphyton plays an important role in lake ecosystems processes, especially at low and intermediate nutrient levels where periphyton contribution to primary production can be similar to or exceed that of phytoplankton. Knowledge of how periphyton responds to key drivers such as climate change and nutrient enrichment is, therefore, crucial. We conducted a series of mesocosm experiments over four seasons to elucidate the responses of periphyton communities to nutrient (low and high, TN-0.33 mg L-1 TP-7.1 mu g...
BIODIVERSITY ASSESSMENT OF FISHES AND INVERTEBRATES IN MERSIN BAY, THE EASTERN MEDITERRANEAN SEA, BY USING DNA BARCODING
Çiftçi, Ozan; Kıdeyş , Ahmet Erkan; Department of Marine Biology and Fisheries (2016-9-25)
Cataloguing the biodiversity of marine ecosystems is critical for several implications: e.g. protecting species under threat, detecting alien species or ecosystem based management etc. The eastern Mediterranean Sea is a hot spot for bioinvasion, however its biodiversity had been poorly studied. In the view of the ongoing changes in the Mediterranean, fish and invertebrate biodiversity of Mersin Bay were evaluated in this study by using DNA barcoding techniques, based on the mitochondrial cytochrome oxidase ...
