Şahin, Mehmet Kürşat; Çetintaş, Ortaç; Yanchukov, Alexey; Kurnaz, Muammer
The Lebanese Lizard (Phoenicolacerta laevis), primarily native to the Levant region, has recently been discovered in isolated populations well beyond its known distribution. This study presents the first confirmed record of P. laevis along the Black Sea coast of northern Türkiye, specifically in the city of Karadeniz Ereğli, Zonguldak Province. Mitochondrial cytochrome b (cyt b) sequence analyses revealed a high degree of genetic similarity (>99%) between the Karadeniz Ereğli specimens and those from both Andırın, Kahramanmaraş (within the species' native range in southern Türkiye) and Anaklia on Georgia's Black Sea coast, suggesting a shared origin. We propose that the presence of P. laevis in Karadeniz Ereğli is likely the result of human-mediated introduction, possibly via maritime trade, as the lizards were found restricted to the walls of a single building near a major port. A comparable introduction scenario has previously been suggested for the Anaklia population. The highly localized occurrence and absence of the species in neighboring areas indicate a recent introduction; however, the factors inhibiting further spread within the urban landscape remain unclear. This finding contributes to the broader understanding of species distribution dynamics and underscores the significant role of anthropogenic activity in facilitating the range expansion of non-native reptiles.

Faizin, Mu’Adil; Karimullah, Suud Sarim; Faizal, Bhismoadi Tri Wahyu; Lubis, Ihsan Helmi
With the growing number of publications on digital zakat, there is a pressing need for research on zakat management to develop general concepts that can serve as policy standards for zakat management practitioners and national zakat regulators. This research aims to provide insights into managing zakat in an easy, flexible, transparent, and targeted manner. The study employs field research methods, observing real events in society, and uses empirical legal research techniques with an interdisciplinary approach, incorporating sociological and ethnographic studies. The findings indicate that proper zakat distribution requires a deep understanding of its fiqh, grounded in shari'a texts and explored through both a linguistic approach (al-qowâid al-lughawiyyah) and an objective shari'a approach (maqâshid asy-syarî'ah). Furthermore, collecting zakat funds by national amil zakat agencies and institutions in Indonesia must adapt to contemporary times and technology, providing an alternative that facilitates muzakkī's in fulfilling their obligations.

Vaissi, Somaye; Kurnaz, Muammer; Şahin, Mehmet Kürşat; Hernandez, Axel
The degree to which closely related species conserve or diverge in their niche characteristics may provide insight into evolutionary and diversification processes, as well as some understanding of broad-scale biogeographic patterns. In this study, we used an ensemble of 10 algorithms to predict the distributions of 12 Ablepharus species in geographical (G)-space for the recent time and the future (2081–2100) climate conditions. Niche overlap, equivalency, and similarity tests in environmental (E)-space were used to test niche divergence and conservatism. The consensus model showed that temperature seasonality (n = 6) and annual precipitation (n = 3) were the major factors predicting the distribution of 75% (9 out of 12) of the species. The ensemble models based on ssp585 predict that 83.33% of the species (n = 10) may have contracted their ranges, especially at lower altitudes along their southern margins. They may have also expanded northward during this period. However, in the ssp126, most species’ distribution ranges may remain unchanged despite contractions and expansions. Based on multivariate niche analyses, the distributions of 28 and 11 paired comparisons explored in this study significantly diverged and conserved. We found that closely related species inhabit different habitats and respond to their climatic characteristics, indicating that ecology has a significant influence on speciation.

In this study, we re-examine the Darevskia parvula group comprehensively using morphology, osteology and mitochondrial phylogeny, and describe a new endemic species from Turkey: Darevskia tuniyevisp. nov. A total of 257 adult specimens were evaluated for external morphology (scalation and biometry) with univariate (descriptive statistics and ANOVA with post-hoc tests) and multivariate (Discriminant Analysis and ANOSIM) analyses. In parallel, osteological data and molecular analyses using three DNA markers (mitochondrial 16S rRNA and Cyt-b, nuclear Rag-1) were used to complete the description of the new taxon. The molecular phylogenetic analyses indicated that the D. parvula group is composed of three taxa as D. parvula, D. adjarica and D. tuniyevisp. nov., and showed that D. adjarica and D. tuniyevisp. nov. are reciprocal sister taxa. On the other hand, D. adjarica is morphologically very different from other two forms, while D. parvula is hardly distinguishable externally from D. tuniyevisp. nov. Therefore, we can consider that D. parvula and D. tuniyevisp. nov. are cryptic species. These two cryptic species retain their primitive morphology within the group, while D. adjarica has changed, perhaps due to different bioclimatic conditions in its Pleistocene refuge and current area.

Halil İbrahim Şen
İktisat ile ilgili tanımlama yapılırken genelde "ihtiyaçların sonsuz, kaynakların ise sonlu" olduğundan söz edilir. Bu nedenle verimlilik hayatın her noktasında fazlaca riayet edilmesi gereken düsturlardan olmuştur. Bazen üretim enstrümanlarında ya da diğer tüm değişkenlerde herhangi bir değişiklik yapmadan sadece verimlilikle ilgili çalışma yapılarak aynı kaynakla daha fazla ihtiyaç karşılanabilir. Aynı ihtiyacı daha az kaynakla gidermek te bahsedilen duruma farklı açıdan bir örnektir. Bu bağlamda bir örnek teşkil edebilecek Tez çalışmamızda, çalışmaya konu olan ihtiyaç yine karşılanmış ama hem sorumluluk konusunda eşit dağıtım yapılarak adalet sağlanmış hem de aynı iş daha az kaynakla tamamlanmıştır. Çalışmamızın ikinci kısmında Doğrusal Programlama üçüncü kısmında ise Ulaştırma Modeli hakkında geniş malumat verildikten sonra üçüncü kısımda anlatılan yöntem probleme uygulanmıştır. Problemin çözümü aşamasında optimal çözüme ulaşmak için WINQSB paket programı kullanılmıştır. Elde edilen sonuçlara göre aynı iş için harcanan kaynak miktarında %12'lik bir iyileşme ile beraber işlerin daha organize ve hızlı şekilde yürümesini sağlayacak bir dağıtım tesis edilmiştir.
