In this study, anatomical and polynological features of Eranthis hyemalis (L.) Salisb. were investigated. For palynological analysis of plant materials, pollen preparations of each taxon were prepared for light microscopy research according to the Wodehouse and Erdtman methods and measurement of the morphological characters of pollen were carried out. For anatomical investigation, transverse sections of root, stem and leaf have been taken from E. hyemalis by scapel. All sections examined by light microscope. In the cross sections of the root, the pith was completely covered by xylem cells. In contrast to this, the pith of the stems is hollow. Leaves have amaryllis type of stomata. They are mesomorphic. The results of the light microscope investigation revealed that the pollen grains of E. hyemalis are tricolpate and exine scabrate. We believe that findings of this study will make contributions to the biodiversity and taxonomy in future.

There are 44 dams and ponds which are both artificial and naturally occurring within the borders of Eskiþehir. In addition, there are 58 rivers in total. In addition to these, Balýk Damý Wetland, which is a Natural Site and which has occurred as a result of the floods of Sakarya River, is also located.
These aquatic ecosystems are used to as a resting area during migration are as host to many species. It also hosts many endemic species. These endemic species include both invertebrate and vertebrate species.
For this reason, hunting is prohibited in the regions where endemic species are located and the researches are subject to permission.
These aquatic ecosystems are also used for eco-tourism purposes.
This study contributes to Turkey aquatic ecosystems; aquatic ecosystems better recognition of our country will be ensured.

According to the research area is located within the grid system used in Turkey's flora B2 square. In the studies carried out in 2018, 283 species and subspecies taxa were identified in the research area and its vicinity. 11 of these species are endemic and endemism rate is 3.9%. The distribution of species to floristic regions is as follows; 11% is European Siberia, 7% is Mediterranean and 11% is Iran-Turan. The remaining group of 71% is group of plants that can be found in more than one phytogeographic region or whose phytogeographic region is not certain. When the region of the study area is evaluated from this point of view, the rate of endemism is lower than the other parts of our country. Floristic data obtained as a result of the studies confirmed this situation. All of the endemic plants identified in the region are classified according to the IUCN categories and all of these plants are in the LR (Ic) category. In other words, the population levels of endemic plant taxa, which are determined to be distributed in the study area, are currently not under threat.

Evrimsel ve sistematik iliþkilerin daha verimli olarak ortaya konulabilmesi için bitkilerin biyolojik özelliklerinin, polen morfolojisi çalýþmalarýyla desteklenmesi düþüncesi bizi bu çalýþmaya yönlendiren etmenlerden biridir. Bu kapsamda, çalýþmamýzda Türkiye’de doðal yayýlýþ gösteren Euphorbiaceae familyasýna ait iki Euphorbia taksonun palinolojik özelliklerinin saptanmasý amaç edinilmiþtir. Polen Morfolojisi çalýþmalarýnda, yapýlan arazi çalýþmalarý esnasýnda toplanan bazý Euphorbiaceae taksonlarýna ait örneklerden (Euphorbia macroclada Boiss., Euphorbia erythrodon Boiss. & Heldr.) Wodehouse ve Erdtman yöntemlerine göre her bir takson için en az 5’er tane olmak üzere polen preparatlarý hazýrlanmýþtýr. Araþtýrma bitkilerinin palinolojik özelliklerinin belirlenmesi için Iþýk Mikroskobunda inceleme ve ölçüm yapýlarak, morfometrik sonuçlarý ortaya konulmuþtur. Taramalý elektron mikroskobu ve ýþýk mikroskobu ile gerçekleþtirilen polen morfolojisi çalýþmalarýnda, incelenen Euphorbia taksonlarýnýn trikolporat tipte ve prolate-sferoidal þekilli olduklarý, rugulat-perforat bir ornemantasyon gösterdikleri bulunmuþtur.

Bu çalýþma ile G. sakaryaensis’in Seydisuyunda yayýlýþ gösteren popülasyonlarýnýn bazý biyolojik özelliklerinin belirlenmesi amaçlanmýþtýr. Bu amaçla Mart 2016-Nisan 2017 tarihleri arasýnda farklý zamanlarda yapýlan örneklemelerle elde edilen bireylerin incelemesi yapýlmýþtýr. Ýdrisyayla, Akin ve Kümbet ve Barajlar sonrasý bölgelerinden elde edilen bireylerin Morfometrik-Meristik ve Boy-Aðýrlýk iliþkisi ortaya konmuþtur. Morfometrik ölçümler diskriminant analiz (LDA) ve Temel Öðeler Analizi (PCA) yapýlarak deðerlendirme yapýlmýþtýr. Balýklarýn boy-aðýrlýklarý hesaplanmýþ % 95 güven limiti aralýðýnda b deðeri en düþük 3,35 en yüksek 3,59 ortalama 3,47 olarak tespit edilmiþ ve pozitif allometrik büyüme gösterdikleri tespit edilmiþtir.
