Annual Change of the Hematological Parameters in Female White Goats

2025-12-15T14:07:34+03:00

In this study, hematological parameters changes in female goats were observed. It has been shown that a decrease in the level of erythrocyte (RBC), Hematocric (Htc) and Hemoglobin (Hb) in higher temperature conditions was statistically different from an increase in the level of these characters in lower temperature conditions (P<0.01). Monthly changes in level of Leukocyte, lymphocyte, granulocyte and monocyte were statistically different (P<0.01). Moreover, increase in level of WBC, granulocyte and monocyte in higher temperatures and a decrease in level of lymphocyte were detected. The effects of seasonal changes (temperature) on Thrombocyte (THR) values were significant and reached higher measurements during warmer months. Reductions in the level of RBC, Htc, Hb and THR values in months with a higher temperature can be considered as a result of the elevations of blood plasma volume. Rise in values of WBC, Gra and Mon in months with a higher temperature might be related with immunologic regulation and effects of physiological periods.

A Study on Ornithofauna of the Bulanık Plain (Muş)

2025-12-12T10:21:17+03:00

This study investigated bird species found in Bulanık Plain and its surrounding areas. As a methodological Dobinson's point and line transect methods were used to count the birds. Observations conducted over the course of a year resulted in the identification of 41 families belonging to 19 orders and 172 bird species. According to the results of the study, 34.30% (n=59) of the identified species were resident, 43.03% (n=74) were migratory, 12.20% (n=21) were winter visitors, and 10.47% (n=18) were transit migrants. According to Red Data Book lists; 13 species were classified as A.1.2, 39 species as A.2, 45 species as A.3, 18 species as A.3.1, 16 species as A.4, 24 species as A.5, 2 species as A.6, 1 species were classified as B.2, 7 species as B.3, 2 species as B.3.1, 2 species as B.4, 2 species as B.5, and 1 species as B.6. According to IUCN criteria, 1 species were classified as EN, 7 species as NT, 3 species as VU, and 161 species as LC.

Changes in Blood Serum Aldosterone Hormone and Some Mineral Levels in Lipopolysaccharide-Induced Hypothermic Rats

2025-12-12T10:36:59+03:00

In this study, we induced hypothermia in rats by administering LPS (Serotype E. coli: O111:B4; 250 µg/kg, ip). Blood samples were taken via intracardiac puncture at the entrance, deepest point, and exit of the induced hypothermia. In the control group, saline (0.09% NaCl, 0.5 ml/kg ip) was administered to rats, and blood samples were taken at the entrance, deepest point, and exit of hypothermia. It was determined that the administered LPS doses did not change the levels of aldosterone and Na, K, Cl, Ca, and P. As a result of the applications, the deepest point of hypothermia (ΔT: -1.48±0.09 ºC) was reached in an average of 104.46±4.32 minutes. Analysis of blood serum samples revealed that the differences in aldosterone, Na, K, Cl, Ca, and P levels between the LPS-induced hypothermia groups (entry, trough, and exit) compared to the control group were statistically insignificant. Our results indicate that LPS can cause thermoregulatory hypothermia accompanied by fever in rodents.

A Study on Ornıthofauna of the Saray Kaz Lake (Van)

2025-12-15T12:13:37+03:00

In the present study the bird species living in the Saray Kaz Lake were investigated. Dobinson’s point and line transect methods were used for counting of birds.

116 species belonging to 33 families were identified during about a year of observation period. These species were classified as follows 32.76 % (38) resident, 49.14 % (57) migratory, 8.62 % (16) winter visitor and 9.48 % (11) transit migratory species. According to the Red Data Book, 11 species are in A.1.2, 23 species were in A.2, 26 species were in A.3, 17 species were in A.3.1, 12 species were in A.4, 20 species were in A.5, 1 species were in B.2, 2 species were in B.3.1,2 species were in B3,2 species were in B4 status. According to the IUCN criteria, 2 species were determined to be in EN, 6 species in NT, 3 species in VU and 105 species in LC status.

Urbanization and Bird Nesting Behavior: A Bibliometric Review of Research Trends and Themes (1989–2024)

2025-12-17T13:33:45+03:00

Urbanization alters habitat structure, resource availability, and exposure to anthropogenic stressors, with direct implications for bird nesting behavior and breeding success. To characterize how this topic has been studied and to identify major research themes and gaps, we conducted a bibliometric review of Scopus-indexed publications on urbanization and bird nesting behavior. Using a structured search strategy and eligibility screening, 170 documents published between 1989 and 2024 were retrieved (records from 2025 were excluded to avoid partial-year bias) and analyzed using Bibliometrix (R) and VOSviewer. Publication output increased markedly after the mid-2010s, with the United States, China, Spain, Australia, and Brazil emerging as the most productive countries. Keyword co-occurrence and content mapping revealed six dominant themes: (i) urbanization and urban ecology, (ii) nesting behavior and predation, (iii) climate and environmental change, (iv) anthropogenic impacts and adaptation, (v) reproductive ecology and parasitism, and (vi) research methods and conservation approaches. The literature is taxonomically skewed toward Passeriformes, with frequent attention to magpies, great tits, and house sparrows, while other synanthropic taxa (e.g., Hirundo rustica, Delichon urbicum, Corvus monedula, and Corvus frugilegus) are also represented but less frequently. Recent studies increasingly address artificial light at night, noise, anthropogenic nest materials, and green infrastructure, indicating a shift toward more applied and mechanistic questions. Author productivity exhibited a Lotka-type pattern, suggesting a dispersed contributor base. Overall, the field is expanding but remains geographically and taxonomically uneven; future work should extend to underrepresented regions and non-passerine taxa and emphasize standardized metrics of nesting success and urbanization intensity.
