Despite the damaging effects of pesticides glyphosate (Gly), atrazine (Atra) and fipronil (Fip)
on different organisms, the mutagenic, genotoxic and morphotoxic potential of testudine …

Although the toxicity of zinc oxide (ZnO) nanoparticles (NPs) is known in several
experimental models, little is known about their effects on bird representatives. Therefore …

The size and shape of red blood cells (erythrocytes) is determined by key life history
strategies in vertebrates. They have a fundamental role to deliver oxygen to tissues, and …

In this study, basic erythrocyte sizes in P. ridibundus individuals inhabiting a polluted area
(heavy metals, nitrates, nitrites, and ammonium) in southern Bulgaria were evaluated. The …

Blood oxygen‐carrying capacity is shaped both by the ambient oxygen availability as well as
species‐specific oxygen demand. Erythrocytes are a critical part of oxygen transport and …

Hematology is a simple but reliable method to determine the influence of environmental
stressors on the physiology and performance of teleost fish. Understanding the detailed …

In eukaryotes, the cell has the ability to modulate the size of the nucleus depending on the
surrounding environment, to enable nuclear functions such as DNA replication and …

Background Endurance flight impose substantial oxidative costs on the avian oxygen
delivery system. In particular, the accumulation of irreversible damage in red blood cells can …

Small erythrocytes might be beneficial for blood rheology, as they contribute less to blood
viscosity than large erythrocytes. We predicted that rheological disadvantages of larger …

The birds inhabiting the high-altitude mountains have several physiological adaptations to
environmental conditions. In this study, we try to investigate if are the morphological …
