Climate Characteristics of Special Nature Reserve „Obedska Bara“(Serbia)

Abstract

Special Nature Reserve Obedska Bara has moderately continental climate,
characterized by slightly cold and conservative climate, which is manifested through the following
physiological sensation of heat: cold, very fresh, comfortable and weakly sultry. Essential climatic
characteristics exert as abiotic climatic factors on wildlife. Air temperature affects the growing season,
the types of vegetation present and wetland primary productivity. Air pressure impacts on animal
activity. Wind influences on subjective temperature sensation and in plants on transpiration,
reproduction and distribution. High humidity impedes insects in flight, forces frogs to leave ponds,
contributes propagation in some plants and asphyxiates others. High insolation causes germination and
foliation and awaking from hibernation of mammals, reptiles and amphibians, while low insolation
forces animals to take shelter in hiding places. Under wet – dry cycles, species are frequently annual,
and are destroyed either when the wetland dries (submerged species), or when it is re – inundated
(emergent species).
