REPRODUCTIVE BIOLOGY OF THE SADDLE CICHLID, AEQUIDENS TETRAMERUS (HECKEL, 1840) (CICHLIFORMES: CICHLIDAE), IN SMALL FOREST STREAMS IN THE MACHADO RIVER BASIN, SOUTHWESTERN AMAZONIA

The aim Digestive Aids of this study was to evaluate the reproductive strategy of Aequidens tetramerus in small streams of the Machado river basin, southwestern Amazon.We collected samples in two streams using seine and dip nets along a 50-m stretch of the stream.We collected 86 Hat fishes, 19 males and 67 females (sex-ratio, 3.52 female:1male).The

In this study, we aimed to introduce two different generalizations of the soft prime int-ideal and clarify the relationships between the soft prime int-ideal and the substructures of a ring.First, we explored new algebraic features of the soft prime int-ideal.We defined and exemplified essential concepts such as soft nilpotent elements, soft idempo

Water transport across the cell membranes is regulated largely by a family of proteins known as aquaporins (AQPs).Plasma membrane intrinsic protein (PIP) is an important subfamily of plant AQPs localized on the plasma membrane.To investigate the molecular mechanism of water regulation in seed germination, seven genes encoding PIP were initially clo

We describe a new mechanistic bio-economic model for simulating the spread of Mycobacterium avium ssp.paratuberculosis (MAP) within a dairy cattle herd.The model includes age-dependent susceptibility for infection; age-dependent sensitivity for detection; environmental MAP build-up in five separate areas of the farm; in utero infection; infection v
