Changes in Abundance and Distribution of Humboldt Penguin Spheniscus Humboldti
At an intraspecific level, patterns of species abundance distribution (SAD) vary in space and time, especially over the largest scales. The most basic, unimodal pattern is expressed in a log-normal shape, based on the abundant-center hypothesis (Gaston et al. 2008). SAD patterns can be driven by environmental variables (e.g. temperature, salinity, precipitation, productivity) as well as intrins...
متن کاملSperm Characteristics in Cryopreserved Buffalo Bull Semen and Field Fertility
Semen quality and its relationship to fertility are major concern in animal production. The aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through Artificial Insemination(AI). Semen samples were collected from four buffalo bulls. Semen volume and sperm concentration appeared to be significantly different (P0...
متن کاملPellet cryopreservation for chicken semen: effects of sperm working concentration, cryoprotectant concentration, and equilibration time during in vitro processing.
The aim of the study was to standardize the pellet cryopreservation procedure for chicken semen. Mericanel della Brianza male chicken breeders (Italian breed) were used. Pooled semen samples were processed according to the following conditions: (1) dilution in prefreezing extender to 1 versus 1.5 bill cells/mL sperm working concentration (SWC); (2) 6% versus 9% dimethyl acetamide (DMA) concentr...
متن کاملHuman sperm volume regulation. Response to physiological changes in osmolality, channel blockers and potential sperm osmolytes.
BACKGROUND Volume regulation is an important sperm function because defective sperm cannot negotiate the female tract in an infertile mouse model and swollen human sperm cannot penetrate and migrate through mucus. METHODS AND RESULTS The size of sperm from 52 donor ejaculates incubated in medium of female tract fluid osmolality (BWW290) was measured by flow cytometry to be identical to that i...
متن کاملSemen quality and age-dependent changes among male participants with normal sperm count in Qom, Iran
Background: One of the most conventional causes of male infertility is increasing age, which has significant effects on sperm physiology. In advanced ages, degenerative alterations in germinal epithelium, decreased number of Leydig cells, and their functions affect spermatogenesis through a decrease in testosterone level. So it is important to know whether advanced paternal age is associated wi...
