pollination biologyDyckia is the third most diverse genus from Pitcairnoideae, pollinated mainly by insects and hummingbirds. In this study, we evaluated demography, reproductive biology and pollination of Dyckia excelsa, a saxicolous species typical of ironstone outcrops. It occurs in groupings ...
Pathologic eggs have been documented in the amniote eggs of birds, turtles, and dinosaurs. These eggs occur either in the form of one egg within another egg, a condition known as ovum-in-ovo or multi-shelled eggs showing additional pathological eggshell
In spite of the fact that this is an endangered species, very little is known about the biology of the pampas deer. Moreover, most information has not been published in peer-reviewed scientific journals, and is only available in local publications, theses, etc. Therefore, our aim was to up...
Biology Instructor Stephen Reinbold has a PhD in Biological Sciences and a strong passion for teaching. He taught various subjects including General Biology, Environmental Science, Zoology, Genetics, and Anatomy & Physiology at Metropolitan Community College in Kansas City, Missouri, for nearly thirty ...
The changes of biology during different estrus cycle. Estrogen and progesterone are secreted via the ovary or uterus and undergo changes during the estrus cycle. In addition, the basal body temperature also changes, while the thickness of the endometrium has corresponding transformations. After menstrua...
Although several studies are beginning to uncover the details of the reproductive biology in this plant [23, 24], much is still unknown. Olive pollination is mainly anemophilous. Paternity tests have revealed a certain degree of self-incompatibility (SI) in several olive cultivars [25, 26]. ...
Further, the settlement of D. cylindrus larvae in the laboratory now makes out-planting for restoration more feasible. Asynchronous spawning times and rapid embryonic development may have important consequences for population biology, connectivity, and management, by affecting fertilization dynamics and ...
This may be in terms of natural fertility (47), or to detect such things as CatSper mutations that may affect medically assisted reproduction outcomes (48), without the requirement for complex technology such as calcium imaging or molecular biology. A key issue for fixed assays, such as ...
