Sperm Human Biobanking: An Overview.

The purpose of this article is to analyze in detail the advantages and disadvantages of sperm cryopreservation, focusing on the cellular and molecular changes that occur during these processes. The main issue is the cellular damage caused by ice crystal formation and osmotic imbalance, along with other secondary effects such as sperm motility and viability, as well as the acrosome reaction or oxidative stress. Another important aspect is the examination of how chromatin structure and DNA integrity affect sperm.

Tectonic extension and paleoelevation influence mammalian diversity dynamics in the Basin and Range Province of western North America.

Landscape properties have a profound influence on the diversity and distribution of biota, with present-day biodiversity hot spots occurring in topographically complex regions globally. Complex topography is created by tectonic processes and further shaped by interactions between climate and land-surface processes. These processes enrich diversity at the regional scale by promoting speciation and accommodating increased species richness along strong environmental gradients.

Information Flow between Parents and Offspring Is Essential for Successful Development.

Over the last several decades, the sciences of developmental biology and physiology have expanded and intertwined their scope enormously [...

Biobanks, offspring fitness and the influence of developmental plasticity in conservation biology.

Mitigation of the widely known threats to the world's biodiversity is difficult, despite the strategies and actions proposed by international agreements such as the United Nations Framework Convention on Climate Change (UNFCCC) and the Convention on Biological Diversity (CBD). Nevertheless, many scientists devote their time and effort to finding and implementing various solutions to the problem. One potential way forward that is gaining popularity involves the establishment of biobank programs aimed at preserving and storing germplasm from threatened species, and then using it to support the future viability and health of threatened populations.
