The inventory system is composed of sample holding boxes and the boxes are stored in freezers of various types depending on the sample storage requirements. (iv) Distribution is the process of retrieving one or more samples from the biorepository inventory system.
A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are stored, ideally they remain equivalent to freshly-collected ...
Due to storage constraints, approximately 5.5 million specimens from two walk-in freezers were placed into "high-density" configuration in 2006, and additional reconfiguration may be required. The current operations contract calls for the contractor to "adjust the storage configurations of specimens in one or more freezers to accommodate high ...
Seeds are often considered as an important delivery system of genetic information. Cryopreservation of recalcitrant seed is the hardest due to intolerance to low temperature and low water content. [52] However, plant vitrification solution can solve the problem and help recalcitrant seed (Nymphaea caerulea) cryopreserve. [53]
A consequence of deforestation is typically large-scale erosion, loss of soil nutrients and sometimes total desertification. Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil.
Erosion control is the practice of preventing or controlling wind or water erosion in agriculture, land development, coastal areas, river banks and construction. Effective erosion controls handle surface runoff and are important techniques in preventing water pollution , soil loss , wildlife habitat loss and human property loss.
Researching the collections of insects provides important information that develops knowledge about ecology, human health and crops. [4] Well-kept records aid the researcher in identifying whether there are differences in an observed specimen because of damages, treatments or deterioration.
Genetic diversity is often lost within captive populations due to the founder effect and subsequent small population sizes. [10] Minimizing the loss of genetic diversity within the captive population is an important component of ex situ conservation and is critical for successful reintroductions and the long term success of the species, since ...
