A marine aquarium is an aquarium that keeps marine plants and animals in a contained environment. Fish only tanks often showcase large or aggressive marine fish species and generally rely on mechanical and chemical filtration. FOWLR and reef tanks use live rock , a material composed of coral skeletons harboring beneficial nitrogen waste metabolizing bacteria, as a means of more natural biological filtration. Marine fishkeeping is different from its freshwater counterpart because of the fundamental differences in the constitution of saltwater and the resulting differences in the adaptation of its inhabitants. A stable marine aquarium requires more equipment than freshwater systems, and generally requires more stringent water quality monitoring.

The Art of Aquarium Keeping Communicates Science and Conservation

Sharks are magnificent animals and an exciting group of fishes. As a group, sharks, rays, and skates belong to the biological taxonomic class called Chondrichthyes, or cartilaginous fishes elasmobranchs. The entire supporting structure of these fish is composed primarily of cartilage rather than bone. There are some described species of sharks, which come in all different sizes from the foot-long whale shark Rhincodon typus to the 2-foot-long marble catshark Atelomycterus macleayi. Although sharks have been kept in public aquariums since the s, advances in marine aquarium systems technology and increased understanding of shark biology and husbandry now allow hobbyists to maintain and enjoy sharks in their home aquariums, and they are becoming increasingly popular as pet animals. The proper care and display of sharks requires great attention to details. The following information is intended for use by home aquarists and those working in small public aquaria.

Aquarium Corals: Selection, Husbandry, and Natural History

In technology-driven societies, scientists, and educators alike flounder in making science interesting and applicable. Communicating science, defined as communicating scientific facts as well as teaching and using the scientific process, can also be done informally though leisure activities. In this qualitative study, I examined the leisure activity of aquarium keeping and its ability to communicate relative aquatic facts and processes. This study examined aquarium keepers across the United States via interviews, participant observation, and an ongoing analysis of aquarium hobby literature. Thus, this study indicates 1 caring for a home aquarium communicates science latently, 2 over time, latent science communication becomes activated, and 3 long-term aquarium keeping leads to a personal response in science, as well as conservation. In addition, artistic expression and innovation intersect with scientific knowledge and application to create beautiful, biodiverse, ecosystems. Through the process of successfully maintaining an aquarium, continued participation leads to a proficiency in applicable scientific facts, a better understanding of scientific processes, and an improved conservation ethic for aquatic resources.

Metrics details. The Caribbean pillar coral Dendrogyra cylindrus was recently listed as a threatened species under the United States Endangered Species Act. One of the major threats to this species is its low, virtually undetectable recruitment rate. Until recently, the reproductive behavior of D. We collected gametes from spawning individuals on three occasions and attempted to rear larvae and primary polyp settlers. Here we describe successful fertilization methods for D.

Шаги неумолимо приближались. В голове у него не было ни единой мысли - полная пустота. Он не знал ни где он находится, ни кто его преследует и мчался, подгоняемый инстинктом самосохранения.

Согласно словам офицера, который отвел Дэвида в морг, некий канадский турист сегодня утром в панике позвонил в полицию и сказал, что у одного японца в парке случился сердечный приступ. Прибыв на место, офицер увидел мертвого Танкадо, рядом с которым находился упомянутый канадец, и тут же по рации вызвал скорую. Когда санитары отвезли тело Танкадо в морг, офицер попытался расспросить канадца о том, что произошло. Единственное, что он понял из его сбивчивого рассказа, - это что перед смертью Танкадо отдал кольцо.

 В ТРАНСТЕКСТЕ сбой. - ТРАНСТЕКСТ в полном порядке. - Вирус. - Никакого вируса. Выслушай меня внимательно, - попросил Стратмор.

Хотя, быть может, подумал Халохот, Беккер не видел, как он вошел в башню. Это означало, что на его, Халохота, стороне фактор внезапности, хотя вряд ли он в этом так уж нуждается, у него и так все козыри на руках. Ему на руку была даже конструкция башни: лестница выходила на видовую площадку с юго-западной стороны, и Халохот мог стрелять напрямую с любой точки, не оставляя Беккеру возможности оказаться у него за спиной, В довершение всего Халохот двигался от темноты к свету. Расстрельная камера, мысленно усмехнулся .

Покойный лежал на спине, лицом вверх, освещаемый лампами дневного света, вроде бы ничего не скрывая. Беккер непроизвольно снова и снова вглядывался в его странно деформированные руки.

    We previously showed that an unintentionally introduced zoanthid in a home aquarium contained high concentrations of palytoxin and was likely responsible for a severe respiratory reaction when an individual attempted to eliminate the contaminant colonies using boiling water.

    Many of the following Husbandry Manuals are available from one or more of the regional Zoo Management Associations; unfortunately in most cases you need to be a financial member of the relevant Association in order to be eligible to obtain a copy of a Manual.
