Neurophysins are a group of proteins that are associated with the transport and storage of neuropeptides, specifically oxytocin and vasopressin. They are highly concentrated in the posterior pituitary gland, where these neuropeptides are secreted into the bloodstream. Neurophysins are synthesized in the hypothalamus as part of larger precursor proteins called neurophysin-oxytocin and neurophysin-vasopressin.
Pink algae generally refer to certain types of algae that have a pink or reddish pigmentation, often due to the presence of pigments like phycoerythrin and carotenoids. The term "pink algae" is often used informally and can refer to various types of algae, including certain species of cyanobacteria (often called blue-green algae) and red algae.
Diatoms are a type of single-celled algae, classified within the group known as phytoplankton. They are particularly significant in aquatic ecosystems, playing a vital role in the food web and contributing to primary production. Diatoms have unique silica-based cell walls known as frustules, which have a distinctive geometric structure. These organisms are found in both marine and freshwater environments and are capable of photosynthesis, using sunlight to convert carbon dioxide and water into energy.
Ichthyoplankton refers to the early life stages of fish that are found in the plankton community of marine and freshwater ecosystems. This group primarily includes fish eggs and larval fish, which drift in the water column and are crucial components of aquatic food webs. Ichthyoplankton plays an important role in the ecology of aquatic systems as they serve as prey for a variety of larger organisms, including other fish, invertebrates, and birds.
The Center for Microbial Oceanography: Research and Education (C-MORE) is a research and educational initiative that focuses on the study of microbial life in the ocean and its impact on marine ecosystems and global biogeochemical cycles. Established with the aim of advancing our understanding of the role that microbes play in oceanic processes, C-MORE conducts interdisciplinary research that combines microbiology, oceanography, and environmental science.
The continental shelf pump is a physical oceanographic mechanism that describes how water is transported from the continental shelf to the open ocean. This process primarily occurs due to the interplay of wind forces, water density differences, and the topography of the seabed. Here’s how it works: 1. **Wind Stress**: Winds blowing across the surface of the ocean can create surface currents.
A biological system refers to a complex network of biologically relevant components that interact with one another in a way that contributes to the functioning of a living organism or an ecological environment. Biological systems can be studied at various levels, from cellular and molecular levels to whole organisms and ecosystems.
Iodine is a chemical element with the symbol **I** and atomic number 53. In biology, iodine is an essential trace element that plays a crucial role in the synthesis of thyroid hormones, which are critical for various physiological processes, including metabolism, growth, and development.
As of my last knowledge update in October 2021, "Ian Ford" may refer to various individuals or entities, depending on the context. There isn't a widely recognized figure or concept universally associated with the name. It's possible that he could be a private individual, a professional in a specific field, an author, or someone involved in a particular event or organization.
Ira Longini is a prominent biostatistician and researcher known for his work in the fields of epidemiology and statistical modeling. He is particularly noted for his contributions to the modeling of infectious diseases, vaccine efficacy, and the dynamics of disease transmission. Longini has collaborated on various studies related to public health, including research on the spread of influenza and other infectious diseases, as well as the impact of vaccination strategies.
James Johnstone is a biologist known for his contributions to the field of evolutionary biology and ecology. His research often focuses on the evolution of social behaviors and mating strategies in animal populations. He has published various studies that explore the mechanisms behind natural selection and the ecological factors that influence species interactions. In addition to his research, Johnstone may also be involved in teaching and mentoring students in biological sciences.
Microbiology of oxygen minimum zones (OMZs) refers to the study of microbial communities and their activities in areas of the ocean where oxygen levels are significantly reduced compared to surrounding waters. These zones can occur at various depths in the ocean, typically located between 200 and 1,000 meters, and are characterized by low concentrations of dissolved oxygen (often less than 0.5 mL/L or 22 μM).
Marine ecoregions are distinct geographic areas of the ocean that have relatively homogenous ecological characteristics, including specific types of marine life, habitats, and environmental conditions. These ecoregions are often defined by factors such as water temperature, salinity, depth, and the physical features of the seabed, as well as biotic components like species composition and community structure.
A marine ecosystem is a complex network of living organisms and their physical environment found in the ocean and other saltwater bodies. It includes various habitats such as coral reefs, mangroves, estuaries, open oceans, and coastal areas. Marine ecosystems are characterized by their diverse range of organisms, including fish, marine mammals, invertebrates, algae, and other microorganisms.
Marine microorganisms are tiny living organisms found in ocean and sea environments. They are typically microscopic in size and include a wide variety of life forms, such as bacteria, archaea, viruses, phytoplankton, and zooplankton. These microorganisms play crucial roles in marine ecosystems and are vital for the health of our planet. Here are some key aspects of marine microorganisms: 1. **Bacteria and Archaea**: These are prokaryotic microorganisms that thrive in diverse marine environments.
Marine protists are a diverse group of eukaryotic microorganisms that inhabit marine environments. They are primarily single-celled organisms, although some can form multicellular structures. Marine protists play crucial roles in aquatic ecosystems, functioning as key components of the food web and contributing to nutrient cycling.
Ocean acidification refers to the process by which the pH levels of seawater decrease due to the absorption of carbon dioxide (CO2) from the atmosphere. In the context of the Arctic Ocean, this phenomenon is particularly concerning due to several factors that make the region vulnerable to changes in water chemistry.
Pennales is a term that refers to a group of diatoms, a class of microalgae known for their siliceous cell walls. Diatoms are unicellular organisms that play a significant role in aquatic ecosystems, serving as primary producers and forming the base of the food web. The term "Pennales" is often used to categorize the pennate diatoms, which are primarily characterized by their elongated shape and bilateral symmetry.
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
