The books described marine glycoconjugates. Two articles concern microalgal metabolites such as steroid and sphingoid glycoconjugates, and a glycoprotein from a sea cucumber with interesting biological activities, respectively. One article discusses the fatty acid composition and thermotropic behavior of glycolipids and other membrane lipids of green macrophyte Ulva lactuca. Three articles cover lectin subjects. One review article analyzes perspectives of marine and freshwater lectins’ application in experimental oncology and the therapy of oncological diseases; another article describes the use of a sponge lectin in the construction of a recombinant virus. The third article concerns the function of the immunity of a lectin in producing this compound crinoid. Two articles concern steroid glycosides from starfish, and two others concern triterpene glycosides from sea cucumbers. One article describes the effect of a glycosaminoglycan from the sea cucumber Apostichopus japonicus on hyperglycemia in the liver of insulin-resistant mice. One article concerns the isolation of 10 new triterpene glycosides from a fungus associated with a sea cucumber. The article by Dworaczek et al. characterizes the O-specific polysaccharide (O-antigen) of a bacterial pathogen of common carp by chemical and immunochemical methods. In total, the Special Issue comprises14 articles, including the editorial and two reviews.
Selected as a Children's Poet Laureate Monthly Book Pick, Sea Star Wishes captures the varied and colorful world of our beautiful coastal shores. Discover the wonders of the sea and enjoy a day at the beach in playful and imaginative poetry and illustrations. In these coastal poems for kids, children meet sea lions, starfish, jellyfish, and other animals in the ocean, and dream about sandcastles and other beach activities. This fun, lyrical children's poetry collection by award-winning children's singer and songwriter Eric Ode features lively illustrations by Washington State Book Award recipient Erik Brooks. Sea Star Wishes Do sea stars make wishes on stars of the night and dream that they might be as shiny and bright? And if they make wishes perhaps it could be that fishes make wishes on stars of the sea.
This book is a printed edition of the Special Issue "Biology, Ecology and Management of Crown-of-Thorns Starfish" that was published in Diversity
A multitude of direct and indirect human influences have significantly altered the environmental conditions, composition, and diversity of marine communities. However, understanding and predicting the combined impacts of single and multiple stressors is particularly challenging because observed ecological feedbacks are underpinned by a number of physiological and behavioural responses that reflect stressor type, severity, and timing. Furthermore, integration between the traditional domains of physiology and ecology tends to be fragmented and focused towards the effects of a specific stressor or set of circumstances. This novel volume summarises the latest research in the physiological and ecological responses of marine species to a comprehensive range of marine stressors, including chemical and noise pollution, ocean acidification, hypoxia, UV radiation, thermal and salinity stress before providing a perspective on future outcomes for some of the most pressing environmental issues facing society today. Stressors in the Marine Environment synthesises the combined expertise of a range of international researchers, providing a truly interdisciplinary and accessible summary of the field. It is essential reading for graduate students as well as professional researchers in environmental physiology, ecology, marine biology, conservation biology, and marine resource management. It will also be of particular relevance and use to the regulatory agencies and authorities tasked with managing the marine environment, including social scientists and environmental economists.
National Park Service

If you’ve ever had a medical check-up, did you wonder why they put a cuff around your forearm, gave it a squeeze, and made you sit still and quiet? Or why they asked you to open your mouth so they could stick a thermometer under your tongue? Or put that cold stethoscope against your chest while you took deep breaths followed by sticking a clothespin thingamabob on your finger? What’s up with all the gizmos and gadgets and why all the bother?

What’s up is that all of these instruments measure the conditions of some of the most important, life-supporting functions, or vital signs, which keep your carcass from becoming, well, a carcass. The squeezy cuff is reading your blood pressure, which indicates how strongly your blood is pumping through your pipes. The thermometer measures your core body temperature, which affects many chemical reactions in your body that supply energy for your cells. With a stethoscope, the swooshing sound of air moving in and out of your lungs can be listened to. And the clothespin doohickey tracks the amount of oxygen being carried by your blood. Vital signs are critical indicators of your body’s overall health. By tracking them as you grow and mature, these measurements can be used as a guide or reference point for when your body isn’t feeling all that great.

Now what does your blood pressure have to do with US National Parks? While human vital signs are important in evaluating your body’s health, ecological vital signs are indicators for measuring ecosystem health. An ecosystem is a community of living organisms like frogs, trees, or bacteria, and nonliving materials such as water, dirt, and rocks that are located together and interact on some level. In a healthy ecosystem, all of the living and nonliving members exist in a state of natural balance in harmony with their environment. When something new enters the community, say a strange weed or insect, or something in the environment shifts, such as the air temperature becoming warmer, the health of the ecosystem can be threatened. Monitoring ecological vital signs gives scientists a reference point or baseline of the natural condition and alerts them when there is a change. While a healthy ecosystem can continue to support all its members and adapt to change, sometimes changes are too great and members of the ecosystem become stressed and have a hard time keeping up.

Although US National Parks are some of the most protected areas on the planet, the ecological health of many of these carefully safeguarded lands is increasingly uncertain due to our rapidly changing global environment. Here we present a collection of articles about how we study and understand the health of park ecosystems by measuring and tracking the condition of ecological vital signs. This scientific data helps park managers protect the valued resources of our parks and lessen harmful impacts when change is inevitable.
