The ecology of sandy shores
The Ecology of Sandy Shores provides the students and researchers with a one-volume resource for understanding the conservation and management of the sandy shore ecosystem. Covering all beach types, and addressing issues from the behavioral and physiological adaptations of the biota to exploring the effects of pollution and the impact of man's activities, this book should become the standard reference for those interested in Sandy Shore study, management and preservation. * More than 25% expanded from the previous edition* Three entirely new chapters: Energetics and Nutrient Cycling, Turtles and Terrestrial Vertebrates, and Benthic Macrofauna Populations * New sections on the interstitial environment, seagrasses, human impacts and coastal zone management* Examples drawn from virtually all parts of the world, considering all beach types from the most exposed to the most sheltered

A student's guide to the seashore
\"This unique, concise and beautifully-illustrated guide allows students to identify over 650 of the common, widespread animals and seaweeds of the shore. User-friendly dichotomous keys are supported by details of diagnostic features and biology of each species. Now enhanced with 32 pages of colour, this much acclaimed guide is invaluable to students of marine biology at any level. Questions such as how does the species reproduce? What is its life-cycle? How does it feed? are answered in the notes accompanying each species to give a fascinating insight into the diversity and complexity of life on the shore. The text is supported by an extensive glossary of scientific terms and a comprehensive bibliography is included to aid further study. The third edition builds on the excellent reviews of earlier editions and will continue to appeal to a wide readership, including students, teachers and naturalists\"-- Provided by publisher.

The 2021 report of the Lancet Countdown on health and climate change: code red for a healthy future
The 2021 report coincides with the UN Framework Convention on Climate Change 26th Conference of the Parties (COP26), at which countries are facing pressure to realise the ambition of the Paris Agreement to keep the global average temperature rise to 1·5°C and to mobilise the financial resources required for all countries to have an effective climate response. To meet the Paris Agreement goals and prevent catastrophic levels of global warming, global greenhouse gas emissions must reduce by half within a decade. [...]at the current pace of reduction, it would take more than 150 years for the energy system to fully decarbonise (indicator 3.1), and the unequal response between countries is resulting in an uneven realisation of the health benefits of a low-carbon transition. With a slower pace of decarbonisation and poorer air quality regulations than countries in the very high HDI group, the medium and high HDI country groups produce the most fine particle matter (PM2·5) emissions and have the highest rates of air pollution-related deaths, which are about 50% higher than the total deaths in the very high HDI group (indicator 3.3).

The Sea
Sailing across time and geography, the imaginary and the real, The Sea chronicles the many physical and cultural meanings of the watery abyss. This book explores the sea and its meanings from ancient myths to contemporary geopolitics, from Atlantis to the Mediterranean migrant crisis. Richard Hamblyn traces a cultural and geographical journey from estuary to abyss, beginning with the topographies of the shoreline and ending with the likely futures of our maritime environments. Along the way he considers the sea as a site of work and endurance; of story and song; of language, leisure, and longing. By meditating on the sea as both a physical and a cultural presence, the book shines new light on the sea and its indelible place in the human imagination.

Genome-Wide Identification and Transcriptomic Analysis of MYB Transcription Factors in Seashore Paspalum Under Salt Stress
The MYB transcription factor family plays crucial roles in plant growth, development, and responses to biotic and abiotic stresses. Seashore paspalum (Paspalum vaginatum) is a halophytic grass species with remarkable salt tolerance, yet its MYB gene family has not been systematically characterized. In this study, we conducted a genome-wide identification of MYB genes in seashore paspalum using a Hidden Markov Model (HMM)-based approach, resulting in the identification of 157 PvMYB genes. Phylogenetic and conserved motif analyses revealed distinct subfamily groupings and evolutionary relationships within the PvMYB family. Promoter analysis indicated that PvMYB genes contain multiple cis-acting elements responsive to light, hormones, and abiotic stresses, suggesting their potential regulatory roles under salt stress. Collinearity and duplication analyses demonstrated that gene duplication events contributed to the expansion of the PvMYB family. Moreover, protein interaction network prediction suggested that PvMYB73 may interact with key regulatory proteins such as BZIP8 and DREB1F involved in salt stress signaling. Transcriptome and reverse transcription quantitative PCR (RT-qPCR) analyses showed that PvMYB90, PvMYB123, and PvMYB150 were upregulated in leaves and roots under salinity stress, while PvMYB85 and PvMYB90 were experimentally validated to localize in the nucleus and function in salt tolerance regulation. Collectively, this study provides the first comprehensive characterization of the MYB gene family in seashore paspalum and offers valuable insights into the molecular mechanisms underlying salt tolerance in halophytic grasses.

Bloodworms and other wriggly beach dwellers
Hidden from view under the sand, a hunter is searching for a meal. It's a hungry bloodworm and it has spotted a tiny crab. Suddenly, an alien-like proboscis shoots from its head revealing four sharp fangs. The worm injects venom into its prey, paralyzing and killing the little crab. Then the bloodworm slurps up the crab's soft insides!

Global Human Footprint on the Linkage between Biodiversity and Ecosystem Functioning in Reef Fishes
Difficulties in scaling up theoretical and experimental results have raised controversy over the consequences of biodiversity loss for the functioning of natural ecosystems. Using a global survey of reef fish assemblages, we show that in contrast to previous theoretical and experimental studies, ecosystem functioning (as measured by standing biomass) scales in a non-saturating manner with biodiversity (as measured by species and functional richness) in this ecosystem. Our field study also shows a significant and negative interaction between human population density and biodiversity on ecosystem functioning (i.e., for the same human density there were larger reductions in standing biomass at more diverse reefs). Human effects were found to be related to fishing, coastal development, and land use stressors, and currently affect over 75% of the world's coral reefs. Our results indicate that the consequences of biodiversity loss in coral reefs have been considerably underestimated based on existing knowledge and that reef fish assemblages, particularly the most diverse, are greatly vulnerable to the expansion and intensity of anthropogenic stressors in coastal areas.
