The quantification of the total number of cetaceans or pinnipeds within a certain population or geographic area. Repeating abundance estimate surveys over time in a specific area is an important tool to understand if the number of animals is growing or declining over time. This allows scientists and policymakers to make informed decisions about conservation strategies and management practices.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t

\u201c<\/strong>The natural process by which a living species becomes the best fitted for its environment. Adaptations are a result of natural selection\u2019s acting upon heritable\u00a0variation\u00a0over several generations\u201d (Gittleman, 2022). Organisms adapt in many different ways, their body structure, their physiology, the way they move through their environment, and even on a genetic and molecular level. For instance, the blowhole at the top of a dolphin\u2019s head is an adaptation that allows it to keep swimming without slowing down to breathe by sticking its entire face out of the water.<\/p>\n\t\t<\/div>\n\t\t\t\t<\/article>\n\t\t\t\t

Adaptive management is a structured, step-by-step approach to improving resource management by learning from the outcomes of past decisions. It involves making decisions in the face of uncertainty, closely monitoring the results, and adjusting strategies over time. The goal is to reduce uncertainty and improve decision-making by continuously refining practices based on what is learned. It emphasises accountability and clarity in each decision-making step, allowing for flexibility and better long-term management of resources. <\/p>\n\n

Quick growth in the population of algae in freshwater or marine ecosystems, as a result of excessive nutrients in the environment. \u00a0It is usually characterised by changes in the colouration of the sea depending on which species of algae have caused the bloom (red, brown or green). These blooms have a harmful effect on the environment and other species that live in the area: the limit the amount of light that penetrates the water surface, use up all the oxygen in the water and suffocate other organisms, and even produce toxins as a by-product of their metabolism.<\/p>\n\n\n\n

Also known as grey amber. Solid, waxy substance produced in the sperm whale intestines. Fresh ambergris is black, soft, and has unpleasant smell, while exposing to sun causes it to harden, become light grey or yellow, and get pleasant smell it is recognised for. In sperm whales, it is assumed to protect intestines from irritation caused by undigestible objects like squid beak or cuttlebone. In Eastern cultures it is used in medicine, potions, and as a spice, while in the Western cultures it has use as a perfume stabiliser (Encyclop\u00e6dia Britannica<\/em>). <\/p>\n\n

A learned, cooperative feeding strategy that involves a group of whales. Humpback whales and Bryde\u2019s whales use this strategy. A whales circle a school of small fish or swarms of krill they are hunting and start blowing bubbles. The fish are unable to escape this \u201cnet\u201d of bubbles and stay trapped. Then whales swim with their mouths open through the trapped fish, and effectively feed themselves. <\/p>\n\n

A marine protected area (MPA) is a clearly defined region established to conserve marine biodiversity, ecosystem health, and cultural heritage. As part of a globally connected network, MPAs help safeguard marine resources while ensuring the continued supply of essential ecosystem services. Effects of MPAs can be seen not just in the areas themselves, but also surrounding areas, as marine life \u201cspills\u201d over the boarders of the MPA increasing biodiversity and biomass in the areas around it. Not all MPAs have the same level of protection: while some are fully protected and nothing can be taken from there, others allow for some level of resource extraction.<\/p>\n\n\n\n

A powerful burst of air, expelled from a whales blowhole, which creates a spray-like blow around the whale\u2019s head. A whale\u2019s spout can be used to recognise a whale species from afar. This is because each species, with their characteristic size and blowhole type, will have a different spout. <\/p>\n\n
