For approximately 3,000 years, generations of green sea turtles have returned to the same seagrass meadows to eat. The fact that this stretches over many generations highlights the importance of protecting seagrass meadows along the coasts of North Africa.

In a new study, researchers have found that the restoration efforts of the critically endangered species elkhorn coral depend largely on the animal's location, microbiome, and the right conditions to provide an abundance of food.

Oceanic islands provide useful models for ecology, biogeography and evolutionary research. Many ground-breaking findings -- including Darwin's theory of evolution -- have emerged from the study of species on islands and their interplay with their living and non-living environment. Now, an international research team has investigated the flora of the Canary Island of Tenerife. The results were surprising: the island's plant-life exhibits a remarkable diversity of forms. But the plants differ little from mainland plants in functional terms. However, unlike the flora of the mainland, the flora of Tenerife is dominated by slow-growing, woody shrubs with a 'low-risk' life strategy.

Plant diversity in nature is generally highest in tropical regions around the equator, with decreasing diversity closer to the poles. Researchers now show that the plant specimens housed in herbaria in Europe and North America are more comprehensive and diverse than the collections housed in the countries with more natural plant diversity.

Many landscapes in the tropics consist of a mosaic of different types of land use. How people make use of these different ecosystems, with their particular plant communities, was unclear until now. Researchers, many of them from Madagascar, have now investigated this. When considering biodiversity, forests often get the most attention. But this research shows that rural households use a wide range of plant species and services provided by many nearby ecosystem types.

Algorithms can predict what movies or songs you might like, but they can also predict which species a predator would most likely eat. Researchers have been using machine learning to identify species interactions, and can predict which species are most likely to go extinct, so that intervention can be planned before this happens.

A team has identified a protein that modifies the cellular machinery responsible for producing cellulose, which could inform the design of more stable, cellulose-enriched materials for biofuels and other functions.

Research shows global cooling of the climate 10 million years ago led to an explosion of diversity in terrestrial orchids.

Scientists have unveiled a new mechanism that plants use to sense temperature. This finding could lead to solutions to counteract some of the deleterious changes in plant growth, flowering and seed production due to climate change.

Financial payments made by land developers to offset their impacts on threatened species may fall short, according to new research.

Plant roots have their own thermometer to measure the temperature of the soil around them and they adjust their growth accordingly. Through extensive experiments, a team was able to demonstrate that roots have their own temperature sensing and response system. In a new study, the scientists also provide a new explanation for how roots themselves detect and react to higher temperatures. The results could help develop new approaches for plant breeding.

Indonesia, home to the largest tropical rainforest in Southeast Asia and over 17,500 islands, is a country packed with biodiversity and endangered species. However, scientists studying the region's species and ecosystems are getting banned from Indonesia, and conservation plans are being blocked. A team of conservation researchers with long-term experience in Indonesia discuss scientific suppression and other research challenges they have witnessed while working in the region. They offer suggestions for how to promote nature conservation, protect data transparency, and share research with the public in this and other regions of the world.

Extinct dwarf hippos that once roamed Madagascar lived in forests rather than open grasslands preferred by common hippos on mainland Africa. The findings suggest grasslands that now cover much of the enormous island off the eastern coast of southern Africa were a relatively recent change facilitated by people rather than a natural habitat sustained in part by these famously large vegetarians.

Research has revealed that Queensland native forestry, including timber harvesting, could actually help conserve biodiversity and mitigate climate risks.

Researchers are using a new model to clarify why millions of years ago more animal species from Asia made the leap to the Australian continent than vice versa. The climate in which the species evolved played an important role.

Analysis of global tracking data for 77 species of petrel has revealed that a quarter of all plastics potentially encountered in their search for food are in remote international waters -- requiring international collaboration to address.

Amazon river dolphins are under threat from fishing and proposed new dams and dredging, research shows.

Increasing opportunities for up-close encounters with sharks and other animals are making wildlife tourism one of the fastest growing tourism sectors -- leading ecology experts to venture to one of the world's main sites to investigate the effects of tourism on endangered whale sharks. At Oslob in the Philippines, Flinders University's Southern Shark Ecology Group and Global Ecology Lab joined local Filipino researchers to measure how the daily feeding regimes for resident whale shark population might have affected their behaviour and physiology by assessing their activity and metabolic requirements.

Researchers have closely examined the brain activity and skin patterning in octopuses (Octopus laqueus) during active sleep and discovered that it closely resembles neural activity and skin patterning behavior seen when awake.
