The Dynamic Duo: Application of Complementary BRUVs and eDNA to Marine Fish Assemblages
Innovations in waterproofing cameras and DNA analysis have led marine scientists to apply these methods in unique ways in recent decades. Through the use of BRUVs and eDNA this article looks at fish assemblages in Jurien Bay Marine Park in Western Australia to compare these methods individually and combined. When BRUVs and eDNA were both […]
Far-Flung Relatives: A seabird’s story of population fragmentation
The Peruvian diving petrel was once abundant along the Pacific coast of South America. These days, though, only seven breeding colonies dot the coastline, separated by dozens of miles. Conservation efforts were initially aimed at the species as a whole, but a recent study has uncovered evidence that calls into question how effective those efforts […]
The Gulf of Mexico Triangle: Assessing Movements of Large Pelagic Fish Across Multiple National Boundaries
Pelagic predators or difficult to manage due to their vast migrations through through multiple countries jurisdictions and international waters. In order to effectively manage these species multinational agreeements are required. However, collecting movement data for species that travel long distances is difficult to collect. Here, researchers look at the movements between countries of 8 species […]
Citizen Science, Oh My!
To understand ecosystem level changes, it is important to monitor an ecosystem over a long period of time. However, long-term funding can be limited, especially during times of economic hardships. How do researchers carry out long-term ecological studies in place where sustained funding is unavailable? Read this article to get a glimpse into citizen science, […]
If the benthos could talk: the value of long-term biodiversity monitoring
The tiny critters that burrow, swim, and graze in the benthic (bottom) habitats of marine ecosystems are often monitored over long time periods so that researchers can measure changes in biodiversity over time. Read on to find out how researchers used long-term benthic data from Narragansett Bay to link human activities with changes in biodiversity. […]
Linking marine and human health in Hispaniola
Biodiversity is often associated with higher standards of human livelihood, but researchers have yet to draw a direct line between healthy marine ecosystems and humans. Read on to learn how national infrastructure can complicate the relationship between biodiversity and human health. Katherine BarrettKate is a 3rd year PhD candidate in the Biological Sciences Department at […]
Benthic biology on a thermally boring deep-sea ridge
The deep ocean is vast and full of neat ocean dwellers, many of which scientists know little about. One way to investigate them is from images and videos captured during deep-sea exploration efforts using submersibles. A group of scientists did just that to quantify the benthic assemblages at different depths and a variety of substate […]
Marine Protected Areas need more than just a name
It is no secret that the Earth’s oceans are in trouble. Every day there is a new article on rising temperatures, ocean acidification, coral bleaching, and species extinction, to name just a few. Luckily, governments are taking notice and policies are being enacted to curb the loss of this delicate, and essential ecosystem. However, deciding […]
Protecting Our Fish and Birds by Protecting Their Wetland Homes
Wetlands are the link between land and water, and are some of the most productive ecosystems on Earth. They need our protection, for the commercial fisheries we depend upon, for the recreational opportunities they provide us, and for the benefit of the species that use them. Zoe GentesZoe has an M.S. in Oceanography and a […]
‘The conservationist is ready to see you’: triaging marine ecosystems in times of climate change
Climate change affects ecosystems worldwide, but how do conservationists decide which of planet earth’s ecosystems are most in need? Abrahim El GamalAbrahim is a PhD student at Scripps Institution of Oceanography in San Diego where he studies marine chemical biology.
