The open-ocean midwater is the largest habitat for animal life on Earth, and one of the most homogeneous environments in space and time. However, these waters harbor complex food webs involving predatory animals from manifold phyla, presenting unique adaptations to capturing the…

Procurou-se com este ensaio entender de que modo o mar pode ser um espaço adverso ao fotógrafo no contexto da pesca e entender como este ultrapassa essas dificuldades, inerentes ao meio, ao habitar esse espaço com a sua máquina fotográfica e experienciar o mar não apenas como um…
The effect of changing anthropogenic mercury emissions on marine wildlife is of broad interest. Methylmercury can cause reproductive and neurological damage and biomagnifies in food webs. Mercury availability in the Pacific Ocean has been increasing and therefore could be expect…
The US Northeast Shelf (USNES) provides habitat for many economically and ecologically important fish species and is one of the most rapidly warming regions in the world. A common response from several fishes to warming has been poleward distribution shifts, potentially includin…
Novel molecular isotope proxies measured in bivalve tissues represent a wide range of approaches for tracing ecological and climatological change through time and space. In comparison to other oceanographic data used to reconstruct modern and past biogeochemical cycles (e.g., ma…
Connectivity refers to the amount of gene flow present between populations of the same species. The transfer of genetic material between populations allows species to increase their genetic diversity, thus allowing advantageous mutations to spread. When gene flow between populat…
Oxygen minimum zones (OMZs) are areas in which midwater oxygen concentration can be significantly lower than in non OMZ areas at comparable depths. OMZs are of great interest because of the limits oxygen availability places on life. The potential for OMZ expansion with warming o…
Increases in near-surface algal concentrations in the northern Arabian Sea from 1997 to 2004 have been linked to the appearance of the mixotrophic dinoflagellate Noctiluca miliaris (also known as Noctiluca sscintillans ). This emerging presence of N. miliaris is ultimately expec…
Coral reefs, one of the most productive and diverse ecosystems on earth, not only protect adjacent costal areas from erosion, but also serve as an economical assess for human populations, providing as well a major source of protein to hundreds of million of people. Anthropogenic…
Understanding the spatial scales over which populations of coral reef fishes are connected is important for elucidating the evolutionary mechanisms generating biodiversity. Describing connectivity also is vital for setting conservation priorities to protect that biodiversity. Di…
En milieu marin, l'appréhension et la maîtrise des échelles de variation spatiale et temporelle représentent une condition indispensable à la compréhension de la dynamique et de la structure des populations. Dans les systèmes d'archipels, ces processus sont influencés par des in…
Larval dispersal in marine species allows gene flow across broad expanses of pelagic ocean, and can potentially provide genetic cohesion within widespread species. However, genetic connectivity across discontinuous ranges spanning thousands of kilometers must also rely on the av…
The subfamily Epinephelinae (Groupers) is a major group of commercially important fishes of the world with 19 species reported from Puerto Rico. The goal of the present study was characterize the diversity of parasites that affect groupers in Puerto Rico. A total of 54 species o…
The freshwater ecosystems of Southeast Asia are some of the most highly threatened in the world, due to anthropogenic impact from climate change, deforestation, the creation of hydropower dams and over-harvesting. Rapid, cost-effective and reliable monitoring of biodiversity is …
To evaluate the clam Amiantis umbonella as a bio-indicator of metal contamination, the concentrations of a number of metals (Hg, Cd, Pb, Cu, Ni, Mn, Cr, V, Zn, and Fe) were determined in clam's soft tissues, in different organs, water, and sediment in Kuwait Bay of the Arabian G…
The State of Kuwait is situated at the northwestern end of the Persian Gulf and has a population of 2.5 million people, the vast majority of whom live along the southeastern stretch of its 500 km coastline. Kuwait Bay, a shallow natural harbor situated at the eastern "mouth" of …
