Up, Down, and All Around: Courtship Behavior Deviants and Genetic Divergence in the Reef-Dwelling Bioluminescent Ostracod, <i>Photeros annecohenae</i> (Myodocopida: Cypridinidae). [PDF]

Ecol Evol
Species that have complex courtship behaviors are some of the most evolutionarily diverse lineages observed in nature. Here, we quantify differences in the courtship behavior, morphology, and genetics of a group of bioluminescent marine ostracod residents of the Mesoamerican barrier reef of Belize.

Short-term impacts of salinity pulses on ionic ratios of the seagrasses Thalassia testudinum and Halodule wrightii [PDF]

, 2015
We examined the effects of short-term salinity pulses on ion accumulation in the seagrasses Thalassia testudinum and Halodule wrightii. Plant fragments were exposed for approximately 1 week to 10, 23 (ambient salinity), 30, 40, 50 and 70 psu.

Composición química de la seiba (Thalassia testudinum K.D. Koenig, 1805)

Revista de Investigaciones Marinas, 2022
La perspectiva de usar las hojas de seiba como suplemento alimentario para el ganado o como abono agrícola requirió determinar la composición química de sus hojas con los siguientes resultados: peso seco 17-34%; cenizas 21-52%; carbono 23-50%; proteínas 8-12%; azúcares reductores 2-13%; fibras 29-40% y grasas 0,5-0,7% con variaciones entre hojas sin ...

Experimental evidence of pollination in marine flowers by invertebrate fauna

Nature Communications, 2016
Marine plants reproduce by hydrophilly, that is, the movement of pollen by water. Here, the authors show that invertebrates can also carry pollen from male to female Thalassia testudinum plants.

Sea grasses, a new unreported habitat for the heterobranch mollusk Umbraculum umbraculum in the Caribbean region

Marine and Fishery Sciences, 2020
Herein, a new habitat for the heterobranch mollusk Umbraculum is described. One specimen was found on a Thalassia testudinum bed at Taganga Bay at 3 m depth, a buffer area of the Tayrona National Park, Colombian Caribbean.

Nitrogen uptake and internal recycling in Zostera marina exposed to oyster farming: eelgrass potential as a natural biofilter [PDF]

, 2016
Oyster farming in estuaries and coastal lagoons frequently overlaps with the distribution of seagrass meadows, yet there are few studies on how this aquaculture practice affects seagrass physiology.

Stable isotopes reveal complex changes in trophic relationships following nutrient addition in a coastal marine ecosystem [PDF]

, 2009
Complex links between the top-down and bottomup forces that structure communities can be disrupted by anthropogenic alterations of natural habitats.We used relative abundance and stable isotopes to examine changes in epifaunal food webs in seagrass ...

Effects of community structure on the seagrass Thalassia testudinum [PDF]

Marine Ecology Progress Series, 1999
The influence of community structure on the seagrass Thalassia testudinum was studied in 3 distinct communities low and high density monocultures, and patches intermixed with Halodule wrightii, in Cockroach Bay, Tampa, Florida. T. testudinum shoot-specific leaf mass and growth were significantly higher in low density monocultures, and both variables ...

Spatial and seasonal variability in elemental content, δ13C, and δ15N ofThalassia testudinum from South Florida and its implications for ecosystem studies [PDF]

, 2005
Elemental and isotopic composition of leaves of the seagrassThalassia testudinum was highly variable across the 10,000 km2 and 8 years of this study. The data reported herein expand the reported range in carbon:nitrogen (C:N) and carbon:phosphorus (C:P ...

CO2 and nutrient-driven changes across multiple levels of organization in zostera noltii ecosystems [PDF]

, 2014
Increasing evidence emphasizes that the effects of human impacts on ecosystems must be investigated using designs that incorporate the responses across levels of biological organization as well as the effects of multiple stressors.
