Ecology Of Seagrass Fishes And Macroinvertebrates On Guatemala's Atlantic Coast., Alejandro Arrivillaga Jan 2000

Ecology Of Seagrass Fishes And Macroinvertebrates On Guatemala's Atlantic Coast., Alejandro Arrivillaga

LSU Historical Dissertations and Theses

The ecology of fishes and macroinvertebrates inhabiting shallow seagrass beds was studied at Bahia La Graciosa, located in Amatique Bay in the Caribbean coast of Guatemala. The study area included extensive turtle grass, Thalassia testudinum, meadows over muddy substrate, whereas a more exposed shoreline also supported turtle grass meadows over sandy substrates outside the bay. A total of 166 samples were collected across two seasons and habitat types in three sampling trips to the area with a cylindrical drop sampler. Diversity and abundance of fishes and macroinvertebrates inhabiting seagrass and adjacent bare-sand sites were described to assess the relative importance …

Molecular Systematics Of The Green Algal Order Trentepohliales (Chlorophyta)., Juan Manuel Lopez-Bautista Jan 2000

Molecular Systematics Of The Green Algal Order Trentepohliales (Chlorophyta)., Juan Manuel Lopez-Bautista

LSU Historical Dissertations and Theses

Molecular, karyological, and nuclear genome quantification data from representatives of the order Trentepohliales (Chlorophyta) were used to infer evolutionary relationships with other green algal classes and orders. Phylogenetic analyses of the nuclear-encoded small subunit ribosomal DNA (18S rDNA) sequences from taxa representing all of the major lineages of green algae consistently indicated that the subaerial Trentepohliales are closely related to Ulvophycean marine green algae, particularly to the siphonous and hemisiphonous orders. The phylogenetic distribution of continuous and discontinuous types of mitochondrial large subunit ribosomal RNAs (mtLSU rRNA) in green algae has been shown to be consistent with phylogenetic relationships previously …
