Spatial and Seasonal Variation in the Taxonomic Diversity of Soft-Bottom Fish Communities in San Ignacio Lagoon, Baja Caifornia Sur, Mesxico | Chapter 7 | Current Research on Geography, Earth Science and Environment Vol. 4

 

San Ignacio Lagoon, located in northwestern Baja California Sur, is an important site for commercial fisheries; however, studies specifically addressing the taxonomic diversity of its fish communities remain scarce. To fill this gap, we assessed the diversity of fish associated with soft-bottom habitats across 11 sites from spring 1998 to winter 1999, using alpha, beta, gamma, and taxonomic distinctness indices (Δ* and Δ+). A total of 1,361 specimens representing 44 species and 35 genera were recorded. Seasonal analysis revealed the highest alpha diversity in summer, while beta diversity peaked in spring. Gamma diversity was greatest in spring and summer, with 27 species each. Spatial analysis showed significant differences in Δ+, whereas temporal variation was not significant. These findings highlight the ecological importance of San Ignacio Lagoon and provide baseline data for future monitoring and conservation.

Analysis of the Variation in the Taxonomic Distinction of Soft-bottom Fishes in a Lagoon on the West Coast of the Gulf of California, Mexico | Chapter 3 | Newest Updates in Agriculture and Veterinary Science Vol. 4

 Mexico is a country accompanying high biodiversity. The marshy lagoon of La Paz is in contact the west coast of the Gulf of California, south of La Paz Bay, in united states of america of Baja California Sur, Mexico, and is known by residents as Ensenada de La Paz. The goal concerning this study was to decide the taxonomic distinctness concerning this lagoon's comfortable-bottom fish society. From August 2016 to June 2017, bi-monthly example were conducted in seven various locations, flexible a total of 42 replicates. An experimental fish net was used to catch the fish, and a 22 extremities boat accompanying a 75 HP was used as a angler. Ecological indices to a degree Fisher’s alpha variety (α-Fisher), taxonomic distinctness (TD Δ*) and average taxonomic discreteness (AvTD Δ+), were used to describe the current state concerning this coastal pond. A total of 2,763 organisms from 73 class, 50 genera, 29 offspring, nine orders, and two classes were collected. The plurality of the species were top-secret into five families. Despite the fact that this bayou has been assign anthropogenic impact through the discharge of wastewater from the city of La Paz, our findings (relating to space and temporal α-Fisher, Δ TD * and AvTD Δ+) display that it is in good condition.
