Temporal and Spatial Variations in the Species Composition, Distribution, and Abundance of Copepods in Kaohsiung Harbor, Taiwan

並列摘要


The composition, distribution, and abundance of copepods collected from surface waters of Kaohsiung Harbor were examined. Copepods were collected quarterly at 7 designated stations from Jan. 1999 to Oct. 2001. In the inner harbor, 58 species in 28 families of copepods were recorded; the average abundance was 1.45 x 105 individuals/1000 m3. The 7 dominant species, which made up 66.6% of the overall collection, were Temora turbinata (18.5%), Acartia erythraea (16.4%), Paracalanus parvus (16.2%), P. aculeatus (6.4%), Pseudodiaptomus marinus (4.3%), A. negligens (2.7%), and A. spinicauda (2.1%). While A. erythraea and P. parvus were abundant at the inner harbor stations, T. turbinata was found mostly at one of the 2 outer harbor stations. Two-way ANOVA analysis of total abundance showed a significant seasonal effect (F = 6.83, p < 0.01), but not between stations (F = 0.24, p > 0.05). Multidimensional scaling (MDS) analysis of each cruise revealed an abundance difference with a low in July and a high in Apr. It also distinguished 1999 as a low abundance year. The range of the species diversity index (H , ) for each cruise was 1.21 to 3.79, with an average of 2.78 ± 0.59. The species diversity index was generally similar between stations, but was lower in Jan. and higher in Oct..
