“…Water temperature and dissolved oxygen are variables inversely related (Lewis 1987; Khani and Rajaee 2017; Koralay et al 2018); nevertheless, in this study, a direct relationship was observed, these variations might be explained more by biological effects (photosynthesis-respiration) than by physical aspects (Cervantes-Martínez and Gutiérrez-Aguirre 2015). pH values were closer to the neutrality, probably due to the limestone buffer, according to Razo et al (2004) and Grochowska (2020).…”

This work reports the freshwater copepod Paracyclops novenarius, in a water body with high arsenic concentrations. Morphologic analysis, abundances, body size of the copepod and physical and chemical variables of the water (including arsenic concentrations) were evaluated in two different climatic seasons (rainy and dry). Morphological analysis showed that the high arsenic concentrations do not affect the morphology of P. novenarius, including all its development and adult instars. The highest abundances of this species were found in the dry season for all development stages, with values of 1.51 and 1.50, 4.46, 0.21 ind/L-1, for nauplii, copepodites, females, and males, respectively. However, these values are lower than other aquatic systems of the region and the world, without polluting agents. The highest arsenic concentration was found in the dry season (58 mg/L-1) and the lowest during the rainy (54.5 mg/L-1). The body size of the analyzed organisms was larger in rainy compared to dry, with an average of 637.2 ± 42 µm for females and 650 ± 37 µm for males. A Mann-Whitney U test showed significant differences in lengths by season and by arsenic concentration (U = 1284.5, U = 1284.5; p < 0.05). The results of this study could provide information for environmental impact assessments on aquatic systems.

“…It was recorded between 5.70 and 6.70 mg.L -1 . This factor has strong negative association with temperature (Koralay et al 2018), whereas the decrease of DO will result in obstruction of algae diversity and biomass (Haas et al 2014). However, this study suggested positive correlation from both factors instead.…”

Abstract. Mahmudi M, Lusiana ED, Herawati EY, Serihollo LG. 2020. Environmental factors and seasonal effects on the potential harmful algae presence at Ambon Bay, Indonesia. Biodiversitas 21: 3101-3107. Marine and coastal areas are susceptive to harmful algae presence which can lead to Harmful Algae Blooms (HABs). Major drivers for this event are climate change, domestic and industrial activities. These alter the environmental condition in marine ecosystems which caused the shift of phytoplankton community. This study aims to analyze the environmental factors affecting the harmful algae occurrence in Ambon Bay as well as the seasonal change during west monsoon and first transition in regards to this issue. There were six environmental variables accounted in this research which measured in situ and ex-situ. The results showed that there were three algae divisions that formed the phytoplankton structure in Ambon Bay, namely Bacillariophyceae, Dinophyceae, and Cyanophyceae. These divisions have been reported as the cause of previous HABs in the area. Furthermore, algae density during first transition season was higher than during west monsoon season, but the composition of phytoplankton community was stable in which dominated by harmful algae such as Chaetoceros, Skeletonema, Nitzschia, Ceratium, Pyrodinium, Dinophysis, Alexandrium, and Trichodesmium. Meanwhile, based on Canonical Correspondence Analysis (CCA), temperature and nutrients were the main factors that highly associated with the presence and abundance of harmful.

This study aims to describe Limboto Lake's condition based on the spatial-temporal abundance of phytoplankton and the presence of harmful algae species. Sampling was conducted in February, March, and April 2018 at six stations. The phytoplankton found in Limboto Lake consisted of 7 divisions from 80 species, namely Chlorophyta (35 species), Euglenophyta (17 species), Bacillarophyta (13 species), Cyanophyta (7 species), Cryptophyta (4 species), Dinophyta (3 species) and Chyrosphyta (1 species). The results of the phytoplankton distribution analysis in Limboto Lake varied on average among stations as well as observation times. The results show that the average of phytoplankton abundance at stations 1, stations 2, stations 3, and stations 4 categorized as medium polluted waters with 4,903 ind/L, 5,000 ind/ L, 9,418 ind/L, and 10,049 ind/L, respectively. The abundance at station five is included in the lightly polluted category with an average phytoplankton abundance of 1,541 ind/L, while station 6 is in the heavily polluted category with the average value of 20,894 ind/L. Species that can be used as indicator species for pollution are those with the highest abundance value, namely Microcystis sp., which indicates that Limboto Lake contains high nitrate and phosphate.
