“…The record of this genus in Thailand is unexpected since members of this genus inhabit water bodies across Eurasia, North Africa, and North Asia, including China [38]. In Southeast Asia, only Arctodiaptomus dorsalis (Marsh, 1907) has been recorded in more than 20 lakes in the Philippines [39]. This Neotropical species was originally described from the United States and has been found across Central Amer-ica to northern South America [40].…”

The diversity, distribution, and checklist of diaptomid copepods from various freshwater ecosystems throughout Thailand are presented, based on data from our biodiversity projects during 1993–2019 and literature reviews. Thailand has one of the most diversified diaptomid fauna in the world, with 42 species identified from 2150 localities (4962 samples). Mongolodiaptomus has the highest species richness with ten species, followed by Tropodiaptomus with seven species. Among these, eight taxa (Arctodiaptomus sp., Mongolodiaptomus pectinidactylus, Neodiaptomus meggitti, Tropodiaptomus hebereri, T. lanaonus, T. oryzanus, T. ruttneri, and Paradiaptomus greeni) are new to the fauna of Thailand. The rare P. greeni, which predominantly occurs in Africa, is also a new record for Southeast Asia. The most frequently encountered species were Mongolodiaptomus botulifer, Phyllodiaptomus praedictus, M. calcarus, M. dumonti, M. malaindosinensis, Vietodiaptomus blachei, Phyllodiaptomus christineae, Eodiaptomus sanoamuangae, Neodiaptomus yangtsekiangensis, E. draconisignivomi, T. vicinus, and Heliodiaptomus elegans. Twelve species appear to be endemic to Thailand, and eight species occur only in the countries belonging to the lower Mekong River Basin (Thailand, Cambodia, Laos, and Vietnam). The uniqueness of the Thai diaptomids is a high degree of co-occurrence of four to seven species in the same localities. Comments on the taxonomic status of the species recorded are provided. In addition, the taxonomic validity of Mongolodiaptomus malaindosinensis is discussed.

Plankton variation in Río Cuarto Lake, Costa Rica (2013-2017)

Lake Rio Cuarto is a meromictic maar lake located in the low plains of northern Costa Rica. Its plankton composition has been studied several times since the decade of 1970. Yet most studies made short term surveys, and at least one study lasted for one year. Here we present data on phytoplankton and zooplankton composition from a four year study of the lake, from 2013 to 2017. Phytoplankton was studied from subsurface samples, preserved in Lugol’s solution and zooplankton from 20 m vertical hawls of a 64 um mesh net, and preserved with formaline and later transferred to 95% etanol. Phytoplankton composition included 54 taxa, most of them from the were Chlorophyta, followed by Cyanobacteria and Bacillariophyta. The most abundant were Synechococcus spp., Aphanocapsa sp. Coenochloris fotii, Chlorella sp. and Discostella stelligera. Total phytoplankton decreased from 2013 to 2017, mainly due to a decrease in Cyanobacteria. Zooplankton comprised 14 taxa, 5 cladocerans, 4 copepods, 1 diptera and 4 rotifers. The most abundant were Keratella cochlearis, Brachionus falcatus, Eubosmina tubicen and Arctodiaptomus dorsalis. There was a substitution of dominant species through time, at first (2013-2014) K. cochlearis and E. tubicen alternated in dominance, and later (2015-2016), A. dorsalis, Diaphanosoma sp. and Ceridaphnia sp. became dominant, with a return of K. cochlearis by 2017. The relationship between both components of the plankton is a complex result of the responses of individual species of both microalgae and zooplankton. However, most zooplankton taxa should be regarded as omnivores, so those relationships are not direct causal effects. The changes that occurred during the time of the study seem to be related to changes in the conditions of the lake, since its thermocline deepened with time and became more transparent. Those changes were not cyclical on an annual basis, but seemed to occur more on a long-term basis, as has been recognized earlier in the literature about tropical lakes.

“…The effects of environmental factors on the life history traits of tropical freshwater copepods are still rarely and only sporadically reported. Recent studies on the tropical calanoid Arctodiaptomus dorsalis Marsh, 1907 collected from Lake Taal (Philippines) showed that this copepod can grow to be an adult within one month, with varying survival rates of 23-67% when reared with the single algal source of Chlamydomonas reinhardtii (Tordesillas et al 2016), how-ever, the highest egg production rate was obtained under a cell concentration of 2 10 5 mL −1 at 30°C (Tordesillas et al 2018). Since food selectivity in copepods is strongly influenced by both particle quality and the abundance of alternative foods (DeMott 1986, 1989, Kiørboe 2016, the widespread distribution of copepods in tropical waters might be due to their wider utilization of available food sources in the field.…”

The freshwater calanoid copepod Mongolodiaptomus malaindosinensis is an endemic species of the lower Mekong basin, including Malaysia. The relationships between environmental factors and life history traits have been reported for many copepods, while they have never been assessed in this tropical species. Post-embryonic development time (post-EDT), body size and survival rate of M. malaindosinensis were determined under different algal concentrations of Chlamydomonas reinhardtii and Cryptomonas tetrapyrenoidosa at 25°C, to clarify the effects of algal species and carbon supply on their somatic growth and survival. Post-EDT until adult in M. malaindosinensis decreased with increasing food carbon supply regardless of the algal species tested. Although naupliar developments were the shortest at 10 4 cells mL −1 of C. reinhardtii, food shortage delayed the development time and also induced high mortality during the copepodid stages. The highest survival rate of 93% was obtained in the copepods fed on C. tetrapyrenoidosa at 5 10 4 cells mL −1 , whereas the survival rates in the remaining lower carbon supply were <23%. The most sensitive stages were the 1st copepodid stage, as indicated by high stage-specific mortalities, because of large morphological and physiological changes in this transitional stage. Prosome length of adult M. malaindosinensis positively correlated with food carbon supplies, though females were larger than males. Somatic growth rate exponentially increased with increasing food carbon supplies with a threshold at around 4.0 mgC L −1. These results suggest that tropical copepods may be adapted to higher food quantities due to their high metabolic rates under high temperature conditions.
