“…The observed absence of a strong CO 2 effect on the community composition in the present study is in line with the observations in the western Baltic Sea (Thomsen et al, 2010;Nielsen et al, 2010;Rossoll et al, 2013). In these studies, the authors suggested that the plankton community is adapted to OA due to the recurrent large seasonal and daily variance of pH and CO 2 experienced by the communities in this productive low-salinity region (Thomsen et al, 2010;Nielsen et al, 2010;Rossoll et al, 2013;Almén et al, 2014). Our study region, a coastal zone in the western Gulf of Finland in the northern Baltic Sea, is a brackish environment with low salinity (∼ 5.7 ‰) and has a high fresh water run-off (∼ 111 km 3 yr −1 ; Savchuk, 2005) and a strong inter-and intra-seasonal pH variability, sometimes reaching extreme values of 9.2 and 7.4 with an average of 8.1 (Brutemark et al, 2011).…”

“…Copepods experience widely varying pH conditions on a daily basis during their vertical migration, shown in the same area as the current study (Almén et al, 2014), which may explain their tolerance to pH variations. Several studies have demonstrated that food quality of the available prey in terms of PUFA content can affect egg production, hatching success and nauplii survival in copepods (Jónasdóttir, 1994;Jónasdóttir et al, 2009;Caramujo et al, 2007).…”

Abstract. Increasing atmospheric carbon dioxide (CO 2 ) is changing seawater chemistry towards reduced pH, which affects various properties of marine organisms. Coastal and brackish water communities are expected to be less affected by ocean acidification (OA) as these communities are typically adapted to high fluctuations in CO 2 and pH. Here we investigate the response of a coastal brackish water plankton community to increasing CO 2 levels as projected for the coming decades and the end of this century in terms of community and biochemical fatty acid (FA) composition. A Baltic Sea plankton community was enclosed in a set of offshore mesocosms and subjected to a CO 2 gradient ranging from natural concentrations (∼ 347 µatm f CO 2 ) up to values projected for the year 2100 (∼ 1333 µatm f CO 2 ). We show that the phytoplankton community composition was resilient to CO 2 and did not diverge between the treatments. Seston FA composition was influenced by community composition, which in turn was driven by silicate and phosphate limitation in the mesocosms and showed no difference between the CO 2 treatments. These results suggest that CO 2 effects are dampened in coastal communities that already experience high natural fluctuations in pCO 2 . Although this coastal plankton community was tolerant of high pCO 2 levels, hypoxia and CO 2 uptake by the sea can aggravate acidification and may lead to pH changes outside the currently experienced range for coastal organisms.

“…Such experience may benefit the zooplankton species to cope with the shifting thermal regime in the water. According to Almén et al (2014), zooplankton experience widely varying conditions in their physicochemical environment on a diurnal basis. The amplitude of the fluctuations may affect the zooplankton species' ability to respond to climate change.…”

Long-term variability of zooplankton community under climate warming in tropical eutrophic man-made lake

Sunardi, Yoshimatsu T, Junianto N, Istiqamah N, DeWeber T. 2016. Long-term variability of zooplankton community under climate warming in tropical eutrophic man-made lake. Biodiversitas 17: 626-633. The climate warming is increasingly acknowledged as an important driver of lake ecosystems. However, there are no generic patterns of how the aquatic species/community responds the warming climate; instead the changes are complicated by interactions of many factors. To regard the important role of zooplankton in the lake ecosystems, this paper questions whether the climate warming affects their community structure in tropical eutrophic man-made lake. We analyzed a series of data resulted from a long water quality monitoring activities in the Cirata Lake, Indonesia. We anticipated that there would be a strong association between the climates warming with the response of zooplankton community after 19 years. Our result suggested that the lake has been becoming slightly warmer following the atmospheric temperature. Instead of decreasing, the shifting water temperature tend promotes a greater species richness, density, and diversity of the zooplankton. Relevant changes in species composition have been observed. It seems that the magnitude of the shift of the temperature, and the eutrophication status played an important role in shaping the changes of the zooplankton community structure.

“…Studies on the phenology of warm-water copepods suggest that increased temperatures can lead to increased fecundity and thereby increase population size at specific times of year (Gerten and Adrian, 2002;Wagner and Adrian, 2011). Concern has been raised that the frequency of diurnal changes in the physiochemical environment could overwhelm the adaptability of copepods (Alm en et al, 2014), and freshwater scarcity (see above) may also play a role in determining future abundance.…”

Climate change is expected to impact across every domain of society, including health. The majority of the world's population is susceptible to pathological, infectious disease whose life cycles are sensitive to environmental factors across different physical phases including air, water and soil. Nearly all so-called neglected tropical diseases (NTDs) fall into this category, meaning that future geographic patterns of transmission of dozens of infections are likely to be affected by climate change over the short (seasonal), medium (annual) and long (decadal) term. This review offers an introduction into the terms and processes deployed in modelling climate change and reviews the state of the art in terms of research into how climate change may affect future transmission of NTDs. The 34 infections included in this chapter are drawn from the WHO NTD list and the WHO blueprint list of priority diseases. For the majority of infections, some evidence is available of which environmental factors contribute to the population biology of parasites, vectors and zoonotic hosts. There is a general paucity of published research on the potential effects of decadal climate change, with some exceptions, mainly in vector-borne diseases.
