“…Greater numbers of accessory species in HP3 as well as higher species diversity, compared to HP2, supports the assumption that some rotifers appear from sediment seed bank from the surrounding flooded area following inundation (Walsh, Smith, & Wallace, ). Moreover, these results also support the premise that temporary aquatic habitats indeed do support higher rotifer biodiversity compared to permanent waterbodies (Pérez‐Bilbao, Benetti, & Garrido, ).…”

Rotifers display r‐strategy life‐histories and are adaptable to environmental disturbances. Although rotifers constitute a large proportion of zooplankton in river‐floodplain systems, the influence of hydrology on their assemblage has been poorly studied. We postulated that rotifer assemblage and grazing activities were controlled by mechanisms associated with hydrological conditions. We conducted a 5‐year study (Kopački Rit Nature Park, NE Croatia) to assess the influence of hydrology on (a) rotifer assemblage during different hydrological phases, (b) the vertical distribution of rotifer abundance, functional feeding guilds, and grazing intensity, and (c) the main drivers affecting rotifer assemblage in the floodplain lake. The results indicated that (a) during isolation, longer residence time and high phytoplankton biomass microfilter‐feeders (mIff) and macrofilter‐feeders (mAff) grazing rates were similar whereas predators (Pr) were the most efficient consumers, (b) during high flow pulses, high conductivity and variable water level governed rotifer grazing rates of mIff and mAff at a retion of 1:2 and a decline of Pr grazing activity, and (c) during the flood pulse, reduced phytoplankton biomasss still resulted in mAff and Pr domination of the community whereas mIff grazing activity remained at the same level. Under stable hydrological conditions algivorous species codominated with bacterivores and predators, suggesting an increased biodiversity and food web interactions. In contrast, throughout the inundation period, algivorous species predominated. However, differences in rotifer assemblage between normal flow and flood pulses indicated the importance of hydrology in shaping rotifer trophic structure through modifying lower trophic levels and the availability of food sources.

“…Fragaria nubicola and Pilea glaberrima was the dominant species in lentic and lotic habitats respectively. Lentic habitat supports a high diversity of freshwater plant species owing to the multiformity of landscape and habitat provided by lentic habitat (Pérez-Bilbao et al, 2015;Deacon et al, 2018). Bubíková and Hrivnák (2018) enunciated that the lentic habitats have comparatively smaller catchment areas than lotic habitats which renders them to limited exposure to detrimental anthropogenic activities.…”

Freshwater plants play a paramount role in an aquatic ecosystem. However, only limited studies have been carried out on freshwater plants. Therefore, the study aimed to assess the diversity of freshwater plants in different freshwater bodies of Punakha District, the correlation of freshwater plant species with the environmental variables, and the local community difference in freshwater plant use knowledge in Punakha district. A total of 20 water bodies were selected using a stratified sampling method. Area-based surveys were employed to assess the plant species from a total of 80 plots, each with the quadrat of 5 m x 5 m. Environmental variables such as altitude, water depth, water velocity, temperature, precipitation and evapotranspiration were measured. The study recorded a total of 72 freshwater plant species distributed among 57 genera and 37 families. Shannon-Weiner diversity index revealed high diversity of freshwater plants from ponds (H’ = 3.3) followed by ditches (H’ = 3.16), streams (H’ = 3.07) and lakes (H’ = 2.83). The study revealed the decrease of freshwater plant species with an increase in the water velocity, depth and altitude. There was a significant association between respondents’ freshwater plant use knowledge with gender (x2 (1) = 6.04, p = .014), age (x2 (1) = 13.21, p = .000) and education level (x2 (1) = 4.53, p = .003). Females and illiterate respondents with aged 31 years old and above had more knowledge on freshwater plant use compared to males and educated respondents with aged 30 years old and below.

“…Rotifera species are more numerous, but L. lunaris and Plathionus patulus are some of the most frequent in these temporary environments, which was also found by Passos (2017). Temporary ecosystems are generally small, shallow and isolated (Pérez-Bilbao et al, 2015), which results in a relatively low biodiversity (Zacharias et al, 2007;Crispim & Freitas, 2005). In a study of 29 temporary ponds in the UK, divided into permanent (which have well defined periods of flood and dry) and temporary semi-permanent (which exceptionally dry up and can spend years in flood periods), the authors found a greatly reduced number of species in the semi-permanent temporary ponds compared to the others (Collinson et al, 1995).…”

“…Temporary ponds are very common in arid and semi-arid regions (Brendonck et al, 2008;Atashbar et al, 2014) and are characterized by well defined and predictable periodic dry and flood cycles (Williams, 1996). During floods, characteristic aquatic communities develop (Pérez-Bilbao et al, 2015). Their fauna and flora has physiological, morphological and behavioral adaptations in response to flood oscillations, making these environments strong points of speciation (Williams, 1996).…”

“…As they are small, shallow and temporary, they are often considered unproductive areas where disease-transmitting insects live. This, as well as the need for agricul-tural expansion, tend to cause a reduction of these habitats (Perez-Bilbao & Garrido, 2009;Pérez-Bilbao et al, 2015). The establishment of invasive species, pollution caused by using fertilizers and pesticides, changes in hydrological functioning and climate change are some of the factors that threaten the integrity of this type of ecosystem, which can have an impact on the richness, abundance, dominance and biomass of their communities (Crossetti & Bicudo, 2005, Pérez-Bilbao et al, 2015.…”

Zooplankton community structure from tropical temporary ponds during a flood periodMany ways of measuring ecosystem biodiversity have been used. Besides taxonomic diversity, the functional diversity approach is considered highly predictive of the structure of biological communities and ecosystem processes. Temporary aquatic ecosystems have a great evolutionary and ecological importance, as they are very endemic places with rare species, often endangered by local extinction. The objective of this study was to describe the structure of the zooplankton community of eight Brazilian temporary ponds during the flood period. The organism collections and measures of environmental variables were carried out from 01/31 to 02/02/2017. As they are small and ephemeral environments, with very peculiar characteristics, both the taxonomic diversity (27 taxa) and the functional one were relatively low, suggesting convergence of the functional characteristics of the species. The zooplankton community was divided into five functional groups and the most significant functional attributes in the grouping of the species were habitat, trophic group and food habit. The functional groups were similar to the taxonomic groupings, except for raptorial carnivorous (Copepoda Cyclopoida and one Rotifera) that comprised the same functional group. In terms of biomass, two species of the Anostraca of the genus Dendrocephalus far exceeded the other groups. It was shown that the presence of these large Branchiopoda has an impact on the composition and numerical density of the zooplankton community, particularly the Cladocera, possibly due to niche overlap.
