PONDS , *CRONBACH'S alpha , *BIOTIC communities - Abstract
The latitudinal diversity gradient predicts that tropical regions should have higher alpha, beta, and gamma diversity than temperate areas. However, only a few studies have assessed the temporal variability of the different components of diversity across climatic regions. In this study, we compare, using a spatial and temporal approach, the diversity of multiple taxa inhabiting tropical and Mediterranean temporary ponds. We sampled the biological communities of each set of ponds on three occasions during the same hydrological year. Under a spatial framework, we analyzed, alpha, beta, and gamma diversities. With a temporal approach, we compared the coefficients of variation in alpha diversity for each local community, and temporal beta diversity. Differences between regions and sampling periods were tested using generalized linear mixed models. We found higher gamma and alpha diversity in the tropical ponds, as expected given the latitudinal differences between them. However, phytoplankton and microinvertebrates from the Mediterranean region, matched or even exceeded tropical alpha diversity on some occasions. Spatial beta diversity did not differ between regions, and it showed lower values at the middle or the end of the hydroperiod in bacteria, micro‐ and macroinvertebrates and amphibians. Thus, processes homogenizing and heterogenising pond metacommunities must be balanced in both studied regions. Temporal variation in alpha and beta diversity was similar for ponds in both regions, except for macroinvertebrates and amphibians, suggesting differential effects on community variation observable only in animals with longer life‐spans, at our temporal scale of analysis.

- Abstract
A variety of organisms can colonize microplastic surfaces through biofouling processes. Heterotrophic bacteria tend to be the focus of plastisphere research; however, the presence of epiplastic microalgae within the biofilm has been repeatedly documented. Despite the relevance of biofouling in determining the fate and effects of microplastics in aquatic systems, data about this process are still scarce, especially for freshwater ecosystems. Here, our goal was to evaluate the biomass develop-ment and species composition of biofilms on different plastic polymers and to in-vestigate whether plastic substrates exert a strong enough selection to drive species sorting, overcoming other niche-defining factors. We added microplastic pellets of high- density polyethylene (HDPE), polyethylene terephthalate (PET), and a mix of the two polymers in 15 lentic mesocosms in five different locations of the Iberian Peninsula, and after one month, we evaluated species composition and biomass of microalgae developed on plastic surfaces. Our results, based on 45 samples, showed that colonization of plastic surfaces occurred in a range of lentic ecosystems covering a wide geographical gradient and different environmental conditions (e.g., nutrient concentration, conductivity, macrophyte coverage). We highlighted that total bio-mass differed based on the polymer considered, with higher biomass developed on PET substrate compared to HDPE. Microplastics supported the growth of a rich and diversified community of microalgae (242 species), with some cosmopolite species. However, we did not observe species-specificity in the colonization of the different plastic polymers. Local species pool and nutrient concentration rather than polymeric composition seemed to be the determinant factor defying the community diversity. Regardless of specific environmental conditions, we showed that many species could coexist on the surface of relatively small plastic items, highlighting how microplastics may ha

Many aquatic invertebrates that inhabit temporary ponds produce resting forms to overcome the dry period, building up the egg bank. When the wet phase returns, the resting forms hatch and the community is restored, and then pioneer species may have a major influence on how the pond community will assemble. We aimed to evaluate the diversity of an initial pond metacommunity by comparing the early active metacommunity collected in the field and the egg bank metacommunity (by carrying out a hatching experiment) of 32 Mediterranean temporary ponds. We hypothesised that both metacommunities would be similar but also that species turnover may play an important role, and that γ diversity would be similar with both approaches.After the identification and counting of rotifers and crustaceans in both metacommunities (i.e. the field vs. the experiment) we performed a Partial Triadic Analysis comparing the field metacommunity with those corresponding to each of the eight times the hatching experiment was checked for hatchlings. Furthermore, we compared the field and experimental metacommunities with a PROTEST analysis and identified the taxa responsible for differences between metacommunities with a SIMPER analysis. We assessed γ diversity using a size‐based rarefaction curve and an evenness profile and explored β diversity and its components (turnover and nestedness) for the two metacommunities.Our experimental results showed differences in the temporal pattern of emergence between groups of organisms, with copepods, rotifers, and anostracans appearing first, but ostracods and rotifers reaching the highest diversity at the end of the experiment. The active and experimental pioneer metacommunities were similar according to a Procrustes analysis. Nevertheless, β diversity was high in both metacommunities and the differences among ponds and between both assemblages were mostly explained by species turnover.Both the active and experimental pond metacommunities showed some exclusive species that may be more difficult to uncover with only one type of approach. Furthermore, the high β diversity observed indicates that each temporary pond is an important contributor to γ diversity in the metacommunity.These results show that hatching experiments provide information that is complementary to standard sampling of the active community, and consequently is a useful tool to uncover pond biodiversity.

The metacommunity concept provides a theoretical framework that aims at explaining organism distributions by a combination of environmental filtering, dispersal, and drift. However, few works have attempted a multitaxon approach and even fewer have compared two distant biogeographical regions using the same methodology. We tested the expectation that temperate (mediterranean‐climate) pond metacommunities would be more influenced by environmental and spatial processes than tropical ones, because of stronger environmental gradients and a greater isolation of waterbodies. However, the pattern should be different among groups of organisms depending on their dispersal abilities. We surveyed 30 tropical and 32 mediterranean temporary ponds from Costa Rica and Spain, respectively, and obtained data on 49 environmental variables. We characterized the biological communities of bacteria and archaea (from the water column and the sediments), phytoplankton, zooplankton, benthic invertebrates, amphibians and birds, and estimated the relative role of space and environment on metacommunity organization for each group and region, by means of variation partitioning using generalized additive models. Purely environmental effects were important in both tropical and mediterranean ponds, but stronger in the latter, probably due to their larger limnological heterogeneity. Spatially correlated environment and pure spatial effects were greater in the tropics, related to higher climatic heterogeneity and dispersal processes (e.g., restriction, surplus) acting at different scales. The variability between taxonomic groups in the contribution of spatial and environmental factors to metacommunity variation was very wide, but higher in active, compared with passive, dispersers. Higher environmental effects were observed in mediterranean passive dispersers, and higher spatial effects in tropical passive dispersers. The unexplained variation was larger in the tropical setting, suggesting a higher role for stochastic processes, unmeasured environmental factors, or biotic interactions in the tropics, although this difference affected some actively dispersing groups (insects and birds) more than passive dispersers. These results, despite our limitations in comparing only two regions, provide support, for a wide variety of aquatic organisms, for the classic view of stronger abiotic niche constraints in temperate areas compared with the tropics. The heterogeneous response of taxonomic groups between regions also points to a stronger influence of regional context than organism adaptations on metacommunity organization. [ABSTRACT FROM AUTHOR]

El concepto de metacomunidad ofrece un marco teórico que permite explicar la distribución de los organismos, englobando procesos que actúan a diferentes escalas espaciales y temporales. La selección ambiental y la dispersión son procesos clave estructurando las metacomunidades, actuando con diferentes intensidades según los ecosistemas u organismos estudiados. Sin embargo, pocos son los patrones generales que parecen emerger en las diversas revisiones y meta-análisis que se han llevado a cabo al respecto. En esta tesis estudiamos las similitudes y diferencias respecto a cómo los efectos ambientales, espaciales y temporales estructuran las metacomunidades de charcas temporales tropicales y mediterráneas. Nuestros resultados muestran que, a pesar de las diferencias ambientales entre charcas situadas en regiones distintas, la heterogeneidad ambiental puede ser similar. No obstante, las charcas mediterráneas presentaban una mayor heterogeneidad en las variables limnológicas, más locales, mientras que las charcas tropicales presentaban una mayor heterogeneidad climática, más regional y espacialmente estructurada. Encontramos efectos ambientales puros más intensos en la metacomunidad mediterránea, mientras que la metacomunidad tropical se ve más influenciada por el ambiente espacialmente estructurado. Estas diferencias en la intensidad de los efectos ambientales podrían estar relacionadas con la magnitud de la heterogeneidad limnológica y climática, mayores en la metacomunidad mediterránea y tropical, respectivamente. Los efectos espaciales puros son más relevantes en la metacomunidad tropical, sugiriendo una mayor limitación dispersiva derivada de barreras orográficas (ecológicas) más intensas en los trópicos. Estos patrones se repiten en el tiempo a lo largo de un mismo año hidrológico. No existen patrones en estos efectos de acuerdo a la capacidad dispersiva de los organismos. De hecho, las metacomunidades de organismos con dispersión activa y pasiva están estructuradas de forma similar por efectos ambientales y espaciales. Sin embargo, las diferencias entre regiones son más marcadas en los dispersores activos. Los efectos temporales puros son importantes, tanto incluso como los efectos ambientales, y especialmente en organismos de tamaño corporal intermedio. Estos efectos temporales puros son mayores en la metacomunidad mediterránea, posiblemente relacionados con sucesiones más variables a lo largo del tiempo. Por otro lado, la diversidad regional en la metacomunidad tropical, mayor que en la mediterránea, no se debe a una mayor variación temporal de la diversidad, ni a una mayor heterogeneidad espacial de las comunidades, sino que está relacionada con una mayor diversidad local. The metacommunity concept provides a theoretical framework to explain the distribution of organisms, encompassing processes acting at different spatial and temporal scales. Environmental selection and dispersal are key processes structuring metacommunities, acting with different intensities depending on the ecosystems or organisms studied. However, few general patterns seem to emerge in the various reviews and meta-analyses that have been carried out in this regard. In this thesis, we study the similarities and differences in how environmental, spatial and temporal effects structure metacommunities in tropical and mediterranean temporary ponds. Our results show that, despite environmental differences between ponds located in different regions, environmental heterogeneity may be similar. However, mediterranean ponds showed greater heterogeneity in limnological variables, which are considered more local, whereas tropical ponds showed higher climate heterogeneity, considered more regional, and spatially structured. We found more intense pure environmental effects in the mediterranean metacommunity, whereas the tropical metacommunity was more influenced by the spatially structured environment. These differences in the intensity of pure and spatially structured environmental effects could be related to differences in limnological and climate heterogeneity, higher in the mediterranean and tropical metacommunity, respectively. Pure spatial effects are more relevant in the tropical metacommunity, suggesting a greater dispersal limitation derived from more intense orographic (ecological) barriers in the tropics. These patterns are repeated in time throughout the same hydrological year. There are no patterns in these effects according to the dispersal ability of the organisms. Metacommunities of actively and passively dispersing organisms are structured similarly by environmental and spatial effects. However, differences between regions are more marked in active dispersers. Pure temporal effects are important, even as much as environmental effects, and especially in organisms with intermediate body size. These pure temporal effects are higher in the mediterranean metacommunity, possibly related to more variable successions over time. In addition, regional diversity in the tropical metacommunity was higher than in the mediterranean one. This was not caused by greater temporal variation in diversity, nor by a greater spatial heterogeneity of communities, but rather related to higher local diversity.

- Abstract
Prior research on metacommunities has largely focused on snapshot surveys, often overlooking temporal dynamics. In this study, our aim was to compare the insights obtained from metacommunity analyses based on a spatial approach repeated over time, with a spatio-temporal approach that consolidates all data into a single model. We empirically assessed the influence of temporal variation in the environment and spatial connectivity on the structure of metacommunities in tropical and Mediterranean temporary ponds. Employing a standardized methodology across both regions, we surveyed multiple freshwater taxa in three time periods within the same hydrological year from multiple temporary ponds in each region. To evaluate how environmental, spatial and temporal influences vary between the two approaches, we used nonlinear variation partitioning analyses based on generalized additive models. Overall, this study underscores the importance of adopting spatio-temporal analytics to better understand the processes shaping metacommunities. While the spatial approach suggested that environmental factors had a greater influence, our spatio-temporal analysis revealed that spatial connectivity was the primary driver influencing metacommunity structure in both regions. Temporal effects were equally important as environmental effects, suggesting a significant role of ecological succession in metacommunity structure.
