“…Franssen et al, 2006;Gubiani et al, 2007;Magalhaes et al, 2007). However, wetlands have been less studied (DeAngelis et al, 1997(DeAngelis et al, , 2010Ruetz et al, 2005). Understanding the role of hydrological variation in ecosystem functioning has become even more crucial with current concerns about global climate change that predict an increase of interannual variability (Coops et al, 2003;Wantzen et al, 2008).…”

“…Convergence in these three life history strategies has been recognized for Neotropical, North American and European freshwater fish (Winemiller, 1989;Vila-Gispert et al, 2002;Mims et al, 2010), and North American marine fish (Winemiller, Rose, 1992), as well as for fish communities in different latitudinal and hydrological gradients (Lamouroux et al, 2002;Tedesco, Huguery, 2006;Tedesco et al, 2008;Mims et al, 2010;Olden, Kennard, 2010). These studies emphasize the differences of fish responses to hydrological variation based on their life history strategies: periodic strategies are favored in highly seasonal drainage basins, the equilibrium strategies in hydrologically stable drainage basins, and the opportunistic strategies in habitats with high hydrologic variability (DeAngelis et al, 1997(DeAngelis et al, , 2005(DeAngelis et al, , 2010Winemiller, 1989Winemiller, , 2005King et al, 2003;Tedesco, Huguery, 2006;Tedesco et al, 2008;Olden, Kennard, 2010), but only few studies have empirically tested these predictions Mims, Olden, 2012).…”

“…Periodic hydrological variation in rivers and wetlands plays a significant role in generating responses for various biological attributes such as gonad maturation, migration, recruitment, growth and feeding (Winemiller, 1989;Gomes, Agostinho, 1997;Taylor et al, 2001;Agostinho et al, 2004;Lytle, Poff, 2004;DeAngelis et al, 2010;Hinojosa-Garro et al, 2013). The hydrological regime can fluctuate on different time scales (from days to decades) depending on regional climatic conditions (Poff et al, 1997;Coops et al, 2003).…”

Hydrological variation differently affects fish species. In the present study, the response of local populations of 13 fish local species to hydrological variation in a tropical wetland was evaluated. The objectives were to analyze the abundance response of fish species with distinct life history strategies and to assess the role of hydrological variation on fish population patterns. We found that opportunistic strategists were favored by high hydrological variation in drought periods, the equilibrium strategists were related to stable habitats, and periodic strategists were regulated by floods and temperature. However, the life history strategies identified for some species in this study do not correspond to the classification reported in other studies. Our results highlight the importance to study the abundance responses of species at local and regional scales to identify variations in life-history strategies, which can reflect local adaptations of species to hydrological changes, this is useful in order to understand and predict the responses of fish populations to the local environment.Key words: Dry season, Fish resilience, Life history strategies, Rainy season, Sian Ka´an.La variación hidrológica afecta de manera diferencial a las especies de peces. En el presente estudio, se evaluó la respuesta de las poblaciones locales de 13 especies de peces considerando la variación hídrica en un humedal tropical. Los objetivos fueron analizar la respuesta de las abundancias de las especies de peces con diferentes estrategias de historia de vida e identificar la importancia de la variación hídrica en los patrones de las poblaciones de peces. Se encontró que los estrategas oportunistas fueron favorecidos por la alta variación hídrica en los periodos de sequía, los estrategas de equilibrio se relacionaron con hábitats estables, y que los estrategas periódicos son regulados por las inundaciones y la temperatura. Sin embargo, para algunas especies las estrategias de historias de vida identificadas en este estudio no corresponden a la clasificación reportada en otros estudios. Nuestros resultados resaltan la importancia de estudiar las respuestas de la abundancia de las especies a escalas locales y regionales para identificar las variaciones en las estrategias de historia de vida, las cuales pueden reflejar adaptaciones locales de las especies a cambios hídricos, esto es útil para entender y predecir las repuestas de las poblaciones de peces a los ambientes locales.Palabras clave: Capacidad de recuperación, Estación seca, Estrategias de historia de vida, Sian Ka´an, Temporada de lluvias.

“…Alternatively, the environment can dry up completely during the period of low rainfall, creating seasonal habitats (Lake, 2003;Mas-Martí et al, 2010;Hinojosa-Garro et al, 2013). The hydroperiod restrict the spatial distribution of ichthyofauna when the water levels fall or determine the existence of a community composed of species with the ability to sustain viable populations even in seasonal habitats (DeAngelis et al, 2010).…”

Rivulidae includes non-annual fish of perennial habitats and annual fish of temporary wetlands. The objective of this research was to investigate the trophic strategy of Atlantirivulus riograndensis in a perennial environment. Sampling occurred in an environmental conservation unit in the Pampa biome, Brazil. Quantification of the diet followed the volumetric method. Consumption of autochthonous material as the main food source of the species followed the pattern of Rivulidae. Species is zooplanktonic when young. Food spectrum is broadened and insectivorousness increases with ontogeny, revealing a specialist trend in the feeding strategy of A. riograndensis. The most diverse feeding occurs in the spring and summer seasons in which the presence of larger fish was more frequent than in other seasons. The increased consumption of microcrustaceans in the fall was related to smaller individuals, captured in greater quantities in this post-reproductive period. The lowest diversity of dietary items occurs during the winter and may reflect the lower diversity of food resources available in this season or the transition from juvenile to adult diet, with consumption of autochthonous Diptera by medium sized fish.Rivulidae inclui peixes não anuais de habitats perenes e peixes anuais de alagados temporários. O objetivo desta pesquisa foi investigar a estratégia trófica de Atlantirivulus riograndensis em um ambiente perene. A amostragem ocorreu em uma unidade de conservação ambiental no bioma Pampa, Brasil. A quantificação da dieta seguiu o método volumétrico. O consumo de material autóctone como principal recurso alimentar da espécie seguiu o padrão da família Rivulidae. A espécie é zooplanctívora quando juvenil. O espectro alimentar é ampliado e a tendência à insetivoria aumenta com a ontogenia, revelando traços especialistas na estratégia alimentar de A. riograndensis. A alimentação mais diversificada ocorreu na primavera e no verão, estações em que a presença dos peixes maiores foi frequente que em outras estações. O aumento no consumo de microcrustáceos no inverno foi relacionado aos indivíduos menores, capturados em maior quantidade neste período pós-reprodutivo. A menor diversidade de itens alimentares ocorreu durante o inverno e pode refletir uma menor diversidade de recursos alimentares disponíveis nesta época do ano ou a transição da dieta de juvenil para adulto, com consumo de Diptera autóctone por peixes de tamanho médio.

“…Survival is a key determinant of population dynamics (Varley & Gradwell 1960;Buzby & Deegan 2004), and the ability for ecologists to link vital rates to environmental factors provides a powerful tool to investigate how natural populations respond to changing patterns of disturbance (Frederiksen et al 2008;Frederiksen et al 2013). Although a number of studies have begun incorporating variation in refuge quality to understand the interplay between disturbance and refuge habitats (Kobza et al 2004;DeAngelis et al 2010;Parkos et al 2011;Bond et al 2015), few directly quantify survival. Instead, most studies infer survival through changes in relative abundance over time, which can be problematic, as heterogeneity in the probability of individual detection across varying habitats creates an inherent bias (Williams et al 2002).…”

In aquatic systems refuge habitats increase resistance to drying events and are necessary for maintaining populations in disturbed environments. However, reduced water availability and altered flow regimes threaten the existence and function of these habitats. To test refuge function I conducted a capture-mark-recapture (CMR) study, integrating citizen science angler sampling into fisheries-independent methods. The objectives of this study were twofold: 1) To determine the contribution of citizen science anglers to improving CMR research, and 2.) to quantify apparent survival of Florida Largemouth Bass, Micropterus salmoides floridanus, in a coastal refuge habitat across multiple years of drying severity. The inclusion of angler sampling was determined to be an effective and feasible method for increasing capture probability. Apparent survival of Florida Bass varied among hydrologic periods with lowest survival when marshes functionally dried (< 10 cm). Overall mortality from drying events increased with the duration of marsh drying upstream.
