The presence of predators did not influence the displacement time or the proportion of food consumed by any of the two species. In the presence of predators, benthic tadpoles avoided the benthic microhabitat, increasing their time in the middle of the water column. This behavior was unexpected since the previous studies indicate that the morphology of benthic tadpoles restricts them to the bottom of water bodies. We, thus, hypothesize that such a drastic behavior change was a consequence of the real risk of predation to which the tadpoles were exposed. Our results are in accordance with the threat-sensitivity hypothesis, in which prey behave flexibly when exposed to different degrees of predation threats. Nektonic tadpoles, however, slightly increased their permanence in the water column in the presence of the same benthic predators. Therefore, we provide support for the hypothesis that predators induce greater behavioral changes in prey that exhibit patterns of microhabitat use similar to theirs.","PeriodicalId":13147,"journal":{"name":"Hydrobiologia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used Stable Isotopes (δ13C and δ15N) to classify the most abundant fishes of the Atrato River Delta (Colombia) into trophic guilds. We examined trophic niches and the relationships between the abundance of the trophic guilds (catch per unit effort) and environmental variables. The zoobenthivores were the dominant trophic guild. The isotopic niche width, based on Bayesian estimate of the standard ellipse areas, was more significant for carnivores (25.3‰2) and planktivores (24.4‰2) than for omnivores (7.8‰2) and phytobenthivores (3.1‰2). The overlap combinations showed a medium probability of isotopic overlap (≈50%) between carnivores and planktivores and between carnivores and omnivores. Isotopic niche size and overlap suggested diversity in food sources and considerable niche segregation of the fish community. Mangrove area was the main factor explaining the abundance of omnivores and zoobenthivores, supporting that the causal links between mangrove habitat and local fishery production may be explained through the trophic contribution of mangroves and mangrove-related sources. The results underscore the importance of mangrove areas in the trophic organization of fish communities and can inform strategies aimed at managing the ecosystem impacts of fishing and protecting extensive mangrove areas in the southern Caribbean.","PeriodicalId":13147,"journal":{"name":"Hydrobiologia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sediment is an active hot spot for microbial metabolism, driving the migration and transformation of elements in shallow lakes, which may control the DIC availability to influence algal spatiotemporal dynamics. Hence, we investigated the spatiotemporal changes of phytoplankton, DIC and sediment respiration rates in a eutrophic shallow freshwater lake under non-bloom conditions. There was a widespread deficiency of DIC in the lake, except the estuary. Sediment respiration was positively associated with changes in DIC concentrations, indicating that carbon metabolic activity of sedimentary microorganisms was an important inorganic carbon source for water columns. The availability of DIC in water columns regulated by sediment microbial respiration influenced the algal biomass, composition and productivity. The synergistic effects of seasonal temperature changes and sediment microbial respiration influenced the vertical distribution and migration of phytoplankton. Our results emphasized that carbon metabolic intensity of sediment microorganisms might play a key role in dynamics of phytoplankton, further impacting the spatiotemporal pattern and formation of algal bloom in eutrophic shallow freshwater lakes.","PeriodicalId":13147,"journal":{"name":"Hydrobiologia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We comparatively analyze how the mass and physiological male and female gonad investments of the broadcast-spawning intertidal Chiton articulatus in two populations from the Mexican Tropical Pacific respond to the thermal phases of cold “La Niña” and warm “El Niño.” We found that local rather than regional temperature modulates MGI intensity and breadth in this species, evidencing higher MGI levels in the southern tropical zone (Oaxaca). Male gonad investment was higher than that of females during neutral and cold phases compared to warm thermal phases. Physiological gonad investment during MGI suggests that males spawn before females, and the adult sex ratio of each population was close to unity. Our results suggest reproductive success regulation through sexual asymmetry in both mass and physiological gonad investment, modulated by temperature changes due to thermal phases. The male bias in gonad investment found under neutral to cold temperatures suggests physiological resilience in this species, especially considering its habitat and the impact of climate change· The MGI value is a phenotypic trait that varies as a function of temperature.","PeriodicalId":13147,"journal":{"name":"Hydrobiologia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141777438","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated the non-random co-occurrences of zooplankton species, which species have positive and negative co-occurrences, and which environmental factors (local and landscape) influence the species distribution and co-occurrences in Amazon lotic systems. We expected that variables related to intense changes in the landscape would influence species distribution and reduce positive and negative co-occurrences, increasing random associations. Our study was conducted in a river and twelve first- and second-order streams across three periods in the Amazon region of Brazil. We sampled zooplankton and physical and chemical variables and determined forest cover around the sampling sites. Co-occurrences were determined by probabilistic models. Total suspended solids, pH, and ammonium were the variables shaping zooplankton distribution. We observed 43 positive and six negative co-occurrences. Ammonium increased positive and negative co-occurrences and suspended solids decreased these associations. Our study provides insights into how environmental factors can alter niche availability and biotic interactions leading to different patterns of zooplankton co-occurrence in Amazon systems. This is the first study investigating such relationships in Amazon lotic systems and can help to understand risks to biodiversity and plan conservation strategies.","PeriodicalId":13147,"journal":{"name":"Hydrobiologia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141744793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We estimate a dated molecular phylogeny from the 18Sr-RNA sequence available from GenBank. We inferred the habitat ancestral state and the dynamics of the diversification rates related to assessed habitats. Our results showed that the arrival to phytotelmata habitats is recent and occurred numerous times and independently over evolutionary time, being the origin of potentially endemic ciliates after the appearance of bromeliads. Our data also revealed that the arrival of the ciliates to the phytotelma occurred through four distinct routes: (i) from a marine/brackish ancestor, (ii) a freshwater ancestor, (iii) a terrestrial ancestor, or (iv) a symbiotic ancestor. In addition, we noticed a significant increase in the diversification rates of potentially endemic ciliates to bromeliad phytotelma. Several ecological, morphological and evolutionary hypotheses help to explain these ciliates' evolutionary success. However, more studies with this group are needed to define complex hypotheses explaining such a process. It emphasizes the need to dedicate efforts to develop ecological and molecular studies with this group.","PeriodicalId":13147,"journal":{"name":"Hydrobiologia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141744638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, ecological niche modeling was employed to predict the potential distribution and assess niche overlap of two problematic gastropod species in South America: the native species Biomphalaria glabrata, which serves as a vector for schistosomiasis pathogen, and the invasive Melanoides tuberculata. Our findings revealed overlapping environmental niches between native and invasive gastropod species, with the invasive species exhibiting broader environmental requirements. The distinct environmental niches of each gastropod species translate into unique potential distribution locations in geographic space, which remain largely unchanged across current and future climatic scenarios. Additionally, we provide evidence suggesting that utilizing the invasive species as a biological control for health-related species may not be advantageous without specific management strategies. Despite niche similarities, the invasive gastropod has the potential to spread to less ideal habitats for the native species. Hence, strategies to address both native and invasive mollusks should be formulated based on empirical evidence to mitigate environmental, ecological, and health concerns.","PeriodicalId":13147,"journal":{"name":"Hydrobiologia","volume":null,"pages":null},"PeriodicalIF":2.6,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141744795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
