Abstract:
Clearing and staining of Gambusia holbrooki facilitated identification of juvenile fishes among the gut contents, and a feeding trial with captive Gambusia allowed assessment of gut transit time and degradation of melanotaeniid larvae. Regurgitated fishes and eggs in fixative solutions were also investigated. These techniques, extending to 12 h the post-feeding interval in which fishes may be found and differentiated among Gambusia gut contents, were tested on 631 wild-caught Gambusia collected in eastern Australia; an ingested native fish could be identified in the gut of 18 Gambusia, and a cannibalized fish in the gut of three.

Abstract:
Little is known about the learning ability of crustaceans, especially with respect to their anti-predator responses to invasive species. In many vertebrates, anti-predator behaviour is influenced by experience during ontogeny. Here, predator-naïve glass shrimp (Paratya australiensisis) were exposed to a predatory, invasive fish species, Gambusia holbrooki, to determine whether shrimp could learn to: (1) avoid the scent of Gambusia via classical conditioning; and (2) restrict their activity patterns to the night to reduce predatory encounters. Conditioned shrimp were placed in containers in aquaria containing Gambusia for 3 days during which time they could be harassed but not consumed by Gambusia. When tested in a Y-maze, conditioned shrimp showed a long delay before making a choice between Gambusia scented water and aged tap water but chose an arm at random. Control shrimp showed a brief delay in emergence and also chose at random. In a second experiment, we housed shrimp with a single Gambusia and observed their activity patterns. In the presence of Gambusia, shrimp switched from diurnal to nocturnal foraging. These results show that naïve shrimp learn to recognise novel predatory species via chemical cues and adjust their activity patterns to coincide with periods when Gambusia are inactive.

Abstract:
Defining the ecological impacts conferred by invasive fishes provides a framework for evaluating the feasibility of control efforts in invaded waterways, and for predicting the consequences of future incursions. Eastern gambusia (Gambusia holbrooki) is a remarkably successful invader of freshwater systems worldwide, with the capacity to detrimentally impact native fishes both directly (e.g. competition, predation, agonistic interactions) and indirectly (e.g. triggering trophic cascades). Here, we modelled the influence of eastern gambusia and several environmental covariates on fish species diversity, abundance and condition based on quantitative survey data collected from 93 wetlands in south-eastern Australia. We predicted that small-bodied, wetland specialist species sharing dietary- and habitat-niches with eastern gambusia would be most severely impacted, and that environmental stressors associated with wetland drying during late summer would magnify these impacts. Eastern gambusia influenced the occurrence, abundance and/or body condition of most common wetland species; however, the direction and level of impact appeared dependent on both biotic and environmental forces. From these results, we postulate that generalist life-history strategies that permit niche-segregation may release some native species from competitive/predatory pressures, allowing coexistence with eastern gambusia in resource-limited, environmentally harsh habitats, whilst specialist species that occupy narrower ecological niches may be less resistant.

Abstract:
The introduced mosquitofish (Gambusia affinis holbrooki) is a pest species in Australia and has been implicated in the decline of populations of native fishes and anurans. However, few quantitative data exist regarding interactions between Gambusia and native aquatic fauna. We used replicated laboratory experiments to investigate predation by G. a. holbrooki on eggs, hatchlings and tadpoles of native (Limnodynastes ornatus) and non-native (Bufo marinus) anurans. Our aims were to determine (1) whether the susceptibility of anurans to predation by G. a. holbrooki changes during larval development, and (2) the potential for G. a. holbrooki as a predator of the introduced toad B. marinus. Gambusia were significant predators of all aquatic life-history stages of L. ornatus, but were significant predators of B. marinus only at the hatchling stage. When offered both species simultaneously, Gambusia consumed tadpoles of L. ornatus but avoided those of B. marinus. The differences between the responses of Gambusia to L. ornatus and B. marinus are probably due to differences in palatability and toxicity of eggs, hatchlings and tadpoles of these species. The results indicate that G. a. holbrooki is unlikely to significantly affect larval populations of B. marinus via predation. However, Gambusia has the potential to significantly affect larval populations of L. ornatus in natural water bodies where these species co-occur.

Full text
Abstract:
The red-finned blue-eye (Scaturiginichthys vermeilipinnis) is endemic to a single complex of springs emanating from the Great Artesian Basin, Australia. The species has been recorded as naturally occurring in eight separate very shallow (generally <20 mm) springs, with a combined wetland area of ~0.3 ha. Since its discovery in 1990, five red-finned blue-eye (RFBE) populations have been lost and subsequent colonisation has occurred in two spring wetlands. Current population size is estimated at <3000 individuals. Artesian bores have reduced aquifer pressure, standing water levels and spring-flows in the district. There is evidence of spatial separation within the spring pools where RFBE and the introduced fish gambusia (Gambusia holbrooki) co-occur, although both species are forced together when seasonal extremes affect spring size and water temperature. Gambusia was present in four of the five springs where RFBE populations have been lost. Four out of the five remaining subpopulations of RFBE are Gambusia free. Circumstantial evidence suggests that gambusia is a major threat to red-finned blue-eyes. The impact of Gambusia is probably exacerbated by domestic stock (cattle and sheep), feral goats and pigs that utilise the springs and can negatively affect water quality and flow patterns. Three attempts to translocate RFBE to apparently suitable springs elsewhere within the complex have failed. Opportunities to mitigate threats are discussed, along with directions for future research to improve management of this extremely threatened fish and habitat.

Abstract:
By acting as novel competitors and predators, a single invasive species can detrimentally affect multiple native species in different trophic levels. Although quantifying invasive effects through single-species interactions is important, understanding their effect on ecosystems as a whole is vital to enable effective protection and management. This is particularly true in freshwater ecosystems, where invasive species constitute the single greatest threat to biodiversity. Poeciliid fishes of the genus Gambusia are among the most widespread invasive species on earth. In the present study of lentic ecosystems (i.e. lakes), we first showed that Gambusia alter zooplankton community composition and size distribution, likely through size-selective predation. Second, we demonstrate that benthic macroinvertebrate communities significantly differ between sites with and without invasive Gambusia. The presence of Gambusia appears to reduce leaf-litter decomposition rates, which is likely an indirect effect of reductions in detritivore abundances. Reductions in decomposition rates found in the present study suggest that through trophic cascades, invasive Gambusia is able to indirectly alter ecosystem functions. The study has highlighted that the widespread effects of invasive aquatic species are able to permeate through entire ecosystems, being more pervasive than previously recognised.

Abstract:
Abstract Considerable previous research has focused on predator-associated semiochemicals and how they affect mosquito oviposition behavior. However, most of this work has been done without taking into consideration either the natural density of the predators or how other semiochemicals in aquatic environments might affect the responses of gravid mosquitoes. The influence of mosquitofish density, source water (tap vs pond), presence of freshly laid egg rafts, and removal of a putative source of semiochemicals (bacteria) on oviposition by Culex tarsalis Coquillett (Diptera: Culicidae) was studied in laboratory bioassays. Culex tarsalis females were deterred from laying egg rafts on water that contained semiochemicals associated with Gambusia affinis (Baird & Girard), but this deterrence was not strongly associated with the density of fish used to condition aged tap water. The number of egg rafts laid onto Gambusia-exudate water made with either tap water (density &lt; 1 fish per liter) or pond water was typically ≥ 50% of that onto water that did not house mosquitofish. Gravid mosquitoes tested individually did not reduce oviposition onto Gambusia-exudate water as compared to controls. Likewise, oviposition by females with ablated wings did not differ significantly between Gambusia-exudate water and controls. Oviposition onto filter-sterilized Gambusia-exudate water was reduced relative to unfiltered water, suggesting that semiochemicals deterring egg-laying were still present after bacteria were removed. Taken together, these findings suggest that the responses of gravid Cx. tarsalis to chemicals from habitats containing mosquitofish are complex and the origin of the semiochemicals present in the Gambusia-exudate water needs to be elucidated.

Abstract:
Gambusia holbrooki is an invasive predatory poeciliid fish in wetlands of south-eastern Australia, where it coexists with the native waterbug Anisops thienemanni (Notonectidae). Gambusia has been shown to produce trophic cascades, leading to increased algal biomass following invasion, whereas these effects relative to the often-dominant invertebrate predator Anisops are unknown. Given its flexible diet, we predicted that Gambusia would feed more broadly than Anisops, thereby reducing the abundance of zooplankton grazers, and increasing chlorophyll a. We tested this hypothesis in experimental 110-L wetland mesocosms, using Gambusia and Anisops alone and in combination, in addition to no-predator treatments. We ran two experiments lasting 91 and 35 days, respectively. Both fish and macroinvertebrates generated weak trophic cascades, resulting in minor increases in chlorophyll a above concentrations in control treatments. Gambusia, in lowering total zooplankton abundances, triggered a larger, although still relatively small, algal response relative to Anisops. Impacts of both predators on dominant invertebrate grazers (e.g. Simocephalus spp., copepod nauplii) were similar, although Anisops was associated with an increase in ostracod (Newnhamia sp.) numbers. The similar trophic role of the two predators on algae was unexpected, given their different effects on planktonic communities and their very different taxonomic positions and zoogeographic origins.

Abstract:

The study of contemporary evolution and eco-evolutionary dynamics is classically defined in terms of genetic evolution, but the actual suite of processes driving contemporary trait change is likely much more complex than often credited. This dissertation considers additional mechanisms of trait change that might be important to an emerging model system for study of contemporary evolution and eco-evolutionary dynamics. Specifically, the research focuses on phenotypically plastic and demographic trait variation in Eastern and Western Mosquitofish (Gambusia affinis and G. holbrooki) facing the major ecological gradient of predation risk. Plasticity experiments employed a common-garden rearing design to manipulate fish predator cues experienced by individuals, their parents, or their grandparents and in turn quantify reaction norms in mosquitofish size, shape, and behavior. The two species of mosquitofish showed divergent plastic responses in behavior, with the relatively bolder G. holbrooki becoming even bolder in response to predator cues. In contrast, males and females within species showed parallel behavioral responses. Despite strong sexual dimorphism, both sexes and both species showed parallel patterns of plasticity toward streamlining of body shape when exposed to predators. Interestingly, mosquitofish also showed evidence of transmitting predator cues across generations, where female G. affinis become shyer and more streamlined when their parents or grandparents experienced predators. In contrast, male G. affinis showed little evidence of transgenerational plasticity and appear to rely more heavily on their own experience. Another set of field surveys and experiments with G. hoibrooki considered the potential role of sexual dimorphism and demographic variation in sex ratios as another form of trait variation with possible community and ecosystem consequences. Natural population surveys revealed female-biased sex ratios and higher primary production in the absence of predators. Mesocosm experiments suggested males and females differed in dietary preferences and that both sex ratio and density influence community responses. Although these findings support a need to expand the current eco-evolutionary synthesis to mechanisms beyond just genetic evolution, they also support some general patterns in these mechanisms and ways in which they might work with evolution to produce an even more dynamic interaction of ecology and trait change in nature.

Abstract:
This thesis aims to contribute to the understanding of the invasive success of two invasive fishes (Gambusia affinis and G. holbrooki). We reviewed four Internet databases and the literature to clarify their introduction history and geographical distribution, establish their introduction routes, and analyse predictors of their invasive success. A meta-analysis of the ecological impacts of mosquitofishes shows that the overall impact is: i) similar for the two species; ii) clear and strong for fish, macroinvertebrates, amphibians, and some zooplanktonic groups and more variable for taxa at lower trophic levels and for ecosystem features; iii) general for the number of aggressive acts received and decreases in density and biomass but more variable for other response variables; and iv) highly heterogeneous and context-dependent on a number of features. We estimated the mean critical swimming speed (Ucrit) of G. holbrooki as 14.11 cm s-1, which is lower than for many other fish of similar size and confirms that this species is limnophilic and its invasive success might be partially explained by hydrologic alteration. However, we demonstrate that Ucrit and maximal metabolic rate vary markedly with fish size and sex, with males having much higher values for the same weight, and thus probably being more resistant to strong water flows.
Aquesta tesi té com a objectiu contribuir a millorar la comprensió de l'èxit invasor d'aquests dos peixos (Gambusia affinis and G. holbrooki). Es van revisar quatre bases de dades d'Internet i la bibliografia per aclarir la seva història d’introducció i distribució geogràfica, establir les rutes d'introducció i analitzar els predictors del seu èxit invasor. Una meta-anàlisi de l'impactes ecològics de les gambúsies mostra principalment que l'impacte global és: i) similar per a les dues espècies; ii) clar i fort per a peixos, macroinvertebrats, amfibis, i alguns grups de zooplàncton i més variable per als tàxons de nivells tròfics més baixos i a nivell d’ecosistema; iii) general per al nombre d'agressions rebudes i la disminució de la densitat i la biomassa, però més variable per altres variables; i iv) altament heterogeni i dependent del context per una sèrie de característiques. Hem estimat la velocitat crítica de natació mitjana (Ucrit) de G. holbrooki com 14.11 cm s-1, que és inferior a la de molts altres peixos de mida similar i confirma que aquesta espècie és limnòfila i el seu èxit invasor parcialment s'explica per l'alteració hidrològica. No obstant això, vam demostrar que Ucrit i la taxa metabòlica màxima varien notablement amb la mida i el sexe dels peixos, amb valors molt més alts als mascles que a femelles del mateix pes, els quals deuen ser per tant menys vulnerables a cabals forts.

Abstract:
Mosquitofish (Gambusia holbrooki) are native to the southeastern United States but invasive elsewhere, and are dominant predators in many ecosystems that they inhabit. Information on dispersal behavior will help better understand and predict mosquitofish metapopulation dynamics and invasions. I experimentally tested dispersal behavior of individual mosquitofish under a range of laboratory conditions relevant to field situations. Preliminary experiments showed that gender, lighting conditions, hunger and acclimation time did not significantly affect net dispersal rate. Power analysis based on this preliminary experiment determined that 6 replicate fish were sufficient for each subsequent experiment; I used 24 fish, and each fish was tested one time. Three factors that potentially could affect net swimming rate were tested: habitat of origin (permanent vs. temporary waters), water depth (3-24 mm), and the interaction between water depth and leaf litter type (upland and wetland). Fish from a temporary pond dispersed significantly faster than fish from a permanent pond, and fish dispersed significantly faster in deeper water than in shallower water. However, leaf litter significantly inhibited fish dispersal at all depths tested. Based on these experiments, G. holbrooki disperse more readily through relatively open and deeper (several centimeters) pathways between habitats such as roadside ditches, drainage canals and trails in flooded conditions. My results are useful for understanding mosquitofish dispersal behavior based on the abiotic and biotic factors examined in this experiment. I predict that mosquitofish can spread from a point of introduction at about 800 m per day, given and unobstructed path of only > 6 mm depth.

Projeto de Pós-Graduação/Dissertação apresentado à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Ciências Farmacêuticas
O interesse crescente dos estudos ecotoxicológicos nas várias classes farmacoterapêuticas tem sido o reflexo da frequente deteção destes compostos nos ecossistemas aquáticos. Esta exposição pode resultar em alterações adaptativas dos indivíduos expostos, como modificações a nível tecidular ou ativação de mecanismos antioxidantes, podendo estas ser monitorizadas de modo a determinar o impacto destes compostos nos organismos e respetivos ecossistemas. Dentro destes compostos destacam-se os antibióticos como sendo um grupo largamente utilizado na medicina humana e veterinária, resultando na sua frequente deteção nos compartimentos aquático. A tetraciclina é o antibiótico com a segunda maior taxa de deteção a nível ambiental, sendo utilizado largamente para o tratamento de patologias em humanos e animais. Na medicina veterinária, o uso dos antibióticos é ainda alargado ao tratamento profilático de infeções e promotor de crescimento. Com o interesse de determinar os potenciais efeitos ecotoxicológicos da tetraciclina em peixes, efetuou-se uma exposição aguda (96 h) de Gambusia holbrooki a concentrações crescentes deste composto (5, 50 e 500 ng/l) e pesquisou-se eventuais modificações tecidulares das brânquias e do fígado, bem como alterações da atividade das enzimas antioxidantes e a existência de danos lipoperoxidativos. O estudo da atividade enzimática permitiu averiguar quanto à presença de uma resposta de stress oxidativo (atividades das enzimas glutationa-S-transferases no fígado e nas brânquias, e a catalase no fígado), e neurotoxicidade (atividade da acetilcolinesterase no tecido nervoso). A quantificação de TBARS no músculo permitiu determinar a ocorrência de danos lipoperoxidativos. Os resultados obtidos sugerem uma relação causa-efeito entre a concentração de tetraciclina usada e as alterações histológicas nas brânquias e a atividade enzimática alterada, nomeadamente nas enzimas catalase no fígado e glutationa-S-transferases nas brânquias, sugerindo assim que este composto tem uma atividade pro-oxidante. Assim, nas brânquias as células poderão já ter entrado em stress oxidativo, o que levou a alterações histopatológicas detetáveis. No entanto, ao nível do fígado, e nas concentrações utilizadas no presente estudo, não foram observados danos histológicos significativos. The increasing number of ecotoxicological studies performed with several drugs is a natural consequence of the increasingly frequent detection of these compounds in the aquatic ecosystems. This exposure can result in adaptive changes of individuals, such as tissue alterations or activation of antioxidant mechanisms, which can be monitored to determine the impact of these compounds on the aquatic organisms and ecosystems. Antibiotics stand out as a group widely used in human and veterinary clinic, resulting in its detection in the aquatic environment. Tetracycline is the antibiotic with the second highest level of detection in the environment. It is widely used for human and veterinary treatment of infections, and as a prophylactic treatment of infections and growth promoter on animals. To determine the potential ecotoxicological effects of tetracycline on fish, Gambusia holbrooki individuals were exposed during 96 h to increasing concentrations of this compound (5, 50 and 500 ng/l) and histological alterations in gills and liver, changes in antioxidant enzyme activity and lipoperoxidative damage were recorded. The enzymatic study allowed assessing the presence of an oxidative stress response (glutathione S-transferases in the liver and gills, and catalase in the liver) and neurotoxicity (head acetylcholinesterase). The quantification of TBARS in muscle also allowed the assessment of lipoperoxidative damage. The results indicate a cause-effect relationship between the concentration of tetracycline used and the detected histological and enzymatic alterations in the liver and gills, suggesting that this compound has a pro-oxidative activity.

Les travaux présentés dans le cadre de notre travail de thèse nous ont permis d'évaluer les potentialités d'utilisation de la gambusie, poisson pœciliidœ, en écotoxicologie aquatique expérimentale dans une perspective d'analyse des effets des xénobiotiques à différents niveaux d'organisation biologique incluant la population. Les résultats obtenus nous ont permis de constater que : le 4-NP est activement métabolisé par la gambusie ; la différenciation sexuelle et la croissance des jeunes stades de gambusie sont altérées lors des expositions au 4-nonylphenol et à la 17α -ethynylœstradiol, se traduisant par une altération des processus de gamétogenèse ; l'étude conduite en mésocosmes lentiques au niveau des populations a permis de révéler d'une part, qu'il est possible de travailler expérimentalement au niveau des populations avec cette espèce et que, par ailleurs, les effets constatés au niveau des individus lors des expositions en laboratoire se traduisent, pour partie, au niveau des populations. Les informations obtenues permettent donc d'émettre l'hypothèse que la gambusie pourrait constituer un modèle biologique à retenir dans le cadre des procédures d'évaluation du risque lié à l'utilisation de xénobiotiques, d'une part du fait de la sensibilité des réponses observées à des concentrations en polluants proches de celles détectées dans l'environnement, d'autre part du fait de son utilisation possible dans différents contextes expérimentaux permettant des approches intégratives des effets des toxiques (de la cellule à la population)
The results of our study were used to evaluate the abilities of the mosquitofish, Gambusia holbrooki, in the perspective of analysis of xenobiotics effects at different level of biological organization including population. Our results showed that : 4-n-nonylphenol is biotransformed by mosquitofish ; sexual differentiation and growth of larvae were impaired during a 4-nonylphenol and 17α -ethynylestradiol exposure. These effects were persistent ; Gametogenesis of adults were impaired during a 4-nonylphenol exposure ; Mesocosms study showed that it is possible to conduct experimental study at the population level with this species and that effects observed in laboratory are partly translated at the population level. So all this results can allow us to hypothesize that mosquitofish might be an interesting model in risk assessment process concerning the xenobiotic use. Indeed, on the other hand we have showed that biological responses were observed at environmental concentrations of xenobiotics and in the other hand we have showed that it was possible to use this species in different experimental context that permit integrative approach of xenobiotics effects (from the cellular level on the population level)

Full text
Abstract:
Sexual conflict occurs when individuals of one sex express traits that reduce the fitness of their mates. Males of many species harass females to gain copulations, which benefits males by increasing the number of offspring they sire but imposes energetic and opportunity costs on the females they harass. This thesis examined the fitness costs of sexual harassment to females, the energetic costs of mating to males, and the factors influencing the intensity of male competition for mates in the western mosquitofish Gambusia affinis. I quantified male and female behavior, four female fitness components (number of offspring per female, embryo number, growth, and survival), and an index of male body condition in response to changes in operational sex ratio (experiment 1) and male and female density (experiment 2). I found that a strong, negative effect of female density on female fitness overwhelmed any potential costs of male harassment, suggesting that ecological interactions between females may play a larger role in determining female fitness than conflict between the sexes. Agonistic chases and displays between males increased as the operational sex ratio increased (became male-biased), while the number of copulations males attempted decreased. This inverse relationship suggests a tradeoff between interfering with other males and attempting additional copulations with females. Increases in chases between males were largely due to changes in female density, but not male density, suggesting that the availability of females determines whether males escalate contests with other males. In contrast, the number of displays between males depended varied with male density but did not female density. This difference between chases and displays is likely due to their difference in function; chases are performed to prevent other males from mating while displays are used to assess male competitors. I did not detect any energetic cost of mating to males.

Specifically, the degree to which species-specific traits may help us predict invasion success is a core issue in the field. My research examined a series of traits and asked whether they were good predictors of invasion success, particularly establishment success. I compared traits among four species of the poeciliid fish Gambusia, two of them highly invasive (G. affinis and G. holbrooki) and two of them non-invasive (G. hispaniolae and G. geiseri).I examined abiotic tolerances, feeding behavior, behavioral responses to novel predation and competition, life histories, and dispersal tendencies. I found the invasive Gambusia species to be more tolerant of low temperatures and to exhibit higher feeding rates and dispersal tendencies than non-invasives. Invasive species were more likely to respond appropriately to novel predation by reducing foraging and activity level and by increasing refuge use, and less likely to show lower foraging success when faced with competitors. Invasives exhibited higher fecundity and juvenile growth rates, and consequently reached maturity sooner than non-invasives. I found no differences in the species' diet breadth or aggressiveness.I then simulated the invasions of simplified pond communities and measured establishment success (with and without novel competitors) and community impact by tracking population trajectories over several months. As predicted from the trait comparisons, I found that in both simulations invasive Gambusia outperformed non-invasives by achieving andvmaintaining larger populations. In the first experiment, only invasive Gambusia were able to successfully establish (non-invasive populations had zero survival). In the second experiment, invasive Gambusia populations were better able to cope with competition and had greater community impact on lower trophic levels than the non-invasives.Overall, species traits were good predictors of establishment success. A species' ability to cope with the abiotic conditions of the invaded community seemed particularly important to whether or not establishment occurred in the study communities. Life history traits and the species' ability to cope with biotic interactions were important to determining the level of establishment species achieved if invaders survived the novel abiotic element.

Abstract:
<i>Abstract.</i>—We document a simple electrofishing-only monitoring program for assessing fish assemblages across large spatial extents. First, we demonstrate the justification for using only electrofishing for the monitoring. Second, we demonstrate the usefulness of having a well-designed surveillance-monitoring program in place to demonstrate the effect of landscape disturbances. Implementing electrofishing alone means that multiple sites can be sampled in a single day and there is no need to return to clear nets or traps within a sampling site. Whereas electrofishing alone does not return full species lists within sampled sites, we demonstrate that when data are aggregated up to the watershed or catchment extent, more than 90% of species are included. Analyses that do not require a census of species, such as bioassessment of river health can be readily carried out using electrofishing data. The Murray–Darling basin, Australia, was sampled with the recommended large-extent electrofishing program between 2004 and 2012, a period that saw the region subjected to large-scale variations in river flow levels spatially and temporally. We fit generalized additive models to the electrofishing data in conjunction with river flow data to document large-extent relationships between fish species occurrence and relative flow levels for the previous 3 d, 3 months, or 3 years. We found that several small-bodied species, Eastern Mosquitofish <i>Gambusia holbrooki</i>, Flathead Gudgeon <i>Philypnodon grandiceps</i>, and Australian Smelt <i>Retropinna semoni</i>, were more likely to be collected when conditions were drier in the past 3 d to 3 months, whereas common medium and large-bodied species were less likely to be collected when flow was lower over the previous 3 months to 3 years.

Abstract:
Climate and hydrology are major drivers of ecosystem structure and function, particularly in arid and semi-arid ecosystems. Understanding changes in climate, groundwater, streamflow, and water quality is central to assessing the condition of park resources. This report combines data collected on climate, groundwater, and springs at Big Bend National Park (NP) to provide an integrated look at climate and water conditions during water year (WY) 2019 (October 2018–September 2019). However, this report does not address the Rio Grande or its tributaries. Annual precipitation was higher than normal (1981–2010) for Big Bend NP at four of the five National Oceanic and Atmospheric Administration Cooperative Observer Program weather stations: 111% of normal for Chisos Basin, 122% of normal for Panther Junction, 155% of normal for Persimmon Gap, and 124% of normal for Rio Grande Village. Castolon had 88% of normal annual precipitation. All five stations had higher than normal rainfall in October and December, while rainfall totals were substantially below normal at all stations in November, February, and March. Monthly precipitation totals for April through September were more variable from station to station. Mean monthly maximum air temperatures were below normal in the fall months, with Panther Junction as much as 7.5°F below normal in October. Monthly temperatures from January through July were more variable. Temperatures in August and September were warmer than normal at every station, up to +9.4°F at Rio Grande Village and +8.7°F at Chisos Basin in July. The reconnaissance drought index values indicate generally wetter conditions (based on precipitation and evaporative demand) at Chisos Basin since WY2016 and at Panther Junction and Persimmon Gap since WY2015, except for WY2017. This report presents the manual and automatic groundwater monitoring results at nine wells. Five wells had their highest water level in or just before WY2019: Panther Junction #10 peaked at 99.94 ft below ground surface (bgs) in September 2018, Contractor’s Well peaked at 31.43 ft bgs in November 2018, T-3 peaked at 65.39 ft bgs in December 2018, K-Bar #6 Observation Well peaked at 77.78 ft bgs in February 2019, and K-Bar #7 Observation Well peaked at 43.18 ft bgs in February 2019. This was likely in response to above normal rainfall in the later summer and fall 2018. The other monitoring wells did not directly track within-season precipitation. The last measurement at Gallery Well in WY2019 was 18.60 ft bgs. Gallery Well is located 120 feet from the river and closely tracked the Rio Grande stage, generally increasing in late summer or early fall following higher flow events. Water levels in Gambusia Well were consistently very shallow, though the manual well measurement collected in April was 4.25 ft bgs—relatively high for the monitoring record—and occurred outside the normal peak period of later summer and early fall. The last manual measurement taken at TH-10 in WY2019 was 34.80 ft bgs, only 0.45 ft higher than the earliest measurement in 1967, consistent with the lack of directional change in groundwater at this location, and apparently decoupled from within-season precipitation patterns. The last water level reading in WY2019 at Oak Springs #1 was 59.91 ft bgs, indicating an overall decrease of 26.08 ft since the well was dug in 1989. The Southwest Network Collaboration (SWNC) collects data on sentinel springs annually in the late winter and early spring following the network springs monitoring protocol. In WY2019, 18 sentinel site springs were visited at Big Bend NP (February 21, 2019–March 09, 2019). Most springs had relatively few indications of natural and anthropogenic disturbances. Natural disturbances included recent flooding, drying, and wildlife use. Anthropogenic disturbances included flow modifications (e.g., springboxes), hiking trails, and contemporary human use. Crews observed one to seven facultative/obligate wetland plant...
