    Abstract Molecular data is useful to determine the taxonomic identity and origin of invasive species. A reliable identification and a complete reference database are key for the adequate management of invasive species. South American suckermouth armored catfish (Pterygoplichthys spp.) are invasive species that cause severe environmental and socioeconomic impacts. Although different species (Pterygoplichthys pardalis and Pterygoplichthys disjunctivus), and possibly hybrids, have been identified based on ventral spots’ patterns, there remains taxonomic uncertainty regarding the Pterygoplichthys spp. individuals that are becoming invasive. We used genetic data to make inferences about the number of invasion events and found that there were one or few introduction events, followed by rapid spread and population growth. When we analyzed environmental variation of the sampling sites (based on physico-chemical properties), we observed both environmental differentiation between basins and environmental homogeneity within one of the studied river basins. We then analyzed the morphological variation between morphotypes and found that in addition to the variation in the ventral patterns, we observed size differences between individuals from different basins. We amplified the CYTB and COI mitochondrial DNA regions and found a unique haplotype which is shared across the sampled basins. Finally, we found that all the suckermouth armored catfish in the different basins were P. pardalis or of hybrid origin, and the lack of diversity in the mitochondrial DNA suggested a common origin. Our study highlights that combining genetic, morphological and ecological data provides complementary evidence to understand the introduction and invasion process.

    Abstract Despite mollusk species play important ecological functions in estuaries, most studies of their assemblage’s variations are based on traditional taxonomical approaches. Biological trait analysis is used in the present work to explore the relationships of the functional composition of mollusks with the environmental gradient along a coastal lagoon of the Southern Gulf of Mexico. Sampling was conducted monthly during a year in soft bottoms and subtidal stilt roots of red mangrove at six sampling sites along the lagoon. In total 24 mollusc species were collected and fitted to a particular category of three biological traits. Spatio-temporal variability of the functional composition of molluscs and their relationships with environmental variables were assessed using three approaches. Functional variations of the molluscan assemblages were detected along the lagoon using the three approaches, showing significant correlations to salinity. Nonetheless, the functional groups (FG) and the community weighed (CWM) mean traits approaches showed a clearer spatial pattern of the functional composition than the functional diversity (FD) approach The FG and the CWM approaches used in the present study could help to broadening the ecological studies of the estuarine systems of the Gulf of Mexico, particularly those aimed to assess the relations between the biological components and environmental variables in order to assess functioning of these ecosystems.

    Abstract Land use change threatens the ecological integrity of tropical rivers and streams; however, few studies have simultaneously analyzed the taxonomic and functional responses of tropical macroinvertebrates to riparian forest conversion. Here, we used community structure, functional diversity, and stable isotope analyses to assess the impacts of riparian deforestation on macroinvertebrate communities of streams in southern Mexico. Monthly sampling during the dry season was conducted in streams with riparian forest (forest streams), and in streams with pasture dominating the riparian vegetation (pasture streams). Samples were collected for water quality (physical-chemical variables, nutrient concentrations, and total suspended solids), organic matter (leaf litter abundance and algal biomass), and macroinvertebrate abundance and diversity. Higher temperature, conductivity, suspended solids, and chlorophyll a were detected in pasture streams, while nitrate concentrations and leaf litter biomass were greater in forest streams. Macroinvertebrate density was higher in pasture sites, while no differences in taxonomic diversity and richness were found between land uses. Functional evenness was greater in forest streams, while richness and divergence were similar between land uses, despite differences in taxonomic composition. Environmental variables were associated with taxa distribution but not with functional traits, suggesting current conditions still promote redundancy in ecological function. Isotopic analyses indicated consumers in pasture streams were enriched in ¹³C and ¹⁵N relative to forest streams, potentially reflecting the higher algal biomass documented in pasture systems. Isotopic niches were broader and more overlapped in pasture streams, indicating more generalist feeding habits. No significant losses of taxonomic or functional diversity were detected in pasture streams. However, changes in trophic ecology suggest landscape-level processes are altering macroinvertebrate feeding habits in streams. The changes we observed in habitat, water quality, and macroinvertebrate community were related to the removal of the riparian vegetation, suggesting the structure and function of the focal systems would benefit from riparian restoration.

    Abstract Molluscs are an important component of the macrofauna at coastal lagoons and a relevant invertebrate group used as an ecological indicator of environmental impacts on these ecosystems. In this study, we used a multivariate approach to assess spatial distribution changes of molluscan assemblages along a salinity gradient in four habitats from a tropical coastal lagoon. Throughout 1 year, we collected samples at six sites in four identified habitats: i) muddy bottom near a fringing mangrove (MAN), ii) mangrove (Avicennia germinans) roots (RAI), iii) sandy-muddy bottom (ARE) and iv) submerged aquatic vegetation (VAS). We identified 29 molluscs species. The gastropods Neritina virginea and N. reclivata were the dominant species in the lagoon and bivalves Rangia flexuosa, Ischadium recurvum, and Crassostrea virginica occurred in all habitats and sites. Greater species richness was found during the rainy season and in the VAS habitat. Molluscan assemblages varied among seasons, habitats, and sites nested within habitats. Environmental variables that best explained seasonal molluscan assemblages were temperature and turbidity; along the lagoon, the best variables that explained molluscan assemblages were salinity and dissolved oxygen. This study supports the argument that preventing habitat loss or habitat conversion is an important issue to be considered for molluscan conservation at estuarine ecosystems.

    Abstract The study of the populations of the mexicanus group has been abandoned for the last 60 years, and there are few records of its species. This study updated the records of the populations of the mexicanus and pilosimanus groups present in the state of Tabasco. The crayfish were collected with otter trawls and traps in the Grijalva and Usumacinta sub-basins throughout an annual cycle, during the seasons of minimum (MII) and maximum (MAI) flooding. The specimens were identified following the conventional taxonomic criteria, and they were measured and sexed as male (MFI), at rest (MFII) and female (H). A total of 386 specimens were collected: 44 specimens of Procambarus (Austrocambarus) acanthophorus Villalobos, 1948; 40 specimens of P. (A.) zapoapensis Villalobos, 1954; 8 P. (A.) veracruzanus Villalobos, 1954; 5 P. (A.) ruthveni Pearse, 1911, and 289 specimens of P. (A.) llamasi Villalobos, 1954. Procambarus (Austrocambarus) llamasi was distributed exclusively in the subregion Ríos, in wetland habitats subject to seasonal flooding, and the other species were found in the subregion Sierra in agricultural and hilly areas. New records and extended distribution ranges of cambarids of the state of Tabasco are presented.

    Title translation Avifauna in silvopastoral systems in the Mesoamerican Biological Corridor, Tabasco, México.
    Abstract Silvopastoral systems support local ecological and economical features as they enhance conservation of floral and faunal communities. As other animal communities, avifauna may be a good representative of habitat alterations, both as the species and functional levels. In order to attend the initiative of Mesoamerican Biological Corridor initiative (CBM) in the state of Tabasco, we studied the diversity of birds in two silvopastoral systems: scattered trees in pastures (ADP), and trees in boundary-hedgerows (AL). For this, we applied the fixed radius counting point method in three priority sites in Tabasco's CBM during the dry and wet season of 2011, and a total of 56, 60 and 62 points were evaluated in Huimanguillo, Tenosique and Tacotalpa, respectively. We observed 2 084 individuals of 154 species (79-89% of expected diversity) and 36 bird families. We detected 92, 87 and 85 species in Huimanguillo, Tenosique and Tacotalpa, respectively, including 35 protected species, of which 23, 19 and 16 in each locality, respectively. All sites showed high diversity (H' ≥ 3.20), low species dominance (D ≥ 0.08) and high equitability (J ≥ 0.77). Species composition showed differences between sites, being most similar Tacotalpa and Tenosique. Ten species were considered characteristic for sites. Although the silvopastoral system did contain protected species, the low diversity and the early successional character of the arboreal components were not attractive to frugivorous bird species. Diversification with native trees can improve the systems to create a complementary habitat and to increase landscape connectivity. The management of silvopastoral practices on cattle dominated landscapes in Tabasco could improve its ecological quality, and thus achieve the CBM's objectives ofbiodiversity conservation combined with human economic activities.

    Title translation Presence and spatio-temporal habitat characterization of Dermatemys mawii (Testudines: Dermatemydidae) in the Grijalva-Usumacinta watershed, Tabasco, Mexico.
    Abstract The Central American River Turtle (Dermatemys mawii) is an endangered species that has been poorly studied. There are no reports on their population status, habitat condition, and the species distribution area is still unknown. This study analyzes the seasonal and spatial variations of their habitat and the presence/absence of D. mawii in three rivers within the Pantanos de Centla Biosphere Reserve (Tabasco, Mexico). For habitat characterization, natural segmentation of rivers was used and three sites per segment were identified, 9 in each rivers (Grijalva and Usumacinta) and 6 in Tabasquillo. Additionally, the evaluation of 11 environmental variables such as water hydrological, physicochemical characteristics and riparian and hydrophytic vegetation were carried out during two different seasons (dry and rainy). The presence/absence of species was assessed with eight fike nets that were set per segment, with a capture effort of 384 hours per trap. The capture per unit effort (CPUE) was used as an indicator of relative abundance. The results indicated spatio-temporal variations in habitat characteristics and the presence of environmental gradients. The principal components analysis (PCA) applied allowed us to determine that the first three components explained 67.8% of the environmental variability. The species presence was confirmed in all rivers, however significant differences exists in their relative abundance: the highest was registered in the Tabasquillo River where the species was present in both seasons and in all segments. Of the 11 environmental variables analyzed, the gradient, shelter and depth were the most indicative of species presence. The obtained results evidenced the importance of riparian vegetation as habitat for Dermatemys. This represents the first approach towards an action plan for a species and its habitat protection within the Pantanos de Centla Biosphere Reserve.

    Title translation Microorganisms effect with probiotic potential in water quality and growth of the shrimp Litopenaeus vannamei (Decapoda: Penaeidae) in intensive culture.
    Abstract The use of probiotics has gained acceptance in aquaculture, particularly in maintaining water quality and enhancing growth in organisms. This study analyzed the effect of the commercial (EM, Japan) natural product composed by (Rhodopseudomonas palustris, Lactobacillus plantarum, Lactobacillus casei and Saccharomyces cerevisiae) added to the water, in order to determine its effect in water quality, sediment and growth of L. vannamei under intensive culture. The evaluation included three treatments with a weekly addition of EM: i) tanks without probiotics (C), ii) tanks with a dose of 4 L/ha (EM1) and iii) tanks with a dose of 10 L/ha (EM2). The treatment C was carried out three times, while treatments EM1 and EM2 were carried out four times. A total of 4 350 shrimps were measured for total length and weight, to calculate total and porcentual weight gain, daily weight gain, specific growth rate (TCE), and food conversion factor (FCA); besides, the survival rate was estimated. The use of probiotics allowed a shorter harvest time in treatments EM1 (90 d) and EM2 (105 d) with relation to the treatment C (120d). Treatments EM1 and EM2 were within the recommended intervals for culture, with respect to treatment C. The use of probiotic bacteria significantly regulated pH (EM1, 8.03 +/- 0.33; EM2, 7.77 +/- 0.22; C, 9.08 +/- 0.35) and reduced nitrate concentration (EM1, 0.64 +/- 0.25 mg/L; EM2, 0.39 +/- 0.26 mg/L; C, 0.71 mg/L). Water pH mostly explained the variance with respect to the treatments. Treatment EM2 presented the greatest removal of organic matter (1.77 +/- 0.45%), whereas the contents of extractable phosphorus increased significantly in treatment EM1 with 21.6 +/- 7.99 mg/kg and in treatment EM2 with 21.6 +/- 8.45 mg/kg with control relation (14.3 +/- 5.47). The shrimp growth was influenced by dissolved oxygen, salinity and pH in the sediment, establishing that salinity was the most important variable in the weight with a negative association. Treatment EM1 recorded an improved TCE (2.69 +/- 0.35%/d) and FCA (1.46 +/- 0.20) with relation to the control treatment (TCE, 1.88 +/- 0.25%/d; FCA, 2.13 +/- 0.48). Survival was significantly greater in treatments containing probiotics with 61 +/- 8.76% and 60 +/- 10.5% for EM1 and EM2, respectively. This study indicated the positive effect obtained with the use of this commercial probiotic, to improve culture conditions and growth parameters in an intensive culture of L. vannamei.
