“…The nitrate levels were not high (<2 mg L -1 ), except in the summer months (May-June), to cause mortality to zooplankton. For example, the LC 50 for Daphnia magna is about 460 mg L -1 (Camargo et al, 2005). However, phosphate levels were high (annual mean 0.64 mg L -1 ).…”

To understand the population growth potential of different species of rotifers in nature, field collections through seasons are essential. We sampled zooplankton (and measured selected physicochemical variables) from the Madín reservoir, a high altitude eutrophic urban waterbody from Mexico, every month for a year. Qualitative analysis of zooplankton revealed 28 rotifer species and four cladoceran crustaceans plus one unidentified copepod. Cephalodella catellina (1400 ind L -1 ), Horaella thomassoni (550 ind L -1 ), Conochilus dossuarius (380 ind L -1 ) and Filinia longiseta (25 ind L -1 ) had higher peak density than other rotifers. Based on the concentrations of nitrates and phosphates, chlorophyll a levels or different diversity indices (e.g., Carlson, Shannon-Wiener, Pantle and Buck, Ejsmont-Karabin's TSI Rot ), the waterbody is eutrophic to hypertrophic, depending on the season. In this waterbody we observed high densities of Aphanothece sp. which is a toxic picocyanobacterium. During the blooms of Aphanothece, we also recorded higher densities of H. thomassoni and C. catellina. Based on the gut contents we found that both these rotifer species feed on Aphanothece in this waterbody. This study thus suggests the potential growth of Horaella, Cephalodella, Conochilus and Filinia in this eutrophic reservoir containing blooms of Aphanothece.

“…As for low pH, there is a large literature demonstrating nitrate impacts on amphibians and other freshwater organisms (Camargo et al 2005;Mann et al 2009), but further experimental work would be required to investigate the exact nature of the corticosterone response to nitrate. We also saw a link between temperature and stress-induced corticosterone concentrations in the field survey.…”

ABSTRACT Physiological tolerances play a key role in determining species distributions and abundance across a landscape, and understanding these tolerances can therefore be useful in predicting future changes in species distributions that might occur. Vertebrates possess several highly conserved physiological mechanisms for coping with environmental stressors, including the hormonal stress response that involves an endocrine cascade resulting in the increased production of glucocorticoids. We examined the function of this endocrine axis by assessing both baseline and acute stress-induced concentrations of corticosterone in larvae from eight natural breeding populations of Jefferson's salamander Ambystoma jeffersonianum. We surveyed individuals from each pond and also examined a variety of environmental pond parameters. We found that baseline and stress-induced corticosterone concentrations differed significantly among ponds. Population-level baseline corticosterone concentrations were negatively related to pH and positively related to nitrate, and stress-induced concentrations were again negatively related to pH, positively related to nitrate, and positively related to temperature. We followed the field survey with an outdoor mesocosm experiment in which we manipulated pH and again examined baseline and acute stress-induced corticosterone in A. jeffersonianum larvae. As in the field survey, we observed an increase in the baseline corticosterone concentration of individuals exposed to the lowest pH treatment (pH 5-5.8). Examining physiological indices using a combined approach of field surveys and experiments can be a powerful tool for trying to unravel the complexities of environmental impacts on species distributions.

“…A eutrofização artificial gerada pelas atividades humanas tem ocorrido em rios, lagos, estuários e regiões costeiras (RABALAIS, 2002;CENR, 2010;SILVA et al, 2009), tornando-se responsável por profundos danos ambientais em amplas regiões do planeta, a exemplo do Golfo do México e da Baía de Chesapeake, os quais são ecossistemas marcados por fenômenos de hipóxia (ESA, 2002). Como agravante, o nitrogênio, além de atuar como nutriente, mediante suas espécies amônia e nitrato, pode exercer efeitos tóxicos à vida aquática (SILVA & JARDIM, 2006) e à saúde humana (CAMARGO; ALVES; SALAMANCA, 2005). Desta forma, o grau de trofia de um corpo aquático está intimamente associado à DOI: 10.1590/S1413-41522014019000000438 regulação de variáveis que afetam diretamente a proteção da vida aquá-tica, como oxigênio dissolvido e amônia.…”

RESUMOBoth were applied to Anil and Bacanga rivers located on Maranhão Island.Although the general quality of the water indicates human presence, the Anil River stands out by its high trophic level and poor conditions for aquatic life. The results of applying these indexes allow easily assess of the degradation state of the ecosystem. By being connected directly to basic sanitation, these indices are an important management tool for governmental and non-governmental stakeholders.
