Question
The following paragraph is an abstract from the article tittled: Ecology of the Lesser Siren, Siren intermedia, in an Isolated Eastern Texas Pond
The Lesser Siren (Siren intermedia) is a fully aquatic salamander with functionally limited overland dispersal. Details of the ecology of this species throughout its geographic range and diversity of habitats are limited. In this study, I investigated the ecology of a presumably isolated population of S. intermedia in eastern Texas. The conservative estimated population density was 0.33 sirens/m2 with a standing crop biomass of 9.66 g/m2. Growth rates averaged 0.022 mm/day in total length, slightly slower than other populations. Growth rate was not significantly different between males and females, nor was it correlated with size. The diet of the study population included at least 10 different taxa, of which tadpoles and snails (Order Basommatophora) were the most important prey. Like other populations, activity was highest during late winter and early spring, which coincides with the breeding season. The abundance of siren captures was weakly influenced by water temperature but not correlated with precipitation. Bite marks are hypothesized to be a result of siren courtship behavior. The abundance of males and females captured with fresh bite marks was significantly correlated with the number of gravid females. Because sirens are predatory generalists and represent a significant proportion of biomass in many aquatic environments, it is important to understand siren ecology throughout its geographic range and broad use of habitat types.
The following questions are in regards to the study above:
1.How does this article demonstrate scientific research?
2.What was the question posed by the researcher? (either stated or implied)
3.Did the researcher(s) answer the question? What is the evidence from the article?
4.Is this research a piece of a larger research project? How do you know?
5. Which type of research method and this the projects be categorized under? choose from the following.
Testing a hypothesis, Measuring a function or relationship, Measuring a value, Constructing a model, Observational/exploratory research, Industrial or applied research
Explanation / Answer
1)
The scientific research demonstrated in the article by investigation of ecology of the Lesser Siren, Siren intermedia, in an Isolated Eastern Texas Pond. The research included the study of geographical distribution, population density, growth rate and reproductive behavior of males and females.
2)
The question posed by the researcher was there any significant correlation between geographical distribution, habitat types and reproductive behavior of Siren intermedia with other species and with in same species among males and females?
3)
The researcher answered the question. The evident can be find in the given text : The conservative estimated population density was 0.33 sirens/m2 with a standing crop biomass of 9.66 g/m2. Growth rates averaged 0.022 mm/day in total length, slightly slower than other populations. Growth rate was not significantly different between males and females, nor was it correlated with size. The diet of the study population included at least 10 different taxa, of which tadpoles and snails (Order Basommatophora) were the most important prey. Like other populations, activity was highest during late winter and early spring, which coincides with the breeding season. The abundance of siren captures was weakly influenced by water temperature but not correlated with precipitation. Bite marks are hypothesized to be a result of siren courtship behavior. The abundance of males and females captured with fresh bite marks was significantly correlated with the number of gravid females. Because sirens are predatory generalists and represent a significant proportion of biomass in many aquatic environments, it is important to understand siren ecology throughout its geographic range and broad use of habitat types.
4)
Yes. this research is definitely a part of large reseach project. This can be known from the fact, that the rare or endangered species their geographic distribution, habitat type and reproductive behavior are not studied alone or compared one species but are studied for a group and different species living in a specific environment or ecosystem.
5)
The type of research method used for this study is of observational/exploratory research method.
