For the 835,580 species in the Class Magnoliopsida (Dicotyledons), we average 4.30 observations each in our database; for the Sucurira-De-Varzea, we have 757 observations. Compared to other species in this Class, this species is extremely common.
A two-sample t-test can be used to determine whether the trend in observations of the Sucurira-De-Varzea is the same as the trend in observations of Magnoliopsida. Is this species just as common, as a proportion of all observations, as it once was? The answer is no, changes in observation rate of this species significantly differ from changes in observation rate of its Class. (t=4.613, p<0.001)
How do observation rates of the Sucurira-De-Varzea differ from those of Magnoliopsida? To answer this, we examined the percentage of observerations for Magnoliopsida that were observations of the Sucurira-De-Varzea each year. We then correlated this percentage with observation year. If observations of the Sucurira-De-Varzea are becoming more common relative to other species of Magnoliopsida, the correlation should be positive, but if it is becoming less common, the correlation should be negative. In fact, the correlation is negative (r=-.23), with a negative slope (m = -.000), suggesting that the Sucurira-De-Varzea may be in decline relative to other species of Magnoliopsida. This correlation is statistically significant. (F = 156.32, p<.05)
The scatter chart to the right shows the percentage of all observations for Magnoliopsida each year that were observations of the Sucurira-De-Varzea.
The Fabaceae are herbs, vines, shrubs, trees, and lianas found in both temperate and tropical areas. They comprise one of the largest families of flowering plants, numbering 630 genera and 18,000 species. The leaves are stipulate, nearly always alternate, and range from bipinnately or palmately compound to simple. The petiolebase is commonly enlarged into a pulvinus that commonly functions in orientation of the leaves (sometimes very responsively, as in the sensitiveplant, Mimosa pudica). The flowers are usually bisexual, actinomorphic to zygomorphic, slightly to strongly perigynous, and commonly in racemes, spikes, or heads. The perianth commonly consists of a calyx and corolla of 5 segments each. The androecium consists of commonly 1- many stamens (most
commonly 10), distinct or variously united, sometimes some of them reduced to staminodes. The pistil is simple, often stipitate, comprising a single style and stigma, and a superior ovary with one locule containing 2-many marginal ovules. The fruit is usually a legume, sometimes a samara, loment, follicle, indehiscentpod, achene, drupe, or berry. The seeds often have a hard coat with hourglass-shaped cells, and sometimes bear a u-shaped line called a pleurogram. [Carr]
