Death and taxes: the case of the depletion of pearl oyster beds in sixteenth-century Venezuela
Article Abstract:
The rapid depletion of the pearl oyster beds off the coast of Cubagua, Venezuela resulted due to overexploitation and ecology of the place, which led to turkey-wing mussel outcompeting the pearl oyster. Research indicates that the exploitation of the pearl oyster beds impacted on the demographics, social, and cultural aspects of the indigenous human populations of the region.

Combining inferences from models of capture efficiency, detectability, and suitable habitat to classify landscapes for conservation of threatened bull trout
Article Abstract:
Simulation andalysis reveals that sampling-only approach is most effective and less prone to error for determining species presence and detection probability as opposed to Bayesian method. Furthermore, lower probability-of-detection thresholds can be specified using both the sampling-only and Bayesian methods leading to lower error and cost-effectiveness.

Unstructured individual variation and demographic stochasticity
Article Abstract:
Research points out that accurate population viability can only be assessed with information on demographic stochasticity in fecundity and estimates of the structure and magnitude of individual variation in demographic traits. The unstructured individual variation in fecundity can affect the demographic variance.
