Consistent estimation of species abundance from a presence–absence map

Temporally Consistent Depth Map Estimation Using Motion Estimation for 3DTV

In this paper, we propose a new algorithm to estimate temporally consistent depth sequence. Our algorithm first calculates the matching cost using left and right views. In order to enhance the temporal consistency, we modify the matching function by adding the temporal weighting function and we perform the motion estimation technique to refer to the previous depths of moving objects. Experiment...

Estimating Species Abundance from Occurrence.

The effects of acoustic misclassification on cetacean species abundance estimation.

To estimate the density or abundance of a cetacean species using acoustic detection data, it is necessary to correctly identify the species that are detected. Developing an automated species classifier with 100% correct classification rate for any species is likely to stay out of reach. It is therefore necessary to consider the effect of misidentified detections on the number of observed data a...

Comparing models of species abundance Arising from :

E1 Ecologists are struggling to explain how so many tropical tree species can coexist in tropical forests, and several empirical studies have demonstrated that negative density dependence is an important mechanism of treespecies coexistence. Volkov et al. compare a model incorporating negative density dependence with a dispersal-limited neutral model and claim that each predicts six empirical s...

Practical Estimation of Diversity from Abundance Data

Measuring biodiversity requires empirical techniques to effectively estimate it from real data. The well-known underestimation of the number of species applies to low orders of diversity in general. I test nine estimators including three new ones on geometric and lognormal distributions that represent realistic, hyper-diverse communities. The best two estimators allow a good estimation of diver...
