Counting Cats: Spatially Explicit Population Estimates of Cheetah (Acinonyx jubatus) Using Unstructured Sampling Data.

PLoS ONE, 2016
Many ecological theories and species conservation programmes rely on accurate estimates of population density. Accurate density estimation, especially for species facing rapid declines, requires the application of rigorous field and analytical methods ...

Comparative evaluation of noninvasive DNA sampling and line transect surveys for spring density estimation of black grouse and capercaillie

Wildlife Biology, Volume 2026, Issue 4, July 2026.
Reliable abundance estimates provide essential information in ecology, conservation and management of many wild grouse populations. In this 3‐year study, we comparatively evaluate the suitability of traditional line transect distance sampling of flushed birds versus a spatial capture–recapture survey with noninvasive DNA samples for individual ...

Camera trap distance sampling for density estimation of tiger prey in a Sumatran ecosystem restoration concession

Wildlife Biology, Volume 2026, Issue 4, July 2026.
Estimating prey species densities is critical for implementing effective tiger Panthera tigris recovery strategies. Several statistical models exist for density estimation of unmarked species from camera trap data, all of which rely on the random placement of cameras.

Empirical validation of closed population abundance estimates and spatially explicit density estimates using a censused population of North American red squirrels [PDF]

, 2014
Capture-mark-recapture (CMR) data is widely used to estimate a range of population parameters including abundance and density. Closed population estimators have gained wide acceptance and have become increasingly sophisticated.

Classes características e secantes de curvas racionais normais

, 2023
Estudamos classes características de hipersuperfícies no espaço projetivo complexo, com ênfase nas secantes de curvas racionais normais. Para Seck C ⊂ Pn, a secante de k pontos de uma curva racional normal C ⊂ Pn, calculamos a série de Hilbert e a ...
