Ecology and Evolution, Volume 16, Issue 6, June 2026.Large aggregations of wild mammals are declining worldwide, yet opportunistic wildlife videos from non‐scientists can capture rare or ecologically significant events valuable to conservation. Using drone footage of a Cape buffalo megaherd in northern Botswana, we applied automated detection to estimate a total of about 4100 individuals, the largest ...

geoCount: An R Package for the Analysis of Geostatistical Count Data
Journal of Statistical Software, 2015 We describe the R package geoCount for the analysis of geostatistical count data. The package performs Bayesian analysis for the Poisson-lognormal and binomial-logitnormal spatial models, which are subclasses of the class of generalized linear spatial ...

Revisiting the predation paradox for the Wood Thrush, a declining Neotropical migrant
Ecosphere, Volume 17, Issue 6, June 2026.Abstract Despite an increased density of mid‐trophic level predators in urban and suburban areas compared to rural areas, the survival of smaller prey animals, including the eggs and chicks of nesting songbirds, often remains relatively high in these areas.

Robustness of the Poisson log-normal model for bivariate counts
, 2021 Cuando se trata de modelar datos de conteos bivariados, un camino que comunmente se toma es modelar los conteos de forma separada, es decir, asumiendo independencia entre las variables que los representan.

Traffic Distribution of IM Services
ITM Web of Conferences, 2016 With the proposition of new opinion that the distribution of many human activities follows heavy-tailed distribution rather than Poisson distribution, the research on human behaviors has received widely attention.

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 7, Page 1514-1532, June 2026.ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

Importance Sampling for Sums of Lognormal Distributions with Applications to Operational Risk
, 2009 International audienceIn this paper we use Importance Sampling to estimate tail probabilities for a finite sum of lognormal distributions. We use a defensive mixture, and develop a method of choosing the parameters via the EM algorithm; we also consider ...

Catch-per-unit-effort: which estimator is best?
Brazilian Journal of BiologyIn this paper we examine the accuracy and precision of three indices of catch-per-unit-effort (CPUE). We carried out simulations, generating catch data according to six probability distributions (normal, Poisson, lognormal, gamma, delta and negative ...
