Male production in green sea turtles under a feminizing climate: A validated model of sex ratios with temperature‐dependent sex determination

Journal of Animal Ecology, EarlyView.
This study introduces validated methods to predict sex ratios in wild Green sea turtle (Chelonia mydas) nests. It quantifies beach‐scale temperature heterogeneity, incorporates clutch‐level variation in thermal sensitivity and models temperature effects across the thermosensitive period, demonstrating how temporal temperature dynamics and spatial ...

GMM Estimation of Income Distributions from Grouped Data [PDF]

We develop a GMM procedure for estimating income distributions from grouped data with unknown group bounds. The approach enables us to obtain standard errors for the estimated parameters and functions of the parameters, such as inequality and poverty ...

The gamma distribution as an alternative to the lognormal distribution in environmental applications

, 2000
In environmental applications dealing with data from contaminated sites the positively skewed lognormal distribution has been the most commonly used model.

The Value of Controlling Wilding Conifers in New Zealand

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Exotic, invasive conifer tree species, known as ‘wilding conifers’, pose a significant threat to natural ecosystems and are costly to manage, creating a need to identify community preferences in order to inform and balance public investment in their control.

Mainland diversification and recent island lineages in the reduviid genus Tapirocoris: an integrative taxonomic framework with four new species

Insect Science, EarlyView.
Using an integrative taxonomic framework that combines COI DNA barcodes, geometric morphometrics and phylogeography, we revise the assassin bug genus Tapirocoris and recover seven well‐supported species, including four newly described cryptic species.

Intra‐ and Interspecific Effects on Spatio‐Temporal Behavior of Common Commensal Rodent Species

Integrative Zoology, EarlyView.
This study revealed major findings on spatio‐temporal behavior of commensal rodents on a pig farm showing the influence of interspecific dominance on movement behavior and the resulting species‐specific ecological adaptations. Additionally, rodents tend to stay in their home ranges and migration to other stable buildings is only rare.

Bayesian estimation of Persistent Income Inequality by Lognormal Stochastic Volatility Model

, 2013
We estimate inequality including Gini coefficients using a lognormal parametric model for an investigation of persistent inequality. The asymptotic theory of selected order statistics enables us to construct a linear model based on grouped data.

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

Integrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.

Análisis bayesiano para la distribución lognormal generalizada aplicada a modelos de falla con censura Bayesian Analysis for the Generalized Lognormal Distribution Applied to Failure Time Analysis

Revista Colombiana de Estadística, 2011
Existen varias versiones de la distribución lognormal en la literatura estadística y una de ellas está basada en la transformación exponencial de la distribución normal generalizada (NG).
