Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns
Oikos, EarlyView.Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

A Bimodal Extension of the Beta-Binomial Distribution with Applications
AxiomsIn this paper, we propose an alternative distribution to model count data exhibiting uni/bimodality. It arises as a weighted version of the beta-binomial distribution, which is defined by a parametric weight function that admits up to two modes for the ...

Biodiversity Data Journal, 2013 Echinorhynchus truttae and the E. bothniensis species complex are common parasites of salmoniform and other fishes in northern Europe. E. bothniensis and its sibling species E. 'bothniensis' are thought to be closely related to the Nearctic E. leidyi Van

Oikos, EarlyView.Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

MortalitySmooth: An R Package for Smoothing Poisson Counts with P-Splines
Journal of Statistical Software, 2012 The MortalitySmooth package provides a framework for smoothing count data in both one- and two-dimensional settings. Although general in its purposes, the package is specifically tailored to demographers, actuaries, epidemiologists, and geneticists who ...

Age ratio in groups of a social ungulate affects epizoochorous dispersal and diaspore exchanges
Oikos, EarlyView.Animal‐mediated seed dispersal is a key process in plant population dynamics, species distribution and ecosystem functioning. As long‐distance dispersal agents, ungulates help to maintain native plant populations facing abiotic changes in their habitat and habitat fragmentation or habitat loss.

Hierarchical Generalized Linear Models: The R Package HGLMMM
Journal of Statistical Software, 2011 The R package HGLMMM has been developed to fit generalized linear models with random effects using the h-likelihood approach. The response variable is allowed to follow a binomial, Poisson, Gaussian or gamma distribution.

Mean and Variance Modeling of Under- and Overdispersed Count Data
Journal of Statistical Software, 2016 This article describes the R package CountsEPPM and its use in determining maximum likelihood estimates of the parameters of extended Poisson process models.

Oikos, EarlyView.Forest restoration success depends crucially on the reinitiation of ecological processes such as seed arrival that drive natural regeneration. We know little about whether, by increasing and diversifying local seed sources to alleviate seed limitation, and attracting animal frugivores to alleviate dispersal limitation, restoration could shift seed ...

Oikos, EarlyView.Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly
