Describing posterior distributions of variance components: Problems and the use of null distributions to aid interpretation

Methods in Ecology and Evolution, Volume 14, Issue 10, Page 2557-2574, October 2023., 2023
Abstract Assessing the biological relevance of variance components estimated using Markov chain Monte Carlo (MCMC)‐based mixed‐effects models is not straightforward. Variance estimates are constrained to be greater than zero and their posterior distributions are often asymmetric.

Floristic diversity, composition and dominance across Amazonian forest types respond differently to latitude

Journal of Biogeography, Volume 50, Issue 4, Page 685-698, April 2023., 2023
Abstract Aim The latitudinal biodiversity gradient is considered a first‐order biogeographical pattern for most taxonomic groups. Latitudinal variation in plant diversity is not always consistent, and this could be related to the particular characteristics of different forest types.

A systematic review of animal personality in conservation science

Conservation Biology, Volume 37, Issue 1, February 2023., 2023
Abstract Although animal personality research may have applied uses, this suggestion has yet to be evaluated by assessing empirical studies examining animal personality and conservation. To address this knowledge gap, we performed a systematic review of the peer‐reviewed literature relating to conservation science and animal personality.

Integration of qualitative and quantitative methods for land‐use‐change modeling in a deforestation frontier

Conservation Biology, Volume 36, Issue 6, December 2022., 2022
Abstract Development and implementation of effective protected area management to reduce deforestation depend in part on identifying factors contributing to forest loss and areas at risk of conversion, but standard land‐use‐change modeling may not fully capture contextual factors that are not easily quantified.

Patterns of leaf trait variation underlie ecological differences among sympatric tree species of Damburneya in a tropical rainforest

American Journal of Botany, Volume 109, Issue 9, Page 1394-1409, September 2022., 2022
Abstract Premise Although ecological differentiation driven by altitude and soil is hypothesized to promote coexistence of sympatric tree species of Damburneya (Lauraceae), the mechanistic role of leaf functional variation on ecological differentiation among co‐occurring species remains unexplored.

Systemic Dynamics of Policy Change: Overcoming Some Blind Spots of Punctuated Equilibrium Theory

Policy Studies Journal, Volume 50, Issue 3, Page 527-552, August 2022., 2022
In this article, we analyze dynamics of policy change from the perspective of Punctuated Equilibrium Theory (PET). In particular, we investigate how economic crises impact on patterns of policy change in policy areas that vary in terms of their proximity to economic matters: social, environmental, and morality policy. We make two contributions.

Effects of forest cover on richness of threatened fish species in Japan

Conservation Biology, Volume 36, Issue 3, June 2022., 2022
Abstract Estuaries––one of the most vulnerable ecosystems globally––face anthropogenic threats, including biodiversity loss and the collapse of sustainable fisheries. Determining the factors contributing to the maintenance of estuarine biodiversity, especially that of fish, is vital for promoting estuarine conservation and sustainability.
