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.

A longitudinal study on late-life depression using Hidden Markov Models

openI modelli di Markov nascosti (Hidden Markov Models, HMMs) sono modelli probabilistici molto flessibili, introdotti negli anni ’60 e divenuti popolari nell’analisi delle serie storiche, grazie alla loro capacità di modellare efficacemente dinamiche ...

The Evolution of Male Weapons Is Associated with the Type of Breeding Site in a Clade of Neotropical Frogs

Integrative Zoology, EarlyView.
Male weaponry evolution is often linked to male–male competition, but its relationship with breeding site type remains unclear. Using Leptodactylinae frogs, we found a macroevolutionary correlation between breeding site type and weapon evolution. Also, gains and losses of weapons occurred more frequently in exposed‐breeding sites, an unexpected finding.

Efficient Masked Autoencoder for Birdsong Representation with Applications on Wild Bird Species Classification

Integrative Zoology, EarlyView.
Research on mosquito feeding preferences and the malaria parasites they transmit is essential for understanding the interactions between hosts, vectors, and parasites. In this study, vertebrate hosts were identified in 72 mosquitoes. Most blood meals (58.7%) came from birds, representing 25 species, while 40.0% came from mammals (13 species), and 1.3 ...

Chinese Loans and Africa's Agricultural Investment: A Bayesian Multilevel Modelling Analysis

Global Policy, EarlyView.
ABSTRACT Chinese lending to Africa expanded substantially after 2000, with agriculture often presented as a strategic sector in China–Africa development cooperation. This study examined whether Chinese loans to African agriculture reflected a differentiated financing strategy or formed part of a broader development finance portfolio.

Bayesian inference for Hidden Markov Model

Hidden Markov Models can be considered an extension of mixture models, allowing for dependent observations. In a hierarchical Bayesian framework, we show how Reversible Jump Markov Chain Monte Carlo techniques can be used to estimate the parameters of ...
