Alternative seed trait strategies are linked to a trade‐off between spatial and temporal dispersal

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Seed dispersal allows plants to seek favourable conditions or spread the risk of unfavourable conditions through space and time. While theory predicts a trade‐off between spatial and temporal dispersal, empirical tests have been stymied by the difficulty of measuring ...

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.

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.

Discovering the unseen: A performance comparison of taxonomic classification methods for unknown DNA barcodes

Methods in Ecology and Evolution, EarlyView.
Abstract DNA barcoding and metabarcoding have emerged as cost‐efficient, standardized methods for characterizing local biodiversity. Based on the sequencing of a small targeted gene fragment, it is theoretically possible to identify a wide diversity of taxa by comparing them with reference sequence databases.

Spatial signatures of group cohesion

Methods in Ecology and Evolution, EarlyView.
Abstract Wildlife populations are undergoing unprecedented changes to their spatial distributions as a result of human activities. Innovative approaches are needed to document these changes, especially in cases where sampling is sparse. Here, we contribute to the tools available in spatial ecology by developing novel metrics based on the coefficient of

Behavioural state identification from ultra‐high‐frequency movement data

Methods in Ecology and Evolution, EarlyView.
Abstract The hidden Markov model (HMM) is a central framework for identifying behavioural state changes from animal movement data. In this context, movement is typically represented as a sequence of observed metrics, such as step length and turning angle distributions, generated by an unobserved behavioural state process.

Weekend Overload: Day‐to‐Day Fluctuations of Outdoor Recreation Affect Wild Mammals' Space‐Use in a Popular Forest Reserve Near Florence, Italy

Animal Conservation, EarlyView.
In an urban‐adjacent forested area, we investigated the spatial and temporal distribution of the wild mammal community in relation to day‐to‐day fluctuations of human presence occurring between working days and weekends. We deployed 52 camera‐traps systematically within an EU Natura 2000 area located within the metropolitan area of Florence, central ...

The natural history of periodontal disease—Part 2: In populations with access to dental care: The Studies of Health in Pomerania (SHIP)

Periodontology 2000, EarlyView., 2023
Abstract In this descriptive analysis of the 21‐year follow‐up data from the SHIP‐START cohort and the 7‐year follow‐up data from the SHIP‐TREND cohort, we report the progression of clinical attachment levels (CAL), age effects on CAL change, and a detailed description of CAL progression and remission. At baseline, 4307 and 4420 persons participated in
