Impact of climate on the migration phenology of the endangered Little Bustard in Spain

open access: yesIbis, EarlyView.
The phenology of animals is closely tied to seasonal climatic patterns so, by altering temperature and precipitation regimes, climate change disrupts the phenological cycles of species. More specifically, the influence of rising temperatures on the phenology of bird migration has been long studied.

Seasonal effects of land cover and intensity of farming practices on α and β diversity of grassland arthropod communities

open access: yesInsect Conservation and Diversity, EarlyView.
Land cover heterogeneity drives grassland arthropod diversity in spring, while local management intensity becomes the primary driver in autumn, revealing strong seasonal shifts in environmental influences. Landscape‐scale farming intensity significantly shapes arthropod community composition through balanced variation, demonstrating its role as an ...

Protection status and environmental gradients shape butterfly assemblages in an East African tropical ecosystem

open access: yesInsect Conservation and Diversity, EarlyView.
Observed butterfly richness was highest in moderately protected areas. During the dry season, vegetation productivity increased butterfly richness while human population density reduced it. Moderately protected areas supported high butterfly abundance and a high proportion of host‐specialist species.

Heuristic approaches for a new variant of the team orienteering problem

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract In this paper, we tackle the team orienteering problem (TOP) with service times, mandatory nodes and incompatibilities arising from two real‐world healthcare applications. We propose two heuristic algorithms: a variable neighbourhood descent algorithm and a matheuristic based on a cut separation approach.

Relationship between the environment and the occurrence of invasive pumpkinseed Lepomis gibbosus in lotic and lentic habitats

open access: yesJournal of Fish Biology, EarlyView.
Abstract The pumpkinseed Lepomis gibbosus is a freshwater fish species native to North America. It has been introduced to Europe, where it is recognized as one of the worst aquatic invaders due to its high adaptability and invasive potential. This study aimed to determine the presence of L. gibbosus in small to medium‐sized water bodies, both lotic and

Climate‐driven niche filtering limits post‐dispersal establishment and genomic introgression in a riverine shrub

open access: yesJournal of Integrative Plant Biology, EarlyView.
Integrated biogeographic analysis and macroecological insights reveal that habitat differences drive genetic differentiation Debregeasia orientalis C. J. Chen, a dominant riparian shrub distributed across multiple biodiversity hotspots, and different lineages vary greatly in adaptability to future climate.

Molecular phylogenetic analysis sheds light on the diversity and evolutionary history of the Neotropical and African Triplophyllum (Tectariaceae)

open access: yesJournal of Systematics and Evolution, EarlyView.
We used a molecular approach to resolve the evolutionary lineages of Neotropical Triplophyllum, uncovering that current species circumscriptions are hindered by high morphological homoplasy in indument characters. Our results support the recognition of three new species and provide a necessary neotypification for T.

California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.
