Existing treetop detection ... Full text Cite

Masting is uncommon in trees that depend on mutualist dispersers in the context of global climate and fertility gradients.

Journal Article Nature plants · July 2023 The benefits of masting (volatile, quasi-synchronous seed production at lagged intervals) include satiation of seed predators, but these benefits come with a cost to mutualist pollen and seed dispersers. If the evolution of masting represents a balance bet ... Full text Cite

Habitat–trait interactions that control response to climate change: North American ground beetles (Carabidae)

Journal Article Global Ecology and Biogeography · June 1, 2023 Aim: As one of the most diverse and economically important families on Earth, ground beetles (Carabidae) are viewed as a key barometer of climate change. Recent meta-analyses provide equivocal evidence on abundance changes of terrestrial insects. Generaliz ... Full text Cite

Linking seed size and number to trait syndromes in trees

Journal Article Global Ecology and Biogeography · May 1, 2023 Aim: Our understanding of the mechanisms that maintain forest diversity under changing climate can benefit from knowledge about traits that are closely linked to fitness. We tested whether the link between traits and seed number and seed size is consistent ... Full text Cite

Spatiotemporal evolution of urbanization and its implications to urban planning of the megacity, Shanghai, China
