Functional traits predict changes in floral phenology under climate change in a highly diverse Mediterranean community

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants are shifting their flowering phenology in response to climate change, but trends differ between species and communities. Functional traits can largely explain how different species respond to climate change by shifting their phenology, and can therefore help ...

Informing spatial conservation prioritization with species’ traits

open access: yesConservation Biology, EarlyView.
Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

Chrysoperla externa (Neuroptera: Chrysopidae) as a Potential Biological Control Agent of Raoiella indica (Acari: Tenuipalpidae)

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
First and third instar Chrysoperla externa showed efficient predatory capacity at low R. indica density, but second instar C. externa exhibits a density‐dependent predatory ability. The lacewing C. externa shows promise as a biocontrol agent for R. indica in coconut because it consumed 8362 R. indica females across all its larval instars.

Height and phytotelm size affect the invertebrate communities of epiphytic bromeliads in the Amazon rainforest

open access: yesEcological Entomology, EarlyView.
The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Automated extraction of leaf mass per area from digitized herbarium specimens

open access: yesNew Phytologist, EarlyView.
Summary The digitization of vast herbarium collections has made millions of plant specimen images freely available online, which can now be used to generate phenotypic datasets of unprecedented scope. Here, we assess the potential of computer vision tools to automate the extraction of predicted leaf mass per area (LMApred) from digitized herbarium ...
