Large differences in leaf cuticle conductance and its temperature response among 24 tropical tree species from across a rainfall gradient. [PDF]

open access: yesNew Phytol, 2021
Summary More frequent droughts and rising temperatures pose serious threats to tropical forests. When stomata are closed under dry and hot conditions, plants lose water through leaf cuticles, but little is known about cuticle conductance (gmin) of tropical trees, how it varies among species and environments, and how it is affected by temperature.

Trees as net sinks for methane (CH4 ) and nitrous oxide (N2 O) in the lowland tropical rain forest on volcanic Réunion Island. [PDF]

open access: yesNew Phytol, 2021
Summary Trees are known to emit methane (CH4) and nitrous oxide (N2O), with tropical wetland trees being considerable CH4 sources. Little is known about CH4 and especially N2O exchange of trees growing in tropical rain forests under nonflooded conditions. We determined CH4 and N2O exchange of stems of six dominant tree species, cryptogamic stem covers,

Automated identification of diverse Neotropical pollen samples using convolutional neural networks

open access: yesMethods in Ecology and Evolution, Volume 13, Issue 9, Page 2049-2064, September 2022., 2022
Abstract Pollen is used to investigate a diverse range of ecological problems, from identifying plant–pollinator relationships to tracking flowering phenology. Pollen types are identified according to a set of distinctive morphological characters which are understood to capture taxonomic differences and phylogenetic relationships among taxa.

Solar radiation and soil moisture drive tropical forest understory responses to experimental and natural hurricanes

open access: yesEcosphere, Volume 13, Issue 7, July 2022., 2022
Abstract Tropical forest understory regeneration occurs rapidly after disturbance with compositional trajectories that depend on species availability and environmental conditions. To predict future tropical forest regeneration dynamics, we need a deeper understanding of how pulse disturbance events, like hurricanes, interact with environmental ...

Does fine scale spatiotemporal variation in seed rain translate into plant population structure?

open access: yesOikos, Volume 2022, Issue 2, February 2022., 2022
In mast‐seeding species, strong annual variation in seed production is assumed to drive seed fate and ultimately plant recruitment. However, the effects of temporal variation in seed crops on spatial patterns of seed rain and recruitment are poorly understood, in part because of limited data on fine‐scale spatial variation of seed deposition.

New genus and species of Schizomyiina (Diptera, Cecidomyiidae) from Brazil

open access: yesPapéis Avulsos de Zoologia, 2021
A new gall midge genus, Distinctamyia gen. nov., and a new species Distinctamyia matogrossensis sp. nov. (Diptera, Cecidomyiidae) are herein described and illustrated (larvae, pupal exuviae, male and female). The new species induces conical, green, hairy

Substantial Stem Methane Emissions From Rainforest and Cacao Agroforest Partly Negate Soil Uptake in the Congo Basin

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 126, Issue 10, October 2021., 2021
Abstract Most stem CH4 emission investigations were conducted in wetland forests, and it remains unknown whether trees in tropical rainforests on heavily weathered soils are substantial contributors to ecosystem CH4 fluxes. Additionally, Africa remains the continent with the lowest numbers of published field studies on soil greenhouse gas fluxes.
