Shifts in grasses diversity patterns between two contrasting 40‐year climate periods in tropical dry islands

Ecosphere, Volume 15, Issue 4, April 2024.
Abstract Grasses are one of the most successful and dispersed plant families worldwide and their environmental and economic values are widely acknowledged. They dominate the landscape of Cabo Verde, the southernmost and driest archipelago of Macaronesia, and are relevant natural resources for local populations, but a comprehensive evaluation of their ...

Systematic reduction in seed rain of large‐seeded and endozoochorous species in pastures compared to forests along a tropical elevational gradient

Applied Vegetation Science, Volume 27, Issue 2, April/June 2024.
By analyzing variation in seed rain among old‐growth montane forests and livestock pastures along a 2,000 m elevational gradient in the tropical Andes of southern Ecuador, this study reveals that large seeds and endozoochorous species are less prevalent in seed rain from pastures compared to seed rain from forests at the same elevation.

Roles for leakiness and O2 evolution in explaining lower‐than‐theoretical quantum yields of photosynthesis in the PEP‐CK subtype of C4 plants

New Phytologist, Volume 242, Issue 2, Page 431-443, April 2024.
Summary Theoretically, the PEP‐CK C4 subtype has a higher quantum yield of CO2 assimilation (ΦCO2) than NADP‐ME or NAD‐ME subtypes because ATP required for operating the CO2‐concentrating mechanism is believed to mostly come from the mitochondrial electron transport chain (mETC). However, reported ΦCO2 is not higher in PEP‐CK than in the other subtypes.

Influência das propriedades do solo sobre a abundância das espécies vegetais em campos ferruginosos no sudeste do Brasil [PDF]

, 2008
Ferruginous "campos rupestres" are a particular type of vegetation growing on iron-rich primary soils. We investigated the influence of soil properties on plant species abundance at two sites of ferruginous "campos rupestres" and one site of quartzitic ...

Floristic diversity of patches generated by protected Ficus ‘trees outside forests’ in agricultural landscapes in Madagascar

African Journal of Ecology, Volume 62, Issue 2, February 2024.
Abstract Ficus trees play an important role as key species in both ecological and sociocultural networks in Madagascar. This study focused on species of isolated Ficus growing in agricultural areas adjoining a forest corridor linking the Ranomafana and Andringitra National Parks in east‐central Madagascar, with the aim of understanding the structural ...
