Diversity and conservation status of palms (Arecaceae) in two hotspots of biodiversity in Colombia and Ecuador

PLANTS, PEOPLE, PLANET, Volume 6, Issue 4, Page 885-901, July 2024.
Palms provide vital plant resources and ecosystem services to people across the tropics. To improve conservation guidance, a “health check” of palms in two highly threatened biodiversity hotspots in Colombia and Ecuador was undertaken. Palms are very diverse in these regions, but over one third are threatened with extinction now, especially among ...

Holocene Temperature and Water Stress in the Peruvian Andes: Insights From Lake Carbonate Clumped and Triple Oxygen Isotopes

Paleoceanography and Paleoclimatology, Volume 39, Issue 5, May 2024.
Abstract Global climate during the Holocene was relatively stable compared to the late Pleistocene. However, evidence from lacustrine records in South America suggests that tropical latitudes experienced significant water balance variability during the Holocene, rather than quiescence. For example, a tight coupling between insolation and carbonate δ18O

Exhumed Serpentinites and Their Tectonic Significance in Non‐Collisional Orogens

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 2, February 2024.
Abstract Exhumed serpentinites are fragments of ancient oceanic lithosphere or mantle wedge that record deep fluid‐rock interactions and metasomatic processes. While common in suture zones after closure of ocean basins, in non‐collisional orogens their origin and tectonic significance are not fully understood.

Large‐scale facilitative effects for a single nurse shrub: Impact of the rainfall gradient, plant community and distribution across a geographical barrier

Journal of Ecology, Volume 112, Issue 2, Page 233-245, February 2024.
The effect of a single key shrub that acts as a nurse species is dependent on its distribution range. The co‐inhabiting plant communities and the environment of the distribution range, exemplified in this study through the rainfall gradients, shape the final effect of the shrub.
