Embryo excision in Compositae, with implications for combating biodiversity loss

open access: yesApplications in Plant Sciences, Volume 12, Issue 5, September-October 2024.
Abstract Premise Embryo excision is an effective, under‐described means of promoting germination in the sunflower family and may help to ensure the survival of endangered taxa or lineages with limited seed availability. Methods and Results We describe and illustrate a detailed method of embryo excision used successfully to stimulate germination in a ...

Condición física de los Piqueros de Nazca (Sula granti) durante el período de anidación [PDF]

open access: yes, 2017
Seabirds undergo a notable change in their physical condition (i.e., fluctuations in their weight) as a consequence of the high energetic demand for reproduction both in hatching but particularly during brood rearing.

A methodological workflow for quantitative colouration and colour pattern comparison reveals taxonomic and habitat‐level differences in the polymorphic fire salamander (Salamandra salamandra)

open access: yesJournal of Zoology, Volume 324, Issue 1, Page 34-49, September 2024.
In this study, we use the urodele Salamandra salamandra as a study model to apply an analytical approach for extracting and quantifying colour proportions and patterns variation, using the recently developed R packages patternize and recolorize, to accurately describe and compare colour distribution at both taxonomic and habitat levels.

The specialised buzz pollination syndrome poses a partial barrier to plant invasions

open access: yesJournal of Ecology, Volume 112, Issue 8, Page 1686-1700, August 2024.
We found that plants that exhibit traits consistent with the buzz‐pollination syndrome are underrepresented as invasive species across the globe. Our result suggests that the specialist buzz‐pollination syndrome poses a partial barrier to plant invasions. Our review also highlighted six alternative insect behaviours that can enable invasive plants with

Range‐wide intraspecific variation reflects past adaptation to climate in a gypsophile Mediterranean shrub

open access: yesJournal of Ecology, Volume 112, Issue 7, Page 1533-1549, July 2024.
Despite strong specialization to gypsum soils, past divergent selection related to climatic gradients has driven adaptive population differentiation in Lepidium subulatum. All populations showed high but similar plasticity to drought, indicating that selection did not act against plasticity in harsh environmental conditions.
