Islanded Islands: Dual Isolation Drive Distinctive and Threatened Floras of Neotropical Maritime Inselbergs

Journal of Vegetation Science, Volume 36, Issue 3, May/June 2025.
ABSTRACT Questions Inselbergs, isolated rock outcrops, support unique plant communities. Maritime inselbergs (MIs) experience transient isolation due to maritime fluctuations, creating harsh survival conditions. This study is the first to investigate the plant communities' patterns on MIs, comparing them with those on continental inselbergs (CIs).

The potential global distribution of the invasive alien species Melinis minutiflora under current and future climates

, 2022
Abstract The invasive exotic plant Melinis minutiflora P.Beauv. is a globally invasive species and impacts the economy, biodiversity, and human well-being. The challenges of biological invasion may be intensified by climate change. The increase in temperatures and concentrations of greenhouse gases may favor the introduction, establishment, and

Differential effects of foraging strategies on carotenoid‐derived plumage color and individual quality in stripe‐tailed yellow finches

Journal of Avian Biology, Volume 2025, Issue 2, March 2025.
Carotenoid‐based plumage color is crucial in avian mate selection, often serving as an indicator of individual quality. To determine whether carotenoid‐derived color can be a sign of individual condition and if there is a relationship between an individual's condition and color production, it is necessary to identify how carotenoids are acquired by ...

Tree species controls over nitrogen and phosphorus cycling in a wet tropical forest

Ecological Monographs, Volume 95, Issue 1, February 2025.
Abstract Wet tropical forests play an important role in the global carbon (C) cycle, but given current rates of land‐use change, nitrogen (N) and phosphorus (P) limitation could reduce productivity in regenerating forests in this biome. Whereas the strong controls of climate and parent material over forest recovery are well known, the influence of ...

Non‐native invasive plants in tropical dry forests: a global review of presence, impacts, and management

Restoration Ecology, Volume 33, Issue 1, January 2025.
Tropical dry forests (TDF) are among the most‐threatened terrestrial ecosystems, experiencing ongoing conversion to agricultural fields, pasture, and human settlements. Human disturbances are often precursors to invasion of ecosystems by non‐native species, but research on invasion patterns in tropical ecosystems is sparse, and there is no ...
