Eukaryotic Communities in Bromeliad Phytotelmata: How Do They Respond to Altitudinal Differences?

Diversity, 2020
Bromeliad phytotelmata are habitats for different organisms and models for ecological studies. Although poorly known, these environments are widely distributed in tropical ecosystems, harboring cosmopolitan and endemic species.

Effects of warming on the structure of aquatic communities in tropical bromeliad microecosystems. [PDF]

Ecol Evol, 2023
Freshwaters are among the most vulnerable ecosystems to climate warming, with projected temperature increases over the coming decades leading to significant losses of aquatic biodiversity. Experimental studies that directly warm entire natural ecosystems

Colonization and extinction mediate environmental effects on the phylogenetic diversity of invertebrate communities. [PDF]

Ecology
Abstract Phylogeny offers a powerful framework for understanding mechanisms driving community assembly. Yet, most empirical studies in community phylogenetics rely on observational approaches. In this study, we explore how two important drivers of community assembly—habitat size and predator presence—shape species richness and phylogenetic relatedness ...

In Vitro Germination and Propagation of Dyckia brevifolia, an Ornamental and Endangered Bromeliad

Horticulturae, 2022
Dyckia brevifolia is an endangered plant used for ornamental purposes. As no references to the in vitro propagation of the species exist, the present study aims at investigating the possibility of an efficient micropropagation protocol.

Comparison of eDNA and visual surveys for rare and cryptic bromeliad-dwelling frogs

Herpetological Journal, 2021
Surveys of rare or cryptic species may miss individuals or populations that are actually present. Despite the increasing use of environmental DNA (eDNA) analysis to survey species in ponds, rivers, and lakes, very few studies have attempted to use eDNA ...

Species Distribution Modeling Reveals Future Climate Refugia and Important Areas for Rocky Plants in Brazil's Iron Quadrangle. [PDF]

Ecol Evol
Climate change is projected to sharply reduce suitable habitats for eight endemic rupestrian plant species in Brazil's Iron Quadrangle. Ensemble niche models reveal species‐specific vulnerabilities and highlight climatic refugia and corridors that may support persistence.

Extreme rainfall events alter the trophic structure in bromeliad tanks across the Neotropics

Nature Communications, 2020
Changes in global and regional precipitation regimes are among the most pervasive components of climate change. Intensification of rainfall cycles, ranging from frequent downpours to severe droughts, could cause widespread, but largely unknown ...

Phytochemical analysis and biological activities of in vitro cultured Nidularium procerum, a bromeliad vulnerable to extinction

Scientific Reports, 2020
This study reports the first phytochemical and biological characterization in treatment of adrenocortical carcinoma cells (H295R) of extracts from Nidularium procerum, an endemic bromeliad of Atlantic Forest vulnerable to extinction.

Influence of environmental and morphological parameters on the microfauna community present in phytotelmata of a bromeliad in a fragment of Atlantic Forest, southern Brazil

, 2021
Bromeliads are important epiphytes due to their abundance in the Neotropical region and morphological complexity. Their compact and imbricated leaf bases form water storage cisterns that promote important resources for colonization by several prokaryotic

Influence of light, dark, temperature, and drought on metabolite and ion composition in nectar and nectaries of an epiphytic bromeliad species (Aechmea fasciata).

Plant biology, 2020
Research into the influence of stress factors such as drought, different temperatures, and or varied light conditions on plants due to climate changes is becoming increasingly important.
