Molecular characterization of bromeliads from northeast Brazil

open access: yesGenetics and Molecular Research, 2014
Bromeliaceae is an important botany family that includes many species with economic value; demand for members of this family is increasing. However, illegal collection frequently occurs, drastically reducing the species populations; thus, it is necessary to collect and store Bromeliaceae genetic material.

Dyckia semperflorenssp. nov. (Bromeliaceae: Pitcairnioideae) from the cold region of Rio Grande do Sul, southern Brazil

open access: yesNordic Journal of Botany, Volume 2026, Issue 1, January 2026.
Dyckia semperflorens (Bromeliaceae: Pitcairnioideae) is described as a new species from the temperate climate region of Rio Grande do Sul state, southern Brazil. The new species belongs to the Dyckia encholirioides complex and is closely related morphologically to Dyckia monticola, which is endemic to the Quiriri mountain range, a high‐altitude region ...

Movement Strategies of Neotropical Nectarivorous Birds: Insights From High‐Andean Hummingbirds and Flowerpiercers

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Nectar is a highly variable, mostly unpredictable resource in tropical mountains. How do nectarivorous birds such as this male Great Sapphirewing cope? Fine‐scaled tracking of hummingbirds and flowerpiercers shows flexibility in daily movement strategies in the high Andes, possibly in response to fluctuating local conditions such as weather and ...

Bromeliad selection by two salamander species in a harsh environment.

open access: yesPLoS ONE, 2014
Bromeliad phytotelmata are frequently used by several Neotropical amphibian taxa, possibly due to their high humidity, microclimatic stability, and role as a refuge from predators.

Multiple Threats Have Overlapping Impacts Across Ecological Levels in Freshwater Ecosystems

open access: yesFreshwater Biology, Volume 71, Issue 1, January 2026.
ABSTRACT Changes driven by climate change, biological invasion, land‐use change, pollution and overexploitation are decreasing the resilience of freshwater ecosystems worldwide. While the impact of these threats is widely recognised, a critical gap remains in systematically quantifying their relative effects across ecological levels, which is essential

Tropical Montane Cloud Forests Have High Resilience to Five Years of Severe Soil Drought

open access: yesGlobal Change Biology, Volume 32, Issue 1, January 2026.
A 5‐year throughfall exclusion experiment in a Peruvian tropical montane cloud forest reduced soil moisture by 69%, leading to lower photosynthetic inputs and autotrophic respiration but maintaining net primary productivity and carbon sink capacity. Trees responded through metabolic downregulation, reduced fruit production, increased wood density, and ...
