Estudio preliminar de líquenes del orden Peltigerales presentes en el Parque Ecológico y Cultural Rucamanque, Región de La Araucanía, Chile

open access: yesGayana: Botanica, 2021
The Rucamanque Park houses some of the remnants of the Roble-Raulí-Coigüe mixed forest in Central- South Chile. Cortical lichens were monitored in Renoval and in the Original Remnant Forest of Nothofagus obliqua (Mirb.) Oerst.

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years

open access: yesConservation Biology, EarlyView.
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

Assessing Wheat Traits by Spectral Reflectance: Do We Really Need to Focus on Predicted Trait-Values or Directly Identify the Elite Genotypes Group?

open access: yesFrontiers in Plant Science, 2017
Phenotyping, via remote and proximal sensing techniques, of the agronomic and physiological traits associated with yield potential and drought adaptation could contribute to improvements in breeding programs. In the present study, 384 genotypes of wheat (

Scientists’ warning on the global destruction of rock outcrop ecosystems

open access: yesConservation Biology, EarlyView.
Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

The OMZ and nutrient features as a signature of interannual and low-frequency variability in the Peruvian upwelling system [PDF]

open access: yesBiogeosciences, 2017
Over the last decades, the Humboldt Current upwelling ecosystem, particularly the northern component off the coast of Peru, has drawn the interest of the scientific community because of its unique characteristics: it is the upwelling system with the ...

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

open access: yesConservation Biology, EarlyView.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Impact of global change on the distribution of mountain mammals and birds

open access: yesConservation Biology, EarlyView.
Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...

Spatiotemporal Variations in Chemical Composition of Wet Atmospheric Deposition in Mexico City

open access: yesAerosol and Air Quality Research, 2023
A comprehensive analysis of the chemical composition of wet atmospheric deposition was performed on 7048 samples collected between 2003 and 2021 over Mexico City. The descending ion abundance trend was NH4+ > SO42− > NO3− > Ca2+ > Cl− > H+ > Mg2+ > Na+ >

What climate adaptation can learn from evolutionary adaptation

open access: yesConservation Biology, EarlyView.
Abstract Evolutionary and climate adaptation both describe how complex systems respond to environmental change, either via natural selection or deliberate human choices. Although adaptation in both contexts is expected to produce favorable outcomes, it can also result in maladaptation—ineffective, unintended, or harmful outcomes. As an emerging area of

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon

open access: yesConservation Biology, EarlyView.
Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...
