Spatial and Seasonal Biodiversity Variation in a Large Mediterranean Lagoon Using Environmental DNA Metabarcoding Through Sponge Tissue Collection

open access: yesEnvironmental DNA
Ecosystem monitoring is a fundamental tool to avert biodiversity loss, gathering valuable information that can be used to develop conservation policies, evaluate management outcomes, and guide science‐based decision‐making.

The Use of Cognition by Amphibians Confronting Environmental Change: Examples from the Behavioral Ecology of Crawfish Frogs (Rana areolata)

open access: yesAnimals
Amphibian conservation concerns frequently center on the idea of ‘saving’ them, with the underlying assumption they are the passive victims of anthropogenic environmental change.

Populus tremuloides seedling establishment: An underexplored vector for forest type conversion after multiple disturbances [PDF]

open access: yes, 2017
Ecosystem resilience to climate change is contingent on post-disturbance plant regeneration. Sparse gymnosperm regeneration has been documented in subalpine forests following recent wildfires and compounded disturbances, both of which are increasing.

Divergent Responses of Bacterial Communities to Permafrost Degradation and Their Associations With Carbon Across Vertical Profiles

open access: yesAdvanced Science, EarlyView.
Bacterial α‐diversity decreases, but stochasticity and community stability increase across the 15 m‐depth vertical profiles and along the degraded gradient within the active layer. The abundance and interaction of core taxa mainly control community stability in the active and permafrost layers, respectively.

Heuristically Adaptive Diffusion‐Model Evolutionary Strategy

open access: yesAdvanced Science, EarlyView.
Building on the mathematical equivalence between diffusion models and evolutionary algorithms, researchers demonstrate unprecedented control over evolutionary optimization through conditional diffusion. By training diffusion models to associate parameters with specific traits, they can guide evolution toward solutions exhibiting desired behaviors ...

Water Purifying Capacity of Natural Riverine Wetlands in Relation to Their Ecological Quality

open access: yesFrontiers in Environmental Science, 2020
Wetlands are among the crucial nature based solutions for river water purification. The ecological quality of these multi-purposed ecosystems could be disrupted due to overloading of nutrients and other pollutants.

Impacts of local human activities on the Antarctic environment [PDF]

open access: yes, 2008
We review the scientific literature, especially from the past decade, on the impacts of human activities on the Antarctic environment. A range of impacts has been identified at a variety of spatial and temporal scales.

Consensus Formation and Change are Enhanced by Neutrality

open access: yesAdvanced Science, EarlyView.
Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

The biodiversity audit approach challenges regional priorities and identifies a mismatch in conservation [PDF]

open access: yes, 2012
1. Despite a strong uptake of evidence-based approaches, conservation often proceeds from a grossly incomplete understanding of species priorities. To optimize conservation impact within a biogeographical region, quantitative knowledge is needed of the ...

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

open access: yesAdvanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...
