Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

Environmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.

LO QUE EINSTEIN LE HUBIERA DICHO A ARISTÓTELES A PROPÓSITO DE LA DINÁMICA Y LA COSMOLOGÍA

Ideas y Valores, 2010
A manera de estudio comparativo, en este artículo se propone un paralelo formal entre la física de Aristóteles y la física de Einstein. La finalidad no es la del rigor histórico. Se trata más bien de un ejercicio de análisis conceptual.

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

Wildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Dinâmica de Perfilhamento do capim-coastcross (Cynodon dactylon (L.) Pers.), submetido a doses de nitrogênio e períodos de rebrotação

Boletim de Indústria Animal, 2008
Este trabalho foi realizado em casa de vegetação objetivando avaliar os efeitos de doses de nitrogênio (N) e do período de rebrotação do capim-coastcross (Cynodon dactylon L. Pers. cv. Coastcross-1) na dinâmica do perfilhamento. Os tratamentos consistiram de doses de N, na forma de uréia, equivalentes a zero; 100; 200 e 300kg ha-1 de N, avaliados em 10

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

From individuals to networks: The role of variation in plant–pollinator communities' responses to global change

Journal of Animal Ecology, EarlyView.
This paper argues that variation among individuals—not just species differences—can shape the sensitivity, robustness and resilience of plant–pollinator communities under global change. By linking individual traits and interaction structure to network dynamics, it provides a new framework and future research directions for predicting community ...
