Evolution of trace gases and particles emitted by a chaparral fire in California [PDF]

, 2012
Biomass burning (BB) is a major global source of trace gases and particles. Accurately representing the production and evolution of these emissions is an important goal for atmospheric chemical transport models.

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 ...

Caracterização florística da vegetação sobre afloramento rochoso na Estação Experimental de Itapeva, SP, e comparação com áreas de campos rupestres e de altitude. Floristic characterization on rocky outcrop in the Itapeva Experimental Station, SP, and comparison with areas of rocky grasslands and high-altitude grasslands. [PDF]

Revista do Instituto Florestal, 2011
A classificação de comunidades vegetais nem sempre é tarefa fácil, principalmente quando se trata de tipos de vegetação pouco estudados. Esse é o caso davegetação sobre afloramento rochoso da Estação Experimental de Itapeva – EEI, situada no sudoeste do

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Improving manual tagging of camera trap videos for wildlife studies: a visual assistance tool applied to the endangered huillin Lontra provocax

Wildlife Biology, EarlyView.
In the last decades, the use of camera traps for wildlife studies has increased significantly due to advancements in technology leading to cost reduction and improved reliability. They facilitate the study of wild animals in their natural environment in a minimally invasive manner, eliminating the need for researchers to remain in the field for long ...

Increasing concentrations of dichloromethane, CH2Cl2, inferred from CARIBIC air samples collected 1998–2012 [PDF]

, 2015
Atmospheric concentrations of dichloromethane, CH2Cl2, a regulated toxic air pollutant and minor contributor to stratospheric ozone depletion, were reported to have peaked around 1990 and to be declining in the early part of the 21st century.
