Motivation The database initiated by the Mountain Invasion Research Network (MIREN) is one of the few globally implemented standardized vegetation surveys in mountains. The focus is on collecting plant species occurrences at 5‐year intervals along and adjacent to mountain roads spanning elevational gradients, with the goal of providing critical information about the ongoing spread of non‐native plants and the potential impacts...
Seasonal agricultural vulnerability in semi-arid Morocco: combining remote sensing and farmer knowledge to inform climate adaptationNARA Subscribed
Agricultural systems in semi-arid regions are increasingly exposed to climate variability, yet the drivers of seasonal vulnerability remain insufficiently understood. This study examines whether perceived vulnerability during winter and summer cropping seasons is shaped by distinct mechanisms—climatic exposure during the wet season and adaptive capacity during the dry season. Using Morocco as a representative case for North Af...
Assessing climate and land use changes in Morocco (2001–2023): from a geospatial and farmers’ perspectiveNARA Subscribed
This study examines climate variability and land use dynamics in Morocco from 2001 to 2023 by integrating satellite-derived indicators with farmers’ reported climate risk perceptions. Using MODIS and ERA5-Land datasets within the Google Earth Engine platform, we analyzed trends in cropland extent, normalized difference vegetation index (NDVI), normalized difference water index (NDWI), land surface temperature (LST), air temper...
Pollen, particularly from the Ambrosia genus, plays a pivotal role in triggering allergic rhinoconjunctivitis symptoms. This review delves into the global background of Ambrosia , focusing on its origins, invasive potential, and spread to South America. The ecological niche for Ambrosia species is explored, emphasizing its stability globally but exhibiting unique and dynamic features in South America. Information on Ambrosia p...
The EuroGOOS Coastal working group examines the entire coastal value chain from coastal observations to services for coastal users. The main objective of the working group is to review the status quo, identify gaps and future steps needed to secure and improve the sustainability of the European coastal service provision. Within this framework, our white paper defines a EuroGOOS roadmap for sustained “community coastal downstre...
AMAZONIA CAMTRAP: A data set of mammal, bird, and reptile species recorded with camera traps in the Amazon forestNARA Subscribed
The Amazon forest has the highest biodiversity on Earth. However, information on Amazonian vertebrate diversity is still deficient and scattered across the published, peer‐reviewed, and gray literature and in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales of time and space. In this study, we organized and standardized camera trap records from dif...
Human primary visual cortex shows larger population receptive fields for binocular disparity-defined stimuliNARA Subscribed
The visual perception of 3D depth is underpinned by the brain’s ability to combine signals from the left and right eyes to produce a neural representation of binocular disparity for perception and behaviour. Electrophysiological studies of binocular disparity over the past 2 decades have investigated the computational role of neurons in area V1 for binocular combination, while more recent neuroimaging investigations have focus...
NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the NeotropicsNARA Subscribed
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos,...
