Identification of fossil juniper seeds from Rancho La Brea (California, <span>USA</span>): drought and extirpation in the Late Pleistocene Open
Summary Juniperus spp. are keystone shrubs in western North America and important climatic indicators in paleo‐records. However, a lack of taxonomic resolution among fossil species limits our ability to track past environmental changes. Pl…

Monitoring native, non-native, and restored tropical dry forest with Landsat: A case study from the Hawaiian Islands Open
Tropical dry forests are highly threatened at a global scale. Long-term monitoring of remaining stands is needed to assess forest health, efficacy of management practices, and potential impacts of climate change. Using a multi-seasonal Lan…

Citizen science can complement professional invasive plant surveys and improve estimates of suitable habitat Open
Aim Citizen science is a cost‐effective potential source of invasive species occurrence data. However, data quality issues due to unstructured sampling approaches may discourage the use of these observations by science and conservation pro…

Who, where, when: Observer behavior influences spatial and temporal patterns of iNaturalist participation Open
Understanding the observation process is key to effective use of opportunistic biodiversity data from low-structure citizen science. We investigated how observer characteristics, including activity level (enthusiastic, moderate, or short-t…

A Near Four-Decade Time Series Shows the Hawaiian Islands Have Been Browning Since the 1980s Open
The Hawaiian Islands have been identified as a global biodiversity hotspot. We examine the Normalized Difference Vegetation Index (NDVI) using Climate Data Records products (0.05 × 0.05°) to identify significant differences in NDVI between…

Utility of temporally-biased invasive species distribution models in the detection of Euwallacea sp. nr. fornicatus in California Open
Species distribution models (SDMs) are valuable risk assessment tools in the management of invasive species, for which early detection and containment are critical. Few studies have evaluated the utility of invasive SDMs trained on tempora…

The palm weevil<i>Rhynchophorus vulneratus</i>is eradicated from Laguna Beach Open
In October 2010, Rhynchophorus vulneratus, originally identified as the red palm weevil, R. ferrugineus, was discovered infesting Canary Island date palms in Laguna Beach, California. The red palm weevil has caused extensive mortality of p…

User-Friendly Resource Design: Providing Accessible Ground Squirrel Extension for the Web Open
In terms of internet access, California farmers are some of the most well-connected in the country. According to the USDA, 70% of farms in the U.S. have access to the web as of 2015. In California, 93% of counties exceed that national aver…
