Application of a deep learning image classifier for identification of Amazonian fishes

open access: yesEcology and Evolution, Volume 13, Issue 5, May 2023., 2023
To address the growing prevalence of large ecological datasets combined with a need for rapid species identification tools, we describe a novel application of a computer vision model, which is built to rapidly identify Amazonian fishes from captured image data.

Removing invasive giant reed reshapes desert riparian butterfly and bird communities

open access: yesThe Journal of Wildlife Management, Volume 87, Issue 4, May 2023., 2023
Giant reed is a prevalent invasive plant in desert riparian ecosystems that threatens wildlife habitat. From 2008 to 2018, under a United States–Mexico partnership, prescribed fire and herbicide applications were used to remove giant reed and promote native revegetation along the Rio Grande–Bravo floodplain in west Texas and Mexico.

Floristic diversity, composition and dominance across Amazonian forest types respond differently to latitude

open access: yesJournal of Biogeography, Volume 50, Issue 4, Page 685-698, April 2023., 2023
Abstract Aim The latitudinal biodiversity gradient is considered a first‐order biogeographical pattern for most taxonomic groups. Latitudinal variation in plant diversity is not always consistent, and this could be related to the particular characteristics of different forest types.

Local hydrological conditions influence tree diversity and composition across the Amazon basin

open access: yesEcography, Volume 2022, Issue 11, November 2022., 2022
Tree diversity and composition in Amazonia are known to be strongly determined by the water supplied by precipitation. Nevertheless, within the same climatic regime, water availability is modulated by local topography and soil characteristics (hereafter referred to as local hydrological conditions), varying from saturated and poorly drained to well ...

Effects of forest cover on richness of threatened fish species in Japan

open access: yesConservation Biology, Volume 36, Issue 3, June 2022., 2022
Abstract Estuaries––one of the most vulnerable ecosystems globally––face anthropogenic threats, including biodiversity loss and the collapse of sustainable fisheries. Determining the factors contributing to the maintenance of estuarine biodiversity, especially that of fish, is vital for promoting estuarine conservation and sustainability.

Using interview surveys and multispecies occupancy models to inform vertebrate conservation

open access: yesConservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract Species distribution data are an essential biodiversity variable requiring robust monitoring to inform wildlife conservation. Yet, such data remain inherently sparse because of the logistical challenges of monitoring biodiversity across broad geographic extents.
