From field to sky: measurement and modeling of transgenic switchgrass pollen dispersal in the atmosphereNARA Subscribed
Accurate tracking and measurement of pollen dispersal in the atmosphere are essential for assessing cross-pollination risks, particularly in the case of genetically engineered (GE) crops. We conducted a series of unique release-recapture field studies with GE switchgrass in Oliver Springs, TN, USA. Two hundred transgenic switchgrass plants ( Panicum virgatum L. “Performer”) were planted at the center of a clear-cut field, with...
Effectiveness of passive trapping and sweep netting for insect pollinator sampling in turf communitiesNARA Subscribed
Pollinator communities in urban and peri-urban turfgrass remain poorly characterized despite the ubiquity of lawns and growing interest in management practices that enhance floral resources within these otherwise resource-limited environments. To address this gap, we evaluated the effectiveness of active (sweep netting at multiple times of day) and passive (molasses traps and blue, white, and yellow pan traps) sampling methods...
Fluvial Export of Carbon and Nutrients from Boreal Catchments Disturbed by Fire and Permafrost ThawNARA Subscribed
Increased frequency and intensity of fire in the boreal forest can degrade permafrost and redistribute large pools of carbon and nitrogen that influence global climate. However, these changes are difficult to observe and predict at regional spatial scales and decadal or longer timescales. As receiving features of landscapes, streams integrate biogeochemical activity within the contributing area and might provide signals of dis...
Coral reefs are threatened by rising sea temperatures that drive widespread bleaching events, leading to coral mortality and loss of diversity. Understanding the mechanisms underlying coral reef resilience to thermal stress is critical for effective conservation. This study investigates the influence of pre-summer temperature patterns upon community-level bleaching prevalence in the austral summers of 2016 and 2017. Pre-summer...
Substantial impacts from the 2024 summer reverse five years of coral cover gains on the Great Barrier ReefNARA Subscribed
Anthropogenic climate change is fuelling repeated marine heatwaves and has triggered the fourth global mass coral bleaching event in 2023–2025, causing widespread coral mortality worldwide. Here, we document the impacts of this event on the Great Barrier Reef (GBR), where heat accumulation peaked in February–March 2024 and caused mass coral bleaching for the seventh time since 1998. We use data from the Australian Institute of...
Using citizen science to overcome data gaps in artisanal fisheries: programme overview and spatiotemporal patternsNARA Subscribed
Artisanal fisheries contribute substantial animal protein to people in many developing countries, yet government resources for fisheries management are limited and typically allocated to larger commercial operations. This leaves artisanal fisheries vulnerable to overfishing and other anthropogenic threats. A co‐management arrangement, whereby government agencies delegate management authority to fishing communities, is a soluti...
