Coexistence of bacteria with a competition-colonization tradeoff on a dynamic coral hostNARA Subscribed
Many macroscopic organisms enter tightly linked symbioses with microbial communities. Although experimental work has demonstrated the importance of these symbioses, a theoretical understanding of stable, multi-scale coexistence remains underdeveloped. Here, we explored how the competition-colonization tradeoff, a classic coexistence mechanism, operates when bacterial species compete for a dynamic biological host. Specifically,...
Applying harm reduction and implementation principles to urban species conservation managementNARA Subscribed
Private greenspaces adjacent to residential homes represent habitat that could be used to promote the conservation of species and ecosystem health. However, many practices work counteractive to this goal. Even though the research community has documented the negative effects of traditional lawn management and outreach works to promote alternative practices, the suburban and urban lawn continues to grow, with estimates as high...
Shortleaf Pine (Pinus echinata): Management Challenges, Knowledge Gaps, and Opportunities for an Unsung SpeciesNARA Subscribed
Shortleaf pine has the broadest range of the southern pine species, occurring in 22 states and extending north into New Jersey, Pennsylvania, and New York (Staten Island). Shortleaf pine has been understudied compared to loblolly pine and longleaf pine, typically favored for timber production and conservation value, respectively. The extensive range of shortleaf pine contributes to a high degree of variability within and among...
The Damaraland mole-rat ( Fukomys damarensis ) is a cooperatively breeding rodent primarily inhabiting sandy soils of southern Africa. It has the largest distribution of all the species in the genus Fukomys , from northwestern South Africa to Zambia, and from central Namibia across to western Zimbabwe. To the north of the Zambezi River in Zambia, it is replaced by its sister species Micklem’s mole-rat ( Fukomys micklemi ). Des...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
In 2023, more than half of olive harvests ( Olea europaea ) across Spain, Greece, and Türkiye were lost to drought. The same year late freeze destroyed 90% of the peach crop ( Prunus persica ) on the Georgia Piedmont and the apple crop ( Malus domestica ) in central New York, Vermont, and southern Quebec. Climate extremes now rank with the costliest threats to agriculture, but their role in forest recovery from diebacks that a...
Warming winter temperatures are driving range expansion of tropical, cold‐sensitive mangroves into temperate ecosystems. Along the Atlantic coast of North America, the mangrove range limit is particularly sensitive to climate variability and historical data demonstrate that the mangrove‐salt marsh ecotone on this coast has shifted recurrently during recent centuries. However, a comprehensive understanding of how this mangrove‐...
The proportion of individuals that are found to have empty stomachs during a survey of a predator population's diet has been used as an indicator of the average individual's state of energy balance and of the degree to which its feeding rate (i.e., its functional response) is saturated with respect to prey availability. As such, the proportion of empty stomachs provides insights into the effects of prey on predators and vice v...
