Stomatal Decoupling From Photosynthesis Under High Temperatures Is Consistent With Stomatal OptimisationNARA Subscribed
Stomatal pores on plant leaves regulate the gain of carbon through photosynthesis and the loss of water through transpiration. Through their responses to environmental conditions, stomata can constrain plant productivity and transpiration fluxes, exerting a strong control on climate feedbacks over land. Although mechanistic modelling of stomata remains a challenge, semi‐empirical and optimisation models have been successfully...
Cross‐Continental Analysis Shows That Disturbance Effects on Reptile Body Condition Do Not Predict Abundance ResponsesNARA Subscribed
Ecological disturbances are discrete events that alter or transform the physical, chemical, or biological characteristics of ecosystems. Disturbance can cause animal populations to decline and, according to the risk‐disturbance hypothesis and population collapse framework, these declines can be predicted by declines in animal body condition. However, no research has empirically examined the general relationship between body co...
The quality of relationships between different actors involved in community-based sustainability initiatives is central to their success. This study examines the role of the qualities of social relationships within 22 different community-based sustainability initiatives each framed round different types of sustainability challenges, from flooding and climate change to community development and youth engagement. Research involv...
Expert range maps of global mammal distributions harmonised to three taxonomic authoritiesNARA Subscribed
Aim Comprehensive, global information on species' occurrences is an essential biodiversity variable and central to a range of applications in ecology, evolution, biogeography and conservation. Expert range maps often represent a species' only available distributional information and play an increasing role in conservation assessments and macroecology. We provide global range maps for the native ranges of all extant mammal spec...
Small‐scale fisheries and local food systems: Transformations, threats and opportunitiesNARA Subscribed
Fish from marine and inland capture fisheries is an important food that contributes significantly to diets and health, but their contribution is somewhat overlooked in food security and poverty‐related policies. Given the current numbers of malnourished people globally, there is a pressing need to consider how to better realize the potential of fish in food systems that can address malnourishment. To do so, we re‐examine the f...
Cp G inclusion in feed reduces sea lice, L epeophtheirus salmonis , numbers following re‐infectionNARA Subscribed
Lepeophtheirus salmonis infections in Atlantic salmon, S almo salar , have been characterized by little to no hyperplastic response and a biphasic immune response that results in chronic inflammation with tissue repair as the infection progresses. We hypothesized that C p G administration with prior lice exposure would enhance epithelial inflammatory mechanisms and boost the A tlantic salmon immune response to L . salmonis , l...
Simulating forest productivity along a neotropical elevational transect: temperature variation and carbon use efficiencyNARA Subscribed
A better understanding of the mechanisms controlling the magnitude and sign of carbon components in tropical forest ecosystems is important for reliable estimation of this important regional component of the global carbon cycle. We used the JULES vegetation model to simulate all components of the carbon balance at six sites along an Andes‐Amazon transect across Peru and Brazil and compared the results to published field measur...
Interannual climatic variation mediates elevated CO 2 and O 3 effects on forest growthNARA Subscribed
We analyzed growth data from model aspen ( Populus tremuloides Michx.) forest ecosystems grown in elevated atmospheric carbon dioxide ([CO 2 ]; 518 μL L −1 ) and ozone concentrations ([O 3 ]; 1.5 × background of 30–40 nL L −1 during daylight hours) for 7 years using free‐air CO 2 enrichment technology to determine how interannual variability in present‐day climate might affect growth responses to either gas. We also tested whe...
