Species turnover reveals hidden effects of decreasing nitrogen deposition in mountain hay meadows (2019) PeerJ

Douglas Burns –– Roth et al. present results of an analysis of change in vascular plant community structure at 129 sites in Switzerland over a 15-year period (2003-17) during which atmosp... Read more

Exotic urban trees conserve similar natural enemy communities to native congeners but have fewer pests

Editor rating: 8 / 10

Stephen Livesley –– This is a very well designed and communicated study looking at native and exotic urban tree species and the invertebrate communities they support with regards to their functional role in urban ecological processes
DNA metabarcoding allows non-invasive identification of arthropod prey provisioned to nestling Rufous hummingbirds (Selasphorus rufus)

Section Editor rating: 9 / 10

Dezene Huber –– Really novel use of this emerging technology.
A data science challenge for converting airborne remote sensing data into ecological information

Editor rating: 8 / 10

Alison Boyer –– This paper describes a rigorous comparison of multiple remote-sensing methods that have the potential to advance the application of remote sensing data to ecology.
Remote sensing tree classification with a multilayer perceptron

Editor rating: 8 / 10

Alison Boyer –– Species classification in remote-sensing is an open problem and this paper advances the field by demonstrating the effectiveness of the MLP method in this particular case study. I expect other papers will follow on to test it in other ecosystems.
The nectar report: quantitative review of nectar sugar concentrations offered by bee visited flowers in agricultural and non-agricultural landscapes

Section Editor rating: 8 / 10

Dezene Huber –– Considering the concern (and often reality) of global pollinator declines, it is interesting that the quality of nectar offering by wild and cultivated plants across a geographical range has not been much considered. This paper, as the authors point out, is a good first step in this direction and may help to set the trajectory for further studies.
Pollen metabarcoding reveals broad and species-specific resource use by urban bees

Editor rating: 7 / 10

Stephen Livesley –– I think this is good contribution as it provides a simple demonstration and discussion of how pollen metabarcoding can assist in the study of certain ecological and practical issues.
Termite mound architecture regulates nest temperature and correlates with species identities of symbiotic fungi

Editor rating: 7 / 10

Jorge Curiel Yuste –– Interesting study on the mechanisms that regulate the symbiotic relationship between the termites and the fungi that these termites grow. The authors explore the relationships between the abiotic conditions that fungi require to grow (temperature optimum) and the architecture (ventilation, shape and size) of the termite mounds.
Individual tree crown delineation and tree species classification with hyperspectral and LiDAR data

Editor rating: 7 / 10

Alison Boyer –– The article describes a method for tree crown segmentation, validation with field data, and spectral classification. The analyses were run with R.
Populations and assemblages living on the edge: dung beetles responses to forests-pasture ecotones

Editor rating: 7 / 10

Jorge Curiel Yuste –– A good contribution to understand the strong impact that habitat fragmentation may have over natural communities, their diversity and structure.
Coral disease prevalence estimation and sampling design

Editor rating: 7 / 10

Robert Toonen –– This study shows that the most common field survey methodologies used to estimate coral disease prevalence in the field have low power and confidence. This simulation study provides strong motivation to change the current methodology in the field.

Individual tree segmentation results were promising, with significant correspondence to field trees, but with significant room for ongoing improvement. Michele Dalponte's team (team FEM) had the best results. https://t.co/pvjGk8OW0x https://t.co/rkcSGF0jV8
