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

First report of cestode infection in the crustacean Artemia persimilis from Southern Chilean Patagonia and its relation with the Neotropical aquatic birds

Editor rating: 8 / 10

Marta Sánchez –– This is the first study of cestode infection in the crustacean Artemia persimilis from Southern Chilean Patagonia. Both, Artemia and their cestode parasites are key ecological groups and while information exists on Eupean populations, there exist very few data in other part of the world. Artemia persimilis is particularly interesting because of its narrow distribution range in south America, compared with other Artemia species.
Site specificity and attachment mode of Symcallio and Calliobothrium species (Cestoda: “Tetraphyllidea”) in smoothhound sharks of the genus Mustelus (Carcharhiniformes: Triakidae)

Editor rating: 9 / 10

Jean-Lou Justine –– Attachment to the host is a major problem faced by any parasite. This innovative paper provides new information about two cestodes of sharks with contrasting morphologies.
Secondary Succession under invasive species (Pteridium aquilinum) conditions in a seasonal dry tropical forest in southeastern Mexico

Editor rating: 8 / 10

Tatiana Tatarinova –– The issue of invasive species has global importance. Additionally, P. aquilinum has a wide distribution and can have detrimental effect on biodiversity, by hindering the establishment of native species.
Hierarchical generalized additive models in ecology: an introduction with mgcv

Editor rating: 8 / 10

Andrew Gray –– A very useful article for researchers looking at using GAMs with clustered or longitudinal data, and one that, despite the title, will be valuable to those working both within and outside ecology.
From climate zone to microhabitat—environmental factors affecting the coastal distribution of tiger beetles (Coleoptera: Cicindelidae) in the south-eastern European biodiversity hotspot

Section Editor rating: 8 / 10

Dezene Huber –– Great analysis of an often-threatened group of insects. More of this type of work is needed across many taxa.
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.
