Land-use intensification causes multitrophic homogenization of grassland communities
Land-use intensification is a major driver of biodiversity loss. Alongside reductions in local species diversity, biotic homogenization at larger spatial scales is of great concern for conservation.Expand

Host-plant dependent wing phenotypic variation in the neotropical butterfly Heliconius erato
Most phytophagous insects feed on a single plant during development, and this may influence not only performance-linked traits, but also more subtle morphological differences. Insect-plantExpand

An integrated framework to improve the concept of resource specialisation.
TLDR
We build on recent advances in ecophylogenetics and null model analysis to propose a concept of specialisation that comprises affinities among resources as well as their co-occurrence with consumers, and is also linked to ecological and evolutionary processes. Expand

Ecological literacy and beyond: Problem-based learning for future professionals
Ecological science contributes to solving a broad range of environmental problems. However, lack of ecological literacy in practice often limits application of this knowledge. In this paper, weExpand

Host-Plant Specialization Mediates the Influence of Plant Abundance on Host Use by Flower Head-Feeding Insects
Abstract Among-population variation in host use is a common phenomenon in herbivorous insects. The simplest and most trivial explanation for such variation in host use is the among-site variation inExpand

Morphometric Differentiation of Fruit Fly Pest Species of the Anastrepha fraterculus Group (Diptera: Tephritidae)
ABSTRACT Fruit flies (Tephritidae) include pests of quarantine importance, some of which belong to the genus Anastrepha. Some species in this group are difficult to identify. We tested the accuracyExpand

Phylogenetic trophic specialization: a robust comparison of herbivorous guilds
Resource specialization is a key concept in ecology, but it is unexpectedly difficult to parameterize. Differences in resource availability, sampling effort and abundances preclude comparisons ofExpand

Segmentation of Similar Images Using Graph Matching and Community Detection
TLDR
In this paper, we propose a new method to segment sets of similar images using graphmatching and community detection algorithms. Expand

Pollinator availability, mating system and variation in flower morphology in a tropical savanna tree
Widely distributed organisms face different ecological scenarios throughout their range, which can potentially lead to micro-evolutionary differentiation at specific localities. Mating systems ofExpand
