Necrotrophic fungal infection affects indolic glucosinolate metabolism in Brassica rapa
Brassica species contains sulfur-containing secondary compounds including glucosinolates which might protect plants from pathogens. In the present...

Micro-habitat features determine oviposition site selection in High Brown and Dark Green Fritillaries
AbstractThe survival of butterfly populations depends on successful oviposition strategies. The limited mobility of early life stages requires...

Variation in foraging patterns as reflected by floral resources used by male vs female bees of selected species at Badlands National Park, SD, USA
Female and male bees forage for different reasons: females provision nests with pollen appropriate for larval development and consume nectar for...

Breviolum and Cladocopium Are Dominant Among Symbiodiniaceae of the Coral Holobiont Madracis decactis
The scleractinian reef building coral Madracis decactis is a cosmopolitan species. Understanding host–symbiont associations is critical for assessing...

Effects of above- and belowground herbivory of specialists and generalists on the growth and defensive chemicals of introduced and native Chinese tallow seedlings
Background and aimsSpatially separated aboveground (AG) and belowground (BG) herbivores can affect each other and alter plant growth and defense,...
-
Preferences of Specialist and Generalist Mammalian Herbivores for Mixtures Versus Individual Plant Secondary Metabolites
Herbivores that forage on chemically defended plants consume complex mixtures of plant secondary metabolites (PSMs). However, the mechanisms by which...
-
Metabolic flexibility allows bacterial habitat generalists to become dominant in a frequently disturbed ecosystem
Ecological theory suggests that habitat disturbance differentially influences distributions of habitat generalist and specialist species. While...

Climate change simulations revealed potentially drastic shifts in insect community structure and crop yields in China’s farmland
Climate change will cause drastic fluctuations in agricultural ecosystems, which in turn may affect global food security. We used ecological niche...

Morphological Variability of the Satyrid Butterflies, Aphantopus hyperantus and Erebia ligea (Lepidoptera, Satyridae) in Allopatric and Allochronous Micropopulations
AbstractThe variability of morphological traits (the shape and size of the forewing and the location, number, and diameter of eyespots in the...
-
Comparative phylogeography of parasitic Laelaps mites contribute new insights into the specialist-generalist variation hypothesis (SGVH)
BackgroundThe specialist-generalist variation hypothesis (SGVH) in parasites suggests that, due to patchiness in habitat (host availability),...

Assessing concrete nest boxes for cavity-nesting bees
Artificial nest boxes for solitary bees and other cavity-nesting Hymenoptera are increasingly used for a variety of purposes, including ecological...
-
Increasing connectivity enhances habitat specialists but simplifies plant–insect food webs
Strong declines of grassland species diversity in small and isolated grassland patches have been observed at local and landscape scales. Here, we...

Niche partitioning between sympatric wild canids: the case of the golden jackal (Canis aureus) and the red fox (Vulpes vulpes) in north-eastern Italy
BackgroundTwo coexisting species with similar ecological requirements avoid or reduce competition by changing the extent of their use of a given...
-
Niche differentiation and evolution of the wood decay machinery in the invasive fungus Serpula lacrymans
Ecological niche breadth and the mechanisms facilitating its evolution are fundamental to understanding adaptation to changing environments,...

Defining the ‘generalist specialist’ niche for Pleistocene Homo sapiens
Definitions of our species as unique within the hominin clade have tended to focus on differences in capacities for symbolism, language, social...
-
Forest decline differentially affects trophic guilds of canopy-dwelling beetles
Key message Decline can affect the structure, resources, and microclimates of the forest canopy, and potentially have cascading effects on...
-
Simplified modelling enhances biocontrol decision making in tomato greenhouses for three important pest species
Generalist and specialist predators are successfully used in biocontrol programs in greenhouse vegetable crops, like tomato. A greenhouse ecosystem...
-
Early-successional saproxylic beetles inhabiting a common host-tree type can be sensitive to the spatiotemporal continuity of their substrate
Intensive forest management has drastically reduced the amount and diversity of dead wood resulting in population decline of saproxylic species....
-
Decline of parasitic and habitat-specialist species drives taxonomic, phylogenetic and functional homogenization of sub-alpine bumblebee communities
The ongoing biodiversity crisis is characterised not only by an elevated extinction rate but also can lead to an increasing similarity of species...

Urban yards as potential conservation space: large, diverse gardens may be valuable resource patches for butterflies
Public and private flower gardens could be valuable for slowing pollinator decline in urbanized areas, as they can potentially provide crucial...
