Genetic diversity and spatial genetic structure support the specialist-generalist variation hypothesis in two sympatric woodpecker species
Species are often arranged along a continuum from “specialists” to “generalists”. Specialists typically use fewer resources, occur in more patchily...

Glucosinolate-Myrosinase System and Its Role in Specialist and Generalist Insect Herbivores
One of the best-studied plant chemical defenses is the glucosinolate-myrosinase system found in plants of the family Brassicaceae. There is...

Behavioral pattern of generalist and specialist insect pests to brassicaceous leaf cuticular n-alkanes and free fatty acids
The role of leaf cuticular wax of cabbage, Brassica oleracea L., rapeseed, B. campestris L., and Indian mustard, B. juncea L. in host preference by...

Seasonal variation in AMF colonisation, soil and plant nutrient content in gypsum specialist and generalist species growing in P-poor soils
AimsGypsum soils are P-limited atypical soils that harbour a rich endemic flora. These singular soils are usually found in drylands, where plant...

How do specialist and generalist seed predators affect the highly variable and synchronized seed dispersal of Photinia glabra (Rosaceae), a fleshy-fruited tree?
Fleshy fruits are used by various animals, including legitimate seed dispersers and fruit and seed predators. To clarify the overall effect of these...

It is hot and cold here: the role of thermotolerance in the ability of spiders to colonize tree plantations in the southern Atlantic Forest
Worldwide, with the decline of natural habitats, species with reduced niche breadth (specialists) are at greater risk of extinction as they cannot...

Ant habitat-use guilds response to forest-pasture shifting in the southwestern Amazon
Ant assemblages have been used as bioindicators of biodiversity response to different types of anthropogenic disturbances. However, usual diversity...

Metabolomic profiling reveals shifts in defenses of an invasive plant
Post-introduction evolution of plant defense traits is fundamental to several important theories for plant invasiveness. Research on chemical defense...

Resource spectrum engineering by specialist species can shift the specialist-generalist balance
The mechanisms which influence coexistence of specialist and generalist species in the same environment are a key focus of ecological theory. We use...

Plant–soil feedback effects on conspecific and heterospecific successors of annual and perennial Central European grassland plants are correlated
Plant–soil feedbacks (PSFs), soil-mediated plant effects on conspecific or heterospecific successors, are a major driver of vegetation development....

Variation in defensive traits against herbivores of native and invasive populations of Carpobrotus edulis
The Enemy Release Hypothesis (ERH) predicts that the escape from natural enemies, such as specialist herbivores, may explain the invasiveness of some...

Species Diversity of Three Faunal Communities Along a Successional Cloud Forest Gradient
The relationship between cloud forest regeneration processes and fauna recovery is poorly understood. We assessed the species diversity of...
-
Impact of plant defense level variability on specialist and generalist herbivores
Most organisms are defended against others, and defenses such as secondary metabolites in plants vary across species, individuals, and subindividual...
-
The relationship between preference and switching in flower foraging by bees
It seems self-evident that generalist foragers switch more between resources than specialists but despite diverse ecological and evolutionary...

Effect of mining on the EPT (Ephemeroptera, Plecoptera and Trichoptera) assemblage of Amazonian streams based on their environmental specificity
The way species respond to environmental changes depends on several factors, but mainly on their niche breadth in the face of habitat variability and...

Water limitation and host specificity modulate aphid parasitoid specialization through bottom-up effects
Freshwater resources available for agricultural production are in decline due to global change. Bottom-up forces due to abiotic stress such as water...

Enhancing semi-aquatic species representativeness beyond protected areas: dragonflies in networks of conservation corridors
Complementarity is crucial when prioritizing sites for biodiversity conservation. Networks of conservation corridors (CCs) can contribute to regional...

Develo** Oak Buds Produce Volatile Emissions in Response to Herbivory by Freshly Hatched Caterpillars
Plant responses to damage by insectivorous herbivores are well-documented in mature leaves. The resulting herbivore-induced plant volatiles (HIPVs)...

Fishers (Pekania pennanti) are forest structure specialists when resting and generalists when moving: behavior influences resource selection in a northern Rocky Mountain fisher population
BackgroundStudies of animal habitat selection are important to identify and preserve the resources species depend on, yet often little attention is...

Initial community composition determines the long-term dynamics of a microbial cross-feeding interaction by modulating niche availability
Multi-step substrate consumption pathways can promote microbial biodiversity via cross-feeding. If one cell type preferentially consumes a primary...
