1. Insect herbivory and vertebrate grazing impact food limitation and grasshopper populations during a severe outbreak

Abstract:
... Interspecific competition between distantly related herbivores, as well as between large vertebrate herbivores and phytophagous insects, has received little attention. Livestock grazing is the dominant land use in western North American grasslands, where phytophagous insects can be the dominant herbivore. Large scale studies have examined interactions between livestock grazing and grasshoppers, bu ...

Abstract:
... Maternal effects can modify progeny phenotypes to improve their survival under variable conditions, such as changes in food supply. In aphidophagous coccinellids, maternal effects can influence egg size, developmental rate, and final adult body size. Four cohorts of Coleomegilla maculata De Geer larvae were reared from four different points in their mothers' reproductive lives (1st, 12th, 24th, an ...

Subject:
Poecilimon; Tettigoniidae; animals; body size; dimorphism; insects
Abstract:
... One of the most fundamental differences between animals are size differences that are often prominent when comparing species, as well as the sexes within species. One important aim of evolutionary and ecological studies is therefore to understand the pattern of size variation. Bergmann's rule and Rensch's rule are two ideas that describe such general patterns. But whether or not these rules apply ...

Subject:
Adelges tsugae; Fiorinia externa; Tsuga canadensis; females; herbivores; hosts; insects; leaves; neonates; parasitoids; population density; predators; prediction; progeny; shoots; surveys
Abstract:
... Evolutionary theory predicts that ovipositing females that can actively disperse should select hosts that increase offspring performance. However, for organisms that are exclusively passively dispersed, feeding site selection is possible only at the within‐host level. This is particularly important for their offspring, which have strong temporal and spatial dispersal constraints within a host. Suc ...

Carabidae; biological control; body size; invertebrates; pest control; pests; predation; predators
Abstract:
... Determining how multiple predators provide better prey suppression is a key step towards developing conservation biological control strategies. While numerous previous studies have demonstrated that diverse predator assemblages can be more effective in controlling pest populations, others have shown that it is the presence or absence of competitively superior species that is critical to pest biolo ...

6. Examining growth rate and starvation endurance in pit‐building antlions from Mediterranean and desert regions

Myrmeleontidae; climatic factors; starvation; stress response; stress tolerance
Abstract:
... Stressful or stochastic environments may have significant selective effects, leading to increased plasticity or stress resistance. Starvation is a type of stress commonly encountered among organisms inhabiting stochastic environments. Indeed, starvation endurance is an important trait, especially in sit‐and‐wait predators, which experience frequent fluctuations in prey arrivals because of their li ...

7. Factors influencing egg parasitism in sub‐social insects: insights from the treehopper Alchisme grossa (Hemiptera, Auchenorrhyncha, Membracidae)

Abstract:
... Subsocial insects rely on maternal care in order to enhance offspring survival. Subsocial Hoplophorionini treehoppers defend their egg masses from predatory and parasitoid attacks. Egg parasitic wasps are important enemies of the Membracidae. We examined parasitism patterns and female defence mechanisms in the Hoplophorionini treehopper Alchisme grossa (Fairmaire). We examined the effect of aggreg ...

8. Floral resources, body size, and surrounding landscape influence bee community assemblages in oak‐savannah fragments

Abstract:
... Fragmentation of natural habitats due to urban development is predicted to have negative impacts on species diversity. The surrounding landscape (or ‘matrix’) of urban or semi‐natural habitats can sometimes support biodiversity, but the amount of support will depend on species‐specific traits, and on the resources available in the fragment and the matrix. Using data on bees collected from 19 oak‐s ...

Abstract:
... Latex functions as a physical and chemical defence against herbivores that may vary in their responses to latex quantity and chemical composition. In their introduced ranges, many exotic plants experience reduced herbivore regulation, especially from specialist herbivores, which may lead to differences in defences among native and invasive populations. Here, we compared latex produced by seedlings ...

In the present study, the trophic niche of sympatrically occurring parasitoids and the host manipulation they induced were studied. The aim was to identify whether the variation in host response to manipulation is as a resu ...

Abstract:
... In recent decades, several North American bumble bee (Bombus spp.) species have undergone precipitous declines. It is suspected that a parasite or pathogen may be responsible, yet few studies have examined the extent of parasitism and the ecology of host–parasite relationships in U.S. bumble bee populations. A season‐long survey of bumble bees in seven grassland meadows of the northern Shenandoah ...

Abstract:
... Although aggregation in non‐social arthropods is common, its adaptive value is not always clear. Oviposition behaviour of the viburnum leaf beetle (Pyrrhalta viburni) is aggregative, with females preferring to lay eggs on twigs already infested by conspecifics. We previously showed that aggregative oviposition aided in overcoming host plant defences. Here we explore two additional benefits of this ...

Abstract:

The impact of plant invaders on the fitness of native insects has received increasing attention, but it remains unclear how native insects that have a taxonomic conservatism in host–plant use respond to novel hosts. In this study, an experimental approach was taken to this issue by comparing the preference and performance of a native beetle, Cassida piperata Hope, on native hosts Chenopodium album ...

Abstract:
... Myrmecochory, or ant‐mediated seed dispersal, is an important ecological interaction in which ants benefit by gaining nutrition from lipid‐rich elaiosomes attached to seeds and plants benefit from having their seeds dispersed away from parent plants. Most research on the benefits of myrmecochory focuses on primary dispersal, in which ants move seeds to nests, or secondary dispersal, in which ants ...

Abstract:
... Diapause, seasonal physiological dormancy, is the primary life history strategy used by insect species inhabiting temperate climates for seasonal synchronisation. Biotic signals for diapause induction originating from host plants may provide dependable cues for insects expanding from subtropical regions.

Abstract:
... For the first time, diet and isotopic niche overlap among males and two female‐specific colour morphs of a damselfly were quantified to test whether sexual conflict could cause intra‐sexual diet variation. Relative to the green female morph, blue females, similar in coloration to the blue males, may be more likely overlooked by mate‐searching males. If so, blue females should be more likely to for ...
