Volatile Profiles and Resistance to Herbivory in Eastern Hemlock
plant-herbivore interactions host resistance
2015/1/4
Eastern hemlock hosts the hemlock woolly adelgid, an introduced sap-feeding insect that causes rapid deterioration of the host. Like most conifers, eastern hemlock produces a variety of constitutive a...
Floral Herbivory of an Invasive Slug on a Native Weed
Arion lusitanicus taraxacum officinale flower inflorescence seed viability germination
2015/3/11
Effects of floral herbivory (grazing flowers) by slugs on production and quality of seeds of herbaceous plants have been
rarely quantified. We studied consequences of grazing by an invasive slug Ari...
Plant defense, herbivory, and the growth of Cordia alliodora trees and their symbiotic Azteca ant colonies
Allometry Ant–plant mutualism Chamela-Cuixmala Biosphere Reserve
2015/11/13
The effects of herbivory on plant fitness are
integrated over a plant’s lifetime, mediated by ontogenetic
changes in plant defense, tolerance, and herbivore pressure.
In symbiotic ant–plant m...
Plant stages with biotic, indirect defences are more palatable and suffer less herbivory than their undefended counterparts
anti-herbivore defences herbivore preference
2015/11/13
Plants have evolved several anti-herbivory strategies, including direct defences, such as mechanical and chemical
defences, and indirect or biotic defences, such as the recruitment of defending anima...
Sex-Related Differences in Reproductive Allocation, Growth, Defense and Herbivory in Three Dioecious Neotropical Palms
Sex-Related Differences Reproductive Allocation,
2015/11/13
Frequently, in dioecious plants, female plants allocate more resources to reproduction than male plants.
Therefore it is expected that asymmetrical allocation to reproduction may lead to a reproducti...
Insect herbivory declines with forest fragmentation and covaries with plant regeneration mode: evidence from a Mexican tropical rain forest
herbivory declines forest fragmentation
2015/11/13
The consequences of tropical forest fragmentation on herbivory are poorly understood. The limited evidence suggests that
forest fragmentation can have positive, negative or neutral effects on herbivo...
Sediment-mediated suppression of herbivory on coral reefs: Decreasing resilience to rising sea-levels and climate change?
Sediment-mediated suppression of herbivory coral reefs Decreasing resilience rising sea-levels climate change
2014/4/21
We describe a mechanistic basis for maintaining an alternative degraded stable state on coral reefs: sediment-laden algal turfs. Using remote underwater video cameras we quantified rates of herbivory ...
Foliar Antioxidant Enzyme Responses in Cotton after Aphid Herbivory
Aphid Herbivory Cotton Foliar Antioxidant Enzyme Responses
2008/5/23
Cotton aphid (Aphis gossypii G.) populations in the field have fluctuated over the past years, yet it is unknown whether infestation by these insects alters cotton (Gossypium hirsutum L.) physiology. ...

Sediment-mediated suppression herbivory coral reefs Decreasing resilience rising sea levels climate change
2014/4/18
We describe a mechanistic basis for maintaining an alternative degraded stable state on coral reefs: sedimentladen algal turfs. Using remote underwater video cameras we quantified rates of herbivory b...
Amphipod herbivory on the freshwater cyanobacterium Lyngbya wollei: Chemical stimulants and morphological defenses
Amphipod herbivory freshwater cyanobacterium Lyngbya wollei Chemical stimulants morphological defenses
2014/5/4
The freshwater cyanobacterium Lyngbya wollei forms dense mats in lentic systems throughout the southeastern United States and produces paralytic shellfish poisons (PSPs), such as saxitoxins, that coul...
The effects of nutrients and herbivory on competition between a hard coral (Porites cylindrica) and a brown alga (Lobophora variegata)
The effects of nutrients herbivory on competition a hard coral Porites cylindrica a brown alga Lobophora variegata
2014/5/26
Coral reef degradation often involves a phase shift from coral- to macroalgal-dominated reefs. Declining levels of herbivory or increasing supply of nutrients have both been suggested as a cause of in...
Herbivory and irradiance shape periphytic architecture in a Swiss alpine stream
Herbivory irradiance shape periphytic architecture a Swiss alpine stream
2014/6/17
The effects of herbivory and light on epilithic periphyton from Minor Creek (2,200 m above sea level), a Swiss alpine stream, were examined by manipulating light intensity and the densities of two abu...
Herbivory and algal dynamics on the coral reef at Discovery Bay, Jamaica
Herbivory algal dynamics coral reef Discovery Bay Jamaica
2014/6/17
The cover of noncoralline macroalgae increased dramatically on Caribbean reefs during the 1980s and 1990s. A top-down hypothesis, based largely on observations at Discovery Bay, Jamaica, is that this ...
