Induced responses contribute to rapid adaptation of Spirodela polyrhiza to herbivory by Lymnaea stagnalis

open access: yesCommunications Biology
Herbivory-induced responses in plants are typical examples of phenotypic plasticity, and their evolution is thought to be driven by herbivory. However, direct evidence of the role of induced responses in plant adaptive evolution to herbivores is scarce ...

Effects of landscape context on herbivory and parasitism at different spatial scales [PDF]

open access: yes, 2003
Local community structure and interactions have been shown to depend partly on landscape context. In this paper we tested the hypothesis that the spatial scale experienced by an organism depends on its trophic level.

Selection for persistence of endophyte‐free meadow fescue under intensive grazing versus frequent mowing

open access: yesGrassland Research, EarlyView.
Cattle grazing meadow fescue pasture in remnant oak savanna near Fennimore, Wisconsin. Abstract Background Meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.) is highly adapted to managed rotational grazing systems with sufficient rest periods to promote regrowth and sward longevity.

Landscape composition influences invertebrate herbivory on flowering forbs in semi-natural grasslands

open access: yesBasic and Applied Ecology
Landscape-scale land use is important in driving species communities and interactions. However, despite increasing concerns regarding the ecological consequences of insect declines, our understanding of how the relative proportions of different land ...

Three invasive insects alter Cycas micronesica leaf chemistry and predict changes in biogeochemical cycling

open access: yesCommunicative & Integrative Biology, 2016
Leaf litter chemical traits were measured for Cycas micronesica plants in Guam following leaf herbivory by the scale Aulacaspis yasumatsui, the butterfly Chilades pandava caterpillar, or the leaf miner Erechthias sp. to determine the influence of the non-

Uniform female-biased sex ratios in alpine willows [PDF]

open access: yes, 2012
Premise of the study: The development of biased sex ratios in dioecious plant species has been ascribed to either (1) factors influencing differential adult mortality of male and female plants or (2) factors acting at an early life stage that determine ...

Spatiotemporal Fire Patterns and Post‐fire Forest Change in Peru (2000–2021)

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Fire is increasingly more frequent and severe in many tropical regions, leading to significant forest loss, diminished biodiversity, and reduced Nature's contributions to people (NCPs). In this study, we analyzed the spatiotemporal patterns of fire in Peru and its regions, focusing on: (1) burned area, (2) size, and (3) number of fires, using ...
