Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Low-intensity insect herbivory could have large effects on ecosystem productivity through reduced canopy photosynthesis [PDF]

Web Ecology
Our current understanding of the effect of insect herbivory on ecosystem productivity is limited. Previous studies have typically quantified only the amount of leaf area loss or have been conducted during outbreak years when levels of herbivory are much ...

Calcium signaling in plant defense

New Plant Protection, EarlyView.
Calcium signaling acts as a central hub in plant immunity, translating pathogen perception into defense responses. This review highlights the channels, sensors, and signaling networks involved, and discusses how pathogens subvert calcium dynamics, as well as how this knowledge may inspire innovative strategies for engineering durable crop resistance ...

Diet specialization mediates drivers of Cucurbita herbivory in a semi-arid agroecosystem

Current Research in Insect Science
Herbivory is a major fitness pressure for plants and a key driver of crop losses in agroecosystems. Dense monocultures are expected to favor specialist herbivorous insects, particularly those who primarily consume crop species; yet, levels and types of ...

Forbs in Viking lands: the effect of disturbing dominant graminoids on recruitment in tundra grasslands

Oikos, EarlyView.
Grasslands, by definition, are dominated by graminoids. Nevertheless, forbs also make up a substantial part of vascular plant diversity in grasslands and are important resources of mammalian herbivores. However, forb recruitment is constrained by successful dominant graminoids, limiting access to safe sites for germination.

The role of leaf traits and bird-mediated insect predation on patterns of herbivory in a semiarid environment in central Mexico

Botan‪ical Sciences, 2017
Background. In arid environments plants face aridity and herbivory, therefore it has been proposed that both are convergent selective forces. However the drivers of insect herbivory in these ecosystems remain poorly understood. Question.

Global patterns of insect herbivory in gap and understorey environments, and their implications for woody plant carbon storage [PDF]

, 2018
Insect herbivory is thought to favour carbon allocation to storage in juveniles of shade-tolerant trees. This argument assumes that insect herbivory in the understorey is sufficiently intense as to select for storage; however, understoreys might be less ...

Overexploitation can counteract top‐down control and the paradox of enrichment in simple food chains

Oikos, EarlyView.
Because of its high abundance or its high feeding intensity, a consumer can overexploit its resource by consuming it on a shorter timescale than resource regeneration. While this short‐term overexploitation is widespread in nature, its general implications for biotic control patterns and ecosystem stability are not clear.

Seasonal variations in planktonic food web structure affect stability by shifting the distribution of energy fluxes

Oikos, EarlyView.
Seasonality in temperate ecosystems shapes species phenology, influencing interactions and food web structure. Variations in species richness and biomass affect trophic interaction strength, a crucial factor for community stability, which can be assessed through energy fluxes – an essential indicator of ecosystem function.
