When pollinators are also herbivores ($)

The interaction between wild tobacco (Nicotiana attenuata) and the moth Manduca sexta, which is both a pollinator and a herbivore, is a model for plant/ arthropod interactions and has revealed insights into chemical signals and defenses. Zhou et al. show that a single compound, the sesquiterpene (E)-α-bergamotene,…

Transcriptome analysis illuminates the nature of the intracellular interaction in a vertebrate-algal symbiosis

Chloroplasts are of course the descendants of ancient endosymbiotic cyanobacteria. While there are examples of photosynthetic bacteria or algae living in animal tissues (e.g., anemones and corals), vertebrate endosymbiosis is rare. One exception is the interaction between a salamander Ambystoma maculatum…

Review: Invasion science: A Horizon Scan of emerging challenges and opportunities ($)

Ricciardi et al. describe the conclusions from a “horizon scanning” workshop set up “to identify emerging scientific, technological, and sociopolitical issues that are likely to affect how invasion processes and dynamics are studied and managed within the next 20 years.” Key concerns include…

Update: Stomatal function across temporal and spatial scales: deep-time trends, land-atmosphere coupling and global models

By Peter J Franks, Joseph A Berry, Danica L. Lombardozzi, and Gordon B Bonan The colonization of land by plants and their interaction with biogeochemical and atmospheric processes transformed continental climate and hydrology. Stomata, which evolved to optimize the biological economics of plant carbon…

Review: Insights into grassland ecosystem responses to global environmental change – NutNet ($)

Environmental changes affect the biodiversity (variety of life forms) and productivity (conversion of sunlight energy and carbon into plant biomass) of ecological communities. The collaborative Nutrient Network (NutNet) was created 10 years ago with the goal of synthesizing studies of ecosystem environmental…
