Microbe-induced resistance involves priming of direct or indirect defenses according to the stage of herbivory. [PDF]
Summary Microbe‐induced resistance (MIR) encompasses a broad range of plant responses that mediate both direct and indirect defenses against herbivores. However, previous studies have addressed MIR in relation to either direct or indirect defenses in isolation, overlooking potential conflicts or synergies that may arise between MIR‐elicited defense ...

Toward a functional understanding of novel fire regimes in tropical forests. [PDF]
Abstract Climate change and land‐use alterations are driving forest fires to unprecedented frequencies and intensities worldwide. Even wet tropical forests—historically rarely subjected to fire—are increasingly experiencing fire disturbances. The impact of wildfires on these forests is likely large, since many of their tree species are not adapted to ...

A low-cost protocol for the optical method of vulnerability curves to calculate <i>P</i> <sub>50</sub>. [PDF]
Abstract Premise The quantification of plant drought resistance, particularly embolism formation, within and across species, is critical for ecosystem management and agriculture. We developed a cost‐effective protocol to measure the water potential at which 50% of hydraulic conductivity (P50) is lost in stems, using affordable and accessible materials ...

Assessing the mechanisms and impacts of shrub invasion in forests: A meta‐analysis
Taken together, these results suggest that restoration efforts should focus on (i) increasing the presence of strong native competitors or functionally diverse native communities, (ii) decreasing sources of invasive shrub propagules while keeping the canopies closed when invasion occurs via high propagule pressure, (iii) avoiding management techniques ...

Today, over 80% of the US and Brazil row crop acreage has plants expressing insecticidal proteins to prevent the damage caused by caterpillars. These plants (crops expressing Bacillus thuringiensis, Bt, toxins) have brought several benefits to farmers, the environment, and society.

Advancing at-risk species recovery planning in an era of rapid ecological change with a transparent, flexible, and expert-engaged approach. [PDF]
Abstract In the face of unprecedented ecological changes, the conservation community needs strategies to recover species at risk of extinction. On the Island of Maui, we collaborated with species experts and managers to assist with climate‐resilient recovery planning for 36 at‐risk native plant species by identifying priority areas for the management ...

Wild herbivores enhance resistance to invasion by exotic cacti in an African savanna
Our experimental and observational findings that wild herbivores confer resistance to invasion by exotic cacti add to evidence that conserving and restoring native herbivore assemblages (particularly megaherbivores) can increase community resistance to plant invasions. Photo credit: Gustavo Lozada (same for potential cover image). Abstract Whether wild

Wet and dry extremes reduce arthropod biomass independently of leaf phenology in the wet tropics
Although two‐thirds of terrestrial vertebrates consume insects and spiders, how changing rainfall regimes will affect arthropods remains poorly understood. Using spatiotemporal variation in tropical montane climate as a natural experiment, we show arthropod biomass maxima at intermediate rainfall as 3 months of both wet and dry extremes reduced ...

We used artificial, plasticine prey to assess temporal (day‐ versus nighttime) and spatial (pubescent versus glabrous host plant) variation in predation in two Panamanian rainforests. We compared attacks on caterpillar‐ and humanoid‐shaped figurines to test whether model prey shape is as important for prey recognition by predators as often assumed.
