Plant responses to changes in temperature can be a key factor predicting the presence and managing invasive plant species while conserving resident native dryland ecosystems. Climate influence germination, establishment, seedling biomass of both species. We tested hypothesis that common widely distributed an ecosystems California respond differently increasing temperatures. To test this, we examined effects variation on per capita three one ( Bromus rubens ) independent 6 week growth trial experiments controlled greenhouse. Higher relative temperatures reduced germination establishment two species, however, was not significantly affected. Specifically, B. Phacelia tanacetifolia reduced. This often outcompete natives, but could potentially shift balance between natives. A warming climate will likely have negative impacts annual here because co-occur with drought. study shows our some resilience relatively significant increases temperature, this favor at least highly noxious

Global change is a multifaceted, unprecedented crisis hitting the life support system of our planet. Among global changes, climate regarded as one most grave threats to biodiversity because its direct impacts on species and ecosystems integrity indirect consequences through synergistic effects with other factors such biological invasions. The challenges presented either reduce or mitigate this derived from require novel synthesis innovation in ecological evolutionary theory. Positive interactions within between trophic levels can play key role resilience communities. Depending tolerance nurse different aspects change, communities be more less resilient those changes. This knowledge has important implications for both natural agroecosystems. Further, fundamental understanding positive also enable effective conservation restoration levers space time. special issue includes studies addressing facilitative response systems change. Key concepts examined included stress, gradients, species, spatial scale, translocation, phylogenetics alongside physiochemicals, variation capacity buffer Alpine, tundra, drylands temperate forests were directly tested, but salient principles relevant all including contribution soil biota call open data collaborative science. Together, corpus work highlighted significance mitigating many biodiversity.

Abstract Interactions between key landscape features in desert ecosystems such as shrubs and other foundation plants can influence avian community assembly. Bird species often use resources microhabitats provided by these for food, perching sites, thermal refuges. Citizen science data, eBird, are broadly accessible be used to examine fine-scale distribution. Coupling this data with factors, native shrubs, conservation practices. eBird offers the opportunity communities across regional ecological gradients. Using we tested hypothesis that shrub density relative differences aridity among sites within region shape structure of bird throughout Central California drylands. Shrub positively influenced observation rates sampled. Decreasing increased positive associations birds shrubs. promise testing predictions at fine spatial scales, further research explore availability reporting regions - particularly drylands subject substantial pressures from climate change globally. Simple drylands, cover, offer a viable path forward potential habitat restoration face changing increasing desertification.
