Mesopredator release moderates trophic control of plant biomass in a Georgia salt marsh.

Predators regulate communities through top-down control in many ecosystems. Because most studies of top-down control last less than a year and focus on only a subset of the community, they may miss predator effects that manifest at longer timescales or across whole food webs. In southeastern US salt marshes, short-term and small-scale experiments indicate that nektonic predators (e.

Academic-practice partnership: Exploring a model for collaborative nursing education in infection prevention and control.

The academic-practice partnership has become increasingly important in nursing education. An academic-practice partnership between a health systems infection prevention and control (IPC) department and its academic affiliate may provide an opportunity to help advance undergraduate nursing students' IPC knowledge and skills and provide IPC staff the opportunity to develop their clinical teaching skills as they teach and mentor students. We convened an exploratory workshop between our private university-based college of nursing and its affiliated health care system IPC department to brainstorm and identify areas for mutual collaboration and gauge interest in formalizing a partnership.

Genetic structure and ecological niche space of lentil's closest wild relative, Lens orientalis (Boiss.) Schmalh.

Crops arose from wild ancestors and to understand their domestication it is essential to compare the cultivated species with their crop wild relatives. These represent an important source of further crop improvement, in particular in relation to climate change. Although there are about 58,000 Lens accessions held in genebanks, only 1% are wild.

Corrigendum: How could the use of crop wild relatives in breeding increase the adaptation of crops to marginal environments?

How Could the Use of Crop Wild Relatives in Breeding Increase the Adaptation of Crops to Marginal Environments?

Alongside the use of fertilizer and chemical control of weeds, pests, and diseases modern breeding has been very successful in generating cultivars that have increased agricultural production several fold in favorable environments. These typically homogeneous cultivars (either homozygous inbreds or hybrids derived from inbred parents) are bred under optimal field conditions and perform well when there is sufficient water and nutrients. However, such optimal conditions are rare globally; indeed, a large proportion of arable land could be considered marginal for agricultural production.

Rebuilding relationships on coral reefs: Coral bleaching knowledge-sharing to aid adaptation planning for reef users: Bleaching emergence on reefs demonstrates the need to consider reef scale and accessibility when preparing for, and responding to, coral bleaching.

Coral bleaching has impacted reefs worldwide and the predictions of near-annual bleaching from over two decades ago have now been realized. While technology currently provides the means to predict large-scale bleaching, predicting reef-scale and within-reef patterns in real-time for all reef users is limited. In 2020, heat stress across the Great Barrier Reef underpinned the region's third bleaching event in 5 years.

Relationships between a common Caribbean corallivorous snail and protected area status, coral cover, and predator abundance.

As coral populations decline across the Caribbean, it is becoming increasingly important to understand the forces that inhibit coral survivorship and recovery. Predation by corallivores, such as the short coral snail Coralliophila abbreviata, are one such threat to coral health and recovery worldwide, but current understanding of the factors controlling corallivore populations, and therefore predation pressure on corals, remains limited. To examine the extent to which bottom-up forces (i.

Positive Interactions in the Coral Macro and Microbiome.

Researchers now recognize the importance of the coral microbiome, but they often overlook other species that live on corals and influence coral-microbe interactions. These 'interstitial associates' should be incorporated into the metaorganism concept for insights into how facilitations between associates, corals, and their microbiomes can be leveraged in ecology and restoration.

Physical Dormancy Release in Seeds Is Related to Environmental Variations.

Seed dormancy and timing of its release is an important developmental transition determining the survival of individuals, populations, and species in variable environments. was used as a model to study physical seed dormancy at the ecological and genetics level. The effect of alternating temperatures, as one of the causes releasing physical seed dormancy, was tested in 178 accessions over three years.

Diversity of Naturalized Hairy Vetch ( Roth) Populations in Central Argentina as a Source of Potential Adaptive Traits for Breeding.

Hairy vetch ( ssp. Roth) is native of Europe and Western Asia and it is the second most cultivated vetch worldwide. Hairy vetch is used as forage species in semiarid environments and as a legume cover crop in sub-humid and humid regions.

A decade of flowering phenology of the keystone saguaro cactus (Carnegiea gigantea).

Premise Of The Study: Phenology is the study of biological life cycle events, such as flowering and migration. Climate patterns can alter these life history events, having ecosystem-wide ramifications. For example, warmer springs are associated with earlier leaf-out for many species, impacting species interactions and growing-season carbon dynamics.

Epibionts on Turbinaria ornata, a secondary foundational macroalga on coral reefs, provide diverse trophic support to fishes.

Worldwide, many coral reef ecosystems have shifted from coral to algal dominance, yet the ecological function of these emergent communities remains relatively unknown. Turbinaria ornata, a macroalga with a rapidly expanding range in the South Pacific, forms dense stands on hard substrate, likely providing ecological services unique from corals. While generally unpalatable, T.

Through the bullet-proof glass: conducting research in prison settings.

A team of academic researchers, clinicians, prison administrators and undergraduate and graduate students came together to conduct an evaluation of a pre-release discharge planning program in a women's prison facility. This paper describes differences between academic and corrections systems, adaptations needed in order to work within the correctional system, pragmatic and ethical issues addressed by our team, and the joys and benefits we experienced doing the project. Team members who had not previously worked in a prison setting found it an extraordinary, transformative learning experience in spite of the challenges.
