Edge‐Length Preserving Embeddings of Graphs Between Normed Spaces
ABSTRACT The concept of graph embeddability, initially formalized by Belk and Connelly and later expanded by Sitharam and Willoughby, extends the question of embedding finite metric spaces into a given normed space. A finite simple graph G = ( V , E ) is said to be ( X , Y )‐embeddable if any set of induced edge lengths from an embedding of G into a ...

Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...

Asymmetric Results About Graph Homomorphisms
ABSTRACT Many important results in extremal graph theory can be roughly summarized as “if a triangle‐free graph G$$ G $$ has certain properties, then it has a homomorphism to a triangle‐free graph Γ$$ \Gamma $$ of bounded size.” For example, bounds on homomorphism thresholds give such a statement if G$$ G $$ has sufficiently high minimum degree, and ...

Abstract Ecological communities are complex and exhibit considerable spatial variability, presenting challenges in accurately understanding these systems. A primary obstacle in ecological research is the existence of ‘missing links’ between species: inevitable unobserved interactions that limit our comprehension of ecological networks and their ...

ABSTRACT Aim Investigate patterns of population genetic structure in Southwestern Atlantic marine fishes and evaluate how geographic range, habitat diversity, and evolutionary history shape population connectivity. Location Southwestern Atlantic, including the Caribbean, Brazilian coast, and Patagonian region, between 0°59′ N and 40°16′ S.

Knowledge Spillover Network and Optimal R&D Policy in Oligopoly
ABSTRACT This paper studies optimal R&D policy in a Cournot oligopoly with network‐based knowledge spillovers. Generalizing the standard two‐stage model of Kamien et al. (1992), we characterize the socially optimal policy by decomposing the net externality of private innovation into three channels: the market expansion effect, direct knowledge ...

Global Population Structure and Dynamics of Wheat Powdery Mildew
ABSTRACT The global movement of pests and pathogens can often be traced to human migratory activities that include the movement of agricultural crops. The causal agent of wheat powdery mildew, the ascomycete fungus Blumeria graminis f. sp. tritici (B. graminis f. sp.

Three genotypes – a heat‐resistant maize (Zea mays), a heat‐susceptible maize, and a sorghum (Sorghum bicolor) variety – were grown to the V4 stage in growth chambers under optimal conditions or subjected to heat stress. Plants were grown in soil containing a complex microbial community, or in the same soil with a depleted microbiome.

ABSTRACT Plant viruses are recognized as rapid and effective vectors to deliver CRISPR‐Cas reaction components into plants, a strategy termed virus‐induced gene editing (VIGE). However, VIGE is limited by the host range of the viral vectors. Development of new viral vectors to target a broad range of plant species will potentially enable the delivery ...
