The ecology, biogeography, history and future of two globally important weeds : Cardiospermum halicacabum Linn. and C. grandiflorum Sw. [PDF]
Members of the balloon vine genus, Cardiospermum, have been extensively moved around the globe as medicinal and horticultural species, two of which are now widespread invasive species; C. grandiflorum and C. halicacabum. A third species, C. corindum, may

Seasonal variation in the response of a monoecious crop to increased temperature and fertilizers
Climate warming may affect the performance of plants directly through altering vegetative or reproductive traits, and indirectly through modifying interactions with their pollinators. On the other hand, the addition of fertilizers to the soil may increase the quantity and quality of floral rewards, favoring the visitation of pollinators and ...

ABSTRACT Species with extremely small population sizes are critically endangered because of reduced genetic diversity, increased inbreeding and hybridisation threats. Genomic tools significantly advance conservation by revealing genetic insights into endangered species, notably in monitoring frameworks.

Genome Architecture and Speciation in Plants and Animals
ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.

Improved phylogenetic resolution within Siphonophora (Cnidaria) with implications for trait evolution [PDF]
Siphonophores are a diverse group of hydrozoans (Cnidaria) that are found at most depths of the ocean - from the surface, like the familiar Portuguese man of war, to the deep sea.

Summary The evolution of dioecy from hermaphroditism is widely thought to be a response to disruptive selection favoring males and females, driven by advantages of inbreeding avoidance, sexual specialization, or both. It has hitherto been difficult to uncouple the importance of these two hypotheses.

THE MONOECIOUS AND DIOECIOUS CONDITIONS IN SAGITTARIA LATIFOLIA L. (ALISMATACEAE) [PDF]
Field botanists recognize that many populations of plants, largely sexually monoclinic, may contain some individuals with diclinous flowers and that some generally monoecious species may include dioecious individuals in contradiction to descriptions in the taxonomic literature. These deviates, if they comprise a small proportion of the total population,

Abstract Temperate seaweed forests are among the most productive and widespread habitats in coastal waters. However, they are under threat from climate change and other anthropogenic stressors. To effectively conserve and manage these ecosystems under these rising pressures, an understanding of the genetic diversity and structure of habitat‐forming ...

Population Genetics Meets Ecology: A Guide to Individual‐Based Simulations in Continuous Landscapes
This paper aims to be a practical guide to spatial simulation, helping researchers to implement realistic and efficient spatial, individual‐based simulations and avoid common pitfalls. We explore how mating, reproduction, density‐dependent feedback, dispersal, spatial and temporal heterogeneity, and natural selection affect population dynamics and ...
