摘要:Abstract(#br)In brood pollination mutualisms, predation of developing fruit can have large negative repercussions for both plant and pollinator population dynamics. The Sonoran Desert rock fig Ficus petiolaris and its highly-coevolved wasp pollinator are subject to frequent attac...

摘要:Abstract(#br)Fine-scale genetic structure (FSGS) in plants occurs primarily through restricted seed dispersal. Analyses of FSGS have been used retrospectively to infer seed dispersal and other ecological processes. The spring ephemeral Megaleranthis saniculifolia , endemic t...

摘要:Abstract(#br)Population genetics theory predicts that fragmented plant populations do exhibit less genetic diversity, greater genetic divergence, and higher rates of inbreeding than well-preserved, continuous populations. We investigated the effects of habitat fragmentation on le...

摘要:Abstract(#br)Populations of many orchids, especially terrestrial species, have been rapidly decreasing due to mass collection by plant sellers and enthusiasts. Given the presumably negative demographic and genetic consequences, such anthropogenic activity should be taken int...

摘要:Abstract(#br)We investigated allozyme variation in 16 populations of the rare monotypic fern Mankyua chejuense and 11 populations of a closely related, widespread fern Botrychium ternatum . Genetic diversity was extremely low in the critically endangered M. chejuense ( %P s = 10%...

摘要:Abstract(#br)Mutualisms are interactions between two species in which the fitnesses of both symbionts benefit from the relationship. Although examples of mutualism are ubiquitous in nature, the ecology, evolution, and stability of mutualism has rarely been studied in the bro...

摘要:Premise of the study:(#br)Microsatellite primers were developed to investigate population genetic structure in Ficus hirta (Moraceae).(#br)Methods and Results:(#br)Sixteen microsatellite primers were developed and optimized for F. hirta using Illumina paired‐end sequencing o...

摘要:Premise of the study:(#br)Single‐nucleotide polymorphism (SNP) primers were developed for a native North American desert fig, Ficus petiolaris (Moraceae), to provide markers for population genetic studies designed to quantify patterns of gene flow across a complex landscape....

摘要:Abstract(#br)Flower volatile organic compounds (VOCs) emitted from the receptive figs of Ficus (Moraceae) play important roles in maintaining the specificity of pollinator attraction and reproductive isolation between host species. The dominant components of VOCs are terpenoids, ...

摘要:Abstract.(#br) Sequence analysis of the hypervariable internal transcribed spacer (ITS) regions of ribosomal DNA (rDNA) is commonly used to gain insights into plant and animal population structure and phylogeny. We characterized ITS1, ITS2, and the 5.8S coding region of 18 senita...
