Size dimorphism and directional selection in forest millipedes [PDF]

Arthropods, 2019
Sexual Size Dimorphism (SSD) in the diplopod genus Centrobolus has a positive correlation with body size. Length, width and rings are the main components of interspecific variation in diplopod species.

Inter‐ and intraspecific variation in mycotoxin tolerance: A study of four Drosophila species

Ecology and Evolution, 2022
Many mycophagous Drosophila species have adapted to tolerate high concentrations of mycotoxins, an ability not reported in any other eukaryotes. Although an association between mycophagy and mycotoxin tolerance has been established in many Drosophila ...

Haplogenome assembly reveals structural variation in Eucalyptus interspecific hybrids

GigaScience, 2022
Abstract Background De novo phased (haplo)genome assembly using long-read DNA sequencing data has improved the detection and characterization of structural variants (SVs) in plant and animal genomes. Able to span across haplotypes, long reads allow phased, haplogenome assembly in highly outbred

Development of microsatellite markers for identifying Brazilian coffee arabica varieties [PDF]

, 2010
Microsatellite markers, also known as SSRs (Simple Sequence Repeats), have proved to be excellent tools for identifying variety and determining genetic relationships.

Trait-Based Community Assembly along an Elevational Gradient in Subalpine Forests: Quantifying the Roles of Environmental Factors in Inter- and Intraspecific Variability.

PLoS ONE, 2016
Understanding how communities respond to environmental variation is a central goal in ecology. Plant communities respond to environmental gradients via intraspecific and/or interspecific variation in plant functional traits.

Sympatric song variant in mountain chickadees Poecile gambeli does not reduce aggression from black-capped chickadees Poecile atricapillus [PDF]

, 2016
When habitats overlap and species compete for resources, negative interactions frequently occur. Character displacement in the form of behavioural, social or morphological divergences between closely related species can act to reduce negative ...

Intra- and inter-isolate variation of ribosomal and protein-coding genes in Pleurotus: implications for molecular identification and phylogeny on fungal groups

BMC Microbiology, 2017
Background The internal transcribed spacer (ITS), RNA polymerase II second largest subunit (RPB2), and elongation factor 1-alpha (EF1α) are often used in fungal taxonomy and phylogenetic analysis.

Conventional niche overlap measurements are not effective for assessing interspecific competition

Frontiers in Ecology and Evolution, 2023
Interspecific competition is notoriously difficult to detect and quantify, especially in species that are wide-ranging or otherwise difficult to track in the wild.

Sexually size dimorphic brains and song complexity in passerine birds [PDF]

, 2004
Neural correlates of bird song involve the volume of particular song nuclei in the brain that govern song development, production, and perception. Intra- and interspecific variation in the volume of these song nuclei are associated with overall brain ...

Influence of surface water and groundwater on functional traits and trade-off strategies of oasis communities at the end of the Keriya River, China

Frontiers in Plant Science
Plant functional traits reflect the capacity of plants to adapt to their environment and the underlying optimization mechanisms. However, few studies have investigated trade-off strategies for functional traits in desert-wetland ecosystems, the ...
