Image analysis of Moroccan carob seeds (Ceratonia siliqua L.) revealed substantial intraspecific variations depending on climate and geographic origin

open access: yesEcological Processes, 2022
Background The carob tree (Ceratonia siliqua L.) is one of the most iconic tree species of the Mediterranean region, with valuable economic, ecological and cultural value.

Practice-oriented controversies and borrowed epistemic credibility in current evolutionary biology: phylogeography as a case study [PDF]

open access: yes, 2013
Although there is increasing recognition that theory and practice in science are intimately intertwined, philosophy of science perspectives on scientific controversies have been historically focused on theory rather than practice.

PPNID : a reference database and molecular identification pipeline for plant-parasitic nematodes [PDF]

open access: yes, 2020
Motivation: The phylum Nematoda comprises the most cosmopolitan and abundant metazoans on Earth and plant-parasitic nematodes represent one of the most significant nematode groups, causing severe losses in agriculture.

Applying trait-based models to achieve functional targets for theory-driven ecological restoration [PDF]

open access: yes, 2014
Manipulating community assemblages to achieve functional targets is a key component of restoring degraded ecosystems. The response-and-effect trait framework provides a conceptual foundation for translating restoration goals into functional trait targets,

Food Quality in Producer-Grazer Models: A Generalized Analysis

open access: yes, 2010
Stoichiometric constraints play a role in the dynamics of natural populations, but are not explicitly considered in most mathematical models. Recent theoretical works suggest that these constraints can have a significant impact and should not be ...

Anthropogenic impact on intraspecific ecological-temporal differentiation and structure of populations of pacific salmons

open access: yesИзвестия ТИНРО, 2015
Intraspecific temporal differentiation and population structure should be accounted in fishery, artificial breeding and introduction of anadromous species to provide stability of their ecological and genetic structure and maintain their high abundance ...

Increasing the digital repository of DNA barcoding sequences of sand flies (Psychodidae: Phlebotominae) [PDF]

open access: yes, 2019
Sand f ly identification is complex because it depends on the expertise of the taxonomist. The females show subtle morphological differences and the occurrence of the species complexes are usual in this taxon.

Predictable Patterns Of Disruptive Selection In Stickleback In Postglacial Lakes [PDF]

open access: yes, 2008
Disruptive selection is often assumed to be relatively rare, because it is dynamically unstable and hence should be transient. However, frequency-dependent interactions such as intraspecific competition may stabilize fitness minima and make disruptive ...

DNA barcoding works in practice but not in (neutral) theory. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: DNA barcode differences within animal species are usually much less than differences among species, making it generally straightforward to match unknowns to a reference library.

Comparative values of SSRs, SNPs and InDels for citrus genetic diversity analysis [PDF]

open access: yes, 2015
SSRs have long been considered as almost ideal markers for genetic diversity analysis. With the increasing availability of sequencing data, SNPs and InDels become major classes of codominant markers with genome wide coverage.
