Revisiting Darwin's conundrum reveals a twist on the relationship between phylogenetic distance and invasibility.

Study on Phylogenetic Relationship among some of Iranian Wild Almond Species using Sequences of ITS1-5.8S rDNA-ITS2 Region and Chloroplastic trnL

Phylogenetic relations among 12 wild species of almonds, one cultivated almond and one species of peach were investigated by using of ITS1-5.8S rDNA-ITS2 sequences and trnL region of chloroplast DNA. To do this, maximum-parsimony and neighbor joining analysis adopted. Results of ITS data showed that studied species of Prunus only divided in two groups but incapable to separate different section...

Dissecting spatiotemporal patterns of functional diversity through the lens of Darwin's naturalization conundrum

Darwin's naturalization conundrum describes the paradigm that community assembly is regulated by two opposing processes, environmental filtering and competitive interactions, which predict both similarity and distinctiveness of species to be important for establishment. Our goal is to use long-term, large-scale, and high-resolution temporal data to examine diversity patterns over time and asses...

A preliminary study on phylogenetic relationship between five sturgeon species in the Iranian Coastline of the Caspian Sea

The phylogenetic relationship of five sturgeon species in the South Caspian Sea was investigated using mtDNA molecule. Sequence analysis of mtDNA D-loop region of five sturgeon species [Great sturgeon (Huso huso), Russian sturgeon (Acipenser gueldenstaedtii), Persian sturgeon (Acipenser persicus), Ship sturgeon (Acipenser nudiventris), Stellate sturgeon (Acipenser stellatus)] and DNA sequencing...

The Development of a Passive False Twister Mechanism in Handling Low Strength Cotton Slivers on High Draft Spinning Machine

A passive false twist unit (spiral) has been developed to assist with the handling lowstrength slivers on a high speed-spinning machine with a high-speed feed. In the first trial, a falsetwist simulator device was constructed to determine whether the passive false twist unit can be usedon high speed feeding with different can distance from the feeding device. In the second trial, theeffects of ...
