We investigated the extent to which workers reproduce in a dependent-lineage population of the monogynous harvester ant Pogonomyrmex barbatus. Dependent-lineage populations contain two interbreeding, yet genetically distinct mitochondrial lineages, each associated with specific alleles at nuclear loci. Workers develop from matings between lineages, and queens develop from matings within lineage...

A preliminary study of boreal owl, Aegolius funereus richardsoni (Bonaparte), and northern sawwhet owl, Aegolius acadicus acadicus (Gmelin), nests from Nova Scotia, Canada revealed the presence of 14 species of Coleoptera, several of which represent significant extensions of their known ranges. Atheta (Datomicra) celata (Erichson) is newly recorded for North America; Atheta irrita Casey is newl...

Bu makale Faruk Duman’ın “Ve Bir Pars Hüzünle Kaybolur” (2014) ve “Sus Barbatus” (2018) romanlarında karakterlerin doğa ile kurdukları bağı karakterler insan dışı dünya arasındaki maddesel metafiziksel geçişkenlikleri Posthümanizm kuramı altında kendine yer bulan ekofeminist Stacy Alaimo tarafından ortaya konan Bedenler arası geçişkenlik teorisi üzerinden değerlendirip ekoeleştirel açıdan bu ge...

Two outstanding questions in evolutionary biology are whether, and how often, the genetic basis of phenotypic evolution is predictable; and whether genetic change constrains evolutionary reversibility. We address these questions by studying the genetic basis of red flower color in Penstemon barbatus. The production of red flowers often involves the inactivation of one or both of two anthocyanin...

Speciation of two social parasites from their respective hosts is tested using a molecular phylogeny. Alignment of 711 DNA base pairs of mitochondrial cytochrome b gene was used to assess phylogenetic relationships of inquiline species to their hosts and to other members of the genus. We show that the inquiline social parasites of the North American seed harvester ants are monophyletic, descend...

three mesh sizes of multiflament trammel nets (22 mm, 24 mm, and 26 mm) were used in finike bay for red mullet (mullus barbatus l., 1758). the sampling program was arranged during february to may 2012. holt (1963) method was used for selectivity of trammel nets. red mullet was the dominant species in 22 mm mesh size at 52.86%, followed by 25.7% with the 24 mm net and 21.43% with the 26 mm net. ...

Highly productive and vulnerable habitats such as maerl crinoid beds are subject to severe impacts from trawling in Mediterranean Sea. One of the most valuable target species that inhabit these is red mullet, Mullus barbatus, which can achieve there optimum feeding conditions based on infauna, provide some Fatty Acids (FAs) Polyunsaturated (PUFAs) essential shaping life history traits growth re...
