Various assisted reproductive techniques have been developed and refined to obtain a large number of offspring from genetically superior animals or obtain offspring from infertile (or subfertile) animals. The embryo transfer is one assisted reproductive technique developed well, aimed at increased productivity of selected females, disease control, importation and exportation of livestock, rapid...

Termites are eusocial insects related to cockroaches that feed on lignocellulose. These insects are key species in ecosystems since they recycle a large amount of nutrients but also are pests, exerting major economic impacts. Knowledge on the molecular pathways underlying reproduction, caste differentiation or lignocellulose digestion would largely benefit from additional transcriptomic data. T...

Non-sticky latex beads and sticky diatoms were used as models to describe mutual coagulation between sticky and non-sticky particles. In mixed suspensions of beads and Thalassiosira nordenskjoeldii, both types of particles coagulated into mixed aggregates at specific rates, from which the interspecific coagulation effic~ency could be calculated. Stickiness between beads and T nordenskjoeldii wa...

budding is a good method of propagation in the persian walnut (juglans regia l.)., however, success of budding is low due to higher root pressure as well as the presence of phenolic compounds in the xylem sap. this study was conducted to compare various budding methods and cut below budding :union: on two and three-year-old persian walnut under field conditions. the experiment was conducted bas...

By grafting operations, interspecific eye chimeras of the cockroaches Gromphadorhina portentosa and Leucophaea maderae were produced. Mechanisms involved the development of both the compound eye and the retina-lamina projection have been studied. Most cell types composing the eyes of these cockroaches are cytologically distinguishable in the chimera; also, retinula axons forming the retina-lami...

Significance to Industry: Magnolia (M. liliiflora ‘Nigra’× M. stellata ‘Rosea’) ‘Ann’ (NA 28344; PI 326570) is a member of the ‘Little Girl’ series of magnolias that have become widely popular. Magnolia ‘Ann’ is characterized by a desirable combination of traits including prolific and remontant flowering and a shrubby form. Due to difficulties in propagating magnolias from cuttings or grafting,...

A partire dall’esperienza di etnografo-marinaio nel progetto Ermenautica, propongo inizialmente una prospettiva riduzione delle dimensioni del mare confrontando le wet ontologies (Steinberg, Peters 2019), riflessioni sulla significazione soggettiva degli oceani (Helmreich 2010, 2019) e il discorso sui regimi planetarietà in campo umanistico (Chakrabarty, Latour 2020). Successivamente, concentra...

PREMISE OF THE STUDY Interspecific reproductive barriers (IRBs) often prevent hybridization between closely related species in sympatry. In the tomato clade (Solanum section Lycopersicon), interspecific interactions between natural sympatric populations have not been evaluated previously. In this study, we assessed IRBs between members of the tomato clade from nine sympatric sites in Peru. ME...
