The impact of food enrichment on the behaviour of turtles in captivity : An observational study of McCord’s snake-necked turtle (Chelodina mccordi) and Vietnamese pond turtle (Maur... by Johansson, Erika

“…The automatic feeder produced a decrease in foraging behaviour and increased stereotypic-, aggressive- and same-sex sexual behaviour for multiple individuals. More individuals displayed behavioural changes indicative of good welfare when “The Egg” was used compared to when the automatic feeder was used.…”

Immunokastrering av hangrisar by Öijer, Johanna

“…The aim of this study, including 128 pigs, was to evaluate the effect of a GnRH-vaccine Improvac® on performance and on social and sexual behaviour. Male pigs were assigned to three treatments; surgical castration at four days of age, immunization against GnRH and no castration. …”

Population structure of Puccinia graminis, the cause of stem rust on wheat, barley, and rye in Sweden by Kjellström, Clara

“…The result did also confirm that there is a high genetic diversity within the populations, indicating that sexual recombination can be completed on the aecial host Berberis spp. in Sweden. …”

Odour-mediated behaviour in codling moth, Cydia pomonella : do fermentation odours affect the attraction and oviposition behaviour in codling moth? by Torstensdotter, Lillemor

“…We hypothesized that fermentation odours might induce or influence attraction and oviposition behaviour in C. pomonella moths, and that the behaviour might be sexually dimorphic and modulated by mating state. …”

The way to a man’s heart is through his stomach?: A mixed methods study on causal mechanisms through which cash and in-kind food transfers decreased intimate partner violence by Buller, Anna Maria, Hidrobo, Melissa, Peterman, Amber, Heise, Lori

“…A randomised controlled trial of a cash and in-kind food transfer programme on the northern border of Ecuador showed that transfers reduced physical or sexual violence by 30 %. This mixed methods study aimed to understand the pathways that led to this reduction. …”

High-resolution genotyping and mapping of recombination and gene conversion in the protozoan Theileria parva using whole genome sequencing by Henson, S., Bishop, Richard P., Morzaria, S.P., Spooner, P.R., Pelle, Roger, Poveda, L., Ebeling, M., Kung, E., Certa, U., Daubenberger, C.A., Weihong Qi

“…Like Plasmodium falciparum, the parasite undergoes a transient diploid life-cycle stage in the gut of the arthropod vector, which involves an obligate sexual cycle. As assessed using low-resolution VNTR markers, the crossover (CO) rate in T. parva is relatively high and has been reported to vary across different regions of the genome; non-crossovers (NCOs) and CO-associated gene conversions have not yet been characterised due to the lack of informative markers. …”

Assessment of the genetic diversity of the Tunisian citrus rootstock germplasm by Snoussi-Trifa, Hager, Duval, Marie-France, García-Lor, Andrés, Belfalah, Zina, Froelicher, Yann, Risterucci, Ange-Marie, Perrier, Xavier, Jacquemoud-Collet, Jean-Pierre, Navarro, Luis, Harrabi, Moncef, Ollitrault, Patrick

“…The phenotypic diversity within the varietal groups has resulted from multiple introductions, somatic mutations and rare sexual recombination events. Finally, this diversity study enabled the identification of a core sample of accessions for further physiological and agronomical evaluations. …”

Estudio del modo de herencia del mandarino Moncada tetraploide by Garavello, Miguel, Ortega, Neus, García-Lor, Andrés, Cuenca, José, Aleza, Pablo

“…Con el fin de estudiar el tipo de herencia que presenta este genotipo tetraploide, se realizaron hibridaciones sexuales entre clementina `Clemenules´ diploide y `Moncada´ 4x y entre `Moncada´ 4x y el mandarino `Ananas´ diploide para la obtención de híbridos triploides.La restitución de la heterocigosidad parental (RHP) en las progenies triploides obtenidas se ha analizado con marcadores SSR y SNP posicionados en zonas centroméricas y teloméricas de los nueve grupos de ligamiento del mapa genético de clementina. …”
