Multilocus half-tetrad analysis and centromere mapping in citrus: evidence of SDR mechanism for 2n megagametophyte production and partial chiasma interference in mandarin cv 'Fortu... por Cuenca, José, Froelicher, Yann, Aleza, Pablo, Juárez, José, Navarro, Luis, Ollitrault, Patrick

“…All 2n gametes arose from the female genitor. The observed maternal heterozygosity restitution varied between 10 and 82%, depending on the locus, thus SDR appears to be the mechanism underlying 2n gamete production in mandarin cv 'Fortune'. …”

Identification of fruit yield loci controlling the salt tolerance conferred by solanum rootstocks por Estan, M. T., Villalta, Irene, Bolarin, M. C., Carbonell, Emilio A., Asins, María J.

“…The rootstock effect on the fruit yield of a grafted tomato variety was genetically analyzed under salinity using as rootstock two populations of F(9) lines developed from a salt sensitive genotype of Solanum lycopersicum var. cerasiforme, as female parent, and two salt tolerant lines, as male parents, from S. pimpinellifolium, the P population ( 123 lines), and S. cheesmaniae, the C population ( 100 lines). …”

Native and naturalized mealybug parasitoids fail to control the new citrus mealybug pest Delottococcus aberiae por Tena, Alejandro, Garcia-Bellon, Jesus, Urbaneja, Alberto

“…Anagyrus sp. nr. pseudococci and A. angustifrons were able to parasitize both nymph and adult D. aberiae and exhibited a sex ratio biased towards females when they parasitized adults. However, only three specimens were recovered when A. pseudococci was released in three heavily infested citrus orchards. …”

Negative effect of global warming on biological control is mitigated by direct competition between sympatric parasitoids por Cebolla, Ruth, van Baaren, Joan, Tena, Alejandro

“…The R0 of A. melinus decreased approximately 46% with the increase in temperature because the proportion of females was reduced. However, the presence of A. chrysomphali competing in the same patch mitigated the negative effect of the increase in temperature on A. melinus (R0 decreased by only 16%). …”

Jekyll or Hyde? The genome (and more) of Nesidiocoris tenuis, a zoophytophagous predatory bug that is both a biological control agent and a pest por Ferguson, Kim B., Visser, Sander, Daliková, M., Provazniková, I., Urbaneja, Alberto, Pérez-Hedo, Mertixell, Marec, F., Werren, John H., Zwaan, Bas J., Pannebakker, Bart A., Verhulst, Eveline C.

“…Here, we use a linked-read sequencing strategy on a single female N. tenuis. From this, we assembled the 355 Mbp genome and delivered an ab initio, homology-based and evidence-based annotation. …”

Can alteration in host odor blends change the olfactory preferences in Spodoptera littoralis? por Olovsson, Hanna

“…3) Will larvae exposed to altered forms of cotton plant odor behave like larvae exposed to cotton odor or will the detection mechanism of host detection be disturbed? 4) Will adult female Spodoptera littoralis prefer the same plant species as they preferred as larvae? …”

Reindeer calving in enclosures : effect on the mother's activity por Gac Monreal, Ananai

“…To track the movements of the reindeer, 25 reindeer in total were equipped with GPS-collars in both Udtja and Gällivare enclosure and in addition in a freely ranging herd in Udtja. Specifically, female residence time (RT) and step length (distance between adjacent GPS-positions) were calculated as an indication of reindeer movement around calving and overall movement during the period 5 May to 30 May. …”

A descriptive study of the role of maternal behavior in the survival of Markhor (Capra falconeri) kids por Asif, Daniel

“…In a herd of captive Markhors, observations were made to investigate the elements of maternal behavior, interactions of mothers with their kids, visitor’s effect and welfare. Females isolated themselves from other conspecifics before parturition and selected a parturition site in the elevated part of the enclosure. …”

Movement patterns of Eurasian lynx (Lynx lynx) around their kills in southern Sweden por Nystrand, Magnus
