A Rickettsia Genome Overrun by Mobile Genetic Elements Provides Insight into the Acquisition of Genes Characteristic of an Obligate Intracellular Lifestyle by Gillespie, Joseph J., Joardar, Vinita S., Williams, Kelly P., Driscoll, Timothy, Hostetler, Jessica B., Nordberg, Eric, Shukla, Maulik, Walenz, Brian P., Hill, Catherine A., Nene, Vishvanath M., Azad, Abdu F., Sobral, Bruno W., Caler, Elisabet

“…We present the draft genome for the Rickettsia endosymbiont of Ixodes scapularis (REIS), a symbiont of the deer tick vector of Lyme disease in North America. Among Rickettsia species ( Alphaproteobacteria: Rickettsiales ), REIS has the largest genome sequenced to date (>2 Mb) and contains 2,309 genes across the chromosome and four plasmids (pREIS1 to pREIS4). …”

Water savings potentials of irrigation systems: global simulation of processes and linkages by Jägermeyr, J., Gerten, Dieter, Heinke, Jens, Schaphoff, S., Kummu, M., Lucht, W.

“…We find pronounced regional patterns in beneficial irrigation efficiency (a refined irrigation efficiency indicator accounting for crop-productive water consumption only), due to differences in these features, with the lowest values (< 30 %) in south Asia and sub-Saharan Africa and the highest values (> 60 %) in Europe and North America. We arrive at an estimate of global irrigation water withdrawal of 2469 km3 (2004–2009 average); irrigation water consumption is calculated to be 1257 km3, of which 608 km3 are non-beneficially consumed, i.e., lost through evaporation, interception, and conveyance. …”

Harvesting change: The impact of climate change on Africa’s agriFood systems by Piñeiro, Valeria, Gianatiempo, Juan Pablo, McNamara, Brian, Thomas, Timothy S., Traoré, Fousseini

“…Indeed, the continent emits 7 times less greenhouse gas compared to Europe and 15 times compared to North America (IPCC, 2023). In addition to rising temperatures, climate change affects Africa through several channels, including an increase in ocean levels, variations in precipitations (droughts and heavy rains), plant pests and animal diseases. …”

Toxoptera citricida (Kirkaldy) (Hemiptera, Aphididae) and its natural enemies in Spain by Hermoso-De-Mendoza, Alfonso, Álvarez, Almudena, Michelena, José Manuel, González, Pilar, Cambra, Mariano

“…T. citricida is present in most of the zones growing citrus in the world, but it was absent from the Mediterranean Basin and North America until middle 1990’s. Nevertheless, it was detected on citrus trees in 1994 in Madeira, in 1995 in Florida, in 2002 in Asturias, Spain (in yellow water traps), in 2003 in northern mainland Portugal, and in 2004 in southern Galicia, Spain, even though the three last detections were not published till 2005. …”
