“…Major progress has been made in understanding butterfly (Malcolm 1987) and moth migrations on the population level, such as in the oriental armyworm (Mythimna separata; Chen et al 1989), the rice leafroller (Cnaphalocrocis medinalis; Riley et al 1995) or the black cutworm (Agrotis ipsilon; Showers 1997). Dragonfly migration occurs on all continents except Antarctica, and is also a well-documented phenomenon (Russell et al 1998;Corbet 1999;Moskowitz et al 2001;Freeland et al 2003;Artiss 2004). Atleast 25 to 50 of the approximately 5200 dragonfly species worldwide are thought to be migratory (Russell et al 1998).…”

“…Approximately nine dragonfly species are common long-distance migrants in North America, flying annually north and south throughout much of the North American continent (Macy 1949;Turner 1965;Opler 1971;Arnaud 1972;Russell et al 1998;Moskowitz et al 2001;Sprandel 2001). Migrating Green Darners have even been recorded in the Gulf of Mexico on oil platforms (Russell 2005).…”

Every year billions of butterflies, dragonflies, moths and other insects migrate across continents, and considerable progress has been made in understanding population-level migratory phenomena. However, little is known about destinations and strategies of individual insects. We attached miniaturized radio transmitters ( ca 300 mg) to the thoraxes of 14 individual dragonflies (common green darners, Anax junius ) and followed them during their autumn migration for up to 12 days, using receiver-equipped Cessna airplanes and ground teams. Green darners exhibited distinct stopover and migration days. On average, they migrated every 2.9±0.3 days, and their average net advance was 58±11 km in 6.1±0.9 days (11.9±2.8 km d −1 ) in a generally southward direction (186±52°). They migrated exclusively during the daytime, when wind speeds were less than 25 km h −1 , regardless of wind direction, but only after two nights of successively lower temperatures (decrease of 2.1±0.6 °C in minimum temperature). The migratory patterns and apparent decision rules of green darners are strikingly similar to those proposed for songbirds, and may represent a general migration strategy for long-distance migration of organisms with high self-propelled flight speeds.

“…Butterflies are known to establish populations in new countries as a consequence of crossing oceans on severe weather fronts (Fox, 1978; Clarke & Zalucki, 2004). Large displacements of monarchs have been associated with hurricanes in the USA (Moskowitz et al ., 2001) and Europe (Anonymous, 1995).…”

Monarchs across the Pacific: the Columbus hypothesis revisited

The 'Columbus hypothesis' suggests that the annual north-south return migration of Danaus plexippus in North America is a very recently evolved behaviour, less than 200 years old. This hypothesis rests, in part, on an analysis of the 19th century spread of the monarch across the Pacific that assumes a continuous east to west movement and is based predominantly on one publication. We review all the contemporary literature and present new analysis of the data. The movement of the monarch across the Pacific in the second half of the 19th century is best explained by a model which involves no more than three spot introductions, directly or indirectly aided by human movement, followed by natural spread of the monarch across island groups. Contemporary records refer to 'boom' and 'bust' population cycles on newly settled islands, which may have led to high rates of monarch movement. We see no evidence in the records to suggest an east to west sweep by monarch populations as suggested by the Columbus hypothesis.

“…While co-location advocates assert the benefits of such extensive borrowing (Moskowitz, 2015b), Lipsitz reminds us that “compared to white Americans, people of color—more likely to be poor or working class—suffer disproportionately from these changes” (Lipsitz, 2006:17). As the city responds to bond ratings with cuts to public sector jobs, Black men and women suffer higher rates of firing and unemployment than their White peers.…”

“…In addition, because the median income for Black households is 60 percent that of White families, such cuts exacerbate already existing obstacles to Black homeownership and retirement savings—the two chief ways White families accumulate wealth (Cohen, 2015). While for Eva Moskowitz (2015b), private investors are “people who are generous and feel that education should be a human right and a civil right,” it remains that debt financing empowers elites to reshape cities in ways that advance their accumulation desires, resulting in a profoundly racialized uneven development (Dumas, 2015; Hackworth, 2007; Lipsitz, 2011; Sassen, 2001; Smith, 2010). Co-location expands debt financing of education, further consolidating the power of elites over urban school governance while funneling millions of dollars into financial corporations and their beneficiaries.…”

‘We don’t care who you are’: Race, space, and dispossession in New York’s charter school co-location reform

In the United States, charter school proliferation remains a top priority for neoliberal education reformers and their private sector allies. Such schools are owned and run by private operators yet receive public funding, resulting in large transfers of public assets into private hands. Co-location facilitates this process by providing charters rent-free space within existing public school buildings. The author argues that New York’s 2014 co-location reform, which guarantees co-location or rental assistance for the city’s charter schools, produces school space in ways that create new circuits for the accumulation of capital by the private sector, while at the same time putting into circulation hegemonic imaginations of the relationship of race to school space. Co-location reform enlists school space within neoliberalism’s color-blind and meritocratic racial ideology: reformers like New York Governor Andrew Cuomo “don’t care who you are” because achievement is seen as the result of hard work and good choices made in free markets, and co-location will extend educational markets to families of color who have heretofore been excluded. Using the co-location of Success Academy Charter Schools as a case, the author argues that co-location reform, animated by a “white spatial imaginary,” both obscures and exploits the racialized process of organized abandonment that underwrites neoliberal capitalism.
