be able to say we know what’s causing the decline that we see in Mexico” The uncertainty could pose problems for conservationists trying to protect the butterflies The ambiguity is fueled in part by the monarch’s complex population structure and life cycle which includes a lengthy migration completed relay-style by several generations of insects (see graphic below) Each spring many monarchs head north from Mexico to the southeastern United States where they produce the first of up to three generations that can swell the total population The offspring then spend the summer feeding and breeding on milkweed throughout the northern United States and southern Canada In the fall a final generation makes the trek back to Mexico (Other regional monarch populations have different migration and breeding patterns) The cycle can make it hard to get a handle on summer and fall monarch numbers but researchers agree on one thing: Over the past 20 years the number of monarchs returning to the largest known wintering ground in central Mexico’s highland forests has plunged by more than 90% (Science 7 February 2014 p 583) Many have blamed the decline primarily on the expansion of herbicide-resistant crops in the summer breeding grounds which has led to the wide use of chemicals that kill milkweed But few studies have systematically examined monarch population trends in these areas A Cuadra/Science The new papers help fill that gap One draws on 18 years of monarch sightings collected by citizen scientists Between 1997 and 2014 at least some monarchs were spotted in all of the butterfly’s historical eastern breeding range (some breed in the far west) suggesting the summer population is hanging on And a second study relying on hourly monarch counts made by volunteers at hundreds of summer breeding sites between 1993 and 2014 found no statistically significant population trend up or down There’s “a disconnect” between those results and the wintering data Ries says That’s because if milkweed loss is driving the winter decline then summer populations seemingly should be shrinking too One possible answer Ries and others say is that the volunteers may have under-sampled agricultural areas hit hard by herbicides instead favoring sites popular with butterfly-watchers such as parks and protected areas Another view is that the last 7 or 8 years of the summer numbers do contain evidence—albeit statistically weak—of the monarch’s decline “If they had 9 or 10 years [of data] it probably would be [statistically] significant” contends entomologist Lincoln Brower of Sweet Briar College in Virginia who was not involved with the studies Other researchers say the egg-laying study suggests summer monarchs are struggling It found that monarch egg densities on milkweed plants have declined since 2006 “It’s pretty scary” says biologist and co-author Karen Oberhauser of the University of Minnesota Twin Cities “It probably means there aren’t enough monarchs out there to find the remaining patches” of breeding habitat The results have also put a spotlight on the need to better understand what is happening to monarchs during their fall migration south researchers say Two of the studies examine counts of migrating monarchs made from the mid-1990s to 2014 at stations in northern Michigan and Ontario Canada The Ontario tallies show a moderate decline whereas the Michigan numbers show no clear trend That suggests monarch deaths occurring farther south during the migration could be responsible for the sharp winter decline says ecologist Andrew Davis of the University of Georgia Athens a co-author of two of the papers Migrating monarchs run “a gauntlet of dangers” including predators parasites and even speeding cars he says “There is a tremendous amount of mortality and we don’t know how much” The biggest knowledge gap is for Texas Brower says which is in the middle of both the main fall and spring flyways Researchers “desperately” need monitoring data from that throughway he says Such studies could help ensure that government agencies and environmental groups focus their time and money on the right solutions Currently the US Fish and Wildlife Service and others have focused on conserving or restoring milkweed breeding habitat “But if the problem is that the monarchs are dying during the migration” Davis says “I’m not sure just trying to produce more at the start of the [fall] migration is the answer” Other steps such as protecting migratory pathways may also be needed The concerns over migration are real says ecologist Ernest Williams of Hamilton College in Clinton New York but “they should be added to—but not replace—the other issues we know to be affecting monarchs”Written by New York Times |
