Flowering…A Reason of Their Own:  A Look at Agave Flowers, Structure and Relationships


This is one of the lower umbels, the second peduncle from the bottom. The others contain more individual flowers. This umbel was caught in the stage where the filaments are collapsing and the styles extending. Nectar has spilled to many surfaces. The tepals have begun to shrivel as well. Coarse pollen grains show on the anthers with some ‘spilled’ to other surfaces. Individual flowers aren’t particularly pretty.

Flowers can be ‘incidentally’ beautiful.  We often selfishly view them as products of nature intended to fulfill our own hunger for beauty, failing to recognize them for what they are, living organic structures evolved over time to continue their own species, organs and tissues meant to attract the necessary attentions of pollinators, to produce the seed of generations to follow. We, as a society, have learned to view a select few of these as beautiful.  We respond to them in a way not unlike the pollinators themselves do, and by either ignoring them or focusing our attention upon them, we too alter their future form and their very existence.  Sometimes we do this more directly through choosing the plants we want around us.  Other times it is our indifference that seals the fate of a plant or landscape, especially when the flora is unable to grab our often preoccupied attention and we clear land for development wasting all of the ‘lesser’ weedy natives we’ve learned to undervalue, or, through our efforts to ‘improve’ plants by controlled breeding and hybridization, intentionally altering their form even the conditions under which they will grow.  Sometimes, in our desire, for fashion and an idealized beauty, we attempt to control and remove that which we don’t want, creating sterile flowers, the antithesis of what a plant would ‘want’.  We select for bloom size, scent and color, for period of bloom, we seek to increase the number of petals and alter the pattern they may be held in, even the lifespan of the individual flower, the height of the plant so that it doesn’t flop over, the ability to grow it in more sun or shade, the shape and color of leaves and the form of the whole plant.  We attempt to control all of this and crank out a uniform product that can be ‘plugged’ into landscapes and gardens as desired.  Plants with dependable performance characteristics, a pedigree.

We need to remember that this is what we ‘want’, not what the plants ‘want’, nor is it necessarily in their best interest as either a species or a member of a plant community.  These days most of ‘us’ aren’t gardeners.  Our relationships with nature were broken long ago.  It is difficult to see the critical connections in nature, between plants and the organisms they have evolved with, upon which they are dependent, especially if someone is not looking.  It is even more difficult to see where we ourselves fit into this in our materialistic, consumer society where so many of us measure ourselves and others by the things and property we own…and are quick to ‘take’ from others.  I’m going to paraphrase a snarky rejoinder I’ve heard these last several years, ‘Yeah, you’re special, just like everything else!’ and I mean this in the broadest sense.

This is the second and last installment of my look at Jon Entine’s articles and the strategies he employs.  Here is a link to the first of my postings on this.

Part II: Bee Deaths And CCD – Flawed Chensheng Lu Harvard Studies Endanger Bees

By Jon Entine | November 24th 2014

Last week, in Part I of this two part series, “Bee Deaths Mystery Solved? Neonicotinoids (Neonics) May Actually Help Bee Health”, we explored the claims by Harvard School of Public Health researcher Chensheng Lu, heralded by anti-pesticide and anti-GMO advocacy groups, for his research that purportedly proves that the class of chemicals known as neonicotinoids are killing bees and endangering humans. And we saw how many journalists, our of ignorance or for ideological reason,s promote dicey science. 

(Some advocacy groups have latched on to Lu’s work looking for legitimacy and support. There has been a growing community of resistance to much that has been going on in the agro-chem-gentec industry that pre-dates Lu and his research. They have been challenging the multi-billion dollar industry on multiple fronts. On the other hand, it only takes a little checking to discover that Lu is often viewed as a ‘liability’ within the scientific community and a hinderence to their efforts by many in the community who have been advocating for good science in the political process that regulates these industries. They did not choose Lu nor do they now claim him as their champion. Entine, in his previous article strategically chose Lu as a ‘straw dog’ to represent his opposition, the “anti-pesticide and anti-GMO advocacy groups”, a target that he could then ‘tear down’ and then apply to the opposition groups as a whole, as if Lu, with his biases and ‘sloppy science’ were truly representative of them. In these articles, at least, Entine gets to choose. This strategy is becoming increasingly common when ‘industry’ and their front men, under attack, seek to ‘confuse’ the public thus reducing political pressure that might seek to limit them and their ability to conduct ‘business as usual’.

The following posting is built around an article written by Jon Entine in response to Chensheng Lu’s claims that Neonicotinoides, synthetic Nicotine, a commonly used ‘group’ of insecticides in modern conventional agriculture, are at the heart of CCD.  There is a link to the original Entine article posted on his site, the Genetic Literacy Project ,it also appears, on the Science 2.0, website.  There is a second Entine article as well addressing more directly Lu’s ‘science and Entine’s conclusions that I will deal with in a later posting.   I began this after reading it several weeks ago on Facebook and was initially, convinced by it that Lu was in fact practicing bad science and that bothered me, because Entine’s article was ‘pushing’ me so hard to get to that conclusion.  Later, the topic kept popping up on my radar as I saw calls for bans of neonics here in the US.  I more recently was puzzled by what I found on the Xerces Society website regarding the issue…so I decided to look a little deeper.  What follows is still a beginning, an attempt to winnow the ‘wheat from the chaff’.  There are many more questions to ask if we are to make a responsible decision on this issue.  Such things are never simple when fallible humans and corporations are involved.
