Salamanders as rich prey for carnivorous plants in a nutrient‐poor northern bog ecosystem
“It was previously thought only tropical pitcher plants ate vertebrates. However, in the new paper published in the journal Ecology, biologists at the University of Guelph in Ontario describe finding Sarracenia pitcher plants in Algonquin Provincial Park that devour vertebrates, specifically salamanders.”

The intelligence of plants is not merely a shadow of human knowing, and their behavior is not a rudimentary form of human conduct. After all, unlike animal and humans, for whom behavior is most often associated with physical movement, plants behave by changing their states, both morphologically and physiologically. An honest approach to the capacities of plants thus requires a simultaneous acknowledgement of the similarities and differences between them and other living beings. In scientific circles, there is certainly no consensus on the implications of new research data drawn from the behavior of plant cells, tissues, and communities. On the one hand, the opponents of the Copernican Revolution in botany claim that the data do nothing but exemplify what has been known all along about plant plasticity and adaptability. This is the position expressed in the open letter to the journal Trends in Plant Science, signed in 2007 by 36 plant scientists who deemed the extrapolations of plant neurobiology “questionable.” On the other hand, we have the investigations of kin recognition in plants by Richard Karban and Kaori Shiojiri; of plant intelligence by Anthony Trewavas; of plant bioacoustics by Stefano Mancuso and Monica Gagliano; of the sensitivity of root apices as brain-like “command centers” by František Baluška and Dieter Volkmann; of plant learning and communication by Ariel Novoplansky; and of plant senses by Daniel Chamowitz, among many others. Their peer-reviewed research findings no longer fit within the scientific framework where plants are studied as objects, rather than living organisms. Leaving aside the provocative analogies they suggest between plants and animals, doesn’t the drastic change in approach (from plants as objects to plants as subjects) amount to a veritable Copernican Revolution, or Kuhnian paradigm shift, in botany?

During the Ice Age, Earth’s northern reaches were covered by chilly, arid grasslands roamed by mammoths, woolly rhinoceros and long-horned bison. That ecosystem, known by palaeontologists as the mammoth steppe, vanished about 13,000 years ago. It has no modern counterpart. Yet one of its plants has reportedly been resurrected by a team of scientists who tapped a treasure trove of fruits and seeds, buried some 30,000 years ago by ground squirrels and preserved in the permafrost (S. Yashina et al. Proc. Natl Acad. Sci. USA http://dx.doi.org/10.1073/pnas.1118386109; 2012). The plant would be by far the most ancient ever revived; the previous record holder was a date palm grown from seeds roughly 2,000 years old.

Adapting the absurdist metaphysical conjectures of Pataphysics (Alfred Jarry’s Science of imaginary solutions) to Botany creates a fantastic ecology of verdant pataphors. Metaflora, Phycological futurology and hypnogogic phyllotaxis perhaps? Libarynth invents and documents this new branch of speculative science and its related offshoots by ‘patafying’ the study of plants. Triffids take note! Maja Kuzmanovic and Nik Gaffney’s Cursory Speculations on Human Plant Interaction ‘explores the nature of surfaces and processes required to facilitate reciprocal interaction between humans and plants’. Examined in the paper: the continued evolution of human-plant symbiotics – in their somatic and syntactic protocols. This includes shamanic enthogenic communication and Thalient strategies.

Certain parasitic plant species form symplastic connections to their hosts and thereby provide an additional system for studying RNA trafficking. The haustorial connections of Cuscuta and Phelipanche species are similar to graft junctions in that they are able to transmit mRNAs, viral RNAs, siRNAs, and proteins from the host plants to the parasite. In contrast to other graft systems, these parasites form connections with host species that span a wide phylogenetic range, such that a high degree of nucleotide sequence divergence may exist between host and parasites and allow confident identification of most host RNAs in the parasite system.

We note that the style of the drawings in the Voynich Ms. is similar to 16th century codices from Mexico (e.g., Codex Cruz-Badianus). With this prompt, we have identified a total of 37 of the 303 plants illustrated in the Voynich Ms. (roughly 12.5% of the total), the six principal animals, and the single illustrated mineral. The primary geographical distribution of these materials, identified so far, is from Texas, west to California, south to Nicaragua, pointing to a botanic garden in central Mexico, quite possibly Huaztepec (Morelos). A search of surviving codices and manuscripts from Nueva España in the 16th century, reveals the calligraphy of the Voynich Ms. to be similar to the Codex Osuna (1563-1566, Mexico City). Loan-words for the plant and animal names have been identified from Classical Nahuatl, Spanish, Taino, and Mixtec. The main text, however, seems to be in an extinct dialect of Nahuatl from central Mexico, possibly Morelos or Puebla.

Plants that were frozen during the “Little Ice Age” centuries ago have been observed sprouting new growth, scientists say. Samples of 400-year-old plants known as bryophytes have flourished under laboratory conditions.
