Glycogen Plastids in Müllerian Body Cells of Cecropia peltata —A Higher Green Plant
Science, 1971A glycogen-containing plastid has been found in the cells of Müllerian bodies on Cecropia peltata (Moraceae) trees. Plastids in cells of the leaf blade, petiole, and stem are of the usual chloroplast type and contain starch grains only.

Cecropia peltata is popularly known as “guarumbo” in Mexico and is used in traditional medicine for treatment of diabetes mellitus. C. peltata plants were cultivated in a hydroponic system under controlled conditions. Gradients of light (20, 30 and 100 μmol m−2 s−1) and nitrate concentrations (13, 2 and 0.2 mM) were applied to estimate their effect on ...

Cecropia pachystachya Trec. (Urticaceae) is a common pioneer plant from South America, which is found on both degraded and preserved environments. Pioneer plants are able to disperse into agricultural environments and to introduce species of mites different from those present amongst the cultivated plants. This study evaluated the mite fauna present on

ABSTRACTMutualistic species often must survive periods of their development without their mutualist partner, but we lack a clear understanding of the ecological mechanisms that maintain mutualisms despite these gaps in partnership. In ant‐plant protection mutualisms, plants house ant colonies that deter herbivores.

The growth rate and food utilization efficiencies of penultimate instar Hyalophora cecropia are affected by restrictive feeding regimens which simulate the case of behaviorally induced larvae encountering a new food, and which entail an initial period of reduced consumption.

Biotropica, 1989
The association between Azteca ants and Cecropia trees is the most conspicuous ant-plant mutualism in the neotropics, yet little is known about the identities or community ecology of the species involved. A survey of ant communities found in Costa Rican Cecropia trees revealed a community of Azteca species obligately associated with Cecropia, and a ...

Plant defense against herbivores often involves constitutive and inducible mechanisms of resistance. Obligate ant-plants, which provide food and housing for ants, are thought to primarily rely on ants for defense against herbivores. This form of plant defense has largely been viewed as static.

Journal of Fluorescence, 2014
The physiological behavior of PSII measured by chlorophyll a fluorescence explains stress responses; wonders if it can differentiate plants from different populations. For this purpose, acclimated young plants of two C. pachystachya populations were cultivated from seeds. Chlorophyll-a fluorescence was measured after fertilization and [CO(2)](e).

Nature's pharmacy – how Azteca sp. ants keep their colony clean, using the host plant Cecropia sp.
2019The Cecropia–Azteca association is one of the most ubiquitous ant-plant mutualisms in Neotropical ecosystems. The plants provide ants with nesting space in their hollow stem internodes, as well as glycogen-rich food bodies for the ants to feed on. In return for shelter and food, Azteca ants protect the plant against herbivores and overgrowing vines ...
