We carried out the study in San Pablo Tejalpa, municipality of Zumpahuacán, Central México, in the Totláli Ecological Park (18 ° 51'43.9 "N and 99 ° 35'31.8" W; 1719 masl),
and in the adjacent fragment of tropical deciduous forest situated on a steep slope, both located.
The prevailing climate is temperate semi-warm-subhumid (A) C (W... |

In July 2021, in each count point, we recorded the height of the highest plant from each stratum (tree, shrub and herbaceous) within the ten-meter-diameter with respect to the center of the influence zone of the count point
Additionally, we took a fish-eye photography of the canopy in each count point as well as from the four geographic directions... |

ANONYMOUS; ANONYMOUS, 2024, "Effects of sex and arbuscular mycorrhizal fungi on root and cladodia traits of Oputia robusta from a dioecious population from Central-Eastern Mexico", https://doi.org/10.7910/DVN/HZNZ2N, Harvard Dataverse, V1
On December 28 and 29 2019, we obtained 17 male and 17 female last-level (counting from soil level) cladodes which length ranged from 19 through 25 cm, from individuals identified and tagged by their sexual form in our previous studies. The collected cladodes were less than eleven months old, that is, they grew from buds produced by the mother clad... |

Data obtained from the daughter cladodes produced from Opuntia robusta in greenhouses.
The variables measured throughout the experiment were the length (cm), width (cm) and thickness (cm) of each cladode produced.
These variables were measured every 30 days.
The mother cladodes were identified using their sexual form with a total of 12 males an... |

Modeling growth traits of Opuntia robusta cladodes: length, width and thickness, as well as the surface of both sides of the cladodes, their volume,
and the growth rate of the surface and volume in relation to their initial values.
1. Growth dynamics of the real sizes of colonized (AMF) or noncolonized (control), male or female Opuntia robusta... |
Czekaj, Łukasz; Janczur, Mariusz Krzysztof, 2020, "Replication Data for: Optimal defense traits in plants living in environments with different productivities: extending Coley, Bryant and Chapin's model", https://doi.org/10.7910/DVN/H6OAVG, Harvard Dataverse, V3, UNF:6:IDzxbDZQ0TR7j5xIxdyU+w== [fileUNF]
We present a mathematical model to solve an Optimal Control Problem for the optimal energy allocation to growth, reproduction and the production of defensive substances in plants. The substances produced repeal herbivores. |
