Data on leaf area, shoot number, and height of reproductive H. acuminata
This repository is to clean and organize data on leaf length, leaf area (individual leaves, total plant leaf area), shoot number, and height of Heliconia acuminata plants found at reserve 1501 of the Biological Dynamics of Forest Fragments Project (Manaus, Brazil).
The data are from a pilot study testing for costs of reproduction in H. acuminata conducted during 1998-1999 field season. Plants were assigned to one of four treatments: (1) fertilizer addition + manually hand-pollinate all open flowers with pollen from other plants, (2) Manually hand-pollinate, (3) fertilizer addition, (4) Control plants. At the time I knew relatively little about H. acuminata growth and reproduction; I soon realized the treatments were unlikely to be effective because of the way the fertilizer was being applied and the difficulty I was having hand pollinating plants. However, the data set has value for its detailed breakdown of plant allometry. For each plant I measured:
- Height to the top of the tallest leaf
- Number of shoots
- The length of all leaves
- Production of flowers, fruits, and seeds
Using No. 3 one can then calculate:
- Total leaf number
- Area of each leaf (using the regression equation found in Bruna et al. 2002)
- Total plant leaf area
This repository has the raw data (data_raw
), the code used to clean and organize it (in the r_code
folder) and the clean data (data_clean
).
The clean data has the following columns
-
plant_id: plant's unique ID Number.
-
trt: experimental treatments.
-
yr: year in which measurements conducted
-
mo: month measurements made (1= January, 8=August)
-
trt: experimental treatment applied at whole-plant level
(a) fert_pollen = fertilizer addition + hand pollination (b) pollen = hand pollination / no fertilizer addition (c) fert = fertlizier addition / no hand pollination (d) control = no fertilization, no hand-pollination)
-
shoots: Number of vegetative shoots a plant had
-
ht: height of the plant
-
lvs: no. of leaves the plant had
-
total_la: total plant leaf area (i.e., sum of individual leaf areas)
-
flrs: number of flowers the plant had in (1998 repro season)
-
dev_frts: number of developing fruits the plant in the 1998 repro season, if flowers produced
-
frts_collected: number of fruits collected from the plant in the 1998 repro season (can be NA because no dev_fruits, or because none collected)
-
sds_collected: number of seeds collected from the plant in the 1998 repro season (can be NA because no flowers produced, or none collected)
-
sds_per_fruit: number of seeds per fruit in the 1998 flowering season (can be NA because no flowers produced, or none collected)
**Note the numbers of dev_fruits will be NA when no flowers produced)
