About the genus · Artocarpus

Artocarpus is a genus of approximately 60 trees and shrubs of Southeast Asian and Pacific origin, belonging to the mulberry family, Moraceae. Most species of Artocarpus are restricted to Southeast Asia; a few cultivated species are more widely distributed, especially A. altilis (breadfruit) and A. heterophyllus (jackfruit), which are cultivated throughout the tropics.

Cultivation

Seasons

The rain rule reads a summer growing season: 70% of the median year's rain (2,144 mm of 3,051 mm) falls in June to November, warmer than the year (wet-season mean 26.8 °C against a yearly mean of 25.4 °C). Months are the habitat's, northern hemisphere; shifted six months for a southern-hemisphere collection: December to May.

Rain

3,051 mm in the median year at the habitat, 2,144 mm of it June to November. Wettest month August at 420 mm, driest month April at 66 mm. Across the grid cells of the range the year's total runs 2,765 mm to 4,129 mm, the 10th to 90th percentile of each cell's own year. The median of the cells' own yearly totals, 3,045 mm, is the year's rain at the top of the page; the 3,051 mm here is the median year's, the twelve monthly medians added, which the rain rule reads. Habitat calendar, northern hemisphere; median year across the grid cells of the range, CHELSA.

Light

Open sky over the habitat: 19 to 39 mol/m²/day across the year (daily light integral, median year across the grid cells of the range, CHELSA; the lowest 10th-percentile month across the cells is 18, the highest 90th-percentile month 39).

Warmth and air
Temperature

Monthly means: the coldest month's mean nightly low 21.4 °C in January (across the grid cells of the range 20.0 °C to 21.7 °C), the warmest month's mean daily high 28.4 °C in July (median year across the grid cells of the range, CHELSA). Cold floor: none read. The nearest figure is 21.4 °C, the coldest month's mean nightly low, January, in the median year (CHELSA); a month's mean of its nightly lows is warmer than the nights a floor is read from. The daily extremes were read at a weather cell that is mostly sea and are not used.

Humidity

Relative humidity at the habitat: 60 to 68% across the year (monthly means, median year across the grid cells of the range, CHELSA). A figure about the air, saying nothing about how the plant takes water.

How this section is made

Each card states this species' habitat figures with their sources, and what two fixed rules read from them; nothing here says what the plant does, wants or tolerates. The rules · the terms.

Seasons. Read from the median year of CHELSA monthly rainfall and mean temperature across the grid cells of the range: the rain rule takes the smallest set of months carrying 70% of the rain and calls it winter when its mean is more than half a degree below the year's, summer when more than that above, and neither in between; the temperature rule, used only under 120 mm, names the cooler six months when they are at least a degree cooler than the other six. Months are shifted for the other hemisphere only where the temperature curve moves 4 °C or more and the habitat lies 10° or more from the equator. A reading of the curves, not an observation of the plant.

Rain. CHELSA monthly precipitation, median year across the grid cells of the range. The rain that falls where the species is recorded; nothing about how the plant takes water.

Light. CHELSA shortwave radiation at each envelope cell, a daily-mean flux taken to a daily total and converted at 2.07 mol of PAR per MJ. The sky over the habitat, measured; what reaches a plant under a rock, a shrub or a shade cloth is not.

Temperature. CHELSA monthly means, median year across the grid cells of the range. No cold floor is read without a daily extremes series; the coldest month's mean nightly low named in its sentence is not one. Not a measured survival limit for any plant in a pot.

Humidity. CHELSA relative humidity, median year across the grid cells of the range.

Climate across the habitat

From few records: this habitat climate is read from 8 records in 5 grid cells; a page says so under 12 records or 5 cells, and shows the figures as read.

The daily extremes were read at a NASA POWER cell that is 4% land: neither it nor the next candidates whose coldest month's mean nightly low is within 2 °C of the median across cells sit in a POWER cell that is mostly land, and the rule reads a cold floor only from a cell that is mostly land, so none is read for this species. Nor is the coldest month's mean nightly low taken as one: it is a mean of a month's lows, not its coldest night. What that cell gave over 44 years: absolute minimum 15.8 °C, 1st-percentile night 19.2 °C, 99th-percentile day 29.2 °C.

How this section is made
Each figure is the median across the 5 grid cells holding the 8 in-range records, with the 10th–90th percentile span across those cells after the slash where it differs. A dash is a month one or more of those cells has no figure for in the grid (a variable CHELSA does not carry there), so no median is taken rather than one over fewer cells. Extremes and elevation were read at a typical spot in the range, cell 1383:6037 (20.825, 121.875). Normals: CHELSA V2.1 1981–2010 climatology, 0.05° cells (each the mean of ~36 1 km pixels). Across the range: median and 10th–90th percentile of each month across the 5 distinct grid cells holding 8 of the 8 in-range records; extremes and elevation at the typical cell 1383:6037 (its coldest month's mean nightly low nearest the median across cells, though its NASA POWER cell is only 4% land and none of the 4 next candidates within 2 °C of the median was mostly land); its position is the cell centre. Extremes: NASA POWER (MERRA-2) daily 1981–2024, cell 21.00_121.875, lapse-corrected +132 m at 6.5 °C/km. Elevation: ETOPO 2022, 134 m (cell mean).

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing: the climate was read across the cells of the in-range records placed well enough to read one, not at the marker.
Openly licensed records inside the range, framed on where they fall.

This species has no GBIF key of its own. Its records are GBIF's under the key of the name Kew's World Checklist holds as this plant: 3763957 (Artocarpus xanthocarpus Merr., 37 records). No name was matched to GBIF; the keys are read from Kew's synonymy. How.

Evidence usedThe map marker rests on all 22 georeferenced records inside the native range; the climate across the range on the 8 of them placed to within 10 km; the map shows only the 5 openly licensed ones, which alone would put the marker 1 km away. 1 record outside the WCVP native range not used. Under a dozen records behind the climate. 14 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.
Other GBIF keysRecords also from GBIF's key 3763957 (Artocarpus xanthocarpus Merr.): Kew's file holds it as Artocarpus xanthocarpus Merr. (accepted); 37 records, from GBIF's download.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population of the 22 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 5 datasets via GBIF.org; each carries its own licence.
