A dataset on spatial distribution and association patterns of three species from moist semi deciduous forest
Knowledge on the spatial distribution and inter-specific association patterns in tree species is essential in plant ecology to understand ecological mechanisms and dynamic process operating in spatial distribution of a tree population in a plant community. We measured and compiled datasets on three tropical tree species from a moist semi deciduous forest. We used the software Programita to perform univariate and bivariate point pattern analysis by Ripley's L-function. These datasets can be used to inform on possibilities of interaction of these species in forest stands. These datasets can be also used to access the capacity of each tree of <i>Mansonia altissima</i> var. <i>altissima</i> A. Chev. to develop and grow or its exclusion probability within a plant community. <i>Mansonia altissima</i> A. Chev. is a plant species represented by only one-population in a moist semi-deciduous forest in Republic of Benin. Our project aims to understand its ecology for restoration and conservation purposes within its natural habitat as well as other habitats inside of its distribution range.

- Purpose
- <p>Context: <i>Mansonia altissima</i> A. Chev. is a species with economic value found in moist semi-deciduous forests of tropical Africa. The analysis of spatial distribution patterns can help understand the ecology of this species in forest stands dominated by emergent pioneer tree species like <i>Ceiba pentandra</i> (L.) Gaertn and <i>Triplochiton scleroxylon</i> K. Schum. <br> Aims: The main objective was to assess the spatial distribution patterns of <i>M. altissima</i> and spatial relationships with <i>C. pentandra</i> and <i>T. scleroxylon</i> in their natural habitat.<br> Results: Aggregations were detected in juvenile and premature <i>M. altissima</i>. Size and scales of spatial aggregation were inversely proportional to the DBH size. Inters-pecific associations were only significant at the similar life stages for <i>M. altissima</i> and <i>C. pentandra</i>. Both species were positively associated within radius ≥ 3 m. At non-similar life stages they displayed a repulsion or random pattern. <i>M. altissima</i> and <i>T. scleroxylon</i> generally displayed the independent distribution patterns at all life stages. <br>Conclusion: <i>C. pentandra</i> like pioneer could play the role of nurse plants in management of <i>M. altissima</i> populations providing them a moderate forest shade in large gaps for first years. </p>

- Statement
- <p>Spatial Point Pattern Analysis: The sampling design was constituted by ten (10) forest dynamics plots, one-ha each. A plot was divided into sixteen (16) consecutive subplots, 625 m² (25 m x 25 m), constituting the unities of data collection. All individual trees of <i>M. altissima</i>, <i>C. pentandra</i> and <i>T. scleroxylon</i> with a diametergreater than or equal to 1 cm were measured. The position of each tree was determined in two orthonormal vectors whose origin was fixed to upper left corner of each subplot. Geographical coordinates (x ; y) of a tree A within one-ha plot were determined as follow: A(x ; y) = (x_1 + x_0 ; y_1 + y_0). For trees belonging to the same subplot, distances x_0 and y_0 take the values 0 m, 25 m, 50 m or 75 m according to the position of the subplot (25 m x 25 m) within the one-ha plot. In each subplot, distances x_1 and y_1 define the position of a tree A in orthonormal vectors.<br> The attached metadata has is made from a CSV file named "dataset_full" containing a spreadsheet named "full" for full data of the three species.This dataset file contains five columns. The first "Species_names" contains the scientific name of species. The second column named "Life_stages" contains the three life stages of species. The third column named "DBH(cm)" contains the diameter at breast height, measured at 1.3 m above ground. The fourth and fifth column named "X(m), Y(m)" contain the geographical coordinates of trees. Note that another file named "figures" contains the summary statistics from analyses performed with file "dataset_full".<br> The file named "figures" contains four spreadsheets. The spreadsheet named "Mansonia_LifeStages" contains the summary statistics and spatial distribution patterns of <i>Mansonia altissima</i> var. <i>altissima</i> in each life stage. The spreadsheet named "associations_Masonia" contains the summary statistics and intraspecific association patterns of <i>Mansonia altissima</i> trees. The spreadsheet named "Masonia&Ceiba" contains the summary statistics and interspecific association patterns between <i>Mansonia altissima</i> and <i>Ceiba pentandra</i>. The spreadsheet named "Masonia&Triplochiton" contains the summary statistics and inter-specific association patterns between <i>Mansonia altissima</i> and <i>Triplochiton scleroxylon</i>.</p>
