“…Surprisingly, the model does not recognize suitability in Tindouf (west Algeria) where the presence of argan is naturalized or may be even spontaneous, and in any case a cultivated species (Kechebar et al 2013;Kechairi et al 2018). The unusualness of the environmental values of this area of southwestern Algeria is not very representative with respect to other larger areas, making these characteristics outliers and do not effectively train the suitability model.…”

“…In fact, there is evidence of this dispersion of argan in the Iberian Peninsula where it was cultivated during the historical period of Al-Andalus (VII-XV centuries) (Carabaza-Bravo et al 2004). There are other extensive regions in Argelia (northwest NW of the Tindouf region) where the argan grove is found in a spontaneous state (Kechairi et al 2018).…”

Bioclimatic habitat limitations for argan trees (Argania spinosa (L.) Skeels) in Northern Africa and Spain

et al. 2022

Argania spinosa L. Skeels is an Algerian-Moroccan endemic tree. This species is part of various plant communities consisting of Mediterranean, Macaronesian and Saharan floristic elements. It has been introduced and perhaps sometimes naturalized in various regions of the Mediterranean basin. Due to its role in combating desertification, high socio-economic value, and traditional use as fodder and food, the southwestern Moroccan argan grove (Arganeraie) was declared Biosphere Reserve. It had already been subject to conservation and reforestation programs a century earlier. Its cultivation for oil production could be, besides an economic objective, an effective method to conserve its genetic diversity. Therefore, this study aims to estimate its potential distribution and establish efficient breeding programs by determining its ecological requirements, identifying its different habitats, and predicting habitat suitability models for Morocco, Algeria, Tunisia, and Spain. Using 53 occurrence points, wind speed and direction data, and 29 bioclimatic variables, multivariate methods were applied to describe the ecological profiles and characterize the heterogeneity of its habitat to subsequently, train a Maxent model that establishes, besides Morocco and Algeria, suitable cultivation areas in Tunisia and Spain. The North African potential area is limited to the western Mediterranean coast of Algeria and flat and coastal areas of eastern Tunisia. The increased likelihood of suitability remains in the southeast Iberian Peninsula. A high probability of argan cultivation is also evident in the Canary Islands. These results provide possibilities for future expansion of argan crop and a window of opportunity to improve its genetic diversity and conservation.

The study of the morphological difference of 628 leaves of the argan tree Argania spinosa (L.) Skeelswas carried out by subjective sampling after a period of field data collection in spring 2017 through thevarious wilayas: Mascara, Mostaganem, Algiers, Bechar, Adrar, Tindouf. The objective was a varietalidentification of foliage through the bioclimatic stages. However a measurement of two biometriccriteria (length and width) was carried out, which shows a differentiation of forms between the samplesstudied by the significant differentiation at which with a low correlation R² = 27.2%, the effect of climateon the shape of the leaves is noticeably well represented.

“…Existen algunas especies que son endémicas de Chile y Perú (Henríquez, et al, 2012). Su descripción fenológica representa un ciclo bienal con floración tardía de los botones florales durante el período más caluroso del año (Kechairi et al, 2018). Muchas especies de Sapotaceae proporcionan productos económicamente importantes como el látex, madera y frutas para consumo humano (Rakotoniaina et al, 2018).…”

La fenología estudia los eventos periódicos en el ciclo biológico de la vida y cómo estos son afectados por cambios estacionales en el clima y es necesario conocer este proceso en Madre de Dios; por lo cual, el objetivo del estudio fue describir la fenología reproductiva de Sapotaceae de la cuenca del río Madre de Dios, Perú. Se evaluó la fenología mensualmente a 72 individuos agrupados en tres géneros de Sapotaceae entre enero y a gosto del 2007. Los resultados obtenidos demuestran que el género Pouteria presentó uniformidad en las fenofases productivas de botón, flor y fruto verde, con intervalos entre cuatro y cinco (60 - 100 %). La fenofase de producción más baja fue para Manilkara, pero superior a Micropholis con valor de dos, siendo desuniforme para Manilkara y Micropholis. Las especies monitoreadas no presentaron cambios en el follaje. La familia Sapotaceae inicia el periodo reproductivo a fines de la estación húmeda (marzo) y fines de la estación seca (agosto). Los picos elevados para botón y flor fueron entre marzo y mayo con valores fenológicos hasta cinco; para fruto verde el pico más alto se dio entre julio (61 - 80 %). La producción de fruto maduro está por debajo del resto de fenofases con valores de hasta dos como máximo.
