Reading Time: 2 minutes

In the recently pubslished article “Ants’ diversity (Hymenoptera: Formicidae) in the Algeria’s humid forests, case of the Gerrouche forest massif (Taza National Park)” published in Sociobiology, Anissa Henine-Maouche, Abderrezak Tahraoui, and Riadh Moulaï study the local ant fauna in northeastern Algeria using four sampling methods. They detected 34 different ant species belonging to 15 genera and 5 subfamilies. They also observed species endemic to Algeria, Morocco, and Tunisia. Here, Anissa Henine-Maouche shares some pictures and videos of ants and of the fieldwork.

Sahel Islet is separated from the shore by a distance of approx. 7 meters. Its surface area is 0.2 ha with a maximum height of 15 meters (36°47′37.83′′N 5° 1′23.31′′E). (© Henine A.).

This islet is located only 100 m from the shore (Boulimat Beach), measures approximately 0.4 ha, and only half is covered with vegetation. This islet (36°48′54.91′′N 4°58′41.94′′E) is locally nicknamed as Garlic islet because its vegetation is dominated by large stems of the mainland summer flowering species Allium commutatum.

The El Euch island is also known as Doves Island. It is about 120 m from the mainland and covers an area of 0.8 ha with a maximum height of 20 m (36°53′33.17′′N 4°47′18.48′′E). (© Henine A.).
