An ant supercolony is a very large entity with very many queens. Although normal colonies of small extent and few queens remain distinct, a supercolony is integrated harmoniously over a large area [1, 2]. The lack of aggression is advantageous: Aggression is costly, involving direct and indirect losses and recognition errors [3, 4]. Indeed, supercolonial ants are among the ecologically most suc...

In this study, the diversity of thrips (Insecta: Thysanoptera) on two varieties olive trees (Chemlal and Sigoise) in northeast Algeria (Province Batna), was evaluated for 3 years (2019–2021). addition, fluctuations numbers phytophagous were estimated according to phenological stages. A total 19 species are identified (Liothrips oleae) have just been reported first time Algeria. Only 5 females c...

Understanding how biodiversity will respond to future climate change is a major conservation and societal challenge. Climate change is predicted to force many species to shift their ranges in pursuit of suitable conditions. This study aims to use landscape genetics, the study of the effects of environmental heterogeneity on the spatial distribution of genetic variation, as a predictive tool to ...

Research into biological control of Mikania micrantha Kunth (Asteraceae) started in 1978, concentrating on insect agents. Host specificity studies on the first agent, Liothrips mikaniae (Priesner) (Thysanoptera, Phlaeothripidae) from Trinidad were completed by 1982, and the thrips was released in the Solomon Islands in 1988 and, subsequently in Malaysia in 1990. Neither release led to establish...

Recent discoveries of several new, cryptic bat species in Europe, and the growing importance of bat conservation have resulted in an increased research effort to study roost site selection, habitat use and spacing/foraging behaviour of (rare) bat species (Arlettaz, 1999; Mayer and von Helversen, 2001; Mickleburgh et al., 2002; Di Salvo et al., 2009; Whitaker and Karataş, 2009). In fact, before ...
