Interspecific interaction may lead to species exclusion but there are several ways in which species can coexist. One way is by reducing the overall intensity of competition via aggregated utilisation of fragmented resources. Known as the 'aggregation model of coexistence', this system assumes saturation and an equilibrium number of species per community. In this study we tested the effects of i...

A complete understanding of how parasites influence marine ecosystem functioning requires characterizing a broad range of parasite-host interactions while determining the effects of parasitism in a variety of habitats. In deep-sea fishes, the prevalence of parasitism remains poorly understood. Knowledge of ectoparasitism, in particular, is limited because collection methods often cause dislodgm...

Abstract Bats use olfactory signals to provide information of species and individual identity quality. Males two long-nosed bats, Leptonycteris curasoae L. yerbabuenae , display an odoriferous dorsal patch during the mating season that is involved in mate choice. The documented serve as indicator male quality; for instance, males with present larger testes lower ectoparasite loads. We evaluated...

The study was conducted to assess the prevalence of veterinary ectoparasite cattle and goats in Brahmanpara, Burichong Debidwar upazila Comilla district. In total 560 animals (335 225 goats) were examined; among them 373 (217 156 found be infested with several species ectoparasites. Veterinary (cattle Brahmanpara showed highest (71.80%) lowest intensity (6.19). (55.47%) (12.20). Cattle (78.50%)...

Cetaceans are well-known for their intelligence, charismatic nature, and curiosity. Many species, particularly odontocetes, known to investigate manipulate novel objects they encounter. Yet, disentangling the drivers of these behaviors distinguishing between those that simply playful which serve a specific function remains challenging due lack direct observations detailed descriptions behaviors...

Hesperomyces virescens (Ascomycota, Laboulbeniales), a fungal ectoparasite, is thus far reported on Harmonia axyridis from five continents: North and South America, Europe, Africa, Asia. While it known that He. can cause mortality of Ha. under laboratory conditions, the role biotic abiotic factors in influencing distribution field unknown. We collected screened 3,568 adult 23 locations seven co...

Recent surveys and sample collection have conWrmed the endemicity of Dermanyssus gallinae in poultry farming worldwide. The reduction in number and eYcacy of many acaricide products has accentuated the prevalence rates of this poultry ectoparasite observed more often in non intensive systems such as free-range, barns or backyards and more often in laying hens than in broiler birds. The lack of ...
