Resistance of Rhipicephalus microplus to macrocyclic lactones represents a major challenge for the control of this ectoparasite, leading to substantial economic losses. The indiscriminate use of acaricides has resulted in increasingly resistant populations, highlighting the need for alternative control strategies and pharmacological approaches, such as the use of synergists to enhance acaricide efficacy against resistant ticks...

Biological invasions are globally recognized as one of the main drivers of biodiversity loss. Over the past four decades, there has been significant progress in understanding the mechanisms of alien species introduction into marine and estuarine environments. It is currently known that although humans can spread non-native species in various ways (e.g. aquaculture, vessel biofouling and oil and gas activities), ballast water i...

Diet analysis allows exploring how coastal dolphins interact with the environment and their role in the marine food webs. We studied the diet and feeding ecology of the Guiana dolphin, Sotalia guianensis , through analysis of stomach content from 42 animals stranded on the eastern coast of Brazil. A total of 1,336 semidigested prey items (fish, otoliths, cephalopod beaks, and crustaceans) were identified. Teleost fish comprise...

Coastal areas provide critical nesting habitat for marine turtles. Understanding how artificial light might impact populations is key to guide management strategies. Here we assess the extent to which nesting populations of four marine turtle species—leatherback ( Dermochelys coriacea ), olive ridley ( Lepidochelys olivacea ), hawksbill ( Eretmochelys imbricata ) and two subpopulations of loggerhead ( Caretta caretta ) turtles...
