Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic accuracy of the records, as well as the metadata. Moreover, we now provide an R packag...
Group‐living animals commonly display differences in behaviour, physiology and endocrine profiles between conspecifics within the group, which are tightly linked to reproduction. Teleosts exhibit a variety of social systems, where social status, as well as sex, has been linked to different androgen and oestrogen profiles. Levels of gonadal androgen and oestrogen were investigated as a function of sex and position in a social h...
Pelagic larval duration of 10 temperate cryptobenthic fishesNARA Subscribed
The pelagic larval duration ( D PL ) for 10 temperate cryptobenthic species belonging to three families: Gobiidae, Gobiesocidae and Blenniidae was investigated. Overall, the Gobiesocidae presented short D PL s varying between 11 and 18 days, the Gobiidae’s D PL ranged between 14 and 39 days, and Parablennius pilicornis (Blenniidae) had an average of 33 days (range 31–37 days). Two subtypes of settlement marks were found among...
First record of Chromogobius britoi (Teleostei: Gobiidae) on the mainland European coastNARA Subscribed
Chromogobius britoi is a recently described and poorly studied goby currently known only from the Macaronesian islands of Madeira and the Canarian archipelago. This species was captured for the first time on the Atlantic mainland coast of Europe (at Arrábida Marine Park, Portugal). The habitat, depth preferences and morphological characters of the species are revised.
Opeatogenys gracilis (Pisces: Gobiesocidae): an overlooked species or another ‘Mediterranean endemism’ found in Atlantic waters?NARA Subscribed
The occurrence of Opeatogenys gracilis outside the Mediterranean Sea is confirmed for the first time. This is probably a more common species than previously thought, but its apparent complete dependence on seagrass beds suggests the possibility of including it in the IUCN threatened species list. Some sex differences are described and a complete meristic and morphometric description of the species is presented. The occurrence...
