Consistency in European seabass coping styles: A life history approach
Provedor de dados: 5
Autores: Ferrari, Sebastien; Millot, Sandie; Leguay, Didier; Chatain, Beatrice; Begout, Marie-laure.
Recent years have seen a growth of interest in the consistent differences in individual behaviour over time and contexts constituting so-called “individual coping styles”. An understanding of this inter-individual variation is essential to improve our knowledge of the adaptive value of behaviour. Coping styles may have implications in diverse fields, so the development of appropriate screening methods for each species appears to be the most effective way to extend our knowledge and to incorporate behavioural responses into selection-based breeding programmes, to improve the domestication and welfare of farmed fish. We tested 30 juvenile seabass (Dicentrarchus labrax) at least twice in individual-based tests (feeding recovery in isolation, aggressiveness,...

Immature life cycle of laboratory-reared Phylloicus elektoros and Phylloicus amazonas (Trichoptera: Calamoceratidae) from a central Amazonian stream
Provedor de dados: 36
Autores: MARTINS,Renato Tavares; SOARES,Kleicy Maciel; HAMADA,Neusa.
ABSTRACT We reared field-collected egg masses of the caddisflies Phylloicus amazonas (n = 2) and Phylloicus elektoros (n = 7) to adulthood. First instar larvae of both species hatched up to five days after field collection. Median development time from first larval instar to adult was 229 days for P. amazonas and 275 for P. elektoros, including the pupal development time (median of 13.5 and 16 days, respectively). Shredder organisms have been used frequently in studies related to organic matter processing in freshwater ecosystems. The biological information reported in here may be useful for the design of experimental studies in the field or under laboratory conditions.

Demographic structure of a threatened palm (Euterpe edulis Mart.) in a fragmented landscape of Atlantic Forest in northeastern Brazil
Provedor de dados: 39
Autores: Melito,Melina Oliveira; Faria,José Cláudio; Amorim,André Márcio; Cazetta,Eliana.
At the northern limits of the range of the palm species Euterpe edulis there is an endemic ecotype, known as the "Bahia" ecotype, which is distinguished by its reddish crownshaft and low seed production. Unfortunately, little is known about its demographic characteristics. Therefore, we contrasted the density of E. edulis populations in the Una region, in the southern part of the Bahia state, Brazil, with that of other populations of the species in southern and southeastern Brazil. In addition, within the Una region, we compared a long-protected forest fragment (F1) with three recently protected fragments (F2, F3, and F4), in terms of demographic parameters and plant size, in order to determine what influence, if any, time since protection has on E. edulis...
