Abstract This synthesis is framed within the scope of Brazilian Benthic Coastal Habitat Monitoring Network (ReBentos WG 4: Mangroves and Salt Marshes), focusing on papers that examine biodiversity-climate interactions as well human-induced factors including those decrease systemic resilience. The goal to assess difficulties related detection climate early warning signals from monitoring data. We also explored ways circumvent some obstacles identified.

The objective of the study was to estimate frequency recurrent falls and identify main associated risk factors. BRAZOS is first epidemiological performed on a representative sample Brazilian population. Anthropometric data, living habits, previous fractures, falls, dietary intake, physical activity quality life were evaluated in 2,420 individuals aged 40 older. Recurrent reported by 15.5% men 25.6% women. Among women, factors significantly age, fracture, sedentary lifestyle, poor life,...

The relationship of wet weight (WT) to cephalothorax width (CW) and temporal seasonal variations in the condition factor were analyzed for each sex mangrove crab Ucides cordatus, using specimens collected monthly from September 1998 through 2000, at Iguape, state São Paulo. WT/CW relationship, determined by regression analysis evaluated individually, seasonally, sex. indicated isometric growth males negative allometric females. Body was higher than females equivalent size this difference...

The reproductive biology of Arenaeus cribrarius from Ubatuba, São Paulo State, Brazil, was studied. Swimming crabs were sampled monthly for two years with otter trawls in bays. A total 941 males and 1,012 females examined. Mating took place mainly autumn involving postmolt intermolt males. At that time, gonad regression verified adult males, due to spermatophore transfer, the molting females. Ovigerous or mature gonads present year-round but more frequently captured during spring summer. We...

During monthly samplings between September 1998 and August 2000, 3,660 specimens of Ucides cordatus (Linnaeus, 1763) (2054 males 1606 females) were obtained examined for size (CW = carapace width) to determine growth-age equations each sex. This species showed a slower growth, with marked seasonal oscillation, in females as compared males, suggesting application the nonseasonal von Bertalanffy growth model, respectively. |${CW_\infty }$| |$k$| constant closely similar two sexes...

Abstract Arenaeus cribrarius is a mainly tropical crab that occurs in the Western Atlantic Ocean, Brazil being its type-locality. The species ranges from Vineyard Sound, Massachusetts, USA to La Paloma, Uruguay. Information about this scarce. relative growth ofA. was analyzed, based on some morphometric relations, where carapace width, excluding lateral spines (CW), used as an independent variable. A total of 403 specimens (189 males and 214 females), collected Ubatuba, State São Paulo,...
