ISBN Fikret Berkes and Carl Folke brought together a remarkable group of people and organized their scholarly work to produce a splendid volume that marries the best research on social and ecological systems that exists today. Since I received this book in April of , I have not only read all of the chapters in it, but I have drawn heavily on several of the key chapters in the research papers I have been writing. Thus, it is a challenge to know how best to do a short book review of a volume that is this rich in theoretical and empiri- cal insights. Instead of simply bringing brilliant scholars together for one conference and then publishing a book that is little more than the proceedings of a conference, Berkes and Folke prepared a central framework for the entire effort. Authors partici- pated in three workshops held at the Beijer Insti- tute of the Royal Swedish Academy of Sciences to discuss and improve on the framework and to improve the linkages between the individual cases and the framework.
However, despite the high density of U. Population density estimates of semiterrestrial crabs based on burrow counts tends to overestimate the density if no care is taken to discard the number of unoccupied galleries or consider those with multiple openings as single ones MACINTOSH, ; MACIA et al. The denser vegetal covering near the channel Band I explains the lower average temperature than that observed in the upper mangrove area Band IV where the vegetal covering was less dense CARMO et al.
Temperature can be used as an important indicator of crab behavior, can explain their low mobility and smaller captures in the winter months than in the summer when they are more active GOES et al.
The low winter temperatures also affect the gallery-closing behavior of the crabs, which use this period to perform the ecdysis inside and determine the period of change of the species. This study confirms the data obtained by Pinheiro and Fiscarelli h and Wunderlich et al. Differences between periods may occur between mangrove areas by virtue of contrasts in latitude and vegetation, an interesting aspect which calls for further analysis.
However, more uniform levels of water salinity are to be found inside the closed burrows see interstitial salinity values than in the open ones that are more subject to the influence of tides and rainfall.
Hattori reports a positive association between the salinity values of burrow water and the density of U. The significant negative association between the total number of galleries and the silt and clay found in this study was similar to that reported by Hattori , although the latter author has made use of density as the dependent variable, with no statistical significance.
Sediments with finer particle size are easier to dig for crabs, but provide less stable galleries, thus explaining the association of these constructions by U. In this regard, the association between particle size, rooting and flooding in mangroves may also influence the scavenging depth of Ucides cordatus, reaching more than 2 m deep in some places, as previously reported by Nordhaus et al.
According to those authors, despite the latitudinal variation due to the influence of temperature, photoperiod and precipitation, the reproductive season of this species lasts for months, usually from November to May, which is consistent with the results of this study.
This assertion is supported by the distribution of individuals by size class, in which a significant predominance of females between mm may be related to this fishing effort aimed specifically at males.
The maximum crab sizes CW registered in the present study males, It is therefore to be hoped that the results obtained by this study may strengthen the perceived need for the planning and management of the harvesting of this species.
