Species 2000 checklists

From the beginning of its monitoring programme, HELCOM took measures to evaluate and improve the recommended methods by intercalibrations between the different partners (HELCOM, 1983 Niemi et al., 1985 HELCOM, 1991). The HELCOM Phytoplankton Expert Group (PEG) takes care of quality assurance in phytoplankton methodology. It published a manual on biovolumes and size-classes of phytoplankton species in the Baltic Sea (Olenina et al., 2006), which is based on the species checklist of Hallfors (2004). We strictly use the species names given by Hallfors (2004). The autotrophic ciliate Mesodinium rubrum Myrionecta rubra) is counted to the phytoplankton.

The EPA said that similar criteria for other species have not been developed and data should be evaluated on a case by case basis. However, companies are reporting data on other environmental species, and conservative assumptions are made in the checklists for reporting in Chapter 20, Practice Tools. 

The most recent classification of mosses (Goffinet and Buck, 2004) and data from the Checklist of Mosses (http //www.mobot.org/mobot/tropicos/most/checklist.shtml [Crosby et al., 1999, update February 2000]), were used to estimate species-, genus- and family-level diversity in different lineages. To evaluate temporal variation in rates of diversification, an LTT plot was calculated based on the 100 calibrated phytogenies resulting from our age estimation analyses. 

Studies of floristic similarity were carried out using 43 areas selected as representing the major biomes of north-eastern Brazil Atlantic rain forest (mata atldnticd), savannas cerrados), upland rocky fields compos rupestres) and caatinga. In the case of the caatinga, areas that were different based on physiognomy, type of substrate and occurrence in different geomorphological units were included (Table 6.1). An additional criterion for selection of an area was the availability of voucher specimens to check identification. In addition to the species cited in the published checklists, other...

As they were extracted from floristic checklists for spedlic forest areas, the condensed information must be regarded as a means of assessing the floristic links between the main forest formations quantitatively and not as a register of actual figures for number of species, either total or in coimnon. 

The tree floras represented in the rain and seasonal forest checklists are similar in species richness 3009 and 2903 species, respectively. On the other hand, the number of rain forest checklists, 191, is considerably smaller than that of seasonal forests, 285, therefore suggesting that the species richness of the latter may actually be lower. In fact, the species/area curves of the two vegetation formations (Figure 7.8) demonstrate that, at any number of areas, the mean cumulative number of species is much higher in rain than in seasonal forests. The two formations also share a high proportion of tree species, 1814 out of 4098, or 44.3%, but both also have a considerable number of putative endemics, 1195 (29.2%) and 1089 (26.6%) for rain and seasonal forests, respectively.

The strongest affinities are among the Equatorial seasonally dry tropical forests and the inter-Andean seasonally dry tropical forests. The checklist data reveal 81 shared species between both areas. This link has been reported previously by studies of range data for plants (Bridgewater et al., 2003 see... 

Some projects which have contributed to floristic knowledge of the peninsula are the Etnoflora Yucatanense (Sosa et al 1985), an illustrated flora, and a recent checklist of the Peninsula (Duran et al 2000) which lists 2477 species in 992 genera of 182 families. This is an area which boasts a wealth of floristic and ethnobiological information, and also some of the largest forest reserves in Mesoamerica, although the proportion of SDTF in reserves is relatively small. 

Stevens etal., 2001 — present), and a series of guides to trees of Costa Rica from which information on SDTF could be gleaned with time and effort, but for rapid comparison of floristic composition of Central American and Mexican SDTFs, aside from species lists from vegetation and diversity studies, many studies have used Janzen and Liesner s (1980) widely available, informative and reasonably complete checklist of lowland Guanacaste Province (Figure 13.1). 

Continued floristic inventories, fundamental to understanding a site, are to be encouraged and supported in SDTF, as are the resulting checklists which indicate for each species the vegetation types or habitats in which it occurs, as has been done by Leon de la Luz et al. (1999), Perez-Garcla et al. (2001) and others.
