Four locals along a transect were sampled, involving soils with 5 and 100% of vegetal cover (L1 and L2, respectively) with Deschampsia+Colobanthus; bare alluvium soil (L3); and poor-drained moss (Sanionia uncinata) carpet with 100% soil cover (L4). Soil samples obtained from three layers and three replicates were submitted to chemical and physical analysis. Although both L1 and L2 are in the same nesting field, the more abundant vegetation at L2 promoted significantly larger (P < 0.05) total organic C (TOC) stocks in the soil than at L1 (43.08 and 9.03 Mg C ha –1 , respectively, at the 0-40 cm layer). Total N stocks increased from 2.60 to 6.54 Mg ha –1 for L1 and L2, respectively. Although the presence of seabirds represents an important transfer of organic material from marine to the terrestrial environment, the differences evidence the importance of vegetation in order to raise the soil organic matter levels. Soil pH was consistently lower in L2 than L1 - about 1.0 unit for the soil layers herein evaluated, which is probably linked to the soil organic matter accumulation. Contrary to the distribution of TOC and TN contents, exchangeable P and K had no gradient along the soil profile, evidencing that most of the P and K is native from the parent material and their input by seabirds to the soil is negligible. Keywords: organic carbon, total nitrogen, seabird field Introduction Soil chemical and physical attributes affect and are affected by the type and abundance of vegetal plants growing in the locality in a dynamic interaction. In ice-free regions of maritime Antarctica, such interaction is usually influenced by the presence of seabird colonies and by the heterogeneity of soil parent material (Navas et al., 2008; Simas et al., 2008), resulting in complex systems that are not fully understood (Ugolini & Bockheim, 2008; Vieira et al., 2012). For this reason, the purpose of the study was to evaluate the effect of soil cover by vegetation on the changes of soil chemical attributes in a skua field at Punta Hennequin, Shetland Island, Antarctica. Materials and Methods The study was performed in February 2011 in Punta Hennequin, Shetland Island, Antarctica (58° 23’ 21” W and 62° 7’ 41” S). Four locations along a transect were sampled: L1 and L2 consisted of a skua (Catharacta maccormicki) field with 5 and 100% of vegetal cover, respectively, distant from each other about 50 m, in the same moraine (same Science Highlights - Thematic Area 2 | 57
