Aspectos Ambientais Das Áreas Susceptíveis À Desertificação E Características Socioambientais Do Núcleo De Desertificação Do Seridó Do Rio Grande Do Norte (Rn) E Paraíba (Pb)

Abstract: Apesar da relevância, as discussões e a disseminação de informações, a execução de medidas para o enfretamento da desertificação praticamente não têm sido executadas. Neste sentido, este trabalho visa apresentar uma síntese de informações sobre os aspectos ambientais das áreas susceptíveis à desertificação no Semiárido brasileiro e apresentar as características socioambientais relacionadas mais diretamente com a desertificação no Seridó do Rio Grande do Norte e Paraíba. Para tal, foi realizada pesquisa onde se… Show more

“…If the distinction in haplotype composition can be attributed to some degree of genetic isolation, the differentiation between MA and RN populations could be attributed to the Parnaíba Delta (2.7° S), located between them, outflowing freshwater, and suspended sediments (Figure 1). The abiotic conditions related to temperature and salinity are also distinct between MA and RN: 35 (salinity) and 27-29°C for MA, and 38-50 (salinity) and 28-37°C for RN Lucena, 2012;Santiago et al, 2005). Therefore, these environments could induce the selection of individuals suitable to inhabit each region's microhabitats leading to long-term local adaptation and ecological specialization.…”

“…Environmental stresses, such as the increase in desertified regions and degraded areas within irrigated perimeters, are frequently observed in the context of the BSR [17][18][19][20][21][22][23]. These tensions are predominantly caused by anthropogenic and natural actions, resulting in soil degradation and loss of agricultural land, especially in the BSR, which is inherently sensitive to erosive processes due to its sparse vegetation and concentrated precipitation regime [24][25][26][27].…”

“…Although the mangrove population developed unique adaptive characteristics that allowed these individuals to establish themselves and survive in this environment, they also adapted to this site at the cost of metabolic losses, which ended up compromising growth. Comparing both environments, mangrove (RN) has salinity that varies between 38 (near the mouth) to 50 (near the end of the system upstream) and temperature between 28 and 37°C (Santiago et al 2005;Lucena 2012). In contrast, rocky shore populations (MA, BA, SP1, and SP2) have stable salinity of 35 and temperatures between 20 and 26°C at the southern coast and between 27 and 29°C at the northeastern coast.…”
