“…For example, they more efficiently used Mg > P > K > Ca > N. The usage efficiency of P, K and Mg differed between species (Table 5). This variation in efficiency may be related to the nutrient's availability in the soil or may be an intrinsic characteristic of the species (Albuquerque et al, 2018).…”

“…Leaves are the organs which best reflect the nutritional status of plants (Malavolta, 2006). Thus, the nutritional efficiency of the species evaluated by the leaf biomass production is more adequate than an evaluation through the production of stems and branches, mainly for nutrient cycling studies (Albuquerque et al, 2018). According to Vitousek & Sanford (1986), the mineral nutrient content in leaf tissues may reflect the soil's fertility, being useful to compare the nutritional condition of different areas.…”

“…Despite the poor fertility of the soil (Kaspari et al 2008), the microbial community decomposing leaf litter is responsible for nutrient cycling and facilitating nutrients availability from the leaf litter which is the main source of organic matter (Costa et al 2010;Stahl et al 2013;Albuquerque et al 2018). Fungi, especially conidial fungi, are capable of decomposing leaf litter.…”

Brejos de Altitude are enclaves of higher altitude humid forests in the semiarid lowlands of the North-eastern of Brazil. They present unique characteristics in terms of soil and air humidity, temperature, vegetation cover, and biodiversity. Due to these conditions, many cattle ranchers and farmers develop activities that have caused habitat loss and fragmentation of biodiversity. In this study, we aimed to describe the diversity of conidial fungi that occur in the leaf litter of the riparian vegetation in a Brejo de Altitude in Pernambuco, Brazil. Decomposing leaf material was collected from the forest floor in the dry and rainy periods of 2019, incubated in moist chambers and observed daily for fungal structures, for up to 45 days, under dissecting microscope and light microscope. Eighty-four taxa of fungi were identified, totaling 335 occurrences. The air and soil temperature, and precipitation showed an influence on the fungal community. Species richness was greater in the dry period and abundance was greater in the rainy period. The multivariate analyses revealed differences in the conidial fungi community between the dry and rainy periods. A high richness of leaf litter conidial fungal was uncovered in this area of humid forest surrounded by the semiarid vegetation of Caatinga.

Knowledge of the nutritional efficiency of species can help revegetation of forest areas, guiding the use of species that best adapt to environmental humidity, altitude and diversity. The objective of this study was to evaluate the nutrient utilization efficiency of N, P, K, Ca and Mg of dominant species in tropical dry forest and rainforest environments. The work was carried out in two areas, both in Pernambuco state, characterized as: Tropical Dry Forest of Caatinga and Tropical Rainforest of Atlantic Forest. A floristic and phytosociological survey was carried out. Species with highest density were evaluated, four from the dry forest and three from the rainforest. For each species, leaves of five healthy individuals of similar size were sampled and nutrient contents were determined. Leaf biomass was estimated by allometric equations. Rainforest species were more efficient in the use of N and K, and dry forest species in the use of P and K. In the dry forest environment, the species Pilocarpus spicatus and Guapira oposita stored more nutrients, and in the rainforest, the species Dialuim guianese was more efficient. These species are essential for the balance of ecosystems and the continuous and sustainable cycling of nutrients.
