It is important to know the growth rate of the species to be managed to establish sustainable forest management plans because from this information, it is possible to know which species have reached the minimum commercial size to be collected in future harvests. Manilkara elata (Allemão ex Miq.) Monach is considered one of the most commercialized timber tree species, both inside and outside of Brazil. Thus, the objective of this study was to model the growth rate and the time required for the trees of this species to reach the minimum cutting diameter defined by the current Brazilian legislation; the analysis was based on the adapted Weibull function with data from 31 years of monitoring in the National Forest of Brazil in Tapajós, Pará, Amazon, Brazil. Three models were proposed to estimate (i) the annual periodic increase in diameter (API), (ii) the future diameter (df) and (iii) the time period in years (t) that each tree would need to reach a future diameter according to the average growth rate of the target species and its forest community. Taken together, the data from the managed and unmanaged areas showed no statistically significant differences between the values observed and estimated by the proposed model when assessed with the Graybill F test. The adapted Weibull model performed well when estimating the annual periodic increment and future tree diameter of the M. elata population. Based on the diameter growth rate, the 5 cm diameter M. elata trees would require 601?781 years to reach the minimum commercial diameter of 50 cm, but the 40?49.9 cm diameter trees that are considered stock for the next harvest would take an average of 20 years to reach this commercial diameter. As the estimated average growth time is shorter than the cutting cycle prescribed by the legislation (25?35 years), it is recommended that forestry treatments that favor longer survival of M. elata individuals be adopted to achieve greater continuous production by primarily considering the long period that young individuals need to reach the cutting diameter.

A produção brasileira de leite de búfala e de seus derivados vêm crescendo anualmente devido às suas características peculiares. O gênero Staphylococcus destaca-se por ser causador da mastite contagiosa e de difícil tratamento devido à resistência aos antimicrobianos. Neste estudo foram colhidas 160 amostras de leite de búfala de uma propriedade localizada no município de Analândia, Estado de São Paulo. Nenhuma búfala apresentou sinais clínicos de mastite, 32 quartos mamários apresentaram mastite subclínica com reação positiva ao CMT. Foram isoladas 22 estirpes de Staphylococcus aureus (13,7%). As estirpes demonstraram sensibilidade à cloranfenicol (100%), rifampicina (100%), cefepime(100%), oxacilina(100%), ciprofloxacina, gentamicina(100%), tetraciclina (100%) clindamicina (96,9%), vancomicina (96,9%), (96,9%), cotrimoxazol (93,8%) e, entretanto demonstraram resistência à penicilina (31,3%) e eritromicina (43,8%) e uma estirpe apresentou-se multirresistente. Estes resultados reforçam que assim como nos bovinos, os bubalinos necessitam de um rígido programa de controle sanitário, principalmente da mastite. |
