The invasion process involves overcoming certain barriers with negative effects on the biodiversity and ecosystem function. This is the case of the African dung beetle Digitonthophagus gazella, which was introduced in the United States and other countries in Central and South America to help in dung removal activity. The distribution of D. gazella has been documented in the Americas, but in venezuela there is little information. Trying to understand the process of invasion of the Colombian-venezuelan savannas and measure their potential impact, the information stored in collections and literature was collected. Five new state records were reported for venezuela, as well as four scenarios of the process of introduction and establishment of this species in the region. Although the amount of records has increased, the number of individuals sampled is still incipient. The possible areas of invasion and the potential negative effects that the presence of this species exerts in these regions are also discussed. In addition, potential areas of invasion and negative effects of this species are discussed. Results emphasize the importance of generating models of the invasive process in order to design programs that monitor the effects incurred by the presence of D. gazella on native species and propose control and mitigation mechanisms.

Combined Radiometric Analysis Related to Guava Leaf Phenology in Response to Soil Application of Paclobutrazol (PBZ)

International Journal of Geosciences 2022年第8期13卷 681-694页

The leaf-response to three-soil applied treatments of Paclobutrazol (PBZ;1000, 2000 and 0 ppm-control) was studied in a high-density plantation of eight guava (Psidium guajava) genotypes trees. All materials were prunned in vase form, with two to three major branches, yearly prunning for triggering the annual production cycle, and average height of 2.0 m. The dataset comprises fourth radiometric indices highly related to plant physiological activities. The dataset model took into account data collection dates, guava genotypes, and the positional effect of sun radiation on leaves based on their proximity to the canopy level and downward to the base of the woody seasonal-branch. Unexpectedly, there were no significant differences (NS) in PBZ treatments for genotypes, leaf position and radiometric indices. Analysis of the radiometric indices data revealed that anthocyanin (ari index) and chlorophyll (PRI index) have a strong inverse relationship. Significant differences (P ≤ 0.05) were found between guava genotypes, and anthocyanin content;these results show that guava genotypes have varied responses, which could derive in their classification based-on drought resistance or low water requirements, however, it is important to note that additional research is required to determine the scope of these indications.

Braamcamp Freire中学位于里斯本庞蒂尼亚历史城区的边缘，占地约17380m^2，毗邻起伏的地势。除了学校北面的山谷，整个校园都是庞蒂尼亚城区的一部分。该校始建于1986年，由五栋标准化预制建筑组成——中间一栋为平层，另外四栋为二层建筑。这些建筑按照东西向排列，通过走廊相互连接。学校设施包括一个体育馆和一个地势较低的户外操场，两者与教学楼都没有连接。
