One of the main barriers to restoration is the arrival of diaspores in degraded areas. However, this process can be hampered in open areas without trees in the landscape. For that, artificial perches are used to attract and provide a landing area for avian seed dispersers, to enhance seed rain. Our objective was to evaluate the effect of the distance of artificial perches in relation to a forest fragment on the diversity and composition of seed rain in an agricultural fallow area, including alien invasive plant species. We also aimed to record and characterize the bird species that potentially act as seed dispersers. Thus, we used artificial perches at three different distances from a forest fragment (5, 25, and 50 m). Four seed traps were arranged under the perches at each distance, and four control seed traps were interspersed with these and distanced at 7.5 m. Furthermore, we placed four seed traps inside the forest fragment at 5m from the edge.We also carried out 80 h of focal observation of the avifauna that used artificial perches. A total of 24 655 seeds were sampled across all treatments. There was a significant difference in seed abundance and richness between artificial perches, control seed traps, and forest seed traps. Seed deposition increased with distance from the forest fragment (50, 25, and 5 m). An ordination procedure indicated the formation of three plant seed communities, with the forest community being most distinct. The invasive exotic species Pittosporum undulatum (Australian cheesewood) was the third most abundant in the seed rain. We observed 24 bird species from 12 families using artificial perches. The Tyrannidae family was the most represented. We showed that artificial perches are efficient structures for attracting birds, increasing the richness and abundance of seed species. Artificial perches at 25 and 50m were more efficient possibly due to the provision of greater visibility for birds. Therefore, artificial perches are efficient in increasing seed rain in the fallow area but should be used with caution in landscapes with the presence of alien species. These findings contribute to increasing knowledge about overcoming the first barrier to ecological restoration, which is the arrival of diaspores in degraded areas, and showing the importance of birds in this process.

Abstract: This study evaluated the effect of different cutting intensities and years of harvesting on the morphological characteristics and production of fresh (FMP) and dry matter (DMP) of cactus pear cv. Gigante (Opuntia ficus-indica Mill) under conditions of irrigation, high planting density and fertilization, with 12 months of regrowth. The experimental was completely randomized in a factorial design (3 × 2) with 12 replicates. The treatments were three cutting intensities (preserving the mother cladode (PMC), primary cladodes (PPC), or secondary cladodes (PSC)), and two years of harvesting. The soil was classified as Cambisol Haplicum and the irrigation water was classified as C4S1 (EC 5.25 dS.m-1) density of 50,000 plants ha-1. The research evaluated plant height, number of cladodes per plant (NCP), length, width, perimeter and thickness of the cladodes, cladode area (CA), cladode area index (CAI), FMP and DMP. There was no significant interaction between treatments (P > 0.05) for the variables plant height, NCP, CAI and FMP. The variables related to cladode morphology showed a significant interaction (P < 0.05). The treatment PSC resulted in a greater DMP (P < 0.05) with a mean of 27.17 Mg ha-1 yr-1, compared to PPC (18.58 Mg ha-1 yr-1) or PMC (11.78 Mg ha-1 yr-1). The treatment PSC promoted greater NCP and forage productivity at harvest and can be considered as a management practice for the sustainability of cactus pear cv. Gigante under irrigation. The more important morphological characteristics were also influenced by the lower cutting intensities.

Resumo: A pesquisa objetivou avaliar o efeito de diferentes intensidades de corte e anos de colheita, sobre características morfológicas e produções de matéria verde (PMV) e seca (PMS) da palma forrageira cv.

O delineamento experimental foi inteiramente casualizado em esquema fatorial (3 x 2) com 12 repetições. Os tratamentos constaram de três intensidades de corte (preservando o cladódio mãe (PCM), os cladódios primários (PCP) e os secundários (PCS) e dois anos de colheita. Período experimental 24 meses e duas colheitas com intervalos de 12 meses. O solo foi classificado como Cambissolo Háplico e a água de irrigação C4S1 (CE 5,25 dS.m-1) e densidade de 50.000 plantas ha-1. Foram avaliados: altura e número de cladódios por planta (NCP), comprimento, largura, perímetro, espessura e área dos cladódios (AC), índice de área dos cladódios (IAC), PMV e PMS. Não foi observada interação significativa (P>0,05) dos tratamentos para as variáveis altura, NCP, IAC e PMV. Variáveis relacionadas à morfologia dos cladódios apresentaram interação significativa (P<0,05). O tratamento PCS resultou na maior PMS (P<0,05) com produtividade média de 27,2 Mg ha-1 ano-1, quando comparada à PCP (18,6 Mg ha-1 ano-1) ou PCM (11,8 Mg ha-1 ano-1). O tratamento PCS no momento da colheita promoveu maior NCP e maior produtividade de forragem, sendo uma alternativa de manejo com vistas à sustentabilidade da palma cv. Gigante sob irrigação. As características morfológicas mais importantes também foram influenciadas pelas menores intensidades de corte.
