“…Epidendrum and Catasetum present high numbers of species in the state (31 species each; Flora do Brasil 2020, continuously updated), being also among the most expressive genera in other municipalities and regions of Pará where floristic-taxonomic studies of Orchidaceae have been conducted (Cardoso et al 1995;Silveira et al 1995;Atzingen et al 1996;Koch et al 2014Koch et al , 2018Afonso et al 2016;Ferreira Filho et al 2021). Regarding the substrate, epiphytes were predominant in the present study and in the aforementioned studies.…”

“…Measurements and illustrations of vegetative and reproductive structures were made with the aid of a smartphone coupled to a stereomicroscope. Specific literature for the family was used for species identification, such as Hoehne (1949), Dunsterville & Garay (1979), Dressler (1981), Carnevali et al (2003), Silva & Silva (2011), Koch et al (2014), Afonso et al (2016) and Ferreira Filho et al (2021). Data referring to the distribution of epiphytic species in the phorophyte strata were provided when available.…”

The municipality of Igarapé-Miri is located in the Endemism Center of Belém, which corresponds to the most deforested portion of the Brazilian Amazon with only 38% of its native forest remaining. The family Orchidaceae has several endemic taxa and expressive diversity in the Amazon phytogeographic domain, including in the state of Pará where 97 genera and 395 species have been reported. Considering the advanced state of fragmentation and the loss of diversity in the region, together with the lack of information about the flora of the municipality of Igarapé-Miri (Pará, Brazil), a floristic-taxonomic study was undertaken of the species of Orchidaceae in the municipality, including an identification key, morphological descriptions, taxonomic comments, illustrations and information on habitat, phenology and the geographic distribution of species. Fifty-eight species distributed in 38 genera were recorded for the municipality of Igarapé-Miri. The most diverse genera were Epidendrum (7 spp.) and Catasetum (4 spp.), followed by Maxillaria, Scaphyglottis and Stelis (3 spp. each). Most species occur as epiphytes and in Terra Firme Forest, with 31 species being exclusive to this type of vegetation. The occurrence of Anathallis fastigiata, Catasetum albovirens, Dichaea brachyphylla and Palmorchis triquilhada, species restricted to the Brazilian Amazon, stands out. The distribution of Stelis palmeiraensis is expanded to the Amazon phytogeographic domain and Stelis ciliaris and Uleiorchis ulei are documented in the state of Pará for the first time.

“…The opening and maintenance of trails and the pruning of lower and weaker tree branches are anthropogenic disturbances that may have negatively affected the findings of our study in the Sapucaia Park. In addition, the vegetation of the park includes species with morphological characteristics that do not favor the establishment of epiphytes, as in the case of açaí palm trees that have smooth stipes and unbranched canopies [32] . The low abundance and specific richness of epiphytes found in this study may also be associated with the edge effect, which promotes unfavorable conditions for the occurrence of epiphytes such as higher luminosity and lower humidity [33] .…”

Vascular epiphytes are one of the most important forest components, contributing to microclimatic maintenance. These plants find ideal conditions for development in the Amazon due to the spatial heterogeneity and high temperature and humidity typical of this biome. In recent years, the Brazilian Amazon has undergone dramatic changes in its landscape, mainly due to the increase in deforestation and fire rates. We present here the floristic composition and analyze the community structure of epiphytic angiosperms of an urban forest fragment in Eastern Amazon. A total of 71 epiphytic individuals were recorded belonging to eight species and four families. Orchidaceae was the most representative family, corroborating the pattern for surveys of epiphytic diversity in the Neotropical region. Epiphytic species were found on 24 individuals of 10 tree species. The epiphytic importance value (IVe) was low for all species, except for Aechmea tocantina and Rhipsalis baccifera. Cactaceae was the family with the highest IVe. Most epiphytes were found in the crown of trees (83.1%). The diversity index of the fragment was H’ = 1.80 and the equity index was J= 0.87, reflecting the absence of highly dominant species. Conservation of urban forest fragments is necessary for the maintenance of epiphytic flora and ecosystem services.

“…In addition, the center of species diversity in Mexico is under intense anthropogenic pressure, and renewal of planted varieties is increasingly unlikely [ 6 ]. Many of vanilla’s suitable and/or native biomes are threatened and changes in tree species composition can bring irreparable damage to vanilla communities, as these semi-terrestrial orchids are found on shrubs and trees [ 15 ]. Furthermore, the agricultural production of vanilla occurs predominantly in only a few countries outside the Neotropics, the native growing area of aromatic vanilla [ 12 ].…”

Vanilla is a worldwide cherished condiment, and its volatile market is associated with the so-called “vanilla crisis”. Even though only two species (Vanilla planifolia and V. × tahitensis) are cultivated on a large scale for commercial purposes, the Vanilla genus is comprised of 140 species. The present review article discusses the facets of this crisis, and vanilla crop wild relatives (WRs) are showcased as alternatives to overcome them. Historical, taxonomic, and reproductive biology aspects of the group were covered. Emphasis was given to the metabolic characterization of the vanilla crop WRs, highlighting their main chemical classes and the potential flavor descriptors. Many of these species can produce important flavor compounds such as vanillin, vanillic acid, and acetovanillone, among others. Overall, this review compiles valuable information that can help unravel new chapters of the history of this treasured product by evidencing the biotechnological potential of vanilla crop WRs.
