“…hosts with peeling bark are also colonized by atmospheric bromeliads, which are also distributed toward the smaller branches (López‐Villalobos et al, 2008; Ruiz‐Cordova, Toledo‐Hernández, & Flores‐Palacios, 2014), where the microenvironments not only explain the vertical distribution of epiphytes, but also the seed entrapment area and the diminished peeling rate. Our results coincide with the atmospheric epiphytic Tillandsia with plumose seeds such as T. bandensis , T. duratii , T. meridionalis , T. loliaceae , T. recurvata , and T. tricholepis , which also colonize the thinnest branches in the top of the crown, but on different hosts, in a xerophytic forest in Argentina (Alvarez‐Arensi, Barberis, & Vesprini, 2018), in a woodland savanna forest in Brazil (Joanitti, de Lara Weiser, Cavassan, & Giles, 2017), and in the tropical dry forests in Mexico (García‐Suárez et al, 2003; Ruiz‐Cordova et al, 2014). These Tillandsia spp.…”

Host traits partly determine the abundance and species richness of epiphytes in tropical forests. It has been proposed that older trees with rough bark and evergreens often house more individuals and more epiphytic species than those with thin, smooth, and peeling bark, which harbor few epiphytes. We hypothesize (i) that epiphytes are more abundant and species‐rich in the more shaded forest, which is related to bark roughness, and (ii) that epiphytes are distributed in the middle of the host, where microenvironmental conditions are more favorable to survival. We evaluated abundance, species richness, and vertical distribution of epiphytes in two tropical dry forests, according to the deciduousness and basal area of the trees. Moreover, we selected the most abundant epiphytes to test whether their distribution is related to a specific bark type and examine their vertical distribution in two dry forests. We distinguished a high abundance and species richness of epiphytes in the deciduous forest, although basal area and host species richness were higher in the semi‐deciduous forest. In both forests, we found a positive relationship between epiphyte abundance and basal area. Higher abundance of epiphytes was related to the predominance of Tillandsia schiedeana, a drought‐adapted species, in both forests. Unexpectedly, epiphytes abundantly colonized Bursera simaruba, a host with peeling bark and a very branched crown, where small individuals of T. schiedeana colonized abundantly toward the top of the crown. Our results show the importance of the tropical dry forest, particularly, B. simaruba, in maintaining epiphyte diversity in terms of T. schiedeana colonization.

“…En menor grado se presentó en Ligustrum lucidum y Casuarina equisetifolia (cinco árboles). Las características anatómicas del tronco y ramas (por ejemplo, relieve, diámetro, tamaño y edad, presencia de espinas y otras estructuras) se encuentran entre los principales factores que determinan el establecimiento exitoso de T. recurvata (Álvarez et al, 2018;Benzing, 1990;Bernal et al, 2005;Caldiz et al, 1993;Harvey, 1996;Hietz y Hietz-Seifert, 1995b). Aunque, una selección debida a la textura de la corteza o su composición química puede no hacer la diferencia, según Kernan y Fowler (1995).…”

The “ball moss” or “paxtle” (Tillandsia recurvata L.) is one of the main health problems in the trees of the National Instituteof Astrophysics, Optics and Electronics (INAOE). With the present survey, host preference, level of infestation, mainphenological stages, and control options of the epiphyte were determined. From the tree inventory, the species and theirdimensions (normal diameter and total height) were identified, the level of infestation by “paxtle” was determined and themain phenological stages of the epiphyte were recorded. The effectiveness of sodium bicarbonate spraying for control wasevaluated. Of 2210 trees, 37.23% were infested. Jacaranda (Jacaranda mimosifolia), ash (Fraxinus uhdei), white cedar(Hesperocyparis lusitanica) and glossy privet (Ligustrum japonicum) showed the largest infestations. No specificity wasobserved. The normal diameter was associated with the level of infestation. Seed dispersal occurred from January to April.The application of sodium bicarbonate caused dehydration, necrosis and death of the epiphyte. T. recurvata has become aserious health problem in the green areas of the INAOE. It is recommended to implement control activities in the months ofOctober and November (prior to the dehiscence of the capsules and in the absence of foliage in deciduous tree species).

“…In the Amazonian domain, characterized by evergreen tropical and subtropical forests with high precipitation, it mainly grows as epiphytic. In the Chaquenian domain, dominated by xerophytic forests with low rainfall, high soil pH, and base saturation, it mainly grows as terrestrial, whereas in the Seasonally Dry Tropical Forest domain, the three life forms were recorded in similar proportions (Alvarez Arnesi, Barberis and Vesprini 2018; Barberis et al 2021).…”

The Bromeliaceae are known for providing numerous ecosystem services. Tank bromeliads that collect water in the bases of their leaves have been an important source of water for people in semiarid regions such as the Gran Chaco. In this large area characterized by xerophytic vegetation grows Aechmea distichantha, the only Chaquenian terrestrial tank bromeliad. We carried out a literature review on water consumption from this tank bromeliad by people in this region. Then, we analyzed the variations in the amount of water stored in the tanks of plants from observational studies as well as the effects of the amount and frequency of water addition on the hydrology of water retained in the tank from an irrigation experiment study. We found 85 reports on the consumption of water from A. distichantha plants by people, including several Indigenous Groups, Criollos, and Soldiers. According to these reports, the tank accumulates about a liter of relatively fresh and clear water that lasts for several weeks. Our observational study showed a large variation in the amount of water held in the tank among years and sites, and our irrigation experiment showed that even plants receiving low and unevenly distributed rainfall conserved some water in their tanks. All these results support the importance of this tank bromeliad for surviving when moving in Eastern Chaco during dry periods until the beginning of the twentieth century. At present, it seems that people living in sedentarism no longer frequently use it for water provision, highlighting that the relative importance of a plant species for providing ecosystem services depends on the historical context.
