“…These indicate that there might be an opposite triangle relationship among seedling survival, soil environmental factors, and soil fungi [19]. In the place close to adult conspecifics, the "fertile island effect" leads to favorable soil environmental conditions in this site (such as a higher nutrient content and higher water content) [20,21]. At the same time, the closer distance results in a higher density of parasitic fungi from the adults [9,11].…”

“…The advantages of these two aspects would make it easier for harmful parasitic fungi to infect seedlings and inhibit seed germination, thus increasing seedling mortality and altering the distribution pattern of seedling density [9,11,21]. Here, the "island of fertility" is the phenomenon where trees act as a nutrient pump, taking up nutrients from deep soil layers and soil outside the single tree's canopy, and depositing the nutrients back under the tree canopy through litter fall or leaching [20,57]. On the contrary, a reduction in the influence of the "island of fertility" on nutrient enrichment causes the relatively low soil nutrient contents in places far from the adults [20,21].…”

“…The relationship between soil fungi and seedling density also may be affected by environmental factors [12,[19][20][21] (see the conceptual framework in Figure 1). For example, environmental factors can influence the abundance of a soil fungus in a forest community, which may in turn the affect seedling density by reducing the resistance of the plants to the fungus (Figure 1).…”

Research Highlights: 1. Soil fungi have a higher influence on seedling density compared to soil environmental factors; 2. Host-specific pathogens and beneficial fungi affect seeding density via different influencing mechanisms. Background and Objectives: The growth and development of seedlings are the key processes that affect forest regeneration and maintain community dynamics. However, the influencing factors of seedling growth around their adult conspecifics are not clear in arid desert forests. Probing the intrinsic relations among soil fungi, soil environmental factors (pH, water content, salinity, and nutrition), and seedling density will improve our understanding of forest development and provide a theoretical basis for forest management and protection. Materials and Methods: Four experimental plot types, depending on the distance to adult conspecifics, were set in an arid desert forest. Soil environmental factors, the diversity and composition of the soil fungal community, and the seedlings’ density and height were measured in the four experimental plot types, and their mutual relations were analyzed. Results: Seedling density as well as the diversity and composition of the soil fungal community varied significantly among the four plot types (p < 0.05). Soil environmental factors, especially soil salinity, pH, and soil water content, had significant influences on the seedling density and diversity and composition of the soil fungal community. The contribution of soil fungi (72.61%) to the variation in seedling density was much higher than the soil environmental factors (27.39%). The contribution of detrimental fungi to the variation in seedling density was higher than the beneficial fungi. Conclusions: Soil fungi mostly affected the distribution of seedling density in the vicinity of adult conspecifics in an arid desert forest. The distribution of seedling density in the vicinity of adults was mainly influenced by the detrimental fungi, while the adults in the periphery area was mainly influenced by the beneficial fungi.

“…These species are commonly denominated as ''Mesquite'' in USA and "Mezquite" in Mexico (Rzedowski 1988), and they are known for being drought tolerant (Nilsen et al 1983). They are also important for reducing soil erosion, fix nitrogen and improve soil fertility in arid and semiarid zones (Tiedemann and Klemmedson 1973;Salazar et al 2019). Mesquites also provide food for many wild and domestic animals which feed on their nectar, pollen, leaves and pods (Ruiz-Nieto et al In press).…”

Key message The epiphyte Tillandsia recurvata modifies the anatomy of the xylem, phloem and periderm of its host Prosopis laevigata, these modifications affect water flux and photosynthetic activity in this host. Abstract The relationships between epiphytes and host plants are commensal interactions, where epiphytes obtain support to growth without damaging their hosts. However, some epiphytes may cause the death of branches in their hosts. Ball moss (Tillandsia recurvata) is an epiphyte with elevated reproductive success in semiarid zones of México, growing mainly on mesquite trees (Prosopis laevigata). Mesquites are of great ecological and economical importance in central and northern Mexico, but the elevated mortality of branches and even whole trees have been associated with high ball moss loads. This study evaluates whether ball moss causes structural damage in the phloem, xylem, and periderm of mesquite branches, also testing whether the physiological performance of these branches was reduced. For this we measure the effective quantum yield of photosystem II (Φ PSII), hydraulic conductivity, water flux, number of vessels and the effective area of conduction in mesquite branches with and without ball moss. The results demonstrated that juvenile ball moss only affected the periderm and the collapsed phloem with no damage to non-collapsed phloem or xylem, but the reproductive individuals modified the anatomy of the xylem, phloem and periderm of mesquite. These structural modifications affected both water flux and hydraulic conductivity and reduced the Φ PSII. Our findings suggest that structural and ecophysiological changes induced by the ball moss are the cause of high branch mortality in mesquite. This is the first study showing anatomical and ecophysiological evidence of an epiphytic plant damaging its host.
