“…The results of this study may have significant implications for forest conservation and reforestation. Seed dispersal is essential for the regeneration of many tree species (Zhu et al ., 2014; Rader & Schneider, 2022). However, due to accelerated disturbance by humans, seed abundance is greatly reduced, whereas rodent abundance is increased (Yang et al ., 2022a), which often fails seed regeneration due to over‐predation of seeds by rodents.…”

Summary The interaction between animals and plants for seed dispersal and predation has received much attention; however, the underlying physiological mechanisms driving the responses of both seeds and animals remain unclear. We conducted a series of behaviour and physiology experiments to examine the role of plant hormones in regulating seed germination and rodent hoarding behaviour in the Quercus variabilis and Leopoldamys edwardsi systems. We found that acorns that were partially consumed by rodents had increased gibberellin (GA) levels and shortened germination time. Rodents preferred scatter‐hoarded abscisic acid (ABA)‐treated and intact acorns but consumed germinated and GA‐treated acorns; such treatment differences disappeared for inactivated acorns by boiling water. Moreover, we found that seven potential compounds may be linked to seed germination and rodent hoarding behaviour. Our results indicate that acorns of oak showed rapid germination when facing predation risk, while rodents could identify the germination status of seeds for hoarding; GA and ABA may play an important role in regulating seed germination of oak and hoarding behaviour of rodents.

“…This distinction is taken up in agrarian policy to justify converting secondary forest ecosystems to various land uses for capital accumulation (Liverman and Vilas, 2006; Pain et al 2021). However, forest recovery research across the global south has noted the biophysical contributions of regenerated forests, effectively challenging the notion of ecological degradation (Chazdon 2014;Poorter et al 2016), and recognizing the diverse forms regenerated forests can take (Chazdon et al 2006;Chazdon et al 2010, Rader andSchneider 2022).…”

Mexico’s neoliberal agrarian policies incentivize intensification, privatization, and field rotation regulations, often by stating that these practices conserve forest from inefficient land use. In Mexico’s Mesoamerican Biological Corridor, this policy discourse is interpreted by smallholders and preconditions land use decisions and subsequent local agriculture and forest cover configurations. Examining how discourses align with the reality of local land use and resulting agriculture-forest configurations is critical to understand the socio-ecological tradeoffs of implementing policies in local forests. We examine how one community’s understanding of land use and forest cover tradeoffs relate to the discourse of Mexico’s latest agrarian policy, Sembrando Vida (SV), using in-depth discourse network analysis. We show that while smallholders participate in multiple governmental programs, they interpret program policies based on their own independent land use histories and experiences. We shed light on how misalignments between policy aims, conservation discourses, and smallholder interpretations have material impacts on tropical forests.

“…The main purpose of this work was isolate and characterize a native strain of fungus, Phlebia floridensis , in the Yucatan Peninsula. The selected region (Tizimin, Yucatan) has a long history of climatic and deforestation disturbances, despite this there is no evidence of major floristic change over the past 6000 years supporting the idea of a relatively resilient biota [13, 14]. We hypothesized that valuable species of white rot fungi play a relevant role in the efficient recovery rate of carbon, caused by the organic degradation of lignin, in this region of the Yucatan Peninsula.…”

Phlebia genus is a relevant group of fungi with a crucial role in numerous ecosystems. In tropical and subtropical areas this genus allows the efficient degradation of lignin and carbon recovery; however, the majority of these fungal species remain undiscovered. The main purpose of this work was to determine the enzymatic activity of extracellular proteins of a novel Phlebia floridensis strain isolated in Yucatan Peninsula, Mexico. The results that are reported here demonstrate that the soluble protein extract of P. floridensis can degrade a broad spectrum of recalcitrant compounds. This induced protein extract is able to modify not only phenolic and nonphenolic compounds, but also anthroquinone dyes, even without the addition of exogenous hydrogen peroxide. Using liquid chromatography–mass spectrometry (LC‐MS), we were able to identify a novel chloroperoxidase in enzymatic extract. As far as we know, this is the first report about the presence of this type of enzyme in the Phlebia genus.
