Predicting the impacts of palmheart and fruit harvesting using integral projection models10/20/2022 In Mendes et al. 2022, the authors assess how the harvesting of non-timber forest products (NTFP) in palms (i.e. palmheart and fruit harvesting) can affect demographic processes of the palm Euterpe edulis in its native range in the Atlantic Forest in Brazil. Their results show that palmito populations are somewhat tolerant to fruit harvesting, but because populations are already at reduced sizes, palmheart and extensive fruit extraction can affect population persistence.

In de Lima et al. 2022, published on Frontiers in Forests and Global Change, Thales and colleagues use species distribution modeling to better understand the distribution of palm richness in Rio de Janeiro state, Brazil, in order to identify priority areas for palm conservation in the state. Some of the palms studied: Allagoptera arenaria, Allagoptera caudescens, Astrocaryum aculeatissimum, Attalea dubia, Attalea humilis, Bactris caryotifolia, Bactris setosa, Bactris vulgaris, Euterpe edulis, Geonoma elegans, Geonoma pohliana, Geonoma schottiana, Syagrus picrophylla, Syagrus pseudococos and Syagrus romanzoffiana.

Please check out the special issue on Functional Ecology and Conservation of Palms, which has been published in Frontiers in Forests and Global Change. All articles can be accessed here. Fantastic editorial work done by the colleagues Gerardo Avalos, Thaise Emilio, Kelly M. Andersen and Silvia Alvarez-Clare! Posted by Caroline Dracxler
In Ávila et al. 2022, published in the Acta Botanica Brasilica, the authors describe phenological patterns of Mauritiella armata palms and their response to environmental filters (e.g. temperature, total precipitation, air humidity). Their results show that reproductive phenophases responded mainly to the temperature observed in the period preceding the phenophase, but also to environmental variations that had occurred up to six months earlier. Besides, authors observed no dispersal of pollen by wind, which indicates that this palm species requires biotic pollination for fruit production! Posted by Caroline Dracxler
In Salvador et al 2022 published in Forest Ecology and Management, the authors show that, despite having recalcitrant seeds, the palm Mauritia flexuosa can form persistent soil seed banks in humid environments such as the veredas found in northern Minas Gerais State, Brazil!

In Avalos et al. 2022, published in Frontiers in Forests and Global Change, Gerardo Avalos and colleagues present allometric models for estimating total carbon content and above ground carbon (AGC) using seven abundant neotropical palm species (Socratea exorrhiza, Iriartea deltoidea, Euterpe precatoria, Asterogyne martiana, Prestoea decurrens, Geonoma interrupta and Chamaedorea tepejilote).

In Stropp et al 2022 published in the commentary section of the Journal of Biogeography, the authors comment on how taxonomic history and unevenness could bias plant richness estimations using taxonomic changes in palms to illustrate it. Posted by Caroline Dracxler
Canopy palm cover across the Brazilian Amazon forests mapped with LIDAR data and deep learning10/19/2022 In Dalagnol et al 2022 published in Remote Sensing in Ecology and Conservation, the authors combined LiDAR flights with deep-learning to automatically map the canopy of >1 million palms in the Amazon in near 500 thousand hectares of forest. This novel remote sensing application could be the baseline for future vegetation mapping and forest dynamics monitoring. Posted by Caroline Dracxler
This paper, written by Caroline Dracxler and Daniel Kissling, results from a comprehensive compilation of interaction records among palms and frugivores along the Americas. In their research they show how interaction outcomes fall along a continuum between mutualism and antagonism, highlighting that most animal species can act as both mutualists and antagonists. The authors have also made available the full interaction dataset! Check out this open access paper on Biological Reviews! (here you can explore the interaction compilation) Posted by Caroline Dracxler
This paper, led by Thaise Emilio and Bob Muscarella (and many other researchers), reveals global patterns of palm abundance. One of the most interesting findings is that although palms can be found pretty much everywhere in tropical and subtropical parts of the globe, they are "overwhelmingly Neotropical"!
