“…It commonly grows with trees of the genera Escallonia , Gynoxys , Hesperomeles and Clethra ( Valenzuela and Villalba 2015 ). Growth of this species is most strongly correlated to growth season temperature ( Requena-Rojas et al 2020a , 2020b ). Polylepis rodolfovasquezii remnants harbor several threatened bird species, including Anairetes alpinus ( Quispe-Melgar et al 2018 , 2020 ).…”

We present a monograph of the high Andean tree genus Polylepis (Rosaceae), based on a species concept considering morphological, climatic and biogeographic distinctness as indicators of evolutionary independence. In total, we recognize 45 species of Polylepis, grouped in five sections. Polylepis sect. Sericeae is represented by 15 species in four subsections, P. sect. Reticulatae by seven species, P. sect. Subsericantes by three species, P. sect. Australes by two species and P. sect. Incanaee by three subsections with 18 species. We describe seven new species, one from Colombia (P. frontinensis), one from Ecuador (P. simpsoniae) and five from Peru (P. acomayensis, P. fjeldsaoi, P. occidentalis, P. pilosissima and P. sacra). Three species from Peru (P. albicans, P. pallidistigma and P. serrata) are re-instated as valid species. Two taxa from Bolivia (P. incanoides and P. nana) are elevated from subspecies to species rank. The morphology, habitat, distribution, ecology and conservation status of each species are documented. We also provide an identification key to the species of the genus and general introductions on taxonomic history, morphology, evolution, ecology and conservation.

Understanding what drives the evolution of nectar‐robbing strategies is key for gaining insight into the functioning of pollination networks. However, nectar robbing is often an anecdotal behaviour, difficult to quantify and record through field observations, especially in hummingbirds, limiting our understanding of how ecological networks change across communities. Here, we report new records of nectar robbing by Peru's endemic Black Metaltail (Metallura phoebe) in a high‐elevation forest at ca. 4000 m a.s.l. and how this species uses either legitimate pollination feeding or nectar robbing in relation to corolla lengths. Furthermore, by analysing 452 citizen science records of photographic observations, we found that 36% of the photographs depicting a foraging event in this species were actually nectar‐robbing events. After identifying the plant species in all photographs involving foraging events, we describe how nectar robbing conducted by this hummingbird species is strongly associated with flowers that have longer corollas. We propose that the hummingbird‐flower interactions in harsh high‐altitude environments, where resources and competition vary markedly across seasons, can offer insight into the ecological drivers of nectar‐robbing behaviour in hummingbirds.
