Although the ecological network approach has substantially contributed to the study of plant-pollinator interactions, current understanding of their functional structure is biased towards diurnal pollinators. Nocturnal pollinators have been systematically ignored despite the publication of several studies that have tried to alleviate this diurnal bias. Here, we explored whether adding this neglected group of pollinators had a relevant effect on the overall architecture of three high mountain plant-pollinator networks. Including nocturnal moth pollinators modified network properties by decreasing total connectivity, connectance, nestedness and robustness to plant extinction; and increasing web asymmetry and modularity. Nocturnal moths were not preferentially connected to the most linked plants of the networks, and they were grouped into a specific “night” module in only one of the three networks. Our results indicate that ignoring the nocturnal component of plant-pollinator networks may cause changes in network properties different from those expected from random undersampling of diurnal pollinators. Consequently, the neglect of nocturnal interactions may provide a distorted view of the structure of plant-pollinator networks with relevant implications for conservation assessments.

El presente trabajo describe la mirada estética de la película Roma (2018), de Alfonso Cuarón, la cual se genera a partir del movimiento de la cámara en planos generales largos y desplazamientos horizontales. Se analiza la trama que se desprende de las secuencias y, en función de esta trama y el mundo que representa, se considera la caracterización de los personajes a partir de su posicionamiento en relación con determinados parámetros convencionales de clase, etnia y género del sistema social que la película refleja; particularmente, a partir del personaje de la criada Cleo., This work describes the aesthetic perspective of the film Roma (2018), directed by Alfonso Cuarón, which is generated from the movement of the camera in long wide shots with panning. We analyse the plot that arises from these sequences, and based on the plot and the world portrayed, we consider the characters in relation to conventional parameters of class, ethnicity, and gender in the social system reflected in the film, particularly through the maid Cleo.

Variation in species richness across the tree of life, accompanied by the incredible variety of ecological and morphological characteristics found in nature, has inspired many studies to link traits with species diversification. Angiosperms are a highly diverse group that has fundamentally shaped life on earth since the Cretaceous, and illustrate how species diversification affects ecosystem functioning. Numerous traits and processes have been linked to differences in species richness within this group, but we know little about their relative importance and how they interact. Here, we synthesised data from 152 studies that used state-dependent speciation and extinction (SSE) models on angiosperm clades. Intrinsic traits related to reproduction and morphology were often linked to diversification but a set of universal drivers did not emerge as traits did not have consistent effects across clades. Importantly, SSE model results were correlated to data set properties - trees that were larger, older or less well-sampled tended to yield trait-dependent outcomes. We compared these properties to recommendations for SSE model use and provide a set of best practices to follow when designing studies and reporting results. Finally, we argue that SSE model inferences should be considered in a larger context incorporating species' ecology, demography and genetics.
