Anthropogenic rapid warming has caused decreases in richness and body mass of birds following the metabolic theory of ecology; yet, the pervasiveness of these shifts remains controversial among different taxa. Here, by combining phylogenetic methods and fossil data, we synthesized spatial patterns of richness and body mass for 328 seabird species belonging to two groups: Procellariimorphae (PM) and non-Procellariimorphae (NPM). We found that the relationship between body mass and richness, as well as diversification rate, exhibits distinct patterns in these two groups.

Juniperus spp. are keystone shrubs in western North America and important climatic indicators in paleo-records. However, a lack of taxonomic resolution among fossil species limits our ability to track past environmental changes.

Detailed descriptions of the maxillae of Siamopithecus eocaenus, discovered from the latest Eocene/earliest Oligocene lignite mine in the Krabi basin of Peninsular Thailand, are presented. They include the morphology of P-M, the palate, a partial orbital region, and the zygomatic root. The specimen exhibits distinctive dental features including a single-rooted P alveolus, a protocone on the P and P, and a true hypocone on the upper molars, indicating its derived anthropoid dentition.

Most chelicerates operate the world with two kinds of visual organs, the median and lateral eyes of the arthropod ground plan. In harvestmen (Opiliones), however, members of the small and withdrawn suborder Cyphophthalmi lack eyes except for two genera with lateral eyes. In the other suborders (Eupnoi, Dyspnoi, and Laniatores), lateral eyes are absent but median eyes pronounced.
