Historical warming consistently decreased size, dispersal and speciation rate of fish

Jorge Avaria-Llautureo, Chris Venditti, Marcelo Rivadeneira, Oscar Inostroza-Michael, Reinaldo Rivera, Cristián Hernández & Cristian Canales-Aguirre
There is ongoing debate as to whether fish body size will decrease with global warming and how these changes may impact dispersal ability and speciation rate. Theory predicts that, under warmer temperatures, fish grow to a smaller size, undergo a reduction in dispersal ability and increase speciation rates. However, evaluations of such predictions are hampered owing to the lack of empirical data spanning both wide temporal and geographical scales. Here, using phylogenetic methods, we show...

Data from: Ontogenetic shape trajectory of Trichomycterus areolatus varies in response to water velocity environment

Peter Searle, Margaret Mercer, Evelyn Habit & Mark Belk
Body and head shape among fishes both vary between environments influenced by water velocity and across ontogeny. Although the shape changes associated with variation in average water velocity and ontogeny are well documented, few studies have tested for the interaction between these two variables (i.e., does ontogenetic shape variation differ between velocity environments). We use geometric morphometrics to characterize shape differences in Trichomycterus areolatus, a freshwater catfish found in high and low-velocity environments in Chile....

Species abundance along the railway of Kashmir Himalaya

Irfan Rashid, Marifatul Shiekh, Jonas Lembrechts, Anzar Khuroo, Anibal Pauchard & Jeffrey Dukes
1. The significant portion of global terrestrial biodiversity harbored in mountains is under increasing threat from a variety of anthropogenic impacts. Protecting fragile mountain ecosystems requires understanding how these human disturbances affect biodiversity. As roads and railways are extended further into mountain ecosystems, understanding the long-term impacts of this infrastructure on community composition and diversity gains urgency. 2. We used railway corridors constructed across the mountainous landscapes of the Kashmir Himalaya from 1994-2013 to study...

Neutral and adaptive loci reveal fine-scale population structure in Eleginops maclovinus from North Patagonia

Cristian B. Canales-Aguirre, Wesley A. Larson, Garret J. McKinney, C. Eliza Claure, J. Dellis Rocha, Santiago G. Ceballos, Maria I. Cádiz, José M. Yáñez & Daniel Gómez-Uchida
Patagonia is an understudied area, especially when it comes to population genomic studies with relevance to fishery management. However, the dynamic and heterogeneous landscape in this area can harbor important but cryptic genetic population structure. Once such information is revealed, it can be integrated into the management of infrequently investigated species. Eleginops maclovinus is a protandrous hermaphrodite species with economic importance for local communities that is currently managed as a single genetic unit. In this...

Data from: Putting vascular epiphytes on the traits map

Peter Hietz, Katrin Wagner, Flavio Nunes Ramos, Juliano Sarmento Cabral, Gerhard Zotz, Claudia Agudelo, Ana Maria Benavides, Manuel Cach Pérez, Catherine Cardelús, Nahelli Chilpa Galván, Lucas Costa, Rodolfo De Paula Oliveiras, Helena Einzmann, Rafael Farias, Valeria Guzmán Jacob, Michael Kessler, Catherine Kirby, Holger Kreft, Thorsten Krömer, Jamie Males, Samuel Monsalve Correa, Maria Moreno, Gunnar Petter, Casandra Reyes, Alfredo Saldaña … & Carrie Woods
Epiphyte trait data for the paper Hietz et al. 2021 Putting vascular epiphytes on the traits map. Journal of Ecology Plant functional traits impact the fitness and environmental niche of plants. Major plant functional types have been characterized by their trait spectrum, and the environmental and phylogenetic imprints on traits have advanced several ecological fields. Yet very few trait data on epiphytes, which represent almost 10% of vascular plants, are available. We collated >80,000 mostly...
