Hierarchical Modelling of Aquatic Species Distributions

Global Ecology and Biogeography, Volume 35, Issue 9, September 2026.
ABSTRACT Aim Species Distribution Models (SDMs) have traditionally been developed in a terrestrial context, and their application to aquatic ecosystems presents unique challenges. These include predicting species distributions across spatially constrained environments and incorporating environmental drivers that operate across nested spatial scales. We

Ichthyofauna sampled with tadpoles in northeastern Maranhão state, Brazil [PDF]

, 2015
The Neotropic region has high fish diversity associated with freshwater habitats. However, for Maranhão state, most publications on the ichthyofauna concentrate on coastal or estuarine ecosystems. In this study, species of fish were sampled in lentic and

Phylogeographic Patterns of the Eigenmannia humboldtii Group Shaped by Miocene‐Pleistocene Transitions

Journal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim Eigenmannia is a monophyletic genus of small and medium‐sized fishes known as ‘glass knifefishes’, with a wide distribution throughout the Neotropical region and a complex taxonomic history. This study aimed to investigate the phylogenetic diversification patterns within the Eigenmannia humboldtii species group (specifically E. nigra and E.

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA

Journal of Fish Biology, Volume 109, Issue 3, Page 1771-1785, September 2026.
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present

Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters

Global Change Biology, Volume 32, Issue 8, August 2026.
Polar sharks, rays, and chimaeras face growing pressures from changing sea‐ice conditions, expanding fisheries, and limited protection. Our assessment highlights where critical habitats occur and how Important Shark and Ray Areas (ISRAs) can support more targeted conservation and fisheries management across the Arctic and Antarctic.

Notes on a remotely operated vehicle survey to describe reef ichthyofauna and habitats – Agulhas Bank, South Africa

Bothalia: African Biodiversity & Conservation, 2016
Background: Despite their ecological and economic importance, reef habitats on the central Agulhas Bank, off the southern tip of Africa, remain poorly studied. The ichthyofauna of these habitats cannot be surveyed using trawl gear. Objective: Preliminary
