The intestine as a diagnostic character in identifying certain clupeoids (Engraulididae, Clupeidae, Dussumieriidae) and as a morphometric character for comparing anchoveta (Centengraulis mysticetus) populations [PDF]

open access: yes, 1958
ENGLISH: The several species of clupeoid fishes used as baitfish in the Eastern Pacific tuna fishery are, in some cases, sufficiently similar to make identification difficult.

Limited complementarity of functional and taxonomic diversity in Chilean benthic marine invertebrates

open access: yesDiversity and Distributions, Volume 30, Issue 6, June 2024.
Abstract Aim Patterns of benthic biodiversity at the macroecological scale remain poorly characterised throughout the Chilean latitudinal gradient, in part due to the lack of integrated databases, uneven sampling effort, and the use of species richness alone to quantify biodiversity.

Metabolism, population growth, and the fast‐slow life history continuum of marine fishes

open access: yesFish and Fisheries, Volume 25, Issue 2, Page 349-361, March 2024.
Abstract The maximum intrinsic rate of population increase (rmax) represents a population's maximum capacity to replace itself and is central to fisheries management and conservation. Species with lower rmax typically have slower life histories compared to species with faster life histories and higher rmax. Here, we posit that metabolic rate is related

Functional Convergence and Taxonomic Divergence in the Anchoveta (Engraulis ringens) Microbiome

open access: yesFishes
Gut microbial community assembly involves a critical bioenergetic trade-off, yet the gut microbes with roles in influencing intestinal metabolic homeostasis remain poorly understood in pelagic ecosystems.
