Early evolution of the gular musculature and its innervation in ray‐finned fishes

The Anatomical Record, EarlyView.
Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Evaluating the Air Respiratory Capacity of Awaous (Chonophorus) tajasica (Gobiiformes: Oxudercidae): A Morpho‐Functional Study

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
We demonstrated that Awaous tajasica performs facultative air breathing under experimental conditions of dissolved oxygen limitation, retaining air bubbles in the buccal cavity during gill ventilation. Morpho‐functional evidence indicates the use of atmospheric oxygen as a respiratory support under conditions of low water oxygenation.

Long photoperiod impairs learning in male but not female medaka

iScience, 2021
Summary: Day length in conjunction with seasonal cycles affects many aspects of animal biology. We have studied photoperiod-dependent alterations of complex behavior in the teleost, medaka (Oryzias latipes), a photoperiodic breeder, in a learning ...

Capacity building needed to reap the benefits of access to biodiversity collections

PLANTS, PEOPLE, PLANET, EarlyView.
Global conservation efforts increasingly depend on digitised natural history collections, yet the benefits of this digital data are not equally shared. We analysed biodiversity specimens and citation data from Montserrat and the Cayman Islands to assess who collected these specimens, how they are used, and by whom.

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—

Biodiversity, Systematics, and Taxonomy of Ostariophysi (Osteichthyes, Actinopterygii): What We Know Today After Three Decades of Integration of Morphological and Molecular Data

Taxonomy
Ostariophysi is the second largest superorder of fishes, formed almost exclusively by freshwater species, with 102 families, 1372 genera, and 11,883 species, thus containing approximately 30% of the known fish species in the world and almost 70% of the ...

Ichthyological Contributions [PDF]

Journal of the Marine Biological Association of the United Kingdom, 1892
In my paper in the preceding number of this Journal I erroneously described several specimens of this species as Zeugopterus punctatus, not having carefully examined or compared them. Since then, having seen specimens of Zeugopterus norvegicus, and re-examined my own, I find that my specimens belong to this species.
