The fingerprint of functional strategies in Mediterranean seagrass fish assemblages

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In the Mediterranean Sea, fish assemblages associated with seagrasses host a relevant percentage of the total fish biodiversity. While the structural complexity, coverage and distribution of seagrasses are known to influence species richness and abundance, their effect ...

Abiotic variables drive different aspects of fish community trait variation and species richness across the continental United States

Journal of Animal Ecology, EarlyView.
Trait distributions provide insight into how niches overlap within a broader trait space. By integrating individual‐level trait observations from different communities, we can explore how facets of trait dimensionality vary across environmental conditions.

Records of anglerfishes (Actinopterygii: Lophiiformes: Lophiidae) from Indonesia [PDF]

Acta Ichthyologica et Piscatoria, 2016
Background. The lophiid anglerfishes are with commercial importance, but rarely they are documented in Indonesian waters. During the Japanese and Indonesian collaborative surveys in 2004 and 2005, an anglerfish collection was made and it is the aim of this study to identify this collection, to document new records and to provide information further ...

Linking geographic distribution and niche through estimation of niche density

Journal of Animal Ecology, EarlyView.
Species with larger climatic tolerances (niches) may have large or small geographic ranges, dependent on the commonness of favourable climatic conditions across geographic space. Here, we explore the relationship between geographic range size and niche area, while also proposing a novel measure of niche density.

The Reproductive Season of the Highland Stoneroller, Campostoma spadiceum, Evidenced by Museum Specimens [PDF]

, 2019
The Highland Stoneroller (Campostoma spadiceum) was described as a distinct species in 2010. Since then, the only study specific to this species is a survey of distribution, and nothing is known about reproduction.

An African twin to the Brazilian Calamopleurus (Actinopterygii: Amiidae) [PDF]

Zoological Journal of the Linnean Society, 1998
Abstract A new species of amiid fish, Calamopleurus africanus sp. nov., is described on the basis of fragmentary material from? Albian Kem Kem beds of southern Morocco. The new species shows several derived characters of the genus Calamopleurus such as ossified dermopterotic ribs, an inferred loose association between the dermosphenotic and the ...

The iNaturalist Species Classification and Detection Dataset [PDF]

, 2018
Existing image classification datasets used in computer vision tend to have a uniform distribution of images across object categories. In contrast, the natural world is heavily imbalanced, as some species are more abundant and easier to photograph than ...

A Comparison of the Innate and Adaptive Immune Systems in Cartilaginous Fish, Ray-Finned Fish, and Lobe-Finned Fish

Frontiers in Immunology, 2019
The immune system is composed of two subsystems—the innate immune system and the adaptive immune system. The innate immune system is the first to respond to pathogens and does not retain memory of previous responses.
