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.

Feeding behavior of the Amazonian Water Snake Helicops hagmanni Roux, 1910 (Reptilia: Squamata: Colubridae: Hydropsini) [PDF]

Boletim do Museu Paraense Emílio Goeldi. Ciências Naturais, 2008
The genus Helicops currently comprises 15 species, of which eleven occur in the Amazon Forest. H. hagmanni feeds on fishes and has nocturnal habits, but detailed data about its diet and behavioral ecology are scarce. Here, we report a H.

Toltrazuril (Baycox® vet.) in feed can reduce Ichthyophthirius multifiliis invasion of rainbow trout (Salmonidae) [PDF]

Acta Ichthyologica et Piscatoria, 2011
Various compounds have been applied for control of Ichthyophthirius multifiliis (commonly known as Ich) which is the parasitic pathogen, responsible for the white spot disease, in freshwater aquaculture worldwide.  Available methods are based on

Uncharted digenean diversity in Lake Tanganyika: cryptogonimids (Digenea: Cryptogonimidae) infecting endemic lates perches (Actinopterygii: Latidae)

Parasites & Vectors, 2020
Background Lake Tanganyika is considered a biodiversity hotspot with exceptional species richness and level of endemism. Given the global importance of the lake in the field of evolutionary biology, the understudied status of its parasite fauna is ...

Quantifying Bone Collagen Fingerprint Variation Between Species

Molecular Ecology Resources, Volume 25, Issue 4, May 2025.
ABSTRACT Collagen is the most ubiquitous protein in the animal kingdom and one of the most abundant proteins on Earth. Despite having a relatively repetitive amino acid sequence motif that enables its triple helical structure, in type 1 collagen, that dominates skin and bone, there is enough variation for its increasing use for the biomolecular species

A Comprehensive Evaluation of Taxonomic Classifiers in Marine Vertebrate eDNA Studies

Molecular Ecology Resources, EarlyView.
ABSTRACT Environmental DNA (eDNA) metabarcoding is a widely used tool for surveying marine vertebrate biodiversity. To this end, many computational tools have been released and a plethora of bioinformatic approaches are used for eDNA‐based community composition analysis.

Phylogenetic Classification of Living and Fossil Ray-Finned Fishes (Actinopterygii)

Bulletin of the Peabody Museum of Natural History
Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the designation of taxonomic groups based on morphological similarity. Starting in the late 1960s morphological phylogenetics became the basis for the classification of Actinopterygii but failed to resolve many relationships, particularly among lineages within ...

The timing of Timezyme diversification in vertebrates. [PDF]

PLoS ONE, 2014
All biological functions in vertebrates are synchronized with daily and seasonal changes in the environment by the time keeping hormone melatonin. Its nocturnal surge is primarily due to the rhythmic activity of the arylalkylamine N-acetyl transferase ...

Chromosome‐Level Genome Assembly of the Loach Goby Rhyacichthys aspro Offers Insights Into Gobioidei Evolution

Molecular Ecology Resources, EarlyView.
ABSTRACT The percomorph fish clade Gobioidei is a suborder that comprises over 2200 species distributed in nearly all aquatic habitats. To understand the genetics underlying their species diversification, we sequenced and annotated the genome of the loach goby, Rhyacichthys aspro, an early‐diverging group, and compared it with nine additional Gobioidei
