Amphipods

, 2022
Until now, ten alien amphipod species have become established in Switzerland, of which five are considered invasive. These species are partly predatory or are filter-feeding and can reach very high densities. Until now they have only been found in larger bodies of water, however.

Early life history of the Korean seahorse, Hippocampus haema: Evidence for direct settlement and ontogenetic shifts in snout morphology

Journal of Fish Biology, EarlyView.
Abstract Early life‐history traits of seahorses are closely linked to juvenile survival, dispersal potential and the onset of substrate attachment; however, detailed stage‐resolved descriptions remain limited for many Hippocampus species. This study examined reproductive behaviour and early ontogenetic development of the Korean seahorse, Hippocampus ...

Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary

Journal of Fish Biology, EarlyView.
Abstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

Journal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

Contribution of rare and common species to subterranean species richness patterns

Ecology and Evolution, 2019
Aim Common species contribute more to species richness patterns (SRPs) than rare species in most studies. Our aim was to test this hypothesis using a novel model system, species living exclusively in subterranean habitats.

Enrichment‐Based Duplex PCR for Early Detection of Potentially Virulent Vibrio harveyi in Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Vibrio harveyi is an important bacterial pathogen in marine aquaculture, responsible for outbreaks affecting a wide range of fish species. Early detection of potentially virulent isolates in fish and environmental samples is essential for effective disease prevention and management, particularly under field conditions where the pathogen may be

Development of a Multiplex Polymerase Chain Reaction Assay for Differentiating Three Lactococcus Species Associated With Piscine Lactococcosis

Journal of Fish Diseases, EarlyView.
ABSTRACT Piscine lactococcosis is an important bacterial disease of farmed fish. The causative agents, Lactococcus garvieae, Lactococcus petauri and Lactococcus formosensis, are closely related, which complicates species‐level identification. We developed a conventional multiplex PCR assay targeting species‐specific genes identified by comparative ...

Innervation of an amphipod heart [PDF]

Journal of the Marine Biological Association of the United Kingdom, 1954
SummaryIn the heart of Marinogammarus marinus three systems of nerve elements have been found, viz. (1) a local system consisting of a ganglionic trunk situated on the dorsal surface of the heart and sending branches to the muscle fibres, (2) two paired nerves, termed the 1st and 2nd cardiac nerves, connecting the local system with the central nervous ...
