Neural events underlying escape swimming behaviour in the squat lobster 'Galathea strigosa' (Crustacea, Anomura)

open access: yes, 2012
1. The anatomy and physiology of escape swimming behaviour in the squat lobster, Galathea strigosa, have been investigated and the results discussed in the context of comparative mechanisms of escape in rela~ed species. 2.

Gajenje rakova u akvakulturi Južnopanonskog regiona [PDF]

open access: yes, 2015
The purpose of this labour is to find out if it possible to include crayfish into the aquaculture of the South Panonian region. It was necessary to establish which species may be the most suitable for the given region, as well as the locality from which ...

Flooding affects fluctuating asymmetry but not growth of a riparian orbweaving spider

open access: yesEcological Entomology, Volume 51, Issue 3, Page 547-557, June 2026.
In a mesocosm experiment we assessed the impact of flood on aquatic insect emergence and on spider development using geometric morphometric analysis of fluctuating asymmetry. We observed 45% higher emergence in flooded mesocosm throughout the season. Spiders did not grow bigger but exhibited ~15% lower fluctuating asymmetry than in controls.

Flow Cytometric Enumeration of the Blood Cells of Rainbow Trout (Oncorhynchus mykiss) and New Zealand Freshwater Crayfish (Paranephrops planifrons)

open access: yes, 2009
The aim of this study was to develop flow cytometric (FC) methods to enumerate rainbow trout (Oncorhynchus mykiss) whole blood cells and New Zealand freshwater crayfish (Paranephrops planifrons) haemocytes as non-lethal endpoints in the evaluation of ...

Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段

open access: yesEcological Entomology, Volume 51, Issue 3, Page 592-603, June 2026.
The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

Freshwater Mussel Anodonta cygnea Reduces Concentration, Germination Rate and Infectivity of Pathogenic Oomycete Saprolegnia spp. Spores

open access: yesFreshwater Biology, Volume 71, Issue 6, June 2026.
ABSTRACT Saprolegniosis, also known as water mould, is a lethal disease caused by Saprolegnia oomycetes that threatens freshwater animals including fish, amphibians, and crustaceans, as well as aquaculture. It causes biodiversity loss and population declines, including those of endangered fishes.

Native and Non‐Native Populations Respond Unevenly to River Barrier Removals

open access: yesGlobal Change Biology, Volume 32, Issue 6, June 2026.
While barrier removals restore river connectivity and promote recovery of native populations, they may also facilitate non‐native species, creating a ‘connectivity conundrum’. Using a systematic review and meta‐analysis, we show that both native and non‐native populations can benefit from barrier removal, with outcomes being context‐dependent ...

The Integration of Fire Ecology and Freshwater Ecosystems in North America: Knowledge Gaps and Research Needs

open access: yesGlobal Change Biology, Volume 32, Issue 6, June 2026.
Illustration of key knowledge gaps and pathways linking fire ecology and freshwater ecosystems. Climate change provides the overarching context, interacting with cumulative and cross‐scale effects to shape local freshwater conditions. Within this context, fire characteristics influence three primary pathways within freshwater ecosystems: species and ...
