Seasonal changes in abundance of brown trout (Salmo trutta) and rainbow trout (s. gairdnerii) assessed by drift diving in the Rangitikei river, New Zealand

open access: yes, 1985
Numbers and approximate sizes of brown trout (Salmo trutta L.) and rainbow trout (5. gairdnerii Richardson) were estimated by snorkel divers at 6 sites in the middle reaches of the Rangitikei River, North Island, New Zealand, over 14 months.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Improving foaming properties of fish gelatin by neutral protease and gum arabic

open access: yesnpj Science of Food
Neutral protease and gum arabic (GA) were combined to enhance foaming ability (FA) and foaming stability (FS) of fish gelatin. Meanwhile, structural changes of pure, single-modified and combined-modified fish gelatins were evaluated in detail to ...

PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

open access: yesEcography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Enemy release: loss of parasites in invasive freshwater bivalves Sinanodonta woodiana and Corbicula fluminea

open access: yesEcography, EarlyView.
Invasive freshwater bivalves harm native species, ecosystems and biodiversity, and incur economic costs. The enemy release hypothesis posits that invasive species are released from enemies during the invasion process, giving them a competitive advantage in the new environment.

Effect of Flaxseed Gum on the Gelling and Structural Properties of Fish Gelatin

open access: yesFishes
Fish gelatin (FG) has garnered significant attention as an alternative to mammalian gelatin, primarily attributed to its distinct advantages. These include the absence of epidemic transmission risks and the lack of religious restrictions, making it a ...

Brown bullhead catfish (ameiurus nebulosus) in Lake Taupo

open access: yes, 2003
Brown bullhead catfish (Ameiurus nebulosus) were first discovered in Lake Taupo during the early 1980s and are believed to have originated from an illegal liberation into the southern end of the lake.

Relationship between home range and population density in mammals: the role of sociality, territoriality and habitat dimensionality

open access: yesEcography, EarlyView.
Organisms' energy requirements increase with body mass, leading to larger home range areas and lower population density. Previous research has highlighted the differential scaling of these variables in mammals, where species with large home ranges have higher density than expected due to increased home range overlap. Here we investigate this phenomenon
