Ecological studies on some lakes of the Amazon valley

open access: yes, 1967
Of the three types of lakes studied, clear water, white water, and brown water, the white water lakes are the only ones to have a reasonable autochtonous production of organic matter. Owing probably to the lack of mineral salts, the primary production is

Contemporary Methods for Capturing Juvenile Salmonids in the Marine Environment

open access: yesFish and Fisheries, Volume 27, Issue 2, Page 160-178, March 2026.
ABSTRACT Anadromous salmonids play vital roles in marine and freshwater ecosystems. The most abundant of these fishes—Pacific salmon (Oncorhynchus spp.)—are integral to coastal ecosystems and communities across the North Pacific Rim, but numerous populations are experiencing dramatic declines, particularly towards the south of their range.

Taking machine learning with a grain of sand: Sediment Analysis Neural‐network Data‐engine (SAND‐e) reveals sedimentological differences between turbid and clear‐water reefs

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Using machine learning, researchers can count and crudely identify sand grains from coral reefs automatically. This will allow us to generate larger datasets to answer sedimentological questions. Abstract Sediment is an important facet of sand cay reefs as it is responsible for reef accretion and island formation, with shifts in the proportions of ...

Where Dinner Roams: The Role of Feral Horses as a Resource Subsidy for Wolves and Cougars in West‐Central British Columbia

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
In west‐central British Columbia, large populations of feral horses overlap with native species like caribou and predators such as wolves and cougars, potentially disrupting predator–prey dynamics. Between 2019 and 2025, researchers documented multiple instances of wolf and cougar predation on feral horses—the first such confirmed cases in the region ...

Putting Insects on the Agenda: An Analysis of Actors in Multiple Streams for Biodiversity Conservation Policy in Germany

open access: yesEnvironmental Policy and Governance, Volume 36, Issue 1, Page 66-80, February 2026.
ABSTRACT The loss of biodiversity presents one of the most pressing societal challenges of our time. Insects play a crucial role for biodiversity in terms of ecosystem services and food provision. Although insects receive increasing public and academic attention, the development of policy mixes for insect conservation remains challenging.
