Combined stable isotope and gut contents analysis of food webs in plant-dominated, shallow lakes [PDF]

open access: yes, 2003
1. To determine feeding links between primary producers, invertebrates and fish, stable isotope analyses and gut content analyses of fish were conducted on the components of four shallow, eutrophic to hypertrophic, plant-dominated lakes. 2.

Effect of woodstack structure on invertebrate abundance and diversity [PDF]

open access: yes, 2013
Reduced quantities of dead wood in managed forests have resulted in a reduction in the abundance and diversity of saproxylic invertebrates to the extent that many are now considered red list species.

Insecticide Effects on Normal Development and Hatch of Embryos of \u3ci\u3eParatanytarsus Parthenogeneticus\u3c/i\u3e (Diptera: Chironomidae) [PDF]

open access: yes, 2017
Simple, low cost methods are needed to determine the effect of pesticides on non-target aquatic organisms. In this report, embryos of Paratanytarsus parthenogenetic us were exposed from deposition to hatch to five pesticides.

Food webs in forest and pasture streams in the Waikato region, New Zealand: A study based on analyses of stable isotopes of carbon and nitrogen, and fish gut contents. [PDF]

open access: yes, 1997
Stable isotopes of carbon (C) and nitrogen (N) were studied in 11 stream communities in the Waikato region of New Zealand. From comparisons of mean d13C and d15N values, food webs in the shaded, forest streams were clearly based on allochthonous material

Effects of a short-term temperature increase on arthropod communities associated with pastures [PDF]

open access: yesBiodiversity Data Journal, 2023
The impact of climate change on islands is expected to cause dramatic consequences on native biodiversity. However, limited data are available for arthropod communities in island agroecosystems.

New evidence from exceptionally “well-preserved” specimens sheds light on the structure of the ammonite brachial crown

open access: yesScientific Reports, 2021
Ammonite soft body remains are rarely preserved. One of the biggest enigmas is the morphology of the ammonite brachial crown that has, up till now, never been recovered.

First Short-Term Study of the Relationship between Native and Invasive Earthworms in the Zone of Soil Freezing in Western Siberia—Experiments in Mesocosms

open access: yesDiversity, 2023
Earthworm invasions often reduce biodiversity and affect the ability of ecosystems to perform ecosystem functions. Over the past few decades, European lumbricid species have spread widely in natural habitats in Western Siberia, without completely ...

Leptoclinides (Ascidiacea, Didemnidae) from Brazil: new records and two new species

open access: yesEuropean Journal of Taxonomy, 2019
Twenty-two samples of Leptoclinides Bjerkan, 1905 collected along the Brazilian coast between 1998 and 2017 were examined. Herein we describe two new species (Leptoclinides coronatus sp. nov. and Leptoclinides lotufoi sp. nov.).
