Freshwater Biology, Volume 70, Issue 8, August 2025.ABSTRACT Freshwater mussels are in decline worldwide, and their conservation is limited by a lack of understanding of species ecology and biology, particularly in the southern hemisphere. Hyridella narracanensis is a threatened species which is co‐distributed with a more abundant congener, H. drapeta.

Effects of Simulated Student Interaction on Student Perceptions of Teaching Presence [PDF]
, 2017 The purpose of this study was to explore the impact of the instructor posting in online discussions as a simulated student; particularly the impact simulated student interaction (SSI) had on the instructor/student relationship.

A Comparison of Competitive-Orientation Measures [PDF]
, 1991 We compared two sport-specific measures of competitive orientation, the Sport Orientation Questionnaire (SOQ; Gill & Deeter, 1988) and the Competitive Orientation Inventory (COI; Veasley, 1986), and an alternative 4-item version of the COI.

Journal of Fish Biology, Volume 107, Issue 2, Page 454-465, August 2025.Abstract A new species of Characidium is described from the Iguaçu National Park, Brazil. The new species can be diagnosed from the congeners by the absence of conspicuous vertical bars, blotches and spots along the sides of the body, the presence of a scaled isthmus and adipose fin, a series of scales below lateral line and the presence of a thin dark

Ecology and Evolution, Volume 15, Issue 7, July 2025.We used mitochondrial markers to discover highly contrasting phylogeographic patterns in two sister species of supralittoral isopods (genus Tylos) that have largely overlapping distributions along the coast of Chile. Tylos chilensis shows evidence of multiple relatively deep divergence events leading to geographically restricted lineages that appear to

The SARS-CoV-2 neutralizing antibody response to SD1 and its evasion by BA.2.86
Nature CommunicationsUnder pressure from neutralising antibodies induced by vaccination or infection the SARS-CoV-2 spike gene has become a hotspot for evolutionary change, leading to the failure of all mAbs developed for clinical use.

The impact of one-decade ecological disturbance on genetic changes : a study on the brine shrimp Artemia urmiana from Urmia Lake, Iran [PDF]
, 2019 Urmia Lake, the largest natural habitat of the brine shrimp Artemia urmiana, has progressively desiccated over the last two decades, resulting in a loss of 80% of its surface area and producing thousands of hectares of arid salty land.

Ecology and Evolution, Volume 15, Issue 6, June 2025.Insect inventories are often hampered by the hidden diversity of larval stages, but we demonstrate that DNA‐based identification methods are useful to gain insights into species diversity and abundance. ABSTRACT Invertebrates, especially insects, are an integral part of biodiversity.

Ecology and Evolution, Volume 15, Issue 5, May 2025.There is a knowledge gap concerning the genetic diversity distribution across marine invertebrates, and whether the latitudinal genetic diversity gradient results from congruent intraspecific trends. Our results indicate higher genetic diversity in lower latitudes is correlated to productivity and oxygen levels, but does not represent the accumulation ...
