Sex on the Beach: Sexual Size Dimorphism Among Aquatic Bugs (Nepomorpha) Inhabiting Different Habitats. [PDF]

open access: yesEcol Evol
We examined the degree of sexual size dimorphism (SSD), based on body length, in approximately 45% of known water bug (Nepomorpha) species. Contrary to our initial hypothesis, we found that females are not significantly longer than males in most species. Our research revealed that habitat plays a significant role in SSD.

Effects of competition and predation risk from a life history intraguild predator on individual specialisation. [PDF]

open access: yesJ Anim Ecol
Individual niche specialisation is widespread within animal populations and can have important ecological consequences. Predation and competition are known drivers of individual specialisation, but their combined effects are unstudied. This mesocosm experiment shows that competition and predation from a single antagonist can have variable effects on ...

Psychometric Properties of the Turkish Version of the Partners in Health Scale: Chronic Disease Self-Management in Primary Healthcare. [PDF]

open access: yesInt J Nurs Pract
ABSTRACT Background This study aimed to assess the psychometric properties of the Turkish version of the Partners in Health Scale (PIH‐TR), which was developed to assess the perceptions of patients with chronic conditions in primary care. Accurate assessment of facilitators and barriers to self‐management of chronic conditions, from the patients ...

The efficacy of DNA barcoding in the classification, genetic differentiation, and biodiversity assessment of benthic macroinvertebrates. [PDF]

open access: yesEcol Evol, 2021
We evaluated the feasibility of DNA barcoding for the classification of benthic macroinvertebrates from four large transboundary rivers of northwest China. Our study shows that DNA barcoding can be used to clarify species boundaries and improve the reliability of environmental and biodiversity assessment in rivers. Abstract Macroinvertebrates have been

Effects of river regulation on aquatic invertebrate community composition: A comparative analysis in two southern African rivers. [PDF]

open access: yesEcol Evol
This study compared aquatic invertebrate communities between a regulated and unregulated river and sought to determine whether the largest inland lake of the region, which receives water from both rivers, resembles the aquatic invertebrate communities of either river.

Diel variation in insect‐dominated temperate pond soundscapes and guidelines for survey design

open access: yesFreshwater Biology, Volume 68, Issue 7, Page 1148-1160, July 2023., 2023
Abstract Passive acoustic monitoring has been used for decades as a non‐invasive tool for quantifying biodiversity in terrestrial and marine ecosystems. Recently, there has been increased interest in the potential for the method to survey freshwater biodiversity.

Invasion of a non‐native anuran likely disrupts pond ecosystems

open access: yesFreshwater Biology, Volume 68, Issue 7, Page 1194-1210, July 2023., 2023
Abstract Freshwater ecosystems worldwide are under increasing pressure from multiple threats, including invasive species and climate change, with ponds being particularly vulnerable because of their shallow depth and dynamic hydrology. Australian brown tree frogs Litoria ewingii, introduced to New Zealand in 1875, have spread across both main islands ...

Discordant pattern between realised and fundamental saline niches in two supralittoral Ochthebius species (Coleoptera: Hydraenidae)

open access: yesEcological Entomology, Volume 48, Issue 3, Page 284-294, June 2023., 2023
Both species are euryhalines, supporting extreme salinity fluctuations. Adults and larvae of Ochthebius quadricollis remained in pools with higher conductivities than Ochthebius lejolisii However, fundamental niche (physiological tolerance) was greater in O. lejolisii. The larvae and eggs of both species were more halotolerant than adults.

Loss of functionally important and regionally endemic species from streams forced into intermittency by global warming

open access: yesGlobal Change Biology, Volume 29, Issue 11, Page 3019-3038, June 2023., 2023
Climate change is increasing dryness in southwestern Australia, causing permanent streams to switch to intermittent flows. Aquatic macroinvertebrates showed seven general responses to drying (i.e., 1980s vs. 2016/17), including localised extinction, persisted but became less common, or became more common.

Development of a flow‐sensitive macroinvertebrate index for Australian rivers

open access: yesRiver Research and Applications, Volume 38, Issue 5, Page 846-862, June 2022., 2022
Abstract Hydrologically sensitive macroinvertebrate indices have been developed in Europe, the Americas and New Zealand to serve many purposes such as monitoring ecological responses to drought, flow regulation, water extraction and the provision of environmental flows.
