Spiders as surrogate species in ecological monitoring, habitat classification and reserve selection : a thesis presented in partial fulfilment of the requirements for the degree of Masters of Science in Ecology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2001
The use of invertebrates in the monitoring of terrestrial ecosystems was investigated using spiders as a focal group. In a review of previous literature, spiders were found to meet the majority of criteria required of suitable ecological indicators ...

Diversity Patterns of Domestic Herbivore Viruses in China Reveal Transmission Dynamics with Disease Management Implications

open access: yesAdvanced Science, EarlyView.
This study performs pan‐viromic profiling of 14,529 samples from 5,710 domestic herbivores across five Chinese provinces, establishing the DhCN‐Virome (1,085,360 viral metagenomes). It reveals species/sample‐specific viromic signatures and cross‐species transmission dynamics, aiding unified disease control.

The role of serine hydroxymethyltransferase 1 (CHSHMT1) in the regulation of the key osmolyte glycine in the estuarine Hong Kong oyster Crassostrea hongkongensis under osmotic stress

open access: yesAquaculture Reports
The estuarine Crassostrea hongkongensis is the major cultured oyster species in the South China, and mass mortality induced by hyper-salinity has heavily damaged the oyster farming, especially during dry season.

The Influence of Canopy Cover on the Ecological Function of A Key Autogenic Ecosystem Engineer

open access: yesDiversity, 2019
Intertidal fucoid algae can function as ecosystem engineers across temperate marine regions. In this investigation, we assessed the function of the alga dominating rocky reefs in temperate Australia and New Zealand, Hormosira banksii.

Taxonomical study of ciliates species (Order: Holotricha) in Zayandeh Rud River and the reservoirreservoir [PDF]

open access: yesبوم‌شناسی آبزیان, 2023
Ciliates are among the largest classes of protozoans. They can be found in almost every aquatic environment. Ciliates serve as an intermediate link in the energy transfer chain from picoplankton to zooplankton.

The evolution and comparative neurobiology of endocannabinoid signalling [PDF]

open access: yes, 2012
CB(1)- and CB(2)-type cannabinoid receptors mediate effects of the endocannabinoids 2-arachidonoylglycerol (2-AG) and anandamide in mammals. In canonical endocannabinoid-mediated synaptic plasticity, 2-AG is generated postsynaptically by diacylglycerol ...

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

open access: yesAdvanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Global invasion history with climate-related allele frequency shifts in the invasive Mediterranean fruit fly (Diptera, Tephritidae: Ceratitis capitata)

open access: yesScientific Reports
The Mediterranean fruit fly (Ceratitis capitata) is a globally invasive species and an economically significant pest of fruit crops. Understanding the evolutionary history and local climatic adaptation of this species is crucial for developing effective ...

The response of perennial and temporary headwater stream invertebrate communities to hydrological extremes [PDF]

open access: yes, 2009
The headwaters of karst rivers experience considerable hydrological variability, including spates and streambed drying. Extreme summer flooding on the River Lathkill (Derbyshire, UK) provided the opportunity to examine the invertebrate community response
