Coral bleaching events, in which symbionts are lost from host tissues, have become more frequent and severe because of climate change—specifically, elevated temperatures. How such events impact biogenic volatile organic compound (BVOC) emissions, compounds that can function as metabolic signalling elements, remains underexplored. Here we used gas chromatography coupled with mass spectrometry (GC–MS) to characterise the suite o...

Global conservation maps often overlook community lands, impacting decision-making and reducing local agency. We focus on the high-profile and regionally important case of Massaha’s ancestral territory (Ibola Dja Bana Ba Massaha). In Gabon, the forest is largely gazetted into logging concessions and described as an Eden-like wilderness despite long-term human presence. We compare Massaha’s biocultural maps to global, colonial,...

At high latitudes, hibernating species must replenish their energy reserves within a 4–6 month active season. During this window, insectivorous bats at higher latitudes must consume sufficient arthropod prey to support reproduction and migration, despite suboptimal weather and prey abundance that varies across time and space. Local declines in body size of endangered little brown bats ( Myotis lucifugus ) suggest ongoing nutri...

The continuous exchange of molecular signals between partners in the cnidarian–dinoflagellate symbiosis is fundamental for maintaining a healthy relationship. This homeostasis is affected by rising seawater temperatures resulting from climate change (i.e., coral bleaching), though little is known about how these molecular signals are altered. Here, we investigated the localisation and abundance of four receptors in the sea ane...

The symbiotic relationship of cnidarians with dinoflagellates of the family Symbiodiniaceae is based on host-symbiont recognition processes and continuous molecular exchange between partners. However, the molecular signals involved are unresolved. Oxylipin signalling plays a pivotal role in mediating various cellular processes, including inflammation and molecular signalling. Its function in the cnidarian-dinoflagellate symbio...

The two egg parasitoids Enoggera nassaui (Girault) and Neopolycystus insectifurax Girault (both Hymenoptera: Pteromalidae) are biological control agents of the eucalyptus-defoliating paropsine leaf beetle Paropsis charybdis Stål (Coleoptera: Chrysomelidae), an invasive species in New Zealand. Recently another leaf beetle, Paropsisterna cloelia (Stål) (Coleoptera: Chrysomelidae), has established in New Zealand, causing defoliat...

Aim To evaluate (1) whether three migratory nightjar species (Family Caprimulgidae) adhere to Bergmann's rule, (2) whether environmental factors on the breeding or wintering grounds determine body size, and (3) which mechanistic hypotheses best explain Bergmannian patterns in body size. Location North and South America; Europe and Africa. Taxon Eastern whip‐poor‐will ( Antrostomus vociferus ), Common nighthawk ( Chordeiles min...

We examined the effects of symbiont identity and heat stress on the host metabolome and proteome in the cnidarian–dinoflagellate symbiosis. Exaiptasia diaphana (‘Aiptasia’) was inoculated with its homologous (i.e., native) symbiont Breviolum minutum or a heterologous (i.e., non‐native) symbiont ( Symbiodinium microadriaticum ; Durusdinium trenchii ) and thermally stressed. Integrated metabolome and proteome analyses characteri...

Oxylipin signalling is central in biology, mediating processes such as cellular homeostasis, inflammation and molecular signalling. It may also facilitate inter‐partner communication in the cnidarian‐dinoflagellate symbiosis, though this aspect remains understudied. In this study, four oxylipin receptors were characterised using immunohistochemistry and immunoblotting in the sea anemone Exaiptasia diaphana (‘Aiptasia’): Prosta...

The shape of sagitta otoliths was used to compare individuals of little tunny (Euthynnus alleteratus) harvested on board commercial fishing vessels from the coastal areas along the Eastern Atlantic, including the Mediterranean Sea. Fish sampling and selection was designed to cover possible seasonal changes and tuna size. The research encompassed both morphometric and shape analyses of left sagittal otoliths extracted of 504 fi...

Previous work suggests that juvenile salmon recruitment in rain‐fed rivers is negatively influenced by warm and wet winters and cool springs. We tested whether this is generally applicable to a southern England chalk stream characterized by comparatively stable discharges and temperatures. We found that warm spawning and cool emergence temperatures negatively influenced juvenile recruitment between 2015 and 2020. Together thes...

Invasive species can significantly impact native wildlife by structurally altering habitats and access to resources. Understanding how native species respond to habitat modification by invasive species can inform effective habitat restoration, avoiding inadvertent harm to species at risk. The invasive graminoids Phragmites australis australis (hereafter Phragmites ) and Typha × glauca are increasingly dominating Nearctic wetla...
