Microbiomes are communities of microorganisms that form close associations with metazoan hosts and have important roles in host biological processes. With the advent of Next Generation Sequencing, the microbiomes of myriad animals and plants have been described. However, the microbiomes of parasites have received little attention, which is surprising considering their ecological and medical importance. This study characterizes, for the first time, the microbiome of Dujardinascaris helicina, a gastrointestinal nematode parasite of the American crocodile. Dujardinascaris helicina were isolated from crocodiles residing in two geographically separated habitats across Belize. Using 16S sequencing, we compare β-diversity between sampling locations using generalized linear mixed modeling. Our results show that D. helicina microbiomes differ in composition depending on location. We also show that D. helicina microbiomes show strong shifts toward consolidation of specific taxa when proximity to human modified environments increases.

The use of camera traps in wildlife conservation and ecological research is a popular method of data capture due in large part to the perceived low interference levels for the animals being studied. However, evidence exists that some species alter their behaviour when exposed to this technology. The primary aim of this study was to address whether researchers working with this technology in the ecology and forestry fields are making considerations for the possible impacts of cameras on animal behaviour. A secondary aim was to investigate how the use of this technology is framed in recent publications. In this rapid systematic literature review, we conducted a search on Web of Science and we identified 267 papers published in the last five years, in the fields of ecology and forestry, that met our inclusion criteria. We screened the studies for mentions of the impact of camera traps on the welfare of wildlife. Surprisingly, only 7.5% of the papers considered the possible animal welfare impacts of camera use on the wildlife species of interest in their study, with most comparing it to invasive methods and therefore framing this technology positively. We strongly encourage researchers working in this field to consider the impact of this technology on the specific species being studied. Whilst we recognise that the use of camera traps avoids direct handling of the animals, the short- and long-term effects of using this technology should not be ignored and should, at a minimum, be acknowledged in the limitations.

Although the interaction between humans and their environments is central to psychological science, its dynamics throughout the lifespan remain unexplored. We consider how ecological affordances—the opportunities and threats an environment poses for one’s goal achievement—can be differently perceived across developmental life stages. Integrating affordance-management and life-history perspectives, we propose that individuals perceive and respond to ecological affordances based on their prioritized goals, which shift systematically as they progress through life stages. The same environment can be perceived as posing an opportunity at one life stage, but as posing a threat or being irrelevant at other stages with different goal priorities. To illustrate the value of this framework, we focus on three environmental dimensions tied to recurring adaptive challenges in human history: genetic relatedness, physical violence, and sex-age ratio. We examine how individuals perceive and navigate ecological affordances across three key life stages—childhood, mating, and parenting—through multiple strategies: (a) recalibrating cognitive and affective attunement to relevant cues, (b) adjusting psychological and behavioral strategies, and (c) reconstructing their environments at various levels. By bridging social, developmental, and cognitive psychology with behavioral ecology and evolutionary biology, this framework advances our understanding of human-environment interactions by (a) challenging the assumption that environmental effects are static, (b) generating precise hypotheses about psychological and behavioral patterns, enabling systematic and holistic investigation, and (c) underscoring the potential for lifelong flexibility in ecological navigation.

Fusing the aesthetics of futurity with the lush beauty of the natural world, planned eco-city developments like Forest City and Penang South Islands, both in Malaysia, promise luxury enclaves against climate change and the environmental stressors of existing cities. This article analyzes CGI architectural renderings used to promote and sell eco-city projects in Southeast Asia. Eco-city renderings, we argue, produce semio-capitalistic value by translating the familiar concepts of “green,” “eco-friendly,” and “sustainable” into something far more inchoate: feelings. They do so through their supersaturation with signs of greenness in a design strategy we label “semiotic overdetermination.” Selling “green” as a feeling, eco-city renderings capitalize on present-day anxieties over urban decay and commodify “the ecological” as a rich resource of pleasurable qualitative experiences. The result, we contend, is to reinforce a neoliberal mode of subjectivity that equates consumption with somatics and reduces climate responsibility to individual consumer decisions.

In 2020 Chinese “dark fleets” replaced North Korean “ghost ships” in international discourse as symbolic of a certain form of global maritime threat and disturbance. This article takes a longer view of trouble on the high seas, looking back to the globalization of the oceanic commons at the behest of post 1945 geopolitics and new forms and methodologies of fisheries science. With Carmel Finley's articulation of Pacific Empires of Fishing in mind the article explores fishing histories of East Asia and the Pacific, both during and after the era of colonization The article considers the marginalization of already peripheral traditional Korean fishing communities by Japanese colonization, ecological collapse generated by the technological and statistical development underpinning scientific fishing, and the ghosts made of fish themselves as the powers and logics of accumulation and extraction transform the watery geographies of the Pacific.

The incredible growth of China's cattle, sheep and dairy production is a visible phenomenon of the past twenty years, but its foundations were laid decades earlier. Seeking to industrialize its hinterland, and exploit its vast wealth of grazing livestock, China created slaughtering and processing facilities across its northern grasslands during the 1950s. Since the 1980s, much of this infrastructure has been privatized by companies which, like their predecessors, seek efficiency through economies of scale. Brutal competition over price and constant arrival of new domestic and foreign players have encouraged the integration of processing chains, but also sidelined small operators, and created gaps in safety best epitomized by the 2008 tainted milk scandal. Despite steps taken to “green” the production chain, it remains to be seen if such gaps have been adequately filled.

Understanding the population structure and genetic diversity of green turtles is crucial for effective conservation. This study investigated the occurrence, genetic composition, and potential origins of green turtles (Chelonia mydas) in the Potiguar Basin, northeastern Brazil, based on stranding data from 2010 to 2019. Analysis revealed that 87.36% of the population consisted of juveniles, primarily females with a curved carapace length (CCL) between 30 and 59.9 cm. Genetic analysis of the mtDNA control region (481 bp, n = 39) revealed eight haplotypes, with CM-A8 (48.7%) and CM-A5 (30.8%) being the most common. This may be related to the geographic position of the Potiguar Basin, located in the ‘corner’ of the South American continent. High haplotype diversity and low nucleotide diversity were observed, consistent with other Brazilian foraging grounds. Mixed stock analysis identified Ascension Island as the primary source population, followed by Guinea-Bissau and Surinam. The results highlight the importance of the Potiguar Basin as a foraging area for green turtles and emphasize the need for comprehensive conservation strategies to protect this vulnerable population.

This study on distribution of Ophiothrix savignyi was carried out from 2017 to 2022 in the Iranian waters of the Persian Gulf. Nineteen locations were sampled from coastal waters, including 16 newly reported areas. O. savignyi was epizoic, associated mostly with sponges, sea urchins, and soft corals. This survey shows O. savignyi as the most common and widespread brittle star in the northern and eastern Persian Gulf. In this study, O. savignyi, has been described again from the Persian Gulf.

The Asian corn borer (ACB), Ostrinia furnacalis (Guenée, 1854), is a serious pest of several crops, particularly a destructive pest of maize and other cereals throughout most of Asia, including China, the Philippines, Indonesia, Malaysia, Thailand, Sri Lanka, India, Bangladesh, Japan, Korea, Vietnam, Laos, Myanmar, Afghanistan, Pakistan and Cambodia. It has long been known as a pest in South-east Asia and has invaded other parts of Asia, Solomon Islands, parts of Africa and certain regions of Australia and Russia. Consequently, worldwide efforts have been increased to ensure new control strategies for O. furnacalis management. In this article, we provide a comprehensive review of the ACB covering its (i) distribution (geographic range and seasonal variations), (ii) morphology and ecology (taxonomy, life-history, host plants and economic importance) and (iii) management strategies (which include agroecological approaches, mating disruption, integrated genetic approaches, chemical as well as biological control). Furthermore, we conclude this review with recommendations to provide some suggestions for improving eco-friendly pest management strategies to enhance the sustainable management of ACB in infested areas.
