Abraham Ekperusi, Ena Suarez

Published: 2024-05-06
Subjects: Life Sciences

The Mangroves of the Gulf of Guinea - South is a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes the Angolan, Gulf of Guinea Central, Gulf of Guinea Islands and Gulf of Guinea South marine ecoregions. The biota is characterized by six species of true mangroves with several associated mangrove species. The majority of the mangroves are found in the [...]

The Value and Urgency of Transportation Forestry

Matthew Browning, Kathleen Wolf, Pamela Murray-Tuite, et al.

Published: 2024-05-06
Subjects: Social and Behavioral Sciences

The community and ecological benefits of trees and forests along roadways and other transportation infrastructure are important. Historically, the dialogue surrounding trees in transportation systems has focused on safety and crash reduction. We propose the sub-field of “Transportation Forestry” to maximize the benefits and minimize the risks of trees and supporting green [...]

Mangroves of the Arabian (Persian) Gulf is a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes the marine ecoregions of the Arabian (Persian) Gulf, Gulf of Aden, Gulf of Oman, Western Arabian Sea and Western India (Asia).

Symbiotic status does not preclude hybridisation in Mediterranean octocorals

Didier Aurelle, Anne Haguenauer, Marc Bally, et al.

Published: 2024-05-05
Subjects: Life Sciences

Understanding how species can form and remain isolated in the marine environment is still an active research area. Correctly delimiting species if also of interest for biodiversity conservation and for a wide range of biological studies. Here we study the differentiation and the possibility of hybridization among three temperate octocorals : Eunicella cavolini, E. singularis and E. verrucosa. [...]

Predator-Prey movement interactions: jaguars and peccaries in the spotlight

Vanesa Bejarano Alegre, Júlia Emi de Faria Oshima, Claudia Zukeran Kanda, et al.

Published: 2024-05-05
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences

Understanding how the landscape influences the distribution and behavior of predators and prey gives us insights into the spatial dynamics of their interactions and the factors that shape their populations across space and time. This study analyzed interactions between jaguars (Panthera onca) and white-lipped peccaries (Tayassu pecari) at different forest and grassland distances and under varying [...]

Revisiting Wolbachia detections: old and new issues in Aedes aegypti mosquitoes and other insects

Perran A Ross, Ary A Hoffmann

Published: 2024-05-05
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences, Microbiology

Wolbachia continue to be reported in species previously thought to lack them, particularly Aedes aegypti mosquitoes. The presence of Wolbachia in this arbovirus vector is considered important because releases of mosquitoes with transinfected Wolbachia are being used around the world to suppress pathogen transmission and these efforts depend on a lack of Wolbachia in natural populations of this [...]

A dire need for better standards of data quality, transparency, and reproducibility in IUCN RedList assessments

Alice Hughes, Michael C. Orr, Ruben D. Palacio, et al.

Published: 2024-05-05
Subjects: Biodiversity, Ecology and Evolutionary Biology

The IUCN RedList is the most extensive source of information on the global extinction risk including over 157000 species. The sheer scale of this initiative presents challenges in data standards and reporting, especially given that legacy issues may reduce accuracy. Here, we assess the bibliographic underpinnings of RedList assessments for five taxa with fairly complete assessments (four [...]

University herbaria are uniquely important

Erika J Edwards, Brent Mishler, Charles Davis

Published: 2024-05-02
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Life Sciences

University herbaria play critical roles in biodiversity research and training and provide an interdisciplinary academic environment that fosters innovative uses of natural history collections. Universities have a responsibility to steward these important collections in perpetuity, in alignment with their academic missions and for the good of science and society.

Quantifying the Value of Community Science Data for Conservation Decision-making

Allison Binley, Jeffrey Hanson, Orin Robinson, et al.

Published: 2024-05-02
Subjects: Life Sciences

Monitoring biodiversity can be critical for informing effective conservation strategies, but can also deplete the resources available for management actions. Freely-available community science data may help alleviate this issue, but only if data quality is sufficient to inform the best decisions. Our objective was to quantify the predicted outcomes of prioritizing conservation action based on [...]

O mapa do tesouro perdido: guias de campo e o seu papel na promoção da conservação

Rachel Turba de Paula, André Hoffmann, Vanessa Fernandes Guimarães

O projeto ‘Guias da Conservação: de turista a naturalista’ surgiu com o propósito de estimular o pensamento conservacionista através da sensibilização do público, utilizando-se da biodiversidade contida na Mata Atlântica na forma de guias de campo. Este trabalho teve como objetivo avaliar a recepção dos guias de campo desenvolvidos pelo projeto. O público alvo foi o público participante do evento [...]

Wildlife health perceptions and monitoring practices in globally distributed protected areas

Diego Montecino-Latorre, Mathieu Pruvot, Sarah H Olson

Published: 2024-04-30
Subjects: Biodiversity, Environmental Monitoring, Epidemiology, Health Information Technology, Health Policy, Life Sciences, Natural Resources and Conservation, Recreation, Parks and Tourism Administration, Sustainability, Veterinary Preventive Medicine, Epidemiology, and Public Health

Diseases are a threat to biodiversity conservation and global health, however, wildlife health (WH) surveillance systems remain uncommon. This deficit is especially relevant in protected areas (PAs) facing anthropogenic pressures. Integration of field conservation actors patrolling PAs can drastically strengthen WH surveillance. Nevertheless, baseline information regarding current WH monitoring [...]

Seasonal patterns of resource use within natural populations of burying beetles

Swastika Issar, Chloé Leroy, Patrizia d'Ettorre, et al.

Published: 2024-04-30
Subjects: Life Sciences

For organisms in temperate environments, seasonal variation in resource availability and weather conditions exert fluctuating selection pressures on survival and fitness, resulting in diverse adaptive responses. By manipulating resource availability on a local spatial scale, we studied seasonal patterns of resource use within natural populations of burying beetles (Nicrophorus vespilloides) in a [...]

Trimming the hedges in a hurricane: Endangered Species lack research on the outcomes of conservation action

Allison Binley, Lucas Haddaway, Rachel Buxton, et al.

Published: 2024-04-30
Subjects: Life Sciences

Given widespread biodiversity declines, there is an urgent need to ensure that conservation interventions are working. Yet, evidence regarding the effectiveness of conservation actions is often lacking. Using a case study of 208 terrestrial species listed as Endangered in Canada, we conducted a literature review to collate the evidence base on conservation actions to: 1) explore the outcomes of [...]

Dissecting transmission to understand parasite evolution

Luis M. Silva, Kayla C. King, Jacob C. Koella

Published: 2024-04-26
Subjects: Life Sciences

The prevailing theory of the evolution of virulence assumes that evolution maximizes its transmission and relies on a trade-off between virulence and the parasite's transmission rate. While this simple idea finds some empirical support, it is often criticized, in part because of its ambiguity about transmission, the key measure of pathogen fitness. In theoretical and empirical studies, [...]

Hijackers, hitchhikers, or co-drivers? The mysteries of microbial mobilizable genetic elements

Eduardo Rocha, Jorge Moura de Sousa, Manuel Ares Arroyo, et al.

Published: 2024-04-26
Subjects: Bacteriology, Evolution, Genetics, Life Sciences, Molecular Biology

Mobile genetic elements shape microbial gene repertoires and population dynamics, but their mechanisms of horizontal transmission are often unknown. Recent results reveal that many, possibly most, bacterial mobile genetic elements require helper elements to transfer between (or within) genomes. We refer to these non-autonomous, albeit mobile, elements as Hitcher Genetic Elements (hitchers or [...]
