Abstract Effects of anthropogenic activities, including climate change, are modifying fire regimes, and the dynamic nature these modifications requires identification general patterns organisms’ responses to fire. This is a challenging task because high complexity factors involved (including climate, geography, land use, species‐specific ecology). We aimed describe reptile community across range environmental fire‐history conditions in western Mediterranean Basin. sampled 8 sites that spanned 4 countries. recorded 6064 sightings 36 species 1620 transects modeled 3 metrics (total number individuals, richness, Shannon diversity) as variables. Reptile composition was also analyzed. Habitat type (natural vs. afforestation), age class (time since last fire), rainfall, temperature were important explaining metrics. The total individuals varied according class, reaching peak at 15–40 years after Species richness diversity more stable during postfire years. higher under than unburned forest plots. pattern particularly prevalent afforested plots, indicating negative effect on reptiles lower afforestation. Community by existence early‐ late‐successional (xeric saxicolous mesic reptiles, respectively). 46% areas with single relative those mixture classes, which indicates pyrodiverse landscapes promoted diversity. An expected shift frequent fires will bias distribution toward predominance early stages, this be harmful communities.

Human and nature relations in Hooykaas Christiaan’s Enige Sasakse Volksvertelsels (Lombok): An ecocritical study

Research Journal in Advanced Humanities, Год журнала: 2024, Номер 5(1)

Опубликована: Янв. 9, 2024

This study explores the intricate relationship between humans and nature, as depicted in Sasak tribal folklore “Enige Sasakse Volksvertelsels (Lombok)” by Dr. C. Hooykaas employs Greg Garrard’s literary ecocriticism. The delineates human-nature into two facets: subjects objects relation to nature. former portrays viewing nature mother of Earth, guided ethics care a holistic understanding Conversely, latter reveals instances violence exploitation By examining these dimensions, this research aims foster discussions on environmental conservation integrate awareness regarding its significance. Furthermore, contributes expansion criticism, particularly within realm It serves valuable initiative for preserving local wisdom people Lombok Island, Indonesia, emphasising urgency consciousness.

The agony of choice: Comparing abundance estimates from multiple N-mixture model variants for a dataset of reptile observations

Research Square (Research Square), Год журнала: 2024, Номер unknown

Ecological surveys rarely achieve perfect detection of target species, and failure to account for imperfect can produce erroneous estimates abundance. N-mixture models variation in detectability by separating the observation process from ecological that determines true site-level abundance, making these theoretically well-suited studies inconspicuous such as reptiles. Multiple model variants have been published, but little is known about their ability provide ecologically realistic abundance real-world data. Given novelty potential wider use, help users decide which variant use a particular case would be valuable. If different, yet data-appropriate substantially incongruent same dataset, then uncritical ecology problematic. Using dataset reptile observations south-eastern Zimbabwe, we compare five variants. For each assess congruence between variant. We novel metric performance based on precision feasibility its estimates, accounting goodness-of-fit. find pairs were congruent varies significantly according species occupancy probability. framework application multiple faunal guide analytical decision-making.

Les serpents « sentinelles » de la qualité des habitats : vers une meilleure prise en compte des vipères dans les espaces naturels gérés

Les reptiles sont particulièrement exposés à la dégradation des habitats une échelle mondiale et encore victimes de biais perception méconnaissance. travaux récents montrent l’importance microhabitats pour les notamment dans le contexte l’intensification pratiques changements climatique en cours. Le fort déclin constaté Europe Vipère péliade (Vipera berus (Linnaeus, 1758)) aspic aspis souligne vulnérabilité ces espèces leur rôle indicateur. Dans ce il est important d’évaluer prise considération au sein espaces naturels gérés. résultats d’une vaste enquête France Belgique (Wallonie) ont révélé que sur 208 sites gérés, 60 % gestionnaires connaissance moyenne ou mauvaise deux peu mises place suivis (50 25 aspic). Cette faible compte entraîne incapacité évaluer tendance populations vipères sites. cas où constatée par gestionnaire, cause plus souvent inconnue. De plus, près trois quarts gérés connues ne bénéficient pas d’actions ciblées préservation. essentiels maintien biodiversité devient urgent prendre besoins gestion. Des mesures simples visant maintenir hétérogénéité peuvent être efficaces.
