Continuous monitoring is essential to maintain up-to-date information about their status and to inform adaptive conservation planning. This study provides new baseline information on waterbird assemblages in two poorly studied natural protected areas (PAs) of the San Matías Gulf, in northern Argentine Patagonia. Over the course of a year, bird counts from fixed points were conducted at six sites within these PAs. We hypothesized that avian assemblages would vary primarily according to the protection level of each site, alongside a seasonal component regulating fluxes of migratory and resident species. We recorded total abundance and species richness for each site. Along with the bird counts, we recorded potential environmental and anthropogenic stressors. We recorded nearly 20 000 individuals across both PAs, belonging to 36 species of waterbirds, including Vulnerable and Near Threatened species such as <i>Tringa flavipes</i>, <i>Tringa melanoleuca</i> and <i>Phoenicopterus chilensis</i>. Species richness and abundance vary within each PA. Assemblage composition varied across sites and seasons, with more strictly protected sites supporting higher overall bird abundance and species richness. We observed an arrangement of species' guilds' abundance in accordance with type of substrate and presence of vegetation, while anthropogenic variables had a weak correlation with guilds' abundance.

The reduction in vegetation density and height resulting from fire affects the reproductive success of birds by increasing the likelihood of nest predation and may modify the relative importance of different predator types to nest fate. Streams grasslands are preferred breeding sites for grassland birds in the Southern Pampas of Argentina, in a context of intensive agriculture and grazing. We investigated how post-fire vegetation recovery influences the relative importance of different nest predators. We displayed 48 artificial nests in burned and unburned streams during the first and second years after fire. Principal Component Analysis (PCA) was used to characterize vegetation structure and Bias-reduced Logistic Regression to evaluate predator-specific predation probabilities. Total vegetation cover was significantly reduced in burned streams during the first year, followed by significant recovery in the second year, particularly in the tallest strata. PCA revealed a strong gradient of vegetation height and structural complexity that was closely associated with nest-failure patterns. Predation attributed to olfactory predators (medium-sized mammals) was associated with tall and dense vegetation in unburned streams, whereas predation by visual/thermal predators (snakes, birds, and small mammals) was more frequent in burned streams characterized by open vegetation. Furthermore, predation by visual/thermal predators was significantly more likely in burned than in unburned streams. These patterns became less pronounced as vegetation recovery followed the year. Our results are consistent with the idea that fire-driven vegetation succession acts as an ecological filter, mediating nest predation through shifts in predator-specific detection opportunities. This sensory-based segregation of predator activity may represent an important mechanism linking fire, vegetation structure, and reproductive success in grassland birds, with implications for grassland management and bird conservation.</p>\u0000 </div>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"51 11","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149355880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We test this prediction by performing a perturbation experiment in a three trophic level stream assemblage with a top omnivorous shrimp, two primary consumers (ephemeropterans and chironomids) and periphyton as the basal resource. We used electricity at different intensities to produce (1) exclusion of shrimp and (2) exclusion of shrimp and ephemeropterans. Nine repetitions of the experiment, some with replication, were executed in the same area over 5 years and comprised different experimental configurations. We paired each exclusion treatment to its respective control treatment and analysed the before and after exclusion as an effect size and compared the exclusion with the control. Our results strongly suggest the existence of a trophic cascade of shrimp acting negatively on ephemeropterans that are grazers of periphyton. In the absence of shrimps, ephemeropterans increased in density on average to 3.1 times their density in controls, which led to a decrease of periphyton chlorophyll to 0.28 times that with shrimps and a decrease in periphyton dry mass to 0.5. With the exclusion of ephemeropteran grazers, periphyton chlorophyll and dry mass increased 3.5 and 3.7 times respectively. Chironomids did not consistently increase or decrease with exclusion treatments.

Satellite-derived vegetation indices provide a valuable approach for assessing canopy-level responses to drought over broad spatial and temporal scales. However, indices such as the Enhanced Vegetation Index (EVI) should be interpreted as indicators of canopy greenness and spectral vegetation condition rather than as direct measurements of net primary productivity or ecological recovery. Here, we assessed EVI-derived canopy greenness, climatic associations and spectral stability of central Chilean sclerophyll forests during the 2010–2025 megadrought and a 2019–2021 nested hyperdrought disturbance phase. We analysed sclerophyll forest sectors distributed across the current latitudinal and physiographic range of this forest type in central Chile, from coastal areas to the interior depression and Andean foothills. Annual high-greenness EVI composites were derived from Landsat imagery using the 90th percentile of valid observations, with the 2000–2009 period used as the pre-megadrought spectral reference condition. Extreme EVI anomalies were estimated relative to this reference period. Annual precipitation anomalies and cumulative precipitation deficit were calculated from CHIRPS Daily precipitation data using a 1981–2009 hydroclimatic baseline, while warm-season land surface temperature was derived from Landsat surface temperature products. Climate–EVI associations were evaluated using sector-year regression models with cluster-robust standard errors, and EVI-derived resistance, recovery, and resilience were quantified using bounded ecological stability metrics. Annual P90 EVI showed marked spatial heterogeneity across the study sectors. Lower EVI-derived canopy greenness was generally observed in northern and drier sectors, whereas higher values tended to occur in more southern or locally mesic sectors. Annual EVI was positively associated with precipitation anomalies and negatively associated with warm-season land surface temperature, with the thermal association showing the stronger effect. Extreme negative EVI anomalies were concentrated during the 2019–2021 nested hyperdrought disturbance phase, especially in northern and central sectors. Stability metrics indicated moderate to high EVI-derived resistance across most drought-only sectors, but recovery and resilience varied among sectors during the 2022–2025 post-hyperdrought trajectory. Overall, our results show that central Chilean sclerophyll forests exhibited spatially heterogeneous canopy-level spectral responses to prolonged drought and nested hyperdrought conditions.

Whether urban environments promote convergence toward a single ‘urban strategy’ or allow the coexistence of multiple ecological strategies remains a central question in urban ecology. Here, we examined how two closely related native pigeons, the Spot-winged Pigeon (<i>Patagioenas maculosa</i>) and the Picazuro pigeon (<i>Patagioenas picazuro</i>), partition habitats across multiple spatial scales of urban environments in the southwestern Pampas region, Argentina. At the transect scale, both species occurred in broadly similar urban environments and selected areas with greater tree cover and reduced bare soil, indicating shared dependence on urban green infrastructure. However, consistent interspecific differences emerged: Spot-winged Pigeon showed greater tolerance for built-up conditions, whereas Picazuro pigeon was more strongly associated with arboreal structure and avoided areas with taller buildings. At finer spatial scales, both species preferentially used more open microhabitats than expected from availability, suggesting convergence toward structurally open sites likely linked to foraging efficiency and vigilance. Abundance models further revealed divergent environmental drivers, with Spot-winged Pigeon weakly associated with herbaceous cover and Picazuro pigeon strongly dependent on tree cover. Nest-site characteristics reinforced these contrasts, as Picazuro pigeon selected denser canopies, whereas Spot-winged Pigeon nested in more open substrates. Together, our results indicate that closely related species can follow different ecological pathways to urban integration, shaped by their natural-history affinities. These findings support the view of cities as heterogeneous mosaics that enable ecological divergence rather than homogenization, advancing our understanding of how native species integrate into urban ecosystems.</p>\u0000 </div>","PeriodicalId":8663,"journal":{"name":"Austral Ecology","volume":"51 11","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149312278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to quantify the demographic rates of 31 tree species, considering different biogeographic origins (tropical or temperate) and leaf habits (evergreen or deciduous), and comparing them between two ontogenetic stages (juveniles and adults) in the Araucaria Forest, within the subtropical portion of the Brazilian Atlantic Forest. Demographic parameters were assessed through tree recruitment, mortality, and turnover rates of juveniles and adults, and the population growth rates of trees in mature forests over approximately five years. We used generalized linear models to evaluate how biogeographic origin, leaf habit, and ontogenetic stage shape demographic rates. We found that recruitment, mortality, and turnover rates varied across ontogenetic stages, with juveniles exhibiting higher annual rates than adults. In contrast, population growth rates were not associated with biogeographic origins and leaf habits. Variation in demographic rates reflects distinct responses between juveniles and adults related to species life histories and ontogenetic shifts, likely driven by differences in environmental pressures experienced throughout their life cycle.

Two important considerations in the design of camera surveys are (a) the number of detection units (cameras or camera-groups) per site and (b) deployment time. The trade-off between these two factors will likely affect data quality and quantity, but there is little information about their relative influence on species detectability. In this study we investigated the trade-off between deploying more detection units or extending the length of the sampling period on two frequently assessed variables in camera trapping studies—species richness and detection probability. Camera traps were established along ten transects in the Central Highlands of Victoria, Australia, to target small, medium and large native mammals. We used a bootstrapping procedure to iteratively sample each possible combination of detection units (1–6 camera pairs) and deployment days (1–34). The procedure randomly resampled the data with replacement, repeating the process 1000 times for every combination and calculated (a) the number of species detected and (b) species-specific daily detection probability at each iteration. Multiple detection units in combination with longer deployment times were necessary to detect a high proportion of species present. Increasing the number of detection units or deployment time (or both) resulted in high overall detection probability for the more detectible species in our study region, but multiple detection units were always needed to achieve high detection probability in a reasonable timeframe (&lt; 50 days) for less detectible species.

In South Africa, however, recent climate change has been characterised primarily by increasing temperature extremes rather than shifts in mean conditions. We assessed vegetation greenness and phenology using enhanced vegetation index (EVI) data from 154 protected areas (&gt; 100 km²; 2001–2024) and trends in climate extremes and seasonality at 42 weather stations (1980–2024). EVI showed few significant long-term trends and no systematic shifts in phenology (start, peak or end of growing season) at individual reserves, despite strong seasonal cycles. Mixed-effects models across all reserves, however, detected small but significant decadal increases in EVI and a possible delay in the end of the growing season—a subtle signal not apparent in individual reserves. Maximum temperatures increased by 0.52°C decade⁻¹ and annual temperature range increased markedly, while mean annual precipitation showed no coherent national trend despite longer wet spells and higher extremes. These limited and spatially inconsistent changes suggest that increasing temperature extremes have not yet driven widespread or ecologically substantial vegetation responses in the protected areas examined. This is possibly because much of this vegetation is water-limited, precipitation has changed little nationally, and photoperiod may constrain growing-season timing shifts. A climate–EVI linkage analysis confirmed EVI responds to inter-annual climate variability, with precipitation anomalies the dominant predictor and temperature anomalies also significant, though climate explained only a modest fraction (<i>R</i>² = 12.4%) of reserve-level EVI variation. Where sustained rainfall declines did occur, such as at Springbok (−46 mm decade⁻¹), corresponding EVI declines were observed in adjacent protected areas, consistent with water availability as the dominant constraint in these systems.

In the present study, we address this knowledge gap by testing the relationship between landscape metrics and anuran assembly (richness, composition and ecological traits) in the Brazilian Cerrado. Using passive acoustic monitoring, we recorded 32 species in 31 breeding habitats of anurans (water bodies) located in the southwestern region of Goiás State, Brazil. Higher species richness was present in the breeding habitats within the more connected landscapes (landscapes with lower edge density and fewer native vegetation patches) and located farther from roads. Conversely, species richness decreased in landscapes with more native habitats. While habitat isolation caused by roads or agricultural lands negatively affects anuran diversity by hindering gene flow and recolonization between the terrestrial and breeding habitats, a phenomenon known as habitat split, particularly in species with low dispersal capacity and high sensitivity to desiccation. Small artificial reservoirs created for cattle management are frequently used by anurans as breeding sites. These reservoirs may play a crucial role in maintaining species richness, particularly for open-habitat species, despite the reduction of native vegetation in the landscape. We recommend that the effect of artificial reservoirs despite the surrounding native vegetation be addressed in future studies.
