Many plant communities across the world are undergoing changes due to climate change, human disturbance, and other threats. These community-level often tracked with use of permanent vegetative plots, but this approach is not always feasible. As an alternative, we propose using photogrammetry, specifically photograph-based digital surface models (DSMs) developed structure-from-motion, establish virtual plots in where structures may be possible.In 2021 2022, took iPhone photographs record species presence 1-m2 distributed alpine northeastern United States. We then compared field estimates percent coverage estimated DSMs.Digital can provide effective, minimally invasive, records coverage, while also allowing managers mark survey locations virtually for long-term monitoring. found that from DSMs did differ most substrates.In order continue surveying efforts areas or methods feasible, photogrammetry structure-from-motion a low-cost allows agencies accurately sensitive through time.

Abstract Habitat complexity has been considered a key driver of biodiversity and other ecological phenomena for nearly century. However, there is still no consensus over the definition or how to measure it. Up‐to‐date clear guidance on measuring urgently needed, particularly given rise remote sensing advent technologies that allow environments be scanned at unprecedented spatial extents resolutions. Here we review measured in ecology. We provide framework metrics habitat complexity, related concept heterogeneity. focus two most commonly used ecology: fractal dimension rugosity. discuss pros cons these using practical examples from our own empirical data simulations. Fractal widely used, critical examination it drawing research scientific fields. also informational their potential benefits. chart path forward by presenting, as guide, sets essential desirable criteria metric should possess.

There is a growing need for improved techniques to monitor coral reef restoration as these ecosystems and the goods services they provide continue decline under threats of anthropogenic activity climate change. Given difficulty fine-scale requirements survival spread outplanted branching fragments, Unoccupied Aerial Systems (UASs) an ideal platform spatially document quantitatively track growth patterns on shallow systems. We present findings from monitoring combining UAS data with object-oriented segmentation open-source GIS analysis quantify areal extent species-specific coverage across ~one hectare fringing over one-year period (2019–2020) in Laughing Bird Caye National Park, southern Belize.

Ocean biodiversity loss is being driven by several anthropogenic threats and significant efforts are required to halt losses promote healthy marine ecosystems. The establishment of a network Marine Protected Areas (MPAs) can help restrict damaging activities have been recognised as potential solution aid conservation. When managed correctly they deliver both ecological socio-economic benefits. In recent times, MPA designations increased rapidly while many countries set future targets for the decades ahead. An integral element management adequate monitoring that collects data assess if conservation objectives achieved. Data acquired vary widely techniques employed collect such data. Ideally, non-destructive non-invasive methods preferred prevent damage habitats species, though this may rule out number traditional extractive sampling approaches dredges trawls. Moreover, advances in ocean observation technologies enable collection large amounts at high resolutions, automated processing beginning make analyses more logistically feasible less time-consuming.

Coral populations are being progressively thinned by climate change, which elevates the risk of reproductive failure from Allee effects during fertilization. Studies have shown that fertilization success improves more intense and synchronized spawning, but local dependence on coral density remains unknown in wild populations.

Climate change is transforming coral reefs by increasing the frequency and intensity of marine heatwaves, often leading to bleaching mortality. Coral communities have demonstrated modest increases in thermal tolerance following repeated exposure moderate heat stress, but it unclear whether these shifts represent acclimatization individual colonies or mortality thermally susceptible individuals. For corals that survive events, important understand how past responses impact future growth potential. Here, we track 1,832 leeward Maui through multiple heatwaves document patterns survivorship over a seven-year period. While find limited evidence at population scales, reduced time specific individuals indicative acclimatization, primarily stress-tolerant taxa Porites lobata . survived both no relationship between response three four studied. This decoupling suggests better indicator than coral’s history. Based on results, recommend restoration practitioners Hawaiʻi focus Montipora with proven track-record survivorship, rather devote resources toward identifying cultivating bleaching-resistant phenotypes lab. Survivorship followed latitudinal stress gradient, because this gradient was small, likely local environmental factors also drove differences performance sites. Efforts reduce human impacts low performing sites would improve future.
