Summary: The spatial capture-recapture model outperforms distance sampling in abundance estimation and is more robust to model specification. When using spatial capture-recapture for abundance estimation, researchers should consider factors such as identifiable individuals, multiple occasions of line transect surveys, imperfect detection of individuals on transects, and the assumption of closed demography of the population of interest.

Summary: Conducting biodiversity surveys using a fully randomised design can be difficult due to budgetary constraints, site accessibility, and other constraints. The commonly used biodiversity estimators may not perform well when applied to non-independent sampling of individuals. In this study, a Markov chain model is utilized to account for non-independence in sequential sampling, and the estimators perform reasonably well in empirical tests.

Summary: When surveying Geoffroy's spider monkeys in a flat landscape of tropical forest with homogenous visibility, line-transect sampling was found to be more efficient than point-transect sampling. However, when controlling for the size of the survey area, more spider monkeys were detected at point transects. More monkey detections were made during the first 10 minutes than during the second and third 10-minute periods of point-transect surveys.

Summary: This paper proposes a double branch fusion network based on UAV inspection images to improve the detection accuracy of vital components and defects in transmission lines. The network consists of a combination of a convolutional neural network (CNN) and a Transformer network, which extract local and global information respectively. To solve the semantic differences and feature aliasing problem, the paper introduces multiscale convolution and pooling modules. The network also includes a residual-like convolution module and performs feature fusion in multiple regions to enhance the multi-scale adaptability.

Summary: Wildlife abundance surveys are crucial for nature conservation and management decisions. However, monitoring cryptic and nocturnal mammals can be challenging. In this study, a novel monitoring method using an aerial drone with laser rangefinder and high zoom capabilities was proposed. The drone method outperformed traditional spotlight count surveys in recording hare density and coverage area.

Summary: The LAMOST Medium-Resolution Spectroscopic Survey (LAMOST-MRS) has provided a unique opportunity to detect multiline spectroscopic systems. Through analysis of over 1.3 million LAMOST DR7 MRS blue-arm spectra, 3133 spectroscopic binary (SB) and 132 spectroscopic triple (ST) candidates were identified, with over 95% being newly discovered. Interestingly, all ST candidates were found to be on the main sequence, while around 10% of the SB candidates may have components on the red giant branch.

Summary: Double-line spectroscopic binaries (SB2s) are an important class of spectroscopic binaries for studying star formation and evolution. Searching for SB2s has been a popular topic in astronomy, but limitations in automation and accuracy still exist. In this study, a convolutional neural network model was developed to search for SB2 candidates by detecting double peaks in the cross-correlation function (CCF) in LAMOST medium-resolution survey (MRS) data. The model achieved an accuracy of 97.76% and successfully identified 728 candidate SB2s, including 281 newly discovered ones.

Summary: Habitat destruction and over-hunting pose a growing threat to arboreal primates in Central Africa. Accurate assessments of primate density, abundance, and spatial distribution are crucial for effective conservation strategies. The method of choice, line transect distance sampling, is affected by disturbance caused by human observers, leading to underestimated densities.

Summary: The Nilgiri tahr, an endangered mountain ungulate endemic to the Western Ghats of India, faces threats from habitat fragmentation, hunting, and a limited range. A recent survey in the Anamalai Tiger Reserve suggests that the population of this species is stable in this protected area, which harbors 20-25% of the global population of the Nilgiri tahr.

Summary: George Drevar, a merchant captain who survived a shipwreck, was tried in 1881 for libel and threatening the life of Henry Cadogan Rothery due to a disagreement over the existence of the sea serpent. His actions were driven by mental illness and a fervent religious belief in the sea serpent.
