This shift highlights the importance of species interactions as regulators of dune vegetation dynamics. The research describes the structural composition of this vegetation, emphasizing its role in the ecological succession of sandy dunes along the 98 km-long ridge formed at the eastern coast of the Baltic Sea. The findings contribute to understanding the complex relationships between different plant groups in dune ecosystems.
Grizzly bear and human interaction in Yellowstone National Park: An evaluation of bear management areas
Yellowstone National Park — 2013 — WHEDD4E63B075
Grizzly bears in Yellowstone National Park are significantly more likely to occupy areas with restricted human access, demonstrating the effectiveness of Bear Management Areas (BMAs) in reducing human-bear interactions. A study analyzing GPS location data from 2007 to 2009 found that bears were twice as likely to be within these zones when BMAs were closed compared to open periods. Even during times of low human activity, unrestricted access increased bear displacement, highlighting the impact of human presence on bear behavior. The research underscores the utility of management closures in balancing wildlife conservation and recreational access in high-traffic protected areas.

Habitat selection in a changing environment: the relationship between habitat alteration and Scops Owl (Aves: Strigidae) territory occupancy
Vineyard Landscape of Piedmont: Langhe-Roero and Monferrato — 2013 — WHEB462715AE4
Scops Owl (Otus scops) territories in northwest Italy, particularly in the high-density Monferrato region, thrive in stable agricultural landscapes with minimal changes since the mid-1950s. The study used maximum entropy (MAXENT) models to analyze habitat occupancy across 401 territories, revealing a preference for middle-altitude areas with intermediate slopes, riparian zones, and pasture-grasslands while avoiding woodlands and Robinia pseudoacacia shrublands. Comparison of landcover data from 2009 and 1954/55 in Monferrato highlighted that stable cropland-vineyard mosaics are critical for owl occupancy. Conservation efforts should prioritize preserving riparian zones and promoting pasture-grassland-friendly agricultural practices to mitigate habitat loss, a key threat to this European concern species.
Habitat selection of the pre-released giant panda in Wolong Nature Reserve
Sichuan Giant Panda Sanctuaries - Wolong, Mt Siguniang and Jiajin Mountains — 2013 — WHE715AC6EFB8
A pre-released giant panda exhibited strong preference for areas with high densities of new bamboo shoots, while avoiding regions with dense adult or dead bamboo, higher culm heights, and increased canopy cover. The study, conducted in Wolong Nature Reserve, found that proximity to water sources and shelter significantly influenced habitat selection, suggesting successful predator avoidance learning during pre-release training. Logistic regression identified new bamboo shoot density as the primary predictor of habitat use. Notably, the panda's home range (9.21 hm²) was substantially smaller than those of wild pandas in the reserve, highlighting the need for enriched training environments to promote larger territorial behavior in future reintroduction efforts.
Habitat use and ecological observations of the Ooldea dunnart (Sminthopsis ooldea) at Uluru–Kata Tjuta National Park, Northern Territory
Uluru-Kata Tjuta National Park — 2013 — WHE82B8956F9B
A rare insight into the Ooldea dunnart (Sminthopsis ooldea), a small and elusive marsupial, reveals that mulga woodlands are likely its key habitat. Over 16 years of surveys at Uluru–Kata Tjuta National Park, researchers captured 37 individuals, most in pitfall traps, confirming spring breeding. While captures were inconsistent across habitats, they remained stable in one mulga-dominated site. Surprisingly, fewer dunnarts were found during the two wettest years, suggesting that rainfall may not be a primary driver of their presence. Fire also had no clear impact on their distribution. The study highlights the need to further explore the biotic and abiotic factors shaping this species' demography.
Habitat use by mountain nyala Tragelaphus buxtoni determined using stem bite diameters at point of browse, bite rates, and time budgets in the Bale Mountains National Park, Ethiopia
Bale Mountains National Park — 2013 — WHE3E68CB4E9B
Mountain nyala (Tragelaphus buxtoni) exhibit significantly lower foraging costs and greater efficiency in grasslands compared to woodlands, as evidenced by larger stem bite diameters at the point of browse (dpb), higher bite rates, and reduced induced vigilance. Adult females demonstrated the highest bite rates, while Solanum marginatum was identified as a preferred browse species with the greatest dpb. These findings suggest that grasslands provide superior foraging conditions for mountain nyala, offering both greater safety and more time dedicated to feeding. The study employed non-invasive techniques—focal animal observations along transects—to quantify habitat-specific foraging behaviors, bite rates, and time budgets across sex-age categories. Such behavioral indicators and natural giving-up densities (GUDs) offer valuable insights for conservation strategies, particularly for endangered species like the mountain nyala.

Hebron (Al-Khalīl)
Hebron/Al-Khalil Old Town — 2013 — WHE8CDEB257CA
Hebron (Al-Khalīl) experienced significant urban transformation from its peak prosperity in the 11th–10th century BCE to its modern layout. The city's decline began towards the end of the 10th century BCE, with a new settlement emerging in the valley during the Persian period (mid-6th century BCE), lacking defensive walls. Post-Islamic conquest, Hebron shifted from a Byzantine-Christian character to an Islamic one, centering around the Sanctuary, which evolved from a basilica into a mosque and Muslim shrine. Urban growth expanded northward, particularly under Mamlūk rule, with markets and dense settlements forming in the valley of al-Khalīl by modern times. This study reconstructs Hebron's historical urban development using archaeological and inscriptional evidence, highlighting its transitions through different periods—Bronze Age, Persian, Islamic, Crusader, and Mamlūk—while emphasizing its cultural and religious shifts.

A bust of a young man with curly hair and a conical cap was unearthed during excavations at the Early Roman House in Nea Paphos, Cyprus. The discovery sparks debate over its identification, with strong evidence suggesting it could represent one of the Dioskouroi (divine twins) or Attis, a figure from Phrygian mythology. While both theories are compelling, the study does not conclusively resolve the ambiguity, highlighting the interpretative challenges in ancient iconography.
Heterogeneous Preferences for Winter Nature-Based Tours in Sub-Frigid Climate Zones: A Latent Class Approach
Shiretoko — 2013 — WHE7974E07DC7
Winter nature-based tours in sub-frigid climate zones, such as Shiretoko, Japan, cater to distinct visitor preferences that can be segmented into three groups. One group prioritizes wildlife observation, particularly rare eagles and detailed interpretation, while another favors adventure-focused drift ice experiences with little interest in eagles or guided explanations. A third segment falls between these extremes. This heterogeneity suggests that tour operators should tailor offerings to specific preferences rather than assuming universal appeal, ensuring both visitor satisfaction and profitability.
High prevalence ofLeucocytozoonspp. in the endangered yellow-eyed penguin (Megadyptes antipodes) in the sub-Antarctic regions of New Zealand
New Zealand Sub-Antarctic Islands — 2013 — WHE32A4CC6D09
A high prevalence of Leucocytozoon spp. infection, particularly on Enderby Island, is linked to significant chick mortality in endangered yellow-eyed penguins (Megadyptes antipodes). The study found that 73.7% of adult penguins from Enderby Island tested positive for the parasite during the 2006/07 breeding season, with histological evidence confirming infection in one chick. This prevalence contrasts sharply with lower rates on Campbell Island (21%) and mainland New Zealand (11%). Genetic analysis revealed that Leucocytozoon in Enderby penguins is distinct from other populations, suggesting localized adaptation or transmission dynamics. While the exact role of the parasite in mortality remains unclear, these findings highlight its potential as a contributing factor to population declines.
