Baleen whales are among the largest marine megafauna, and while mostly well-protected from direct exploitation, they increasingly affected by vessel traffic, interactions with fisheries, climate change. Adverse interactions, notably strikes fishing gear entanglement, often result in distress, injury, or death for these animals. In Atlantic Canadian waters, such negative ‘incidents’ consistently reported to animal response organizations but have not yet been analyzed relative spatial distribution of vessels. Using a database 483,003 whale sightings, 1,110 incident reports, 82 million hours maritime activity, we conducted spatiotemporal vulnerability analysis all six baleen species occurring Northwest Ocean developing an ensemble habitat-suitability models.

ABSTRACT The Clavicarpa species, valued for their pharmaceutical, ornamental, and economic importance, exhibit notable rarity endemism in the Karst areas of Yunnan‐Kweichow Plateau China. These species face significant threats from habitat loss fragmentation, leading to a decline biodiversity. To mitigate these threats, Maxent algorithm was employed analyze current future distribution patterns, with particular focus on influence climate variables predicting potential shifts assessing extinction risks under optimistic SSP1‐2.6 pessimistic SSP5‐8.5 socioeconomic scenarios. EC‐Earth3‐Veg, MRI‐ESM2‐0, MPI‐ESM1‐2‐HR models were utilized conservation status assessment project distributions four time periods: present, 2030s, 2050s, 2070s. minimum temperature during coldest month (Bio 6) identified as most critical environmental factor, influencing both contraction expansion. Our modeling indicates that regions such South, Central, East China, particularly east Aihui‐Tengchong line south Yangtze River, highest suitability within geographical coordinates 18° N–45° N 97° E–120° E. Conversely, change projections suggest expansion Impatiens claviger , tubulosa pritzelii apalophylla while guizhouensis wilsonii increased risks.

Radiometric vegetation indices are considered good indicators of health and can contribute to explaining its current future evolutions. This study is carried out in the arid mountain rangeland Toujane (southeast Tunisia). The aim predict how climate change will affect Soil-Adjusted Vegetation Index (SAVI) values under dryland conditions. Current SAVI analyzed using maximum entropy algorithm (MaxEnt). Canadian Earth System Model version 5 (CanESM5) represents data source two climatic scenarios. These last, called Shared Socioeconomic Pathways (SSP245, SSP585), concern four time periods (2021–2040, 2041–2060, 2061–2080, 2081–2100).
