Annual and Seasonal Rainfall Variability in Mozambique During the Nineteenth Century

International Journal of Climatology, EarlyView.
This paper presents the first annually and seasonally resolved reconstructions of nineteenth‐century rainfall variability for Mozambique derived from the analysis of extensive documentary evidence. It reveals spatially heterogeneous rainfall patterns with recurrent multi‐year droughts, episodic extreme wet events, and a strong coherence between ...

Digital surveillance of animals and nature recovery

People and Nature, EarlyView.
Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

NUMERICAL SIMULATION AND RELIABILITY SENSITIVITY ANALYSIS OF BIONIC KILLER WHALES’S LOAD CHARACTERISTIC

Jixie qiangdu, 2021
As a kind of bionic robot fish,bionic killer whale played an important role in ocean development and scientific investigation. Based on the flapping wing movement theory,the bionic killer whale’s mechanism was analyzed,its instantaneous load was ...

Relational knowing as method and practice

People and Nature, EarlyView.
Abstract This paper seeks to contribute to (re)building the capacity for embodied, place‐based relational knowing, transforming how we know and thus what we know. What is known, or sought to be known, is relations. How we know these relations is by already being in it: breathing, sensing, moving, listening, responding, affecting and being affected ...

A Public Dataset of Annotated Orcinus orca Acoustic Signals for Detection and Ecotype Classification

Scientific Data
Killer whales (Orcinus orca) exhibit significant ecological and genetic diversity, with three primary sympatric populations in the Northeast Pacific: Resident, Bigg’s (Transient), and Offshore. Each population is characterized by distinct foraging habits,

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Correlates of variability in killer whale stereotyped call repertoires. [PDF]

, 2005
Killer whales vocalisations include repertoires of stereotyped call types (Ford 1984). There is strong evidence that these vocalisations are learnt (Hoelzel and Osborne 1986; Bain 1989; Deecke et al. 2000; Yurk et al. 2002).
