Assessing the success of conservation translocation establishment: Post‐translocation demography of Nubian giraffe (Giraffa camelopardalis camelopardalis) in Uganda

Conservation Science and Practice
Conservation translocations are increasingly important for restoring and augmenting wild populations of extirpated species or those diminishing rapidly.

Demographic estimation methods for plants with dormancy [PDF]

, 2004
Demographic studies in plants appear simple because unlike animals, plants do not run away. Plant individuals can be marked with, e.g., plastic tags, but often the coordinates of an idividual may be sufficient to identify it. Vascular plants in temperate

Estimating long-term trends in abundance and survival for nesting flatback turtles in Kakadu National Park, Australia

Endangered Species Research, 2017
Flatback turtles Natator depressus are endemic to Australia and Papua New Guineaís tropical oceans and, although the species has an extensive distribution around northern Australia, there are few published long-term abundance trends of nesting ...

Spring migration of Ruffs Philomachus pugnax in Fryslân: estimates of staging duration using resighting data [PDF]

, 2010
Seasonal bird migration involves long flights, but most time is actually spent at intermediate staging areas. The duration of stay at these sites can be evaluated with mark–recapture methods that employ day-to-day local encounters of individually marked ...

Status and population dynamics of the Critically Endangered Valcheta frog Pleurodema somuncurense on the Patagonian Somuncura Plateau

Endangered Species Research, 2019
Amphibian populations are declining globally. In this scenario, detailed information on their ecology is crucial to determine the status and extinction risk of their populations and, therefore, better plan conservation activities.

Challenges and opportunities for monitoring wild Nile crocodiles with scute mark-recapture photography

Koedoe: African Protected Area Conservation and Science, 2018
The global conservation status of Nile crocodiles (Crocodylus niloticus) was last assessed in 1996. The species presents particular difficulty in monitoring because it can be cryptic, require expertise to handle, and caudal tail tags and transmitters are

Integrated population models: a novel analysis framework for deeper insights into population dynamics [PDF]

, 2018
Integrated population models (IPMs) represent the single, unified analysis of population count data and demographic data. This modelling framework is quite novel and can be implemented within the classical or the Bayesian mode of statistical inference ...
