Testing the delivery of conservation schemes for farmland birds at the farm-scale during winter, in Southern lowland England [PDF]

, 2013
Many farmland bird species across Europe have continued to show population declines since the 1970s, as a result of agricultural intensification. A large number of conservation schemes and initiatives have emerged from Government and the food industry ...

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

The Anatomical Record, EarlyView.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

Restoration priorities to achieve the global protected area target

Conservation Letters, 2019
With much of Earth's surface already heavily impacted by humans, there is a need to understand where restoration is required to achieve global conservation goals.

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

The Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.

Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

The Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

U.S. Conservation Policy Reconsidered [PDF]

Research related to the Endangered Species Act tends to take the presence of that policy as given and focus on issues of implementation and effects. This paper seeks to reconsider U.S. conservation policy entirely.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Ecological and Habitat Restoration for Insect Conservation

Ecological restoration, the process of assisting the recovery of an ecosystem, can benefit insect conservation. The restoration of native plant species is often associated with natural recovery of insects, firstly phytophagous and pollinators. Restoration can also specifically aim at assisting the recovery of a particular insect taxon: meadows reopened

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

The Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

The WTP for property rights for the Giant Panda: can a charismatic species be an instrument for conservation of natural habitat? [PDF]

, 2002
The paper presents the results from a stated preference study to address issues concerning the potential for using flag-ship species, such as the Giant Panda, to purchase the property rights for the conservation of natural habitat. The study finds, first,
