Advancing conservation breeding programs for marine invertebrates

Conservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

Conservation Biology, EarlyView.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

Efecto de la densidad en cebo sobre el rendimiento productivo, la composición de la carne y el perfil de ácidos grasos de cerdos sacrificados con 110 kg de peso [PDF]

, 2011
El número de cerdos por cuadra y la densidad influyen sobre el rendimiento productivo (Edmons et al., 1998). Además, la densidad de cría puede afectar a la calidad de la canal y de la carne (Estevez et al., 2003), ya que una reducción del espacio ...

Expansión vertical de la ciudad: densidad urbana, ¿densidad humana?

Estudios: filosofía, historia, letras, 2018
El futuro de las ciudades plantea su densificacion y verticalizacion. Un incremento de la poblacion en menos superficie disminuye desplazamientos, el consumo de suelo y el gasto de energia, aunque a costa de la interaccion social y la salud mental. En el caso de la Ciudad de Mexico, favorecer la verticalidad exige una cuidadosa adecuacion al contexto ...

A global assessment of animal community responses to agricultural management

Conservation Biology, EarlyView.
Abstract Transitions in agricultural management through crop and noncrop diversification on intensively managed croplands or pastures have benefited biodiversity. However, the extent to which agricultural management benefits species communities present in undisturbed ecosystems remains largely unclear.

The preventive and treatment effect of Urtica dioica on astrocyte density in the CA1 and CA3 subfields of hippocampus in STZ induced diabetic rats [PDF]

, 2013
Several animal model studies have shown that Diabetes mellitus can affect on the activity of hippocampus astrocytes, but these studies reported controversial findings.

Estructura poblacional y producción de frutos del milpesos (Oenocarpus bataua Mart.) en el Pacífico colombiano

Biota Colombiana
El milpesos es una palma muy importante para las comunidades del Pacífico colombiano, pues el líquido derivado del macerado del mesocarpo del fruto se considera un alimento con alto contenido de vitaminas (nutracéutico).

Cualidades del paisaje construido de la vivienda y su impacto en la morfología y densidades de Bogotá

Revista INVI, 2019
Diferentes estudios internacionales han catalogado a Bogotá, Colombia, como una de las ciudades con mayor densidad del mundo, sin embargo, al interior esta densidad está matizada por las características diferenciales del paisaje construido de la vivienda.

Sugar provisioning increases parasitoid numbers in agroecosystems but may not reduce pest densities: A meta‐analysis

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our findings demonstrate that providing sugar sources reliably supports parasitoid populations and parasitism rate but does not systematically translate into improved pest suppression or yield gains. These results suggest that, for economic and practical reasons, sugar inputs at the edge of cultivated fields should be favoured.

Local canopy cover, shade tree identity and landscape tree cover shape leaf‐cutter ant nest density and herbivory in cacao agroforestry systems

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.
